What Are the Different Types of Light Bulb Fittings, Caps and Bases? |

The part of the oven lamp or light bulb that connects into the light fitting is generally known either as the cap or base. Caps provide the electrical contact to conduct electricity to the light bulb but it also helps to secure the light bulb into its fitting.
There are a vast variety of caps and bases that exist in order to help make sure that only the correct type of lamp is used in any given fitting. This section shows many of the most popular fittings.
Named after the pioneering inventor Thomas Edison, the Edison screw oven lamp or ES lamp fitting is used worldwide in a vast range of applications. The most popular ES or E27 fitting is 27mm diameter and is widely used in UK and Europe. This cap is the standard 27mm diameter screw cap for UK 240V light bulbs – not to be confused with E26, which is a 26mm size and is designed for the 120V US market.
The G9 Oven lamp is specifically used for 240V capsule light bulbs. The light bulb can be identified by measuring the distance between the center points of the pins. The distance of a G9 measures 9mm.
LED Capsule Bulbs are now also available as an energy-efficient alternative to light bulbs. The fitments on LED capsules are exactly the same as those on halogen capsules, so if you’re replacing your current light bulbs with LED light bulbs and your fitting accepts one of the standard types listed here, you should be able to install them without an issue.
Different light bulbs are designed for different needs, environments, and situations. If you need a bulb that will last a long time, save you money and deliver bright light, then an LED light bulb with a high lumen output is best for you. If you want a light bulb that is budget-friendly, stylish and great for decorative lighting, then a candle-shaped halogen bulb with a low colour temperature is what you need.
UNDERSTANDING LIGHT BULB CAP TYPES AND BASE FITTINGS
Choosing the correct cap type or base fitting is the most important step when it comes to finding the right light bulb. The cap type or base fitting both conducts electricity to the light bulb and secures it into the fixture. Buying a bulb with the wrong Oven lamp holder simply means your lamp will not fit into the fixture – so it’s incredibly important you get it right.
The first letter of the code tells you the base or cap type of the bulb - such as a Bayonet Cap or Edison Screw Base.
The numbers reveal the diameter of the base, or the distance between the pins. This is listed in millimeters.
Some codes will also have additional letters after the numbers. This shows the number of pins or contacts the base has – such as ‘s’ for single, or ‘d’ for double.
So for example, the most common Bayonet Cap base fitting is listed as a B22d fitting. The ‘B’ stands for Bayonet Collar, while the ‘22’ means the base is 22mm in diameter. The ‘d’ at the end of the code means the base has two pins.
Candlelight bulbs feature a design based off the flame of a candle. This attractive ‘flame’ shape naturally gives them a decorative, elegant and vintage look perfect for ornamental lighting in hotels, restaurants and bars. As such, candle bulbs are most commonly used as decorative light bulbs in chandeliers, wall lights and exposed fixtures. Candle light bulbs are generally fitted with an E27 Edison screw base, E14 Oven lamp holder or B22 bayonet cap.
The Edison screw base is another of the most commonly seen base fittings in the UK. As their name suggests, Edison screw bulbs simply screw into the socket of a light fixture.
The most frequently seen size of the Edison screw is the E27 – a fitting that measures 27mm in diameter across its base. Other sizes of Edison screw are available, such as the E17, E26 and E39, but the E27 is the most commonly used in the UK and Europe.
E27s are available in a wide range of wattages and are used for a variety of applications.
Capsule bulbs sometimes called capsule lamps, use a push-fit base. Rather than being screwed or twisted into the fitting, these capsules have two pins in the base that allows them to be pushed into a fixture.
These small capsules are named and categorised by the distance between their two connecting pins. The G4 is one of the most frequently used bases for capsule lamps, and has pins that are 4mm apart. The G9 Oven lamp holder is also used for capsule bulbs, and features pins measuring 9mm apart.

