PE (polyester) Coating
PE
(polyester) coating:Using high molecular polymer as monomer and addition of alkyd, this PE coatingmethod of our color coated aluminum coil is an UV-resistant coating. It can beclassified matt and glossy according to coating gloss. The compact moleculestructure makes paint surface luster and smooth, which assures good printing onthe PE coated aluminum coils surface. With a warranty of 8-10 years for weatherresistance, it is specially applied for internal decoration and sign board.

Color Match
For custom' color requests, we can deal as following:
1. Supply a physical sample of custom color. A color sample on metal ispreferred. If other, it is also acceptable. But the color matching rate may benot good as color on metal.
2. New color sample is usually offered by our paint supplier in 5-7 days,special color should be in 7-10 days.
3. Upon receipt of color sample, please approve in writing as soon as possible.Once you approved, we will arrange purchasing and production.
Note: Color difference maybe occurred in different production batch, so it issuggested all panels are placed in one order for same project. And keep samedirection as arrow on protective film when installing to avoid any colordifference by vision

Q:Why 5052 turn black after annealing during the production of aluminum alloy?
It has been sooted.
Q:a calculation for aluminium and copper wires?
Copper has lower resistance per unit volume, ie, a 1 cm diameter copper wire has less resistance than a 1 cm aluminum wire. BUT, aluminum is much lighter than Cu for the same diameter. If you used an aluminum wire that weighs the same as the 1 cm diameter copper wire, it would have LOWER resistance. And that is why aluminum is used in power transmission, and also in aircraft, where weight is important. to do this you calculate density resistivity which is (resistivity x density). Here is a partial table: Al 28.2e-9 Ω-m * 2700 kg/m³ = 76e-6 Ω-kg/m² Cu 17.2e-9 Ω-m * 8960 kg/m³ = 154e-6 Ω-kg/m² Ag 15.9e-9 Ω-m * 10500 kg/m³ = 167e-6 Ω-kg/m² Au 22.14e-9 Ω-m * 19300 kg/m³ = 427e-6 Ω-kg/m² Zn 68e-9 Ω-m * 7130 kg/m³ = 485-6 Ω-kg/m² Fe 100e-9 Ω-m * 7870 kg/m³ = 787e-6 Ω-kg/m² Note that Al is half that of Cu.
Q:Will an aluminum can rust under water for a period of time?
Aluminum will not rust. Only iron rusts. Because steel has iron in it, steel can rust.
Q:connecting aluminum and copper wires.?
The main problem with aluminum wiring is cold creep. When aluminum wiring warms up, it expands. When it cools down, it contracts. Unlike copper, when aluminum goes through a number of warm/cool cycles it loses a bit of tightness each time. To make it worse, aluminum oxidizes, or corrodes when in contact with certain types of metal, so the resistance of the connection goes up. Which causes it to heat up and corrode/oxidize still more. Eventually the wire starts getting very hot, the insulation melts or it damages the fixture it's attached to, and possibly even cause a fire. Anything attached to aluminum wiring should be rated for it. It will be stamped with Al/Cu or CO/ALR. Wires should be properly connected (at least 3/4 way around the screw in a clockwise direction). Connections should be very tight. Any connections using push-in terminals should be redone with the proper screw connections. Connections between aluminum and copper wire need to be handled specially. The NEC requires that the wire be connected together using special crimp devices, with a special anti-oxidant grease. The tools and materials for this are expensive - not practical to do it yourself unless you can borrow the tool. Good luck.
Q:Is the aluminum coil with damaged side still useful?
The side of tire, also called side wall, is the thinnest and most fragile. Side wall damages can be divided into swell and scratch. The swell is often caused by external force (The car is trapped in pit or on curb when you are driving fast). It can cause the cord thread break so that the rubber of the tire side wall cannot be fixed and tightened. The size of the swell is often as big as that of an one-yuan coin and will become bigger as the traveling distance increases. Under such circumstance, it is recommended to replace the tire. Scratch is usually caused by bad roads or debris on the road. It is recommended to replace the tire if the scratch in the side wall is obvious and the cord thread break. If the front wheels have such damages, the tire should be replaced as soon as possible (Because the steering, braking and driving is mainly based on the front wheels.). If there is no spare tire on site, change the front damaged tire with the rear tire and drive to an appropriate place.
Q:How to use aluminum sheet to roll a 12m-long aluminum coil with a diameter of 184cm?
According to project experience, first you should check the specification of the aluminum sheet and then design crafts such as connection method, installation and transportation according to equipment.
Q:Aluminum recovery from Aluminum dross?
OMG Zilla...you're a TC!!! i might somewhat not think of roughly God or the rest seeing via aluminum foil. It makes me experience bare. I positioned on it each and every of the time. undergo thinks that's attractive. :)
Q:Why do we recycle aluminum cans?
Heck yeah. Even an old school, smoke-belching industrialist would recycle *metal*. That's always been true. Why did people suddenly stop recycling metals? Have you PRICED metals lately? Aluminum is over a buck a pound, copper is $3 a pound, steel is over $200 a ton.
Q:What should pay attention to transporting aluminum coil?
You must ensure the good property of the aluminum coil.
Q:Is a $500 Aluminum mountain bike store bike the same as a $100 aluminum mountain bike from Walmart?
Customer service is a very important reason to buy a bike shop quality bike. A bike shop will have staff who actually know something about bicycles. They will make sure the bike is the right size for you fits you comfortably. They won't mind changing over parts (such as a saddle or a stem) to make the bike has comfortable as possible. They provide a bike with a decent warranty (on both the frame components) some free bike check-ups from a qualified mechanic. The mechanics don't mind adjusting the bike gears brakes for you, usually free of charge. And they have a wealth of knowledge, and don't mind answerering any questions you may have. These are all very good reasons to not buy a bike at a walmart store. EDIT - The dual suspension on cheap bikes are usually not very good quality. Don't expect to be able to do any real mountain biking with that kind of bike. It'll also have low quality gears brakes. Be prepared to learn how to do basic adjustments maintenance yourself, so it stays roadworthy. The metal quality might be similar, but the welding will not be as good as more expensive bikes. And what's the point in having a good frame if the components are low quality. It's the components which make the bike function as a bike.
