  Drei Vorteile der LED-Hochregalbeleuchtung
Posted by: bfiwi256 - 08-17-2021, 08:20 AM - Forum: Welcomes and Introductions - No Replies

In der Welt der Beleuchtung ist das Hochregal eine Vorrichtung, die man in einem Lagerhaus, einer Fabrik, einer Sporthalle oder einem anderen großen offenen Bereich mit relativ hohen Decken findet. In vielen bestehenden Beleuchtungsanlagen für Hochregale und Tiefregale werden HID-Lampen (High Intensity Discharge) wie Halogen-Metalldampflampen oder Natriumdampf-Hochdrucklampen verwendet.

Trotz ihrer weiten Verbreitung verwenden HID-Lampen eine veraltete Technologie, die Gebäudeverwalter sowohl direkt als auch indirekt Kosten verursacht. Insbesondere die Verwendung von HID-Lampen führt zu höheren Energiekosten als nötig, zu häufigen Wartungskosten und zu einer schlechten Beleuchtungsleistung. All diese Probleme können durch die Umrüstung Ihrer vorhandenen Beleuchtung auf LED linear light gelöst werden.

Energieeinsparung
Energieeinsparungen sind einer der Hauptgründe, warum Sie LED tri-proof light für Ihr Gebäude oder Ihre Anlage in Betracht ziehen sollten. Gängige Wattzahlen für LED-Hochregalbeleuchtungen reichen von 95 bis 495 Watt. Vergleicht man diese Wattzahl mit einer typischen HID-Hochregalbeleuchtung, so liegt der gleiche Bereich zwischen 175 und 1000 Watt.

Wenn Sie also auf LED trunk linear umsteigen, reduzieren Sie Ihren Energieverbrauch sofort um 40-60 %. In Dollar ausgedrückt bedeutet dies, dass Sie durch die Umstellung auf LED-Beleuchtung 300 Dollar pro Leuchte und Jahr an Stromkosten einsparen würden. Je nach Größe Ihrer Einrichtung kann sich dies erheblich auf die Betriebsbilanz auswirken.

Senkung der Wartungskosten
Durch die Umstellung auf LED down light werden Sie auch eine drastische Verringerung der Wartungskosten für Ihre Hochregalbeleuchtung feststellen. Dies liegt an der Art und Weise, wie LEDs Licht erzeugen, und an der Art und Weise, wie sie ihre Funktionsdauer verlängern. Die von LEDs erzeugte Lichtleistung nimmt im Laufe der Zeit nur sehr langsam ab, so dass sie nicht mehr ordnungsgemäß funktioniert, sobald eine Brennstoffquelle deutlich reduziert wird. Infolgedessen kann die Lebensdauer eines LED-Produkts wesentlich länger sein als die einer HID-Lampe, wodurch sich der Wartungsaufwand drastisch verringert.

Durch die Umrüstung einer herkömmlichen 400-W-HID-Hochregalbeleuchtung auf LED kann ein typisches Gebäude mit industriellen Beleuchtungskörpern über einen Zeitraum von drei Jahren allein bei den Wartungskosten bis zu 5.341 $ einsparen.

Beleuchtungsleistung
Schließlich ist die Beleuchtungsleistung ein entscheidender Faktor bei der Bewertung der Umstellung auf eine andere Art von Beleuchtung. Vom Standpunkt der Leistung aus gesehen sind LEDs ihren HID-Gegenstücken haushoch überlegen.

LED panel lights verwenden ein Mehrpunktdesign, d. h. sie verteilen das Licht gleichmäßig auf der vorgesehenen Oberfläche. Daher variieren die Lichtstärken auf einer bestimmten Fläche weniger zwischen den verschiedenen Montageorten der Beleuchtungskörper. Zusätzlich zur gleichmäßigen Verteilung des Lichts sind LED high bay lights in einer Reihe von CCTs (korrelierte Farbtemperaturen) erhältlich und bieten daher eine Reihe von Optionen, um die visuelle Wahrnehmung der "Helligkeit" zu erhöhen.

Im Gegensatz dazu erzeugen HID-Scheinwerfer einen hellen Fleck" direkt unter dem Scheinwerfer, wobei die Lichtstärke mit zunehmendem Abstand zwischen den Scheinwerfern drastisch abnimmt.

Fazit
Abschließend können wir feststellen, dass es drei Hauptgründe gibt, die für eine LED-Umrüstung in Ihrer Einrichtung sprechen. Durch die Umrüstung werden Sie sofortige Energieeinsparungen, eine geringere Häufigkeit der Beleuchtungswartung und eine Verbesserung der Gesamtbeleuchtungsleistung feststellen. Erfahren Sie, wie eine LED-Retrofit-Anlage für Sie geeignet sein könnte - kontaktieren Sie Stouch Lighting noch heute und wir würden uns freuen, Ihnen eine kostenlose Einschätzung Ihrer Anlage zu geben.

  What is the LED Batten light?
Posted by: bfiwi256 - 08-17-2021, 08:19 AM - Forum: Welcomes and Introductions - No Replies

LED batten lights have come along way in the last few years with the technology of LED, now batten lights have loads of different options as oppose to every batten being 2 x 36 fluorescent battens. LED battens now are much more streamlined with a slim and minimalist look but yet still put out the same brightness, this is great because 4 foot fluorescent battens are a real eye saw but now with LED battens they can manipulate the fittings to give a much cleaner and less commercial look. The best thing about battens is they are super practical with a real bright light and wide beam angles. When buying your LED upton batten lights there are a few considerations to make so in this blog I will run through what questions to ask before buying and our favourite best selling LED general batten lights.

IP Rating - The IP rated refers to the light being suitable for indoor or outdoor. If your application is outdoors then go with IP66, this is a high rating which will protect from water and dust. If you are buying for indoor you can still go with a IP66 as it will still protect from dust and physical impacts, otherwise an IP20 is fine as well with most batten still sealed. 
LED - There are still loads of fluorescent batten and tubes out there with people still replacing the tubes and ballasts, this is a bad idea as you can now buy for T8 LED direct replacement tubes. LED Battens use 70% less power and last 10 times longer than fluorescent tubes, LED tubes also now perform better in brightness and imitate a fluorescent tube without you knowing the difference. So always go with LED for all these reasons. LED tube lights are also much safer and better for the environment with fluorescent tubes containing mercury.
Integrated LED or LED Tubes - Most LED battens sold today are integrated which means once the light batten dies basically throw it out which isn't ideal as you will need to replace and get an electrician to come back and replace, this can cost around $200 with the call out fee. When a manufacturer makes something integrated they can make it better with heat sinks and pushing up the performance as there is only so much technology you can fit into a tube. So if you are buying a LED integrated batten, only buy from quality brands, buying from LiteHome these brands means you are buying from a manufacturer with strict quality control. Avoid cheap brands as you will only get headaches and they maybe not even comply. When buying anything, I think practical and purchasing a batten with LED T8 tubes means you can always replace the tubes yourself so literally can't go wrong, however with T8 battens, they look much more bulky and commercial, with LED integrated battens they much more slimline.
Colour Temperature - This is crucial to get right if you are installing LED battens in work environments such as garages, car parks, warehouses, workshops, kitchens etc, you should always look to use a temperature of a minimum 5000k as this colour spectrum reacts with the brain most in keeping alert and active. If your application needs to suit a heritage or traditional set up then you could look to use a 3000k or 4000k per perfuably and this will soften the light to create more ambience and warmth.


LED Linear light is a phrase we often hear in the realms of commercial interior design, but what exactly does it mean and how do we use it? This article aims to ‘de-mystify’ commercial LED Linear lighting and give you an insight into how and where to use it, to effortlessly turn cool offices into exceptional ones!

Firstly let’s talk about LEDs. An LED is short for ‘Light Emitting Diode’, which is a highly efficient long-lasting source of light that uses a semiconductor to convert electricity into light. When a suitable voltage is applied to the leads, electrons are able to recombine with ‘electron holes’ within the device, releasing energy in the form of photons (light). The colour of the LED trunk linear is determined by the energy band of the semiconductor.