Introduction to Pressure Seal valves |

Introduction to Pressure Seal valves
Pressure seal construction is adopted for Valves for high pressure service, typically in excess of above 170 bar. The
unique feature about the pressure seal Bonnet is that the body-Bonnet joints seals improves as the internal pressure in the
Valve increases, compared to other constructions where the increase in internal pressure tends to create leaks in the body-
Bonnet joint.
The higher the internal pressure, the greater the sealing force. Easy dismantling is made possible by dropping the
Bonnet assembly into the body cavity and driving out the four-segmental thrust rings by means of a push pin.
Relying on fairly simple design principles, pressure seal
valves have proven their capability to handle increasingly demanding fossil and combined-cycle steam isolation
applications, as designers continue to push boiler, HRSG, and piping system pressure/temperature envelopes. Pressure seal
Valves are typically available in size ranges from 2 inches to 24 inches and ASME B16.34 pressure classes from #600 to #2500,
although some manufacturers can accommodate the need for larger diameters and higher ratings for special applications.
Pressure seal gate valves are
available in many material qualities such as A105 forged and Gr.WCB cast, alloy F22 forged and Gr.WC9 cast; F11 forged and
Gr.WC6 cast, austenitic stainless F316 forged and Gr.CF8M cast; for over 500°C, F316H forged and suitable austenitic cast
grades.
The pressure seal design concept can be traced back to the mid-1900s, when, faced with ever increasing pressures and
temperatures (primarily in power applications), Valve manufacturers began designing alternatives to the traditional bolted-
Bonnet approach to sealing the body/Bonnet joint. Along with providing a higher level of pressure boundary sealing integrity,
many of the pressure seal globe valves
design weighed significantly less than their bolted Bonnet Valve counterparts.
Bolted Bonnets vs. Pressure Seals
To better understand the pressure seal design concept, let's contrast the body-to-Bonnet sealing mechanism between
bolted Bonnets and pressure seals. FIG. 1 depicts the typical Bolted Bonnet valve. The body flange and Bonnet flange are
joined by studs and nuts, with a gasket of suitable design/material inserted between the flange faces to facilitate sealing.
Studs/nuts/bolts are tightened to prescribed torques in a pattern defined by the manufacturer to affect optimal sealing.
However, as system pressure increases, the potential for leakage through the body/Bonnet joint also increases.
Pressure Seal Gaskets
One of the primary components involved in sealing the pressure seal Valve is the gasket itself. Early pressure seal
gaskets were manufactured from iron or soft steel. These gaskets were subsequently silver-plated to take advantage of the
softer plating material's ability to provide a tighter seal. Due to the pressure applied during the Valve's
hydrotest, a set (or deformation of the gasket profile) between the Bonnet and gasket was taken. Because of the inherent
Bonnet take-up bolt and pressure seal joint elasticity, the potential for the Bonnet to move and break that set when
subjected to system pressure increases/ decreases existed, with body/Bonnet joint leakage the result.
This problem could be effectively negated by utilizing the practice of "hot torquing" the Bonnet take-up bolts
after system pressure and temperature equalization, but it required owner/user maintenance personnel to do so after plant
startup. If this practice was not adhered to, the potential for leakage through the body/Bonnet joint existed, which could
damage the pressure seal gasket, the Bonnet and/or the I.D. of the Valve body, as well as creating compounding problems and
inefficiencies that the steam leakage could have on plant operations. As a result, Valve designers took several steps to
address this problem.
Although many manufacturers still recommend hot torquing, the potential for leakage when this is not done is greatly
diminished. The seating surfaces in pressure seal Valves, as in many power plant Valves, are subjected to, comparatively
speaking, very high seating loads. Seat integrity is maintained as a function of tight machining tolerances on component
parts, means of providing the requisite torque to open/close as a function of gears or actuation, and selection/ application
of proper materials for seating surfaces.
Cobalt, nickel, and iron-based hardfacing alloys are utilized for optimal wear resistance of the wedge/disc and seat ring
seating surfaces. Most commonly used are the CoCr-A (e.g., Stellite) materials. These materials are applied with a variety of
processes, including shielded metal arc, gas metal arc, gas tungsten arc, and plasma (transferred) arc. Many pressure seal
Globe Valves are designed having integral hardfaced seats, while the
Gate Valves and
Check Valves typically have hardfaced seat rings that are welded into the Valve body.
Both butterfly valves and
ball valves offer unique benefits, so choosing between them in
certain processes isn't a hard choice. It can be problematic when a process requires valve characteristics that both
valves have. We need a deeper understanding of the butterfly valve vs ball valve in order to pick the correct valve.
Teflon is a polymer compound formed by the polymerization of tetrafluoroethylene with excellent chemical stability,
corrosion resistance, sealing, high lubrication and non-viscosity, electrical insulation and good aging resistance for media
such as strong acid, strong alkali, strong oxidant. Its operating temperature is -200 ~ 180℃, poor fluidity, large thermal
expansion. Teflon lined valves ensures extremely high
chemical resistance and longevity, can be widely used in corrosive applications in the chemical, electric machinery,
harmaceutical, petrochemical, fertilizer, pulp and paper, and metallurgical industries.

