First, after cleaning, chromizing, roller coating, baking and other processing, the surface of aluminum coil with a variety of colors of paint coating, that is, color coated aluminum coil.
Two. Color aluminum is widely used in many fields, such as thermal insulation board, aluminum curtain wall, aluminum magnesium manganese roof system, aluminum ceiling, etc. because of its light quality, bright color, easy processing and forming, and no rust.
Three, coated aluminum rolls, because of the processing process and the use of different purposes, can be simply divided into: surface coating of paint, divided into polyester (PE) coated aluminum coil and fluorocarbon (PVDF) coating aluminum rolls; epoxy roll coating aluminum rolls. Of course, there is a case where fluorocarbon is coated and polyester is coated on the other side, even with fluorocarbon on both sides.
Four. The thickness of the coating:
可以分为单涂（4μm-20 μm）；双涂（25μm-28 μm）；3涂（35μm-38μm）； 表面的花纹多样，也被成为木纹铝卷、石纹铝卷、砖纹、迷彩铝卷、布艺铝卷等； 因为用途不同，也通常被大家成为屋顶料（铝镁锰屋面系统）、天花料（做铝合金天花）、拉丝板（表面经过拉丝处理）等。
It can be divided into single coating (4 mu m-20 mu m), double coating (25 mu M-28 mu m) and 3 coating (35 mu M-38 m); the surface pattern is varied, and it is also made of wood grain, stone grain, brick, camouflage aluminum roll, cloth art and so on. Because of the different uses, we are usually made into roofing materials (aluminum, magnesium manganese roofing system) and smallpox. Aluminum alloy smallpox, drawing board (surface after drawing treatment).
Five. The main features of the roll coating board:
(1) the heat resistance is good, the melting point of aluminum is 660 degrees, and the general temperature can not reach its melting point.
(2) It is environmentally friendly and difficult to discolor by using chromium-free treatment solution; the roll-coating paint contains active chemical molecules, which promotes the formation of a protective layer on the surface of the material. The active chemical molecules are stable and easy to recycle and meet the requirements of environmental protection.
(3) corrosion resistance because of its surface with a tight layer of oxide film, with strong adhesion, antioxidant, acid, alkaline, corrosion resistance, decay resistance, ultraviolet radiation and other characteristics.
(4) the color is uniform and long, its color is uniform and delicate. The soft and gorgeous color avoids the individual color difference of the traditional spray. No matter how large the ceiling is, the color and lustre is consistent.
The combination of rigid toughening and surface strength is very high. Rigid and tough combination, optional cutting, splitting, bending, balancing, drilling, connecting fixed and edge compression molding.