  FIBC Jumbo Bags
Posted by: bfiwi256 - 08-17-2021, 08:17 AM - Forum: Welcomes and Introductions - No Replies

PP woven bags or jumbo bags are known as Flexible Intermediate Bulk Container Bags (FIBC bags). It is an economical and ideal packing used for the storage & transportation of powdered, granulated and bulk products like sand, fertilizers or plastic granules. FIBCs are most often made of thick woven polyethylene or polypropylene, either coated or uncoated. We are masters in making polypropylene texture/fabric in a type of cubic bags.
Rectangular jumbo Bags are easy for storing and carrying solid material. Also, these are resistant to any sort of physical damage. They don't cause any harm to the material while carrying in the bag. With a large storage capacity, these jumbo bags are ideal for carrying huge material in a convenient and simple manner.
U-Panel jumbo bags are constructed with three main body components – one that runs the full length of the bag forming the bottom and two sides (the “U”) and two additional pieces of fabric sewn between the U on two sides (the “Panel”). Generally, U-panel bags will maintain a square shape when filled, especially with the addition of internal baffles. U-panel bags are an industry standard and the most popular type of construction.
Baffles are pieces of fabric that are sewn to the inside corners of a bag to maintain its cube shape after filling. The baffles have holes that allow the product to flow freely through them. The baffles also prevent the bag from bulging, which makes the baffle jumbo bag stand up straight and in turn allows the bags to be more efficient in their use of space.  Net and tie baffles are another type of baffle option, but not as common.
Type C jumbo Bags are known within the industry as conductive or groundable Bulk Bags or conductive jumbo bags. Constructed from non-conductive polypropylene material interwoven with conductive yarns that form a grid pattern, these are designed to control electrostatic charges by grounding. The inner or outer surfaces of the FIBC may have a thin coating. In this case, the breakdown voltage to the conductive threads must not exceed 6 kV to avoid propagating brush discharges The bag must be electrically grounded during filling and emptying - this is essential to the safe use and performance of a Type C bag.
Also called a tubular jumbo bag, the Circular Bag is made from fabric woven on a circular loom, which is then cut to the proper length for a specified bag height, thereby eliminating the vertical seams on each of the bag’s sides.  The tubular body design is ideal as a linerless option for fine and hygroscopic materials.  It is also an excellent alternative to the original four-panel bag construction.  

What are anti-static FIBCs, or anti-statics jumbo bags? They are large transport and storage bags that resist electrostatic charge. Their typical diameter when filled is 45 to 48 inches, which allows the bags to fit two across in a typical shipping container or truck. They are standardized containers and meet ISO standards.
FIBCs, or flexible indeterminate bulk containers, have the following characteristics:
1. They cannot be handled manually when they are filled.
2. They are intended for the transport of solid material, whether flakes, powder or grains.
3. They require no further packaging.
4. They are designed for lifting from above by their lift loops or straps.

  What Is Polyester Fabric?
Posted by: fowjw558 - 08-17-2021, 02:46 AM - Forum: Welcomes and Introductions - No Replies

Polyester is a synthetic fabric that’s usually derived from petroleum. This fabric is one of the world’s most popular textiles, and it is used in thousands of different consumer and industrial applications.
Chemically, polyester is a polymer primarily composed of compounds within the ester functional group. Most synthetic and some plant-based polyester fibers are made from ethylene, which is a constituent of petroleum that can also be derived from other sources. While some forms of polyester are biodegradable, most of them are not, and polyester production and use contribute to pollution around the world.
In some applications, polyester may be the sole constituent of apparel products, but it’s more common for polyester to be blended with cotton or another natural fiber. Use of polyester in apparel reduces production costs, but it also decreases the comfortability of apparel.
When blended with cotton, polyester improves the shrinkage, durability, and wrinkling profile of this widely-produced natural fiber. Polyester fabric is highly resistant to environmental conditions, which makes it ideal for long-term use in outdoor applications.
The fabric we now know as polyester began its climb toward its current critical role in the contemporary economy in 1926 as Terylene, which was first synthesized by W.H. Carothers in the UK. Throughout the 1930s and 1940s, British scientists continued to develop better forms of ethylene fabric, and these efforts eventually garnered the interest of American investors and innovators.
Polyester fiber was originally developed for mass consumption by the DuPont Corporation, which also developed other popular synthetic fibers like nylon. During World War II, the Allied powers found themselves in increased need of fibers for parachutes and other war materiel, and after the war, DuPont and other American corporations found a new consumer market for their synthetic materials in the context of the postwar economic boom.
Initially, consumers were enthusiastic about the improved durability profile of polyester compared to natural fibers, and these benefits are still valid today. In recent decades, however, the harmful environmental impact of this synthetic fiber has come to light in great detail, and the consumer stance on polyester has changed significantly.
Nonetheless, polyester remains one of the most widely-produced fabrics in the world, and it’s hard to find consumer apparel that doesn’t contain at least some percentage of polyester fiber. Apparel that contains polyester, however, will melt in extreme heat, while most natural fibers char. Molten fibers can cause irreversible bodily damage.
Ethylene Polyester
Ethylene polyester (PET) is the most commonly-produced form of polyester fiber. The primary component of PET is petroleum-derived ethylene, and in the process of creating polyester fiber, ethylene serves as the polymer that interacts with other chemicals to create a stable fibrous compound.
There are four ways to make PET fiber, and the polyester production process varies slightly depending on which method is used:
1.Filament: Polyester filaments are continuous fibers, and these fibers produce smooth and soft fabrics.
2.Staple: Polyester staples resemble the staples used to make cotton yarn, and like cotton staples, polyester staples are usually spun into a yarn-like material.
3.Tow: Polyester tow is like polyester filament, but in polyester tow, the filaments are loosely arranged together.
4.Fiberfill: Fiberfill consists of continuous polyester filaments, but these filaments are produced specifically to have the most possible volume to make bulky products like pillows, outerwear, and stuffing for stuffed animals.
The process of creating polyester fiber begins with reacting ethylene glycol with dimethyl terephthalate at high heat. This reaction results in a monomer, which is then reacted with dimethyl terephthalate again to create a polymer.
This molten polyester polymer is extruded from the reaction chamber in long strips, and these strips are allowed to cool and dry, and then they are broken apart in to small pieces. The resulting chips are then melted again to create a honey-like substance, which is extruded through a spinneret to create fibers.
Depending on whether filaments, staple, tow, or fiberfill fibers are desired, the resulting polyester filaments may be cut or reacted with various chemicals to achieve the correct end result. In most applications, polyester fibers are spun into yarn before they are dyed or subjected to other post-production processes.
PCDT Polyester
The process of creating PCDT polyester is similar to the process of creating PET polyester, but this polyester variant has a different chemical structure. While PCDT also consists of ethylene glycol reacted with dimethyl terephthalate, different production processes are used to make these two common polyester variations.
Plant-Based Polyester
Most types of plant-based polyester are also made from ethylene glycol reacted with dimethyl terephthalate. While the source of the ethylene used in PET and PCDT polyester is petroleum, however, producers of plant-based polyester use ethylene sources like cane sugar instead.
[color=rgba(0, 0, 0, 0.8)]Chiffon fabric [/color]
Chiffon fabric was first made in France, but the production of this substance expanded worldwide as the Industrial Age picked up steam. By the first few decades of the 1900s, silk chiffon was in relatively wide production in the United States, and producers of this fabric in America were starting to show interest in replacing silk with another material for chiffon production.
Crepe fabric 
Crepe fabric has no clear origin point in the history of human civilization. Since the concept behind crepe is so simple, many cultures have adopted forms of this fabric at one stage of development or another. For instance, Crepe is still used by Orthodox Greek women for mourning, and various cultures of the Indian subcontinent incorporate crepe into their traditional garments.
Satin Fabric
Satin Fabric refers to the weave of the fabric rather than the material. Satin is one of the three major textile weaves, along with plain weave and twill. The satin weave creates a fabric that is shiny, soft, and elastic with a beautiful drape. Satin fabric is characterized by a soft, lustrous surface on one side, with a duller surface on the other side. This is a result of the satin weaving technique, and there are many variations on what defines a satin weave.
Polyester is not biodegradable
The majority of polyesters are not biodegradable, meaning that the polyester fabric shirt you bought last season will not decompose for 20 years at best and 200 years at worst.
What’s more, polyester is partially derived from petroleum, and the oil manufacturing industry is the world’s largest pollutant.
Polyester dyes are not sustainable
Ever notice how polyester fabrics are stain-resistant? That’s because it takes a special kind of dye to colour polyester successfully. These dyes, known as disperse dyes, are insoluble in water. Like polyester, they are made up of a complex molecular structure that does not readily decompose.
Wastewater from textile factories containing leftover dye is difficult to treat. When it enters the environment, its toxicity causes serious problems to local plant and animal life.
In addition to causing environmental problems, polyester dyes are toxic to humans. Dye workers worldwide report higher incidences of cancers and lung disease than the general population.
Polyester manufacturing is water-thirsty
Acetate imitation fabric is created through an energy-intensive heating process and requires large quantities of water for cooling. If not managed properly, this can result in groundwater levels dropping and reduced access to clean drinking water, particularly in vulnerable communities where polyester is often manufactured.
More on those microfibres
Multiple studies have shown that synthetic fibres make up a good share of microplastics found in waters and are widely implicated as the source of pollution. It’s been suggested that more than 4,500 fibres can be released per gram of clothing per wash, according to the Plastic Soup Foundation.
Microfibres are so tiny they can easily move through sewage treatment plants. They do not biodegrade and bind with molecules from harmful chemicals found in wastewater. They are then eaten by small fishes and plankton, concentrating toxins and going up the food chain until they reach us. The consequences of microfibres on the human body have yet to be researched and revealed. Until then, here are our top tips on dealing with microfibres in clothing.
What Is Polyester Used For
Georgette printed fabric, as we all know, is often used for clothing, nowadays its more common to find blended cotton and polyester than full polyester. The main reason for this is the lack of breathability in pure polyester, and frankly few people like the look now. Blended fabrics also retain many of the benefits of polyester; being more resistant to wrinkling, having more stretch, and sometimes more resistant to wear.
Outside of fashion, polyester is used for a great variety of products; the most common being plastic bottles and containers. Some others include sailcloth, canoes, tarpaulin, LCDs, insulating tapes, various items for film, ropes, cord, and more. Polyester is also commonly used as a finish to high-quality wood products like pianos, guitars, and vehicle interiors (which is then polished to a glossy, durable finish).