GOLF CART OR UTV? (WHICH IS RIGHT FOR YOU & HOW TO CHOOSE) |

GOLF CART OR UTV? (WHICH IS RIGHT FOR YOU & HOW TO CHOOSE)
Golf carts and UTV are pleasant means of transportation. Comparing
electric and gas golf carts is common, but you rarely see comparing golf carts with UTV. This is mainly because these two
vehicles can be used for very different purposes. However, some intersections may make people wonder which is better, golf
cart or UTV. We have compiled a guide to help you identify differences and which one better meets your needs. Before you
decide which is the better choice, you need to consider a few things.
1. Speed
The speed will be affected by the power supply mode of your shopping cart or UTV and the modifications made to it. Some
normal golf carts do not run very fast. If UTV has many
functions, it will drag it down, and you may lose some speed. You can use gasoline or electric UTV and golf cart at the same
time, but gasoline will be faster. A gas-driven UTV golf cart is often a
little faster than a gas-driven golf cart.
However, some owners can make some adjustments to their golf cart to get faster speed. There are some golf carts and UTV
that can play very well. Some faster vehicles run at about 25 mph.
Of course, on rough terrain, you will find that you cannot get these numbers, but on flat roads, you will get them. It is
difficult to decide whether a golf cart or UTV is more suitable for you only based on speed. In terms of speed, both can
choose to provide you with very similar numbers.
2. Haulage
There is no doubt that UTV hauls better than off-road golf
cart. In most cases, golf carts are made for hauling golf clubs, some players and their equipment. In addition, golf
carts are not known for being able to move heavy objects.
However, some working golf carts can carry several boxes from one area of the maintenance facility to other areas.
Speaking of UTV, part of their design is to help you drag things. When we talk about traction, we mean how much UTV can
carry, and then traction is how much it can pull.
In terms of traction and traction, UTV has more capabilities than
vintage golf cart. Some utvs can carry or tow thousands of pounds. This is not the case with golf carts. If you use UTV
on the farm and move products around the farm, there is no doubt that UTV will be more suitable. The manufacturer's
recommendations must be checked when towing and towing restrictions are involved. You donnot want to try a project just to
find that your vehicle cannot do what you want to do.
3. Gas/electricity
In the past few years, only golf carts can use gasoline and electricity at the same time. It is a relatively new concept
to see that UTV can also be used in power. Although electricity is cleaner and better for the environment, it is usually not
so powerful. This is partly why UTV is used for natural gas. The new electric UTV began to become quite popular.
Compared with gasoline UTV, they are quiet, which helps
to make them more attractive to those who spend a lot of time on their vehicles. The noise of gasoline UTV cars can start to
wear you a little. This is what makes electric models more popular.
Whether you want gas or electricity will depend on how much you expect from your UTV or cart Trailer. Electric golf cart
is more suitable for people who play a round of golf. Their mobility, speed and functionality enable golfers on the golf
course. The natural gas-driven UTV was not built on the same idea. The way you choose to use your car will determine whether
gas or electric is more suitable for you. If you buy a UTV for power and stability, it is best to go with the gas version.
Human driven sightseeing buses have had a good 100-year run.
Throughout this period the urban consumer product has not changed – a city bus tour you took 100 years ago is pretty much
the same as a bus tour you can take today. All the digital innovations and changes we have brought to market over recent
years have been about retail and distribution, plus some ticket redemption adjustments. Nothing with the product experience
itself (adding Wifi doesn’t count!).

