Product Description:

1.Structure of Polyester Coated Aluminum Coil for Construction Description

Color coated aluminum coil is aluminum coil after cleaning, coating, and baking. Surface of aluminum coil can be painted to any color. Dong Chuan color-coated aluminum coil and aluminum sheet coils mainly come from Southwest Aluminum, Nanping, Chinalco, Ruimin, etc. which are the best raw materials suppliers domestically. Our coating paints are mainly from American PPG and Swedish Becker.

Q:what's the difference between aluminum sheet detergent and central air-condition detergent?
Central air condition cleaning includes air-cooled condenser cleaning and water-cooling condenser cleaning, if it’s air-cooled condenser cleaning, you can use aluminum sheet detergent.
Q:why does the hardness of 2024 aluminum sheet not increase but decrease after thermal treatment?
The hardness of 2024 aluminum sheet will decrease after thermal treatment(solution treatment), and it will increase after aging treatment.
Q:why is copper sheet but not aluminum sheet that becomes the negative pole after putting copper sheet and aluminum sheet connected with wire into concentrated nitric acid?
According to metal reactivity series order table, aluminum has a better metallicity, but it will be passivated soon after contacting concentrated sulfuric acid, and won’t react again. But copper and concentrated sulfuric acid can react continually. So aluminum sheet becomes the positive pole after passivation.
Q:Could copper wire be welded with aluminum sheet?
Copper wire could be welded with aluminum sheet, and it needs to use low temperature welding method, if copper wire is in the unit of millimeter and aluminum sheet is also in the unit below 1 mm, you can use electric soldering iron to heat it as hybrid welding and choose low temperature welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. As for the large aluminum sheet, you can take liquefied gas multihole lance as heat source, then choose the same low temperature materials as welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. Welding fundamentals of these two welding methods: both of them are use heatable heat source to heat the matrix to 179 degree, the melting point of WEWELDING M51, then use matrix’s heat conduction to melt welding wire, completing welding. The process of melting welding wire is the process of smearing the welding wire with flux into welding area, melting welding wire completely depends on matrix’s heat conduction.
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
Q:whst should I notice while welding aluminum sheet and aluminum block?
two types of aluminum reach melting points, aluminum block must be preheated when you weld them with small current, you will know how to do it. You can use argon-arc welding back and forth, preheat it with small current.
Q:When water continually sprays on the aluminum sheet, how to avoid corrosion of aluminum sheet and keep its water resistance?
Don’t worry about it, after aluminum contacts water or air, a layer of oxide film will generate on its surface to separate aluminum from the water or air and protect it, so it won’t be erosive.
Q:Could ring-pull can be transformed as aluminum sheet?
Yes, but the ring-pull cans contains fewer aluminum.
Q:what’s the difference of activated aluminum and aluminum sheet?
you can use weak acid ,weak base solvent or steam to clean the oil and dirt on the surface, it's activated aluminum, their difference is that activated aluminum has porous structure oxide film.
Q:does aluminum sheet has a function of magnetism isolating?