  HOW DO GLOW PLUGS WORK?
Posted by: fowjw558 - 08-17-2021, 02:45 AM - Forum: Welcomes and Introductions - No Replies

No matter how you look at it, car technology has come on leaps and bounds over the past decades. And, while some of these advances are immediately noticeable and appreciated, such as electric windows and smoother suspension systems, others, like glow plugs, are hidden under the bonnet and forgotten about unless something goes wrong. This shouldn’t be the case. Heat glow plug technology has significantly improved, with BERU, for example, dramatically improving the time it takes to start your diesel car – especially on cold mornings.
So, let’s appreciate the hidden and take a look at BERU glow plugs – what are they, the different types available and how they compare to the competition.
What is a glow plug?
To get started, we need to go back to basics: what is a glow plug? And, what does a glow plug do?
A glow plug is a heating element that heats incoming fuel and air to encourage efficient fuel combustion in a diesel engine. The fuel combustion starts your engine so that you can drive. Each cylinder of your engine has one glow plug, either in the pre-chamber (pre-chambered engines) or in the combustion chamber (direct-injection engines).

GLOW PLUG SYSTEMS
The starting process of an engine heavily influences the exhaust gas values of a vehicle. Together, glow plugs and their connected components (glow plug control modules, glow plug relays and glow plug combustion sensors) play an important role in reducing emissions helping to protect the environment.

Glow plug is specialized heating devices used to aid in the starting of diesel engines. They are similar to spark plugs in design; however, they differ in their primary function. Instead of producing a timed spark to ignite the fuel mixture, like spark plugs do, glow plugs simply serve to produce additional heat that aids the diesel engine combustion process during cold starts.
Diesel engines rely entirely on the heat generated by cylinder compression to ignite the fuel mixture. When glow plugs begin to fail, this additional heat that aids the combustion process is gone, and the engine may become more difficult to start, especially in cold weather.
Another symptom of faulty glow plugs is black smoke being observed during start up, indicating the presence of unburned fuel due to an incomplete combustion process. In this guide, we will cover how to test the resistance of glow plugs to determine if they are functioning properly.
Part 1 of 1: Testing your glow plugs
tep 1: Determine the multimeter’s resistance value. Before testing the terminals, you must determine the resistance value of your digital multimeter. To do this, turn the multimeter on, and set it to read in Ohms.
Once the multimeter is set to read in Ohms, touch the two leads of the multimeter together and examine the resistance reading that is displayed.
If the multimeter reads zero, try changing the setting of the multimeter to a higher sensitivity until a reading is obtained.
Record this value on a piece of paper, as this will be an important value in calculating the resistance of your glow plugs later on.
Step 2: Locate the glow plugs in your engine. Most glow plugs are installed in the cylinder heads and will have a heavy gauge wire, similar to a regular spark plug wire, attached to them.
Remove any covers that may be obstructing access to the glow plugs, and use the flashlight for additional illumination if necessary.
Step 3: Disconnect the glow plug wires. Once all of the glow plugs have been located, disconnect any wires or caps attached to them.
Step 4: Touch the negative terminal. Take your multimeter and touch the negative leads to the negative terminal on your vehicle’s battery.
If possible, secure the lead to the terminal by tucking it inside or underneath the clamping mechanism of the post.
Step 5: Touch the positive terminal. Take the positive lead of your multimeter and touch it to the terminal on your Mitsubishi glow plugs.
Step 6: Record the glow plug’s resistance. With both leads touching the terminals, record the resistance reading that is indicated on the multimeter.
Again, the reading that you get should be measured in Ohms (Ω).
If no reading is obtained when you touch the glow plug, make sure that the negative lead is still in contact with the negative battery terminal.
Step 7: Calculate the resistance value. Calculate the true resistance value of the glow plug by subtracting.
The true resistance value of the glow plug can be determined by taking the resistance value of your multimeter (recorded in Step 2) and subtracting it from your glow plug resistance value (recorded in Step 6).
Step 8: Evaluate the resistance value. Compare your calculated true resistance value of your glow plug with the factory specification.
If the glow plug resistance exceeds the specification or falls out of the acceptable range, then the glow plug must be replaced.
Step 9: Repeat for other glow plugs. Repeat the procedure for the remaining glow plugs, until they have all been tested.
If any of the glow plugs fail the test, it is recommended that the entire set be replaced.
Replacing just one, or a few, of the glow plugs may cause engine problems similar to a faulty glow plug if the resistance readings are too far apart.
For most vehicles testing the resistance of a glow plug is a pretty simple procedure, granted the glow plugs are in an accessible location. However if they are not, or this task is not something that you feel comfortable taking up on your own, this is a service that any professional technician, such as one from YourMechanic, should be able to perform quickly and easily. If necessary, they can also replace your Isuzu Glow Plugs so that you can start your car like normal.
There are very few glow plugs that are considered universal plugs (OS' #8 plug is an example). For the most part, the type of fuel you are running will impact the kind of glow plug you need to use. Another component in the nitro fuel is nitromethane. The Nitro Percentage of your fuel determines the ignition point as well; in other words, the more nitro you run, the more you advance the ignition point. Ideally, the ignition point will be when the engine is at top dead center (TDC). This will force the piston down and back up again for another stroke. But when you run higher nitro content and don't switch to a colder plug, you will advance the ignition point and result in less-than-optimum performance, since the piston is still on its compression stroke (the upward stroke) when the air/fuel mixture is ignited.
In general, the higher the the nitro percentage, the colder the plug should be. Conversely, the lower the nitro percentage, the hotter the plug should be.
Glow plugs are an engine management component that is found on vehicles equipped with diesel engines. Their purpose is to preheat, and help warm up the engine’s cylinders so that diesel combustion can occur more easily. They play an especially important part in warming the vehicle’s cylinders during cold starts, where starting the engine is most difficult. Glow plugs use an electrode which will warm up and glow orange when current is applied. When the glow plugs have an issue, they can usually cause problems with the driveability of the vehicle. Usually bad or failing glow plugs will produce a few symptoms that can alert the driver of a potential issue.
1. Engine misfires or decrease in power and acceleration
Engine misfires are one of the first symptoms of an issue with the vehicle’s glow plugs. If the Mazda Glow Plugs malfunction they will not provide the additional heat that aids in diesel combustion, which may cause the engine to experience misfires. The misfires may cause a loss in power, acceleration, and even fuel efficiency.
2. Hard starting
Another symptom of an issue with the vehicle’s glow plugs is hard starting. Unlike gasoline engines, which use a spark to ignite the fuel mixture, diesel engines rely solely on cylinder pressures to ignite the diesel fuel mixture. If the glow plugs fail, the engine will have to overcome additional pressure in order to ignite the mixture, which may result in hard starting.
3. Black smoke from the exhaust
Another symptom of an issue with the glow plugs is black smoke from the exhaust. Faulty glow plugs may disturb the sensitive diesel combustion process, which may cause the engine to produce black smoke from the tailpipe. Black smoke can also be caused by a wide variety of other issues, so having the engine properly diagnosed is highly recommended.
Glow plugs are found on virtually all diesel engines, and play an important role in starting and operating the engine. If your vehicle is displaying any of the symptoms above, or you suspect that your glow plugs may be having an issue, have the vehicle inspected by a professional technician, such as one from yourMechanic, to determine if the glow plugs need to be replaced.
Continuous Improvement
The diesel engine is continuously being improved, in terms of its fuel consumption, power outputs and, ultimately, refinement. Drivers of modern diesel vehicles expect to be able to just jump in, turn the key and go. It’s no longer acceptable to have to wait 8 to 10 seconds for a glow plug light to go out before you can start the engine. One of the reasons this is possible is because of the technical advances that have been made in glow plug design, in particular with the development of both twincoil technology and the latest third generation of glow plug – the New High Temperature Ceramic type, or NHTC. In this article we take a closer look at these latest types of plugs in more detail; the manufacturers spearheading the new technologies, and the major motor manufacturers adopting them as OE.
Twin -coil Technology
Using twin-coil technology, Toyota Glow Plugs can be made to heat more quickly and then self-stabilise at the correct temperature. This type of plug is more resistant to misuse, as it will prevent overheating of the main coil and allows longer post glow periods, giving cleaner exhaust emissions.
Each twin-coil glow plug has been designed and tested to 7,000 heating cycles before being approved for production. This means that if the engine is started from cold twice per day, the glow plug could have a life expectancy of 10 years or more.
Glow plugs are probably far more intricate than you may imagine them to be. It takes precision laser welding to join the heating coils, which are then tested for maximum temperature and rate of temperature rise. This is to ensure that the glow plugs reach 850°C within a specified time.