The Best iPhone Cases From Apple To Casetify, Mous To Pipetto
The new Apple iPhone 12 is a gorgeous smartphone. So, you’ll want to keep it that way, with a decent case—read on for a
round-up of the very best Apple iPhone 12 kevlar cases you can buy
right now.
When it comes to phone cases, what’s your favorite style? Folio? Sleeve? Back protector? Or something so slim and smooth
you think there’s nothing there at all. Do you like something bright and solid, or something light but strong and ultra-
protective? How hard are they to slide on and off if you fancy a change? Do they protect the display as well as the back? How
sumptuous do they feel in your hand and how much do they weigh your new iPhone down? Whatever kind of case you prefer,
you’ll find them all here. I’ve been testing iPhone 13 new case
s for looks, fit, effectiveness and design appeal.
Also, there is a new element to cases this year: MagSafe. The name may be familiar from the cool way power cables
connected to previous Mac laptops, but it’s now revived as a wireless charging pad. If you’ve ever used a wireless charging
pad you’ll know that if you put the phone down in the wrong place last thing at night, you’ll wake to find the phone didn’
t charge. MagSafe clamps the iPhone in place magnetically so that danger is gone. But MagSafe has other benefits, too: it
tells your iPhone what you’re connecting to it and it holds an iPhone 8~xsmax
case in place magnetically, so it’s much easier to slip the case on and off.
The iPhone 12 is amazingly good value, but it’s still not a cheap purchase. So, you’ll want to protect it. Even though
the arrival of Ceramic Shield means the front glass is intensely more durable and resistant to being dropped, you may feel it
’s not worth taking any chances. Here are the very best cases offering extra protection (and, therefore, extra peace of
mind).
A suitable Apple Smartwatch is very precious. Not only because of its impressive features, but also because of its
unparalleled style and luxurious price tag. More importantly, Apple Watch is a one-time investment for many people, which is
why ensuring its safety is the top priority. Much like the iPhone, Apple Watch also has countless protective cases, from
subtle to statement, you can have everything. Apple Watch case can
protect your investment and protect you from panic attacks every time something hits your precious smartwatch. Therefore, if
you want to be able to continue to wear your Apple Watch without worrying about damage, you can consider buying a sturdy
smartwatch case.
If you are entrenched in the Apple ecosystem and love listening to music with great over-ear headphones, the AirPods Max
is probably for you. However, they come with a case that resembles, shall we say, some undergarments. A good
Airpods pro&max case is needed if you want to protect your headphones
and don't like the case that was shipped with them. Let's explore the best AirPods Max cases on the market today.
Cigars are hand-rolled fermented tobacco. Compared with ordinary cigarettes, they have less nicotine content, less than
2%. Pure natural tobacco, which contains no chemical substances, has little harm to human body and is welcomed by business
people. In many Western movies, we can see such a plot, the protagonist takes out a cigar from a well-decorated cigar box and
ignites it to smoke. Cigar boxes were first made of high-quality wood. They can also be made of plastics, ox bones, carbon
fibers and other materials.
Cigars are like alcoholic drinks. They do not fade away with time, but become stronger and stronger. A common cigar can
be stored in a suitable environment for more than ten or twenty years, and its price can be doubled several times. The most
suitable conditions for preserving cigars are temperature 18 degrees and humidity 70 degrees. Cigar boxes can isolate cigars
from the outside world and keep them in their best condition. Top-grade wooden cigar boxes are made of cigar or mahogany,
walnut and rosewood, which are exquisite in shape and expensive in price. Carbon fiber cigar boxes were invented relatively late, and only recently began to rise. They are light in weight,
small in size, easy to carry with you, and will not have the problem of moist and moth-like wood. Its shape is streamlined
and can closely fit the cigar inside, saving space to the greatest extent.
If you want to buy a new or used CNC router, you want the machine to solve your manufacturing challenges. We provide
manufacturers of all sizes with cutting-edge technology from all woodworking technologies from world market leaders. We offer
superior wood CNC processing technology and equipment for the highly
efficient production of furniture, interior fittings, construction elements, and millwork, for panel processing, plastics and

