Product Description:

1.Structure of Product Description

 

Color Coated Aluminium Coil is widly used in roofing, wall and decoration.  There are two kinds of painting. One is PE coated and the other is PVDF coated. Usually in the open air, we recommend PVDF Coated. It can last 15-20 years. Now painting brand can be China domestic brand, PPGI and Becker. The price is different. It depends the final customers requirement and usage environment.

 

2. Main features of the product

a.Good quality --Our color coated aluminium coils are exported to Europe. We have passed European SGS inspection.

b.Professional after-sale service--CNBM have rich experience in export process.


c.Fast delivery time--Usually our delivery time can be controlled within 30 days.

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:mass of 3.45 moles of Aluminum sulfate?
Aluminum sulfate is Al2S3, so you got two atoms of aluminum and three of oxygen. Hence the molar mass of aluminum sulfate is: 2X16 (two times molar mass of oxygen) + 3X32 (three times molar mass of sulfur). Keep in mind that the molar mass of an elements equals its mass number. We have 128 grams per mole or 128 pounds per lb-mol. Since you have 3.45 moles of Al2S3 you just have to do 3.45 times 128 = 441.6 grams
Q:Anti-Perspirant without Aluminum?
those crystal ones like health food stores.
Q:aluminum nitrate in water: neutral, basic, or acidic?
Aluminum nitrate is the salt produced by the reaction of aluminum hydroxide and nitric acid. Nitric acid is a strong acid. Aluminum hydroxide is a realtively weak base. So the salt will be acidic.

Q:Can aluminium oxide react?
Like hell, it can.
Q:Replacing aluminum windows?
New windows aren't that expensive. They are plastic now because they insulate better. You just cut around the frame with a skill saw and leave the flange in place. pull out the old window and nail or screw the new frome on the outside of the wall use caulking and new trim boards. Just do one at a time as you can afford it.
Q:what are the safety precautions in handling Aluminum?
Aluminum as a solid is very safe; although non-nutritious (your body does not require it), its accumulation in tissues is apparently not directly harmful. Individuals who work years of their lives in handling aluminum have no higher incidence of Alzheimer's disease than those that do not. As a powder- particularly very fine powders- aluminum is extremely hazardous with respect to its combustibility, and is used in fireworks (sparklers, for example). When it burns, it is extremely hot, and extinguishing it should not be attempted without training and the correct tools- usually salt or Purple K extinguishing agent. However, it burns so quickly that it will usually be out before attempts can be made.
Q:Will anodized aluminum rust? Should I oil the exterior of my AR-15 to prevent rust?
As chris w said, aluminum doesn't rust and anodizing prevents corrosion. Have you considered simply reading the manual that comes with your rifle? The manual includes instructions for cleaning and care, and if you don't have one, you can download it from SW's website.
Q:When connecting aluminum service conductors to a breaker panel, do I need to use antioxidant?
Aluminum to Aluminum they say you do not need an inhibitor. I have still aways used it as has every electrical contractor I have worked for for 30 years. Utility companies use it on all meter bases as well. The oxidation can still be persistent so I suggest you use it and torque them to the manufactures labeling. So many people over tighten the conductors and this is a major problem because aluminum is very soft it does have a torque guideline for each conductor size as well as the lug it is attached to.