  Road Bike Vs. Mountain Bike
Posted by: fowjw558 - 08-17-2021, 02:44 AM - Forum: Welcomes and Introductions - No Replies

Breakthroughs in technology have made them much more efficient and comfortable while simultaneously making them much more affordable when it comes to cost to benefit ratios. This makes it a great time to buy a cycle!
The dilemma most people face when purchasing a bike is the type of bike to buy. Avid cyclists generally have a different bike for each different style of cycling that they will be doing, but hobbyists and recreationists can’t really afford to do that.
If you can only get one bike, what should it be?
Unfortunately, there isn’t a right answer to that question.
Everyone is different, and so are their needs. Most casual cyclists will want to purchase bike, but once you have the options narrowed down this far, it’s a matter of purpose and preference.
In this article, we can help you determine whether a road bike or a mountain bike is the better choice for your needs. We will take a look at some of the factors and circumstances that can help you to determine which choice would be more prudent.
By the end, you will be familiar with the questions to ask yourself before purchasing a bike and the type of things you can do with each bike.
Before you can compare the 2 different types of bikes, you need to be aware of your own cycling style. After all, knowing what you intend to use your bike for is one of the most important pieces of information to help you make your choice.
First, you should ask yourself how you will be using the bike.
Are you hoping to get some exercise without the shock to your joints that running provides?
Do you want to cruise and explore some of the trails nearby, or take it through some mountains?
Are you trying to cut down on time in traffic, so you want to use a bike to get around the city and replace your car for short-distance commuting? Do you hope to do more than one of these things with your bike?
Knowing your primary use will point you in the right direction. If you plan to stick to roads, then you may not need a mountain bike. Road bikes are great commuter bikes that can go pretty quickly and cover a lot of ground.
If you plan to use your bike for exploration as well as exercise and commuting, though, you will need the more versatile mountain bike.
Road bikes are optimized for pavement, so you can’t use them in the mountains. Their tires are very narrow and thin, so a single pebble or stick will send you flying head over heels.
It’s dangerous to use them on unknown or uneven terrain.
On the other hand, mountain bikes are not optimized for riding on the road, but they are capable of doing so as long as you put the extra effort into making them go.
They’re not as fast on the road, and they’re not as efficient, but unlike road bikes, which can’t take mountain paths at all, these bikes won’t put you in danger if you do ride them on the road… They just get a lot harder to handle and a lot less comfortable.
Now that you’ve (hopefully) determined how you’ll be using your bike, let’s take a look at these 2 bikes in more detail.
This will give you a better idea of all the things you can do with them.
Road Bikes
Road bike (occasionally known as racing bikes) are designed for speed.
These are great options for commuters because the narrow tires can roll very quickly along paved surfaces as long as there aren’t any obstacles in the way. They are becoming very popular and being made with disc brake.
These bikes have a few different types. Aero bikes are designed to minimize the drag you experience during a ride.
These are professional racing bikes that are more concerned with speed than comfort or other features. Ultralight bikes are designed for climbing uphill. They’re extremely lightweight but they’re not very versatile.
Endurance bikes are built more for touring racing. These are designed for riders who plan to travel longer distances per ride, with a focus on comfort over speed and climbing.
Mountain Bikes
These bikes are much more versatile and durable than road bikes. They’re made for handling dirt trails and different terrains.
These bikes have wider handlebars and usually come with forks that will absorb the shocks you take. They can handle pebbles and twigs and little bumps in the path without sending you flying.
These usually have wide tires and a lot of treads, so you will have traction when riding. They also include hydraulic disc braking and drivetrains that can handle steeper climbs and descents.
Hardtail bikes come with a rigid frame and suspension forks. These are the most common and most affordable ones.
They also make XC full suspension mountain bikes. These are for people who are not riding as far. The rear suspension on these bikes keeps the frame light so you can get extra efficiency when powering up climbs.
The trail full suspension bikes are for riding longer distances because they balance efficiency climbing with going downhill. These have wide tires and plenty of stopping power on the brakes. Finally, full suspensions put a lot of power in the rear wheel.
These can go for very long rides without causing exhaustion. They’re designed to be very balanced and handle any terrain for long rides.
Mountain bikes are very versatile. They can be used to ride just about anywhere – including roads. Some people like using them for unpaved roads. Others like using them to power up steeper hills without the same level of effort road bikes require.

E-bike
The first thing you should know about e-bikes is that they’re here to stay. Electric bike sales jumped by an incredible 145 percent from 2019 to 2020 alone, according to the market research firm NPD Group. It’s a nearly $244 billion industry as of last year, and there’s no sign of a slowdown.
Some view the rise of e-bikes as a threat, as though standard bikes will go the way of the penny-farthing once everyone goes electric. But fear not: E-bikes aren’t here to rob us of our human-powered way of life. In fact, they may very well enhance it—especially as travel and commuting habits change following the global pandemic and shift of work commuting. So as we roll our way into peak riding season, here’s everything you need to know about the electric revolution.
Generally speaking, E bicycle are bicycles with a battery-powered “assist” that comes via pedaling and, in some cases, a throttle. When you push the pedals on a pedal-assist e-bike, a small motor engages and gives you a boost, so you can zip up hills and cruise over tough terrain without gassing yourself. Called “pedelecs,” they feel just like conventional bikes—but better, says Ed Benjamin, senior managing director at the consulting firm eCycleElectric. “You control your speed with your feet, like with a regular bike,” he says. “You just feel really powerful and accelerate easily.”
In addition to the pedal-assist feature, some e-bikes come with a throttle that engages the motor with the press of a button. These belong to a separate class of e-bike that, obviously, doesn’t offer a pure cycling experience; they’re also illegal in some municipalities. Interestingly, Benjamin says, people who aren’t already “cyclists” tend to gravitate toward throttle bikes at first, but then turn around and choose a pedal-assist for their next purchase.
“People are buying electric bicycle as a way to reduce car trips,” Benjamin says. The data backs him up: 28 percent of survey respondents said they bought an e-bike specifically to replace driving a car. And many other reasons buyers listed for wanting an e-bike—including carrying cargo and kids, avoiding parking and traffic, and environmental concerns—also indicate a desire to get out from behind the wheel. Plus, you don’t need to change clothes or clean up when you arrive at your destination, because you don’t have to work up as much of a sweat.
Consider, too, that more than half of all driving trips are shorter than 10 miles, with some surveys reporting that the average single trip amounts to just 5.95 miles. That’s a no-brainer distance to cover by e-bike. In fact, the survey found that owners replaced 46 percent of their car commutes and 30 percent of their driving errands with e-bike rides. All you need is a great commuter bag to carry your stuff, and you’re set.
Getting an e-bike can dramatically increase how often you ride, according to a survey of nearly 1,800 e-bike owners in North America. Beforehand, 55 percent of respondents said they rode daily or weekly. After buying an e-bike, that number soared to 91 percent. It makes sense: Even if you’re super fit, you still get tired (likely from training or racing) and remounting your bike can feel like a chore. If you have an e-bike, you can continue riding while giving your knackered legs a bit of a break. You can also go faster, which makes biking for longer trips more attractive, even when you’re pressed for time.
For those who aren’t frequent riders, e-bikes open up a whole new world. While you may not be conditioned to ride 5-10 miles at a time, you can cover those distances easily with an electric assist, which is a great way to build endurance and confidence. That same survey found that 94 percent of non-cyclists rode daily or weekly after getting an e-bike.
Name a type of riding, and there’s an e-bike for that. If you have zero interest in an electric road bike, you may find yourself head over heels for a high-capacity e-cargo bike that can haul 400 pounds of stuff while still cruising at a cool 15 mph. E-bikes are available in fat, cargo, commuter, recreational, hardtail, full-suspension mountain, and even performance road bike styles. For proof, here are a dozen e-bikes we love for every type of cyclist.