What are Defoamers? |

What are Defoamers?
Defoamers are chemical additives that reduce and/or prevent the formation
of foam in industrial process liquids such as paints, inks, adhesives and even construction products. The terms antifoam
agent and defoamer are often used interchangeably, however, antifoam agents more accurately refer to materials that inhibit
the generation and formation of bubbles. Dependent upon the application and performance requirements, they consist of
polydimethylsiloxanes and other silicones, insoluble oils, stearates and glycols, as well as inorganics, such as silicates
and talc.
What is Foam?
Foam is a coarse dispersion of a gas in a liquid, where the volume fraction of gas is greater than that of the liquid.
The bubbles will migrate to the surface, as their density is less than that of the liquid. As the bubbles coalesce and
collect at the air/surface interface, the bubble walls thin and break. Silicone defoamers accelerate the process and break the smaller bubbles as well. Generally, a defoamer is
insoluble in the foaming medium and has surface-active properties. An essential feature of a
polyether defoamer is the ability to spread rapidly on
foamy surfaces.
In industrial processes, foams pose serious problems. They cause defects on surface coatings. They prevent the efficient
filling of containers. Some of the sources of foam formation include:
Inclusion of air through agitation during production, filling, mixing of two-pack systems (often high-viscosity
(epoxies, adhesives);
Air inclusion on the pigment surface, resulting in poor wetting of pigments;
Application: roller, spraying, brushing;
Filtration through a sieve or anything with air on the surface;
Generation/liberation of gases during chemical curing processes; e.g. polyisocyanates;
Introduction of air through substrate wetting (wood coatings, other highly porous substrates).
In the papermaking process, fibers, fillers and some additives are not water-insoluble, so they are easy to accumulate in
an aqueous solution. Moreover between the different materials as far as possible from the incompatibility away, so it is
difficult to get uniform performance and ideal strengthen paper. In order to solve the long fiber in the process of this
problem, the use of polyacrylamide has the following advantages:
to improve the retention rate of fillers, pigments and so on. To reduce the loss of raw materials and
environmental pollution.
to improve the strength of the paper (including dry and wet strength).
to improve the tear resistance and porosity to improve visual and printing performance.
The advantages of using polyacrylamide as a paper dispersant are also manifested in the fact that the product is soluble
in water and forms a high viscosity liquid which promotes good dispersion of papermaking fibers and excellent paper forming
effect at low added levels to improve pulp consistency And the softness of the paper, but also to improve the strength of the
paper performance.
Adipic acid is one of the most commercially important aliphatic
dicarboxylic acids. It is produced on a large scale primarily to supply the nylon 6,6 production chain. Other applications
include the manufacture of coatings, synthetic lubricants, fibers, plastics, plasticizers and polyurethane resins. Adipic
acid production has been predominantly based on cyclohexane and, to a lesser extent, phenol. Shifts in the hydrocarbon market
and growing environmental concerns have resulted in the development of alternative production routes for adipic acid from
renewable resources, such as sugar and fatty acids.
Epoxy propanol (EP), also known as glycidol, is an organic compound used in the manufacture of a range of products, such
as detergents, industrial paints and coatings, and healthcare products. It is primarily manufactured in Japan and, to a much
lesser degree, in the United States. Traditionally, EP is produced by one of two methods: epoxidation of allyl alcohol with
hydrogen peroxide, or the reaction of epichlorohydrin with a caustic
agent. However, allyl alcohol is extremely toxic and epichlorohydrin is made from hydrocarbon feedstocks, such as propylene.
Both methods generate toxic by-products, such as hydrochloric acid, requiring costly purification processes to prevent the
acid residues from entering the environment.

UNDERSTANDING ULTRAVIOLET LED APPLICATIONS AND PRECAUTIONS |

UNDERSTANDING ULTRAVIOLET LED APPLICATIONS AND PRECAUTIONS
Ultraviolet light occurs between the visible and x-ray spectrums. The Ultraviolet wavelength range is specified as 10 nm
to 400 nm; however, many optoelectronic companies also consider wavelengths as high as 430nm to be in the UV range.
Ultraviolet light gets its name due to the violet color it produces in the visible portion of the spectrum although much of
the output of UV light is not visible to the human eye.
UV LEDs have seen tremendous growth over the past several years. This is
not only the result of technological advances in the manufacturing of solid state UV devices, but the ever increasing demand
for environmentally friendly methods of producing UV light which is currently dominated by mercury lamps. The current
offering of UV LED modules in the optoelectronics market consists
of product ranging from approximately 265nm – 420nm with a variety of package styles including through-hole, surface mount
and COB (Chip-On-Board). There are many unique applications for UV LED emitters; however, each is greatly dependent on
wavelength and output power. In general, UV light for LEDs can be broken down into 3 general areas.
The upper UVA type devices have been available since the late 1990s. These LEDs have been traditionally used in
applications such as counterfeit detection or validation (Currency, Driver’s license, Documents etc) and Forensics (Crime
scene investigations) to name a few. The power output requirements for these applications are very low and the actual
wavelengths used are in the 390nm – 420nm range. Lower wavelengths were not available at that time for production use. As a
result of their longevity in the market and the ease of manufacturing, these type LEDs are readily available from a variety
of sources and the least expensive of all UV product. The middle UVA LED
component area has seen the greatest growth over the past several years. The majority of applications in this
wavelength range (approximately 350nm – 390nm) are for UV curing of both commercial and industrial materials such as
adhesives, coatings and inks. LEDs offer significant advantages over traditional curing technologies such as mercury or
fluorescent due to increased efficiency, lower cost of ownership and system miniaturization. The trend to utilizing LEDs for
curing is increasing as the supply chain is continually pushing to adopt LED technology. Although the costs of this
wavelength range is significantly greater than the upper UVA
LED module area, rapid advances in manufacturing as well as increasing volumes are steadily driving down prices.
The lower UVA and upper UVB ranges (approximately 300nm – 350nm) are the most recent introduction to the market place.
These devices offer the potential to be used in a variety of applications including UV curing, biomedical, DNA analysis and
various types of sensing. There is significant overlap in all 3 of the UV spectral ranges; therefore, one must consider not
only what is best for the application, but also what is the most cost-effective solution, since the lower in wavelength,
typically the higher the LED cost. The lower UVB LED and upper UVC
ranges (approximately 250nm – 300nm) is an area that is still very much in its infancy, however, there is great enthusiasm
and demand for this product in air and water purification systems. There are currently only a handful of companies that are
capable of manufacturing UV LEDs in this wavelength range and even a smaller amount that are producing product with
sufficient lifetime, reliability and performance characteristics.
As a result, the costs of devices in the UVC/B range are still very high and can be cost prohibitive in some
applications. The introduction of the first commercial UVC LED based
disinfection system in 2012 has helped to move the market forward to where many companies are now seriously pursing LED based
products. Precautions A common question regarding ultraviolet LEDs is: Do they pose any safety risks? As described
above, there are different levels of UV light. One of the most commonly used and familiar sources for producing UV output is
the black light bulb. This product has been used for decades to produce a glowing or fluorescence affect on specific types of
posters as well as for other applications such as the authentication of paintings and currency.

COPPER CABLE LUGS FOR SPECIAL APPLICATIONS |

COPPER CABLE LUGS FOR SPECIAL APPLICATIONS
A well known problem for every electrician or cable jointer is trying to insert a stranded or fine stranded conductor
into the cable lug connector or cable splice and some wires
cannot be inserted. To avoid this problem renowned manufacturers offer specialist application connectors and cable lugs for
the jointing and termination of LV MV HV cables.
CABLE LUGS, STRANDINGS CONDUCTORS
With these specialist application cable lugs all types of cables can be used – the design and construction of the
copper tubular lugs to be selected is
determined by the cable stranding and conductor type. The cable conductor characteristics of cable types are as classified in
the DIN Standard 57295.
CABLE LUGS FOR FINE VERY FINE STRANDED CONDUCTORS
The above mentioned problem of spliced cables per Class 5 and Class 6 according to DIN 57295 is being avoided when using
Klauke “F” type series cable lugs. These lugs are designed for processing larger cross section conductors in voltage
applications up to the short circuit tested rating of the cable lug.
Compared with standard tubular cable lugs the F type lugs have a larger tube diameter – the cable lugs have a flared
entry which eases cable location into the barrel of the lug. F-type cable lugs and butt connectors conform to the normative
requirements of the EN 13600 standard and are manufactured from electrolytic copper for excellent conductivity.
For processing and crimping solid conductors (Class 1 DIN VDE 57295) the use of tubular cable lugs E-type is recommended
which are also manufactured from electrolytic tin plated copper. Their tube diameter is matched to the conductor size to
guarantee a professional cable crimp.
Especially for adverse environments and for crimping copper conductors stainless steel and nickel tubular cable lugs have
been designed. Aluminum lugs are particularly
acid and corrosion resistant and are typically used in chemical industries in areas exposed to sea water i.e. the earthing of
masts on sailing yachts.
An additional benefit of these cable lugs is the temperature resistance. Consequently these lugs can be used in ambient
temperatures up to 400°C.
At higher temperatures of up to 650°C – common in the construction of furnaces – nickel cable lugs represent the best
solution. Both stainless steel and nickel cable lugs can be used for all common cable types.