  Keyboard and mouse basics
Posted by: fowjw558 - 08-17-2021, 02:41 AM - Forum: Welcomes and Introductions - No Replies

This article is about the introduction of the keyboard mouse PC item.
Using a keyboard
Whenever you use a desktop computer or laptop, you’ll probably use a computer keyboard. The most common kind is called a ‘QWERTY’ keyboard. QWERTY describes the top row of letters on the keyboard.
What a keyboard looks like
A keyboard is for putting information including letters, words and numbers into your computer. You press the individual buttons on the keyboard when you type.
The number keys across the top of the keyboard are also found on the right of the keyboard.
The letter keys are in the centre of the keyboard.
The symbol keys to the right of the letters include symbols such as the question mark and full stop.
The keys that surround the letters, numbers and symbol keys on the left, right and bottom of the keyboard help you to choose where and how you type.
There are several types of keyboards, such as gaming mechanical keyboard, keyboard and so on.
Using the keys
When you open a document or click in a box to type, you will see a vertical flashing line. This is the cursor, it shows you where you are about to start typing on a page or screen.
Pressing the 'shift' key allows you to type capital letters and the symbols at the top of the keys.
The 'shift' keys are on the left and right of the keyboard, with the arrow pointing upwards.
For capital letters, hold down the 'shift' key and hold and type the letter.
For symbols at the top of a number key, press down the symbol key and then type the symbol. You can use the 'shift' key to type any symbol at the top of a key.
The 'caps lock' key allows you to write in capital letters. To turn it on, press it once and type. To turn it off, press it again.
Putting in spaces, moving your cursor and deleting text
The 'space bar' puts a space between words. Press it once to put in a space.
The 'tab' key puts a bigger space between words. Press it once to put in a space.
The 'enter' key moves your cursor down a line.
The 'arrow' keys allow you to move your cursor in all directions on the page or screen - up, down, left and right.
To delete your typing you need to put your cursor to the right of a word. Press the 'backspace' button to delete your word. The cursor will move to the left and delete as it goes.
Using a mouse
There are lots of different styles of computer mouse, but most have a left and a right button.
To hold your mouse, rest your hand over it and put your index finger on the left button and your thumb resting on the side. The cable needs to be pointing towards the computer. The mouse needs to always be in contact with a mouse mat, desk or hard surface.
You use your mouse to move the cursor around the screen. The cursor changes, depending on what you are doing on the computer. As an arrow you use it for moving and selecting things, as a hand for clicking on links when you are on the internet and it becomes an hourglass when you are waiting for the computer to do something.
Single clicking
You single click with the left mouse button to select things. Just quickly left click and then let go of the button.
Double clicking
You double click with the left mouse button to open things, such as a folder. You need to double click quickly, think about the ‘knock, knock’ you do on a door.
Drag and drop
Drag and drop is when you move something from one place to another. 
First select the item with the left mouse button and keep the button pressed down. Then move the mouse and the item on screen will move with the cursor. When you have the cursor and item in the position you want, release the left mouse button.
The item will now be dropped to where the cursor is positioned on the screen.
You use drag and drop to move things around your computer, such as files between folders.
Right button
If you ever accidently click the right mouse button, a list of computer commands will appear. To remove the list just move the mouse and single click the left button.
Laptop trackpad or touchpad
Laptops can have a built in mouse within the keyboard. This is operated by finger touch. This specialised surface is used instead of a mouse and needs only very short finger movements to move the cursor across the display screen.
Improve your computer skills
Why not develop your computer skills - there are courses for beginners and beyond. These range from free online learning through to training, which can lead to qualifications.
While the gaming keyboard mouse industry has almost completed its quest for true gaming perfection, many of today’s gamers still find themselves asking that age-old question – should I choose a wired or wireless gaming mouse?
It’s a question that has plagued many over the last couple of decades, with consumers struggling to decide whether or not the benefits of wireless technology actually outweigh the reduction in gaming performance they sadly lose.
That being said, thanks to huge leaps forward in technology, the gap between wired vs wireless gaming mice has now become much less apparent. Today’s mice come equipped with new technologies that offer Lightspeed connectivity and an almost unlimited amount of battery life – making wireless gaming mice more popular than ever before. Furthermore, wireless mice now bring fantastic gaming performance to the table that really does give their wired alternatives a run for their money.
With the current batch of high-performance gaming mice giving consumers the ultimate headache when deciding which one to choose, we thought we’d whip this article together explaining the differences between wired and wireless gaming mice. We’ll be looking at the main specifications that affect gaming performance, the main differences between the two technologies, and whether or not you should choose wired or wireless for your next gaming mouse purchase.
So, with that in mind, let’s waste no further time and dive straight into it
THE BEST WIRED OR WIRELESS GAMING HEADSETS TO BUY
If you’re shopping for a gaming headset, you have a lot of options. While there are some great ones out there, it’s easy to pay too much, to accidentally purchase a headset that doesn’t work with your desired console or platform, or to get one that’s just uncomfortable. Knowing a thing or two about headphones might aid in your search, but gaming headsets have only gotten more complicated to shop for — especially the wireless ones.

For instance, wireless headsets made for Xbox operate without a dongle via Microsoft’s proprietary wireless protocol. They’ll only work on Xbox consoles or a PC that has one of Microsoft’s Xbox Wireless Adapters plugged in, in most cases. Conversely, if you get a multiplatform wireless headset that includes a 2.4GHz wireless dongle, it’ll likely work on the likes of the PS4, PS5, Nintendo Switch (when plugged into the console’s TV dock), and PC — but not Xbox. It’s best to buy the headset that mentions support for your preferred platform(s) explicitly, or else there’s a good chance you’ll run into some compatibility issues. Of course, you can eliminate most of the guesswork by buying a wired gaming headset instead.

This guide focuses on newer options that you’re more likely to encounter at stores as opposed to older models that, while possibly still being worthy of your money, are often tougher to find affordably and easily online. Also, just to mention it at the top, I have a large-ish head and that factor obviously played a major role in how I judge the comfort of these headsets.

You’ll find a few categories below, including the best multiplatform wireless headsets that are compatible with PC, PS4, PS5, and Nintendo Switch via its dock, the best Xbox wireless gaming headsets, the best PlayStation wireless gaming headsets, and the best wired gaming headsets that support the widest variety of platforms, from console controllers to phones, tablets, and VR headsets that feature a 3.5mm headphone jack.
If you have ever found yourself searching for a new pair of headsets, you have encountered the overwhelming variety of choice that you are nowadays faced with. Over-the-ear, on-the-ear, noise-cancelling, wireless, wired… the market seems to be oversaturated with terms, that needs further clarification.


So, how to choose the best headset?

To start with, there is no such thing as the best headset. Rather, it all depends on your usage and needs. How much time you spend on the phone, what kind of job you do, whether you work in an open office or what type of phone you’re using – all of these factors will influence your choice.


But let’s take one step at a time and focus on how to choose between wired and wireless headsets in the first place. For that purpose, we will need to look at different work styles, as they play a key role in your choice between wired and wireless headsets.

If you spend most of your time at your desk, you are probably what is generally defined as desk worker. You are often on calls with customers, colleagues or other stakeholders. You probably use desk phones most, but Microsoft Teams or Skype for Business are also part of your daily routine. For you, clear audio has the utmost importance – there is no place for questions like “What? Could you repeat, please?”. Perceiving the slightest change in the tone of voice of your caller can make a great difference in your job. You don’t want to worry about your equipment – it should work easily and instantly, allowing you to simply focus on the call and the customer.


If you find this description to be an accurate representation of your workstyle and needs, you will then be satisfied with wired headset.
Wired headsets often offer a higher definition audio quality than wireless headsets, while also minimizing the risk of interferences that can happen with wireless signals. This guarantees perfectly clear audio. At the same time, being plug-and-play, wired headsets can be put in use in no time – avoiding wasting precious seconds in setting up and connecting your device.

But what if you would consider yourself a road warrior instead? You spend most of your time on-the-go – in your car, on public transport – running around to different meetings in the city. Being able to make use of the time you have in between meetings is of extreme importance to you. That is why you need a device that enables you to easily take calls from both, your PC and mobile, in the office and on-the-road. You need to be able to move quickly between working situations, while still hearing and being heard clearly.
Or maybe you’re a corridor worker. You spend most of your time working in the office, both at your desk and in meetings. You walk a lot around the office building, and you need a device that allows you to talk while freely roaming office corridors.
In both cases, a wireless headset would be more suitable for you.

Office headset give you the freedom to move as you like, walking or even running around without the risk of getting tangled in any cords – and still being able to hear and be heard perfectly. And with most devices nowadays being Bluetooth-enabled, you will be able to easily connect your wireless headset to both, your mobile and PC.

  Insulation parts
Posted by: fowjw558 - 08-17-2021, 02:38 AM - Forum: Welcomes and Introductions - No Replies

As a professional manufacturer of insulation parts. Our factory is equipped with 3,4 and 5-axis machining on a range of CNC Milling machines. One of our advantages is that we are not only offering insulation tube or insulation rod, but also secondary machining service for our customers. Therefore, we can help on cost down and shortening lead time. 
Learn about the following insulation parts:
Epoxy Glass Tube
Epoxy Glass Tubes are highly economical insulating tubes that offer a combination of excellent mechanical strength and good electrical performance. Like our Epoxy Glass Rods, our Epoxy Glass Tube is capable of withstanding continuous temperatures up to 130oC (though other grades of material, such as our Isoval Tube, with higher temperature ratings are also available upon request).
The combination of electrical performance and mechanical strength offered by our epoxy glass tube allows them to often be utilised in the manufacture of insulating bushings as well as insulating sleeves. Yellow in colour, our Epoxy Glass Tube can be machined to tight tolerances and thin wall thicknesses.

Epoxy Fiberglass Rod
12 foot long epoxy fiberglass rod 11 16 diameter is made of high strength aramid fiber and glass fiber, impregnated with epoxy resin by pultruding under high temperature. It has ultra-high strength, excellent wear resistance, acid and alkaline resistance, corrosion resistance and other excellent high temperature performance characteristics. It is suitable for electrolytic aluminum plant, steel works, high temperature metallurgical equipment, ultra-high voltage electrical equipment, aerospace and aerospace fields, transformers, capacitors, reactors, high voltage switches and other high voltage electrical appliances.

CNC machining is a term commonly used in manufacturing and industrial applications. But exactly what is CNC? And what is a CNC machine?
CNC 101: The term CNC stands for 'computer numerical control', and the CNC machining definition is that it is a subtractive manufacturing process which typically employs computerized controls and machine tools to remove layers of material from a stock piece—known as the blank or workpiece—and produces a custom-designed part. This process is suitable for a wide range of materials, including metals, plastics, wood, glass, foam, and composites, and finds application in a variety of industries, such as large CNC machining, machining of parts and prototypes for telecommunications, and CNC machining parts, which require tighter tolerances than other industries. Note there is a difference between the CNC machining definition and the CNC machine definition- one is a process and the other is a machine. A CNC machine is a programmable machine that is capable of autonomously performing the operations of CNC machining.
Subtractive manufacturing processes, such as CNC machining, are often presented in contrast to additive manufacturing processes, such as 3D printing, or formative manufacturing processes, such as liquid injection molding. While subtractive processes remove layers of material from the workpiece to produce custom shapes and designs, additive processes assemble layers of material to produce the desired form and formative processes deform and displace stock material into the desired shape. The automated nature of CNC machining enables the production of high precision and high accuracy, simple parts and cost-effectiveness when fulfilling one-off and medium-volume production runs. However, while CNC machining demonstrates certain advantages over other manufacturing processes, the degree of complexity and intricacy attainable for part design and the cost-effectiveness of producing complex parts is limited.
While each type of manufacturing process has its advantages and disadvantages, this article focuses on the CNC machining process, outlining the basics of the process, and the various components and tooling of the CNC machine (sometimes incorrectly known as a C and C machine). Additionally, this article explores various mechanical CNC machining operations and presents alternatives to the CNC machining process.
Are you between jobs right now or an employer looking to hire? We've got you covered with our in-depth collections of resources for industrial job seekers and employers looking to fill roles. If you have an open position, you can also fill out our form for a chance to have it featured in the Thomas Monthly Update newsletter. 
Overview of CNC Machining Process
Evolving from the numerical control (NC) machining process which utilized punched tape cards, CNC machining is a manufacturing process which utilizes computerized controls to operate and manipulate machine and cutting tools to shape stock material—e.g., metal, plastic, wood, foam, composite, etc.—into custom parts and designs. While the CNC machining process offers various capabilities and operations, the fundamental principles of the process remain largely the same throughout all of them. The basic CNC machining process includes the following stages:

  • Designing the CAD model

  • Converting the CAD file to a CNC program

  • Preparing the CNC machine

  • Executing the machining operation
CAD Model Design
The CNC machining process begins with the creation of a 2D vector or 3D solid part CAD design either in-house or by a CAD/CAM design service company. Computer-aided design (CAD) software allows designers and manufacturers to produce a model or rendering of their parts and products along with the necessary technical specifications, such as dimensions and geometries, for producing the part or product.
Designs for CNC machined parts are restricted by the capabilities (or inabilities) of the CNC machine and tooling. For example, most CNC machine tooling is cylindrical therefore the part geometries possible via the CNC machining process are limited as the tooling creates curved corner sections. Additionally, the properties of the material being machined, tooling design, and workholding capabilities of the machine further restrict the design possibilities, such as the minimum part thicknesses, maximum part size, and inclusion and complexity of internal cavities and features.
Once the CAD design is completed, the designer exports it to a CNC-compatible file format, such as STEP or IGES.
CNC Machining Tolerances Tables
When specifying parts to a machine shop, it's important to include any necessary tolerances. Though CNC machines are very accurate, they still leave some slight variation between duplicates of the same part, generally around + or - .005 in (.127 mm), which is roughly twice the width of a human hair. To save on costs, buyers should only specify tolerances in areas of the part that will need to be especially accurate because they will come into contact with other parts. While there are standard tolerances for different levels of machining (as shown in the tables below), not all tolerances are equal. If, for example, a part absolutely cannot be larger than the measurement, it might have a specified tolerance of +0.0/-0.5 to show it can be slightly smaller, but no larger in that area.

  Does the colour of the mug influence the taste of the coffee?
Posted by: fowjw558 - 08-17-2021, 02:37 AM - Forum: Welcomes and Introductions - No Replies

In experiment 1, the white travel mug enhanced the rated “intensity” of the coffee flavour relative to the transparent mug. However, given slight physical differences in the mugs used, a second experiment was conducted using identical glass mugs with coloured sleeves. Once again, the colour of the mug was shown to influence participants’ rating of the coffee. In particular, the coffee was rated as less sweet in the white mug as compared to the transparent and blue mugs.
Both experiments demonstrate that the colour of the mug affects people’s ratings of a hot beverage. Given that ratings associated with the transparent glass mug were not significantly different from those associated with the blue mug in either experiment, an explanation in terms of simultaneous contrast can be ruled out. However, it is possible that colour contrast between the mug and the coffee may have affected the perceived intensity/sweetness of the coffee. That is, the white mug may have influenced the perceived brownness of the coffee and this, in turn, may have influenced the perceived intensity (and sweetness) of the coffee. These results support the view that the colour of the mug should be considered by those serving coffee as it can influence the consumer’s multisensory coffee drinking experience. These results add to a large and growing body of research highlighting the influence of product-extrinsic colour on the multisensory perception of food and drink.