Plating
There s no such thing as alchemy—magically changing common chemical elements into rare and valuable ones—but water
plating is possibly the next best thing. The idea is to use electricity to coat a relatively mundane metal, such as copper,
with a thin layer of another, more precious metal, such as gold or silver. Water plating has lots of other uses, besides
making cheap metals look expensive. We can use it to make things rust-resistant, for example, to produce a variety of useful
alloys like brass and bronze, and even to make plastic look like metal. How does this amazing process work? Let s take a
closer look!
Plastic water plating involves passing an electric current
through a solution called an electrolyte. This is done by dipping two terminals called electrodes into the electrolyte and
connecting them into a circuit with a battery or other power supply. The electrodes and electrolyte are made from carefully
chosen elements or compounds. When the electricity flows through the circuit they make, the electrolyte splits up and some of
the metal atoms it contains are deposited in a thin layer on top of one of the electrodes—it becomes electroplated. All
kinds of metals can be plated in this way, including gold, silver, tin, zinc, copper, cadmium, chromium, nickel, platinum,
and lead.
Water plating is very similar to electrolysis (using electricity to split up a chemical solution), which is the reverse
of the process by which batteries produce electric currents. All these things are examples of electrochemistry: chemical
reactions caused by or producing electricity that give scientifically or industrially useful
plastic water plating products.
How does water plating work?
First, you have to choose the right electrodes and electrolyte by figuring out the chemical reaction or reactions you
want to happen when the electric current is switched on. The metal atoms that plate your object come from out of the
electrolyte, so if you want to copper plate something you need an electrolyte made from a solution of a copper salt, while
for gold plating you need a gold-based electrolyte—and so on.
Next, you have to ensure the electronic products shell plastic water plating you want to plate is completely clean. Otherwise, when
metal atoms from the electrolyte are deposited onto it, they won t form a good bond and they may simply rub off again.
Generally, cleaning is done by dipping the electrode into a strong acid or alkaline solution or by (briefly) connecting the
Water plating circuit in reverse. If the electrode is really clean, atoms from the two-color material plating bond to it effectively by joining very strongly onto the outside
edges of its crystalline structure.
Now we re ready for the main part of
two-color material twice molding water plating. We need two electrodes made from different conducting materials, an
electrolyte, and an electricity supply. Generally, one of the electrodes is made from the metal we re trying to plate and the
electrolyte is a solution of a salt of the same metal. So, for example, if we re copper plating some brass, we need a copper
electrode, a brass electrode, and a solution of a copper-based compound such as copper sulfate solution. Metals such as gold
and silver don t easily dissolve so have to be made into solutions using strong and dangerously unpleasant cyanide-based
chemicals. The electrode that will be plated is generally made from a cheaper metal or a nonmetal coated with a conducting
material such as graphite. Either way, it has to conduct electricity or no electric current will flow and no plating will
occur.
How are plastics electroplated?
If you know anything about plastic, you ll spot the obvious problem straightaway:
plastic product molding generally don t conduct electricity.
In theory, that should completely rule out electroplating; in practice, it simply means we have to give our plastic an extra
treatment to make it electrically conducting before we start. There are several different steps involved. First, the
plastic surface treatment has to be scrupulously cleaned to
remove things like dust, dirt, grease, and surface marks. Next, it s etched with acid and treated with a catalyst (a chemical
reaction accelerator) to make sure that a coating will stick to its surface. Then it s dipped in a bath of copper or nickel
(copper is more common) to give it a very thin coating of electrically conducting metal (less than a micron, 1μm, or one
thousandth of a millimeter thick). Once that s done, it can be electroplated just like a metal. Depending on how much wear
and tear the plated part has to withstand, the coating can be anything from about 10–30 microns thick.

Proponents of water filters say the water is cleaner and healthier, with impurities removed and minerals added.
Replace water filter and alkaline water companies also
advertise a laundry list of claims, from improved gastrointestinal health to detoxification and even cancer prevention.
Water filter housings are casings around your filter
cartridge that directs the flow of water. In this article, we will take a look at some of the most frequently asked questions
about our water filter housings.
They come in a wide range of types. Mainly water filter housings are of two types. However, there can be subcategories
based on size, material, and purpose.
RO membrane housings will filter your
water right where you use it. For example, an individual tap or faucet. So the systems cover filters under the sink, filters
attached to your faucets, or filtration pitchers. The housings for POU water systems serve this purpose
Water filter clear housings, especially
whole housing systems, offer a versatile large capacity filtration. Since they are geared towards high flow, they can remove
heavy sediments easily. By installing large water filter housings, you can reduce the number of vessels needed for high-flow
applications. It can also withstand variations in water pressure. The large cartridge capacity will be very helpful for you.
Reverse Osmosis works by using a high pressure RO pump to increase the
pressure on the salt side of the RO and force the water across the semi-permeable RO membrane, leaving almost all (around 95%
to 99%) of dissolved salts behind in the reject stream. The amount of pressure required depends on the salt concentration of
the feed water. The more concentrated the feed water, the more pressure is required to overcome the osmotic pressure.