In Australia alone, around a billion cups of coffee are consumed in cafés, restaurants and other outlets each and every year. Even Britain, a nation famous for its fondness for tea, has, in recent years, seen a dramatic rise in its coffee consumption, with an estimated 70 million cups drunk each day. Given the economic incentive to keep consumers drinking coffee, café owners, restaurateurs, crockery designers and manufacturers ought, presumably, to be interested in anything that can help to enhance the multisensory coffee drinking experience for their clientele cf.
The idea behind experiment 1 came about serendipitously. During a conversation between the first author (GV) and a barista, the latter reported that when coffee is consumed from a white, ceramic mug, it tastes more bitter than when drunk from a clear, glass mug instead; note that these two mug types are amongst the most commonly used vessels to serve coffee in Australian cafés and restaurants. In the present study, we therefore sought to establish the validity of this claim which, to our knowledge, has not been described previously. Indeed, as recently highlighted by Spence and Wan, there is a paucity of research on the psychological impact of the receptacles that we use to drink from.
The notion that the colour of the receptacle/plateware can impact taste/flavour perception might relate to Piqueras-Fiszman et al.’s research putatively showing that colour contrast resulted in a red, strawberry-flavoured mousse presented on a white plate being rated as 10% sweeter and 15% more flavourful than when exactly the same food was presented on a black plate, see for an extension of this work; see for an explicit attempt to evaluate the colour contrast account. While contrast represents one plausible explanation for such results, it is important to note that there are also several other possible mechanisms (e.g., priming) that may explain the influence of product-extrinsic colour on taste/flavour ratings. Taking the principal of colour contrast one stage further, and given the conversation with the barista, it was proposed that brown may be associated with bitterness (or, perhaps, is negatively associated with sweetness). If taste were to be affected crossmodally by colour contrast, then coffee that is tasted from a white coffee mug should be rated as somewhat more bitter than exactly the same coffee when consumed from a transparent mug instead.
It is possible that another contrast mechanism (i.e., simultaneous contrast) might affect the perception of taste . Here, if light, opaque, milky brown coffee were to be associated with bitterness, then a light blue mug/surrounding should intensify the brown of the coffee because blue is brown’s complementary colour . This, in turn, would be expected to elevate ratings of bitterness relative to the same coffee when served in a transparent mug. Some famous examples of the use of simultaneous contrast are Heinz’s™ use of a greenish-blue can to set off the red-orange colour of their beans and sauce and Cadbury’s™ use of purple packaging to enhance the colour of their chocolate.
Although many studies have been published on colour-flavour interactions over the years, see  for a review, very little has been published to date specifically looking at crossmodal influences on the perception of coffee. This absence is surprising given, as we saw above, how many cups of coffee are drunk every day. In terms of the limited research that has been conducted specifically in this area, Favre and November offered 200 people coffee from four different jars, i.e., brown, red, blue and yellow. Seventy-three percent of the participants reported that the coffee served from the brown container was too strong, whereas 80% of women felt that the coffee served from the red receptacle had a richer, fuller aroma. The blue jar suggested a milder aroma to most and the coffee in the yellow container was rated as coming from a weaker blend.
Meanwhile, Guéguen and Jacob had 120 people drink coffee from four different coloured cups (blue, green, yellow and red). The participants had to indicate which coffee was the warmest (in terms of its temperature). Thirty-eight percent of the participants reported that the coffee served from the red cup was the warmest, followed by yellow (28.3%), green (20.0%) and, finally, blue (13.3%). Note that these differences were statistically significant. In summary, the colour of the cup can be added to the list of factors that have now been demonstrated to influence various aspects of the coffee drinking experience. This list also includes whether or not the coffee had an eco-friendly origin and any branding cues.
Based on previous work and anecdotal evidence, we explored the impact of the colour of a receptacle on people’s coffee drinking experience. If extrinsic cues influence a consumer’s experience of coffee, and if taste is affected by contrast effects, coffee tasted/drunk from a white mini mug should be rated as more bitter than from a clear mug instead. Given Piqueras-Fiszman et al.’s  and Stewart and Goss’work with strawberry mousse and cheesecake, respectively, we thought that it is possible that the brown-bitter association might be enhanced by colour contrast. However, and with regard to the colour of coffee and the colour of the immediate surroundings against which it is presented, simultaneous contrast might be at work. Specifically, the brown of the coffee may be intensified if the coffee is served from a light blue mug. It should be noted that factors other than contrast effects can influence perception. For example, the cup in which the coffee is served may affect us as a function of our perception of the general properties of the cup (i.e., cheap vs. expensive , flimsy vs. strong). We have attempted to control these potentially confounding variables in the present study. That said, and to borrow from Piqueras-Fiszman et al., if the colour of the mug affects the way in which people perceive the colour of the coffee, and the colour of the coffee affects the perception of flavour, then the colour of the mug (and any contrast effect that it elicits) would be expected to influence the perceived properties of the coffee (e.g., bitterness).
The travel mug type exerted a significant influence on participants’ ratings of the perceived intensity of the café latté, F(2,15) = 4.78, p = .025 (see Figure  Bonferroni-corrected post hoc tests revealed that the café latté was rated as significantly more intense (p = .026) when served from the white, ceramic mug than when served from the clear, glass mug. None of the other comparisons reached statistical significance. The mug type failed to exert any influence on participants’ ratings of the other attributes of the café latté (see Table .
The white mug enhanced the perceived “intensity” of the coffee flavour relative to the transparent mug. Our hypothesis was that a crossmodal association between brown and bitter exists and that bitterness, and possibly other attributes, would be enhanced by the colour contrast. Although there was no simultaneous contrast effect (i.e., coffee surrounded by its complementary colour was not rated as any more bitter than the coffee presented in either the clear or white mug), it is possible that colour contrast influenced the intensity of the coffee flavour in experiment 1.
The mug type exerted a significant influence on participants’ ratings of the perceived sweetness of the café latté, F(2,33) = 3.57, p = .040 (see Figure. Bonferroni-corrected post hoc tests established that the drink was rated as significantly less sweet (p = .041) when served from the white mug relative to the see-through, glass mug or the blue mug. None of the other comparisons reached statistical significance. The mug type failed to exert any influence on participants’ ratings of the other attributes of the café latté (see Table.

Crossmodal influences refer to the effects that information from one sensory modality can have on the perception of information from another. The main issue explored in this study was whether consumers’ perception of a warm café latté would be influenced by the colour (transparent, white or blue) of the mug from which it was served and consumed. Our results clearly demonstrate that the colour of the mug does influence the perceived taste/flavour of coffee.
In the two experiments presented here, it was hypothesised that a crossmodal association between brown and bitter exists and that bitterness, and possibly other attributes, would be enhanced by the colour contrast. In experiment 1, the white mug was found to enhance the perceived “intensity” of the coffee’s flavour relative to the transparent mug. However, given slight differences in the mugs used in experiment 1, we decided to conduct a follow-up study with identical mugs. Experiment 2 revealed that the white mug diminished the “sweetness” of the coffee flavour relative to the transparent and blue mugs.
Given that ratings associated with the transparent glass mug were not significantly different from those associated with the light blue mug in either experiment, it seems as though simultaneous contrast cannot be used to explain the observed results. However, it is possible that colour contrast influenced the intensity/sweetness of the coffee’s flavour. That said, an alternative mechanism (i.e., sensation transference) might also be at play in experiment 1  In short, implicit judgments regarding the intensity of the white mug may be transferred to the coffee causing it to be perceived as more intense than the coffee served in the other mugs. Given Favre and November’s  finding that people report coffee served from a brown container to be too strong (i.e., too intense) and our results from experiment 2, it seems unlikely that (1) people would hold an implicit “intensity” judgement for both white and brown colours and (2) ‘sensation transference’ is the mechanism at work here. Similar to an argument made by Piqueras-Fiszman et al., it seems more plausible to suggest that the white background of the coffee mug may have influenced the perceived brownness of the coffee and that this, in turn, was what influenced the perceived intensity (and sweetness) of the coffee. As we replicate the basic finding that the colour of the mug makes a difference, the correspondence between the visual appearance of the mug and aspects of the flavour suggests that colour contrast mechanisms may be at work here.
Two findings are worth highlighting here: (1) that there is a general trend in experiment 2 towards an increased “intensity” rating (i.e., ratings of intensity were greater for coffee served in the white mug), but this effect failed to reach significance, and (2) the significant intensity and sweetness results of experiments 1 and 2, respectively, might be connected. Note that consumers, as compared to baristas, appear to blur the distinction between ‘intensity’ and ‘bitterness’. Dijksterhuis has suggested that because of the use of the word ‘strong’ in advertising, consumers often confuse a coffee’s strength or intensity with its ‘bitterness’—in fact, visual inspection of Tables 1 and 2 reveals that there is a trend in bitterness ratings that mirrors intensity ratings that would support such a view. Furthermore, any reduction in the “sweetness” of the coffee when presented from a white mug might also be expected to signify an increase in perceived bitterness (or strength). As mentioned above, Koch and Koch  also found that brown, amongst other colours, was negatively associated with sweetness.
Marketers such as Favre and November have reported an effect of jar colour on perceived coffee aroma. Coffee served in a blue jar was more often judged as having a milder aroma than the same coffee when presented in jars of other colours. By contrast, we observed no effect of blue on aroma or any of the other attributes. Favre and November  seem to have documented a simultaneous contrast effect for “mildness” which might be considered to lie at the opposite end of an “intensity” rating scale. Elsewhere, researchers have demonstrated that the colour of plastic vending cups influences people’s perception of hot chocolate, such that orange (with a white interior) enhanced the chocolate flavour, as did dark-cream coloured cups which also enhanced sweetness and aroma . Although our findings differ in their details from those of Piqueras-Fiszman and Spence , they nevertheless concur at a more general level in demonstrating the importance of the colour of the container/plateware on the consumer’s experience of a variety of food and drink products, see also. Our results also help to address the relative paucity of literature on the influence of drinking receptacles as recently highlighted by Spence and Wan .