SUSTAINABLE PACKAGING IN THE BEAUTY INDUSTRY: THE PROS & CONS OF PLASTIC.
Plastic is one of the most polarizing topics in sustainability today, and each year continues to reveal more about its
place in the beauty industry. Sustainability is a constantly evolving conversation and the rate at which
cosmetic plastic bottle is produced, used and disposed of has
long outpaced the research, technology and innovation needed to understand the consequences of our actions, making it quite
challenging to gather data that’s specific to cosmetics. Yet, we do know that the volume of plastic which can accumulate
during the process of making a single product is sometimes staggering - if you make cosmetics products for-profit and are
looking to grow, hardly any brand is exempt from the presence of plastic.
In a roadmap for sustainability released by the United Nations Environment Programme in 2018, the executive summary
reads: The benefits of plastic are undeniable. The material is cheap, lightweight and easy to make. These qualities have led
to a boom in the production of plastic over the past century since the 1950s. We are already unable to cope with the amount
of plastic waste we generate unless we rethink the way we manufacture, use and manage plastics. Ultimately, tackling one of
the biggest challenges of our time will require governments to regulate, businesses to innovate and individuals to act.
Let’s admit that plastic has gathered a bad reputation - you might even say it’s been demonized in some cases. To be
clear, there is no denying that waste is a problem, but to blanket shame plastic without context is to miss an opportunity
for a closer look. If you want to dive deeper into all the factors that contribute to plastic waste, take a look at this
hugely informative and fascinating collaboration from Oxford University and the Global Change Data Lab:
Particularly in 2020, single-use consumption of plastics across multiple industries has seen a massive increase due to
essential sanitary and safety precautions needed to manage the spread of COVID-19. It’s important to note that single-use
plastic lotion bottle is a cornerstone
of essential hygiene measures within the medical industry from masks, gloves, gowns and medical instruments. We doubt that we
will comprehend the waste consequences of single use plastic throughout 2020 for sometime to come.
As a beauty brand this is undeniably a charged conversation to have, as plastic is dotted across our packaging chain and
understanding the trade-offs is key. From health effects, to degradation, to ecosystems impact, plastic could easily be a
whole PhD dissertation, and it is challenging to limit our focus when this material is a global common denominator of modern
consumption. We are attempting to share a simplified perspective on the presence of plastics within the cosmetics industry to
better understand the benefits and pitfalls of this material.
We are interested in the life cycle of plastic packaging in cosmetics - more specifically, the contrast between the
production of plastic, versus the use of plastic, versus the end-of-life for plastic. As PET (Polyethylene Terephthalate) is
the most commonly used plastic in cosmetic packaging and for Josh Rosebrook products, we will be focusing on this material to
exemplify the pros and cons of plastic packaging.
Specializing in life cycle assessment (LCA) and solid waste management, a US independent consulting firm, Franklin
Associates, has conducted multiple research studies on PET across various industries. In a 2009 study on the comparison of
beverage containers (very similar to cosmetic containers), Franklin Associates found that the production of a PET bottle was
far more energy efficient when compared to the production of an aluminum can and glass bottle, respectively. The amount of
energy it took to create a PET bottle was 11 million BTU, vs. 16 million BTU for the aluminium can and 26.6 BTU for the glass
bottle. The CO2 equivalent (think greenhouse gas emissions) was 1,125 for the PET bottle, 2,766 for the aluminum can, and
4,848 for the cosmetic glass bottle. When ranking material
production in relation to energy efficiency, plastic is second right after wood, and aluminum and glass are last. There is
conflicting evidence regarding how the world’s oil production contributes to the manufacturing of plastic.
A large majority of finished cosmetic products housed in plastic are multi-use: they are not disposed of after a single
use and the amount of times they are used according to function can range into several hundred uses. Depending on the size
and type, the product could also be kept in use for several weeks to multiple months. It is interesting to note that to bring
a cosmetic product to market, the formula has to undergo a packaging compatibility test - depending on the ingredients and
the function of the product, plastic might be a necessity to safely protect the formula over time and ensure a safe customer
experience. For example, glass liquid bottle
s intended for use in the shower could be troublesome to manage safely.
With the growing importance of appearance for both men and women, there is a huge demand for cosmetics in today’s
market. However, a manufacturer of specialty cosmetics needs to be able to make an impression on the consumer and ensure that
they try the wonderful product first. Additionally, consumers now look for more than a terrific cosmetic, they want it at a
lower price, and are also eco-conscious. Using tube packaging for specialty cosmetics meets multiple requirements of
manufacturers.
Consumers prefer the convenience that cosmetic tube packaging
provides. While cosmetic squeeze tubes were
originally used for food products such as jams, jellies, ad mayonnaise, they are now being used by cosmetics manufacturers.
Consumers love the convenience of tube packaging that comes with a variety of heads that makes dispensing cosmetics much
easier. Consumers can easily dispense the right amount of cosmetics they need, reducing wasted products.
We offer glass and cosmetic parts for glass bottle
s, informing you of what format or material is most recommended in each case.
Glass bottles for oils and vinegar respond to particular characteristics in shape, color and height that can contribute
to creating brand branding alone. In a company, an exclusive design is a guarantee of sales.
Glass bottles for oils preserve and protect the properties of the oil in order not to spoil its natural conditions,
taking into account that many factors increase the process of oxidation and oil thickening.
Those skilled in the art recommend glass bottles for opaque oils to protect liquid gold from light, although transparent
glass bottles sell the product better. Ultraviolet rays should be prevented from damaging the oil by protecting the bottle in
cardboard containers.