  What is a Filter Press and How Does it Work?
Posted by: fowjw558 - 08-17-2021, 02:35 AM - Forum: Welcomes and Introductions - No Replies

filter press is one of the oldest and most trusted pieces of dewatering equipment. It’s used for wastewater treatment across a variety of industries and applications. A filter press works by separating out solids from liquids, removing impurities, and suspended solids from industrial wastewater. This allows plant managers to easily handle and dispose of waste while returning clean water to their systems.
Filter presses separate liquids and solids. Specifically, the filter press separates the liquids and solids using pressure filtration across a filter media. Afterward, the slurry is pumped into the filter press and then dewaters under pressure.
Basically, the concentrate filter press design is based on the dewatering volume and type of slurry. ChemREADY is an expert in liquid and solid separation and offers a wide range of filter press types and capacities to suit specific application needs for trouble-free, economical dewatering.
The origin of the filter press dates to around the mid-19th century in the United Kingdom, where a rudimentary form of the press was used to obtain vegetable oil from seeds. However, it wasn’t until major developments in the mid-20th century that engineers were able to develop the world’s first automatic horizontal-type filter press.
It’s this long history of advancements that’s allowed the filter presses of today to achieve significantly lower energy and maintenance costs compared to their belt press and centrifuge counterparts. In fact, the total operating filtration cost for a filter press can easily be 1/6 the cost of what it would be for a belt press or centrifuge.
While there are many different styles of modern filter presses, the plate and frame filter press are one of the oldest and most tested types of dewatering equipment available. You can read more on this type of filter press, along with a more detailed comparison between different types of dewatering equipment, in our Water Facts blog on How Industrial Wastewater Pretreatment Works.
Filter presses are especially useful as the leftover solids are cheaper and easier to move than the entire slurry. With the clean water that filter presses return, plant managers can discharge that to their local municipalities, watersheds or use the water in their own closed-loop systems, creating highly efficient processes.
Without a filter press or similar pieces of dewatering equipment, a settling pond is often the first option for water treatment. Not only do ponds require a large amount of real estate to use, but they also lose their ability to clean water over time as the solids that you remove build up in the pond water. This gives ponds an unfavorable long-term ROI as dirty water will eventually start coming back into your process unless you dredge the pond or make a new pond. At ChemREADY, we advise the use of a filter press and other dewatering equipment over a pond in most applications.
During the fill cycle, the slurry pumps into the filter press and distributes evenly during the fill cycle. Solids build up on the filter cloth, forming the filter cake in the void volume of the plate. The filtrate, or clean water, exits the filter plates through the ports and discharges clean water out the side of the plates.
Filter presses are a pressure filtration method. As the filter press feed pump builds pressure, the solids build within the chambers until they are completely full of solids. This forms the cake. The filter cakes release when the plates are full, and the cycle is complete. Also, many higher capacity filter presses use fast action automatic plate shifters which speeding cycle time. Matec specifically designs their filter presses for fully automatic, 24-hour operation in a harsh environment such as mines or chemical manufacturing plants for wastewater treatment.
While the various styles of filter presses work differently, they all operate under similar principles. Slurries of water mixed with solids are pumped into the press by using a feeding pump. Once inside the press, pressure – often from a centrifugal pump or similar device – pushes the slurry through chambers made of filter plates. This removes impurities from the water as “filter cakes” of solids build up on the machine’s filters.
Once the chambers of a filter press are full, its filtration cycle is complete, and the machine releases the filter cakes. These cakes are easily removed, allowing you to filter your water at high efficiencies. In filter presses, fast action automatic plate shifters may be used to help speed up cake removal and cycle time. In harsher environments where continuous operation is required – like in mining processes or chemical manufacturing plants – a fully automatic filter press design is needed to handle the 24-hour workloads.
To get the best performance out of your filter press, the cloth of the filter should be specifically designed for your application and the types of solids that you are filtering.
The following can also be customized to fit your individual needs:
In addition to these, you can use additional systems such as cloth washing systems, drip trays, and cake shields to further increase filter press performance and functionality. Ultimately, each filter press should be designed based on the expected volume and type of slurry that it will be handling.
Since filter presses work using pressure, equipment that increase pressure through the means of high-pressure technology are great for optimizing your dry tailings filter press system. That’s the secret to success for Matec® filter presses, which use pressures of 21 to 30 bar to handle even the most difficult and hard to treat slurries, no matter the sector or application.
Filter presses can be built in a wide range of sizes, from small, lab-scale presses, to those with much larger capacities, such as those with 2000×2000 mm plates.
While filter presses are great pieces of dewatering equipment, they are best used on a slurry made up of about 50-60 percent solids. Lower solids concentration requires running the water through a clarifier first.
Clarifiers are best described as large settling tanks, preferably used in the initial dewatering phase. Here, water can enter at a much lower solids concentration, typically around 5-10 percent solids. Using gravity and polymers, clarifiers cause solids to build up at the bottom of the tank, where they can be discharged as sludge.
The two main types of clarifiers are the horizontal rake style clarifier and the vertical deep cone clarifier. Vertical deep cone clarifiers use the principle of static decantation for a natural precipitation of solid material, while horizontal rake style clarifiers use a rake mechanism that stirs the sludge through rotation. Determining which type of clarifier is best for you depends on your clarifying needs, driven by maintenance costs, material types and solids requirements. You can read more on the two different types of clarifiers in our Water Facts blog, Deep Cone vs. Rake Style Clarifiers.
When used in combination with each other, a clarifier and chemical filter press can recover 90-95 percent of your water as clean water. The remaining water will discharge with the solids from the filter press.
Here at ChemREADY, our team of water treatment experts can help bring your dewatering efforts together with a total water treatment that optimizes your systems. We can analyze your water from a chemical perspective to find the right flocculants, coagulants, and pH balancers that we can used to treat your water before it goes through mechanical separation. This helps to optimize the performance of your clarifiers and filter presses, giving you a better and more efficient total water treatment.
Apart from our chemical products, we also can help get you setup with the best dewatering devices, including the Matec filter press.

The Filter Press is one of the oldest filtration technologies still in use today. It was first developed in the mid 1800’s. Unlike vacuum filters, which operate continually, the Filter Press and many other pressure filters run in batches. After a batch of slurry has run through the filter, and the filtrate drained out, it must shut down, open the filter pack, and discharge the solid cake.
The components of a featured filter press include the frame or skeleton and the filter pack. The filter pack consists of plates, sometimes frames, and filter media.
Stationary Head- The side of the frame without the closure system has a head that aligns with the filter pack. It is also known as the fixed head. It has a feed hole for the slurry to enter and drain hole for filtrate to exit.
Follower Head- The hydraulic ram pushes the follower head, or thrust head against the filter pack. There are no feed or drain holes on this head.
Closure System- A hydraulic ram is used to press the plates together and hold the filter together during operation. It creates a positive seal and prevents leaks.
Sidebars- The smelting washing filter press plates rest on sidebars to keep alignment and bear weight.
Pump- Necessary to create the pressure which drives the process, it is usually a positive displacement pump or a centrifugal feed pump.
Extra Features- Newer models can include additional components like plate shifters, spray bars, and automatic cake dischargers.
While cotton was the main filter media, in the 1960’s synthetic fibers created better performing and longer lasting press cloths. National Filter Media  has a wide variety of fibers, and weave types. Please contact Shane in the link on the Navbar if you would like to ensure that the cloth your filter  uses is the best one for your application.
Here is a list of configurations for Media.
Drape over cloth- Twice the length of a plate, a Drape Over Cloth sits on top of the plate and lays down each side. It can be held in place by small nubs, or “dog ears”.
Drape over paper- If cake has a tendency to blind filter media after one batch, a filter paper can be draped on top of the cloth. When the Filter Press opens to discharge, the paper is thrown out with the cake.
Duplex cloth- Two separate cloths, each the size of a plate’s single face, are sewn to a gusset that covers the feed hole that runs through a plate. The top and side edges of the cloth either have grommets or Velcro to secure both side of the cloth to the plate.
CGR Cloth- This duplex cloth is shaped to fit in the groove of a CGR Plate. There is a rope sewn into the cloth’s border that gets caulked into each side of the plate.
As filtrate passes through the filter cloth it collects on the plate panel and drains into outlet holes on the corner(s) of the panel.  The outlet holes have a channel that goes into the adjacent corner eye.  The channel runs between the packing surfaces.  Another function of the system is to allow the cake to be dried “blown down” by compressed air.  The manifold piping at the end of the press can be valved to let air into the even numbered plates pushing the liquid thru the cloth/cake/cloth out the odd numbered plates. Sometimes particles of precoat and bodyfeed pass through the filter cloth and become trapped within the drainage channels plugging or partially blocking them.    It can be easy to overlook, since you can’t see into the channels unaided.
The plug likely occurs after a filter cloth tear or if the filter media is too permeable for the precoat and body feed used. The best time to check is when you notice a chamber has not formed a dry, firm cake as it usually does. If some chambers in the filter pack form great cakes and others form wet partial cakes, this could indicate which plates are plugged.
