1. After the light aluminum coil is cleaned, chromed, rolled, baked, etc., the surface of the aluminum coil is coated with various colors of paint, which is also a color-coated aluminum coil.
2. Colored aluminum is widely used in thermal insulation boards, aluminum curtain walls, aluminum magnesium manganese roofing systems, aluminum ceilings and many other fields because of its light texture, bright color, easy processing and forming, and no rust.
3. Coated aluminum coils can be simply divided into: surface coating paints, divided into polyester (PE) coated aluminum coils and fluorocarbon (PVDF) coated aluminum coils; Oxygen roll coated aluminum coil. Of course, there are also cases where one side is coated with fluorocarbon and the other side is coated with polyester; there are even cases where both sides are coated with fluorocarbon.
4. The thickness of the coating:
It can be divided into single coating (4 μm-20 μm); double coating (25 μm-28 μm); 3 coating (35 μm-38 μm); the surface patterns are various, and are also known as wood grain aluminum coil, stone grain aluminum coil, brick grain, Camouflage aluminum coils, fabric aluminum coils, etc.; because of different uses, they are usually used as roofing materials (aluminum-magnesium-manganese roofing systems), ceiling materials (for aluminum alloy ceilings), and wire drawing boards (the surface is brushed), etc.
5. The main characteristics of the roller coating board:
① Good temperature resistance, the melting point of aluminum is 660 degrees, and the general temperature cannot reach its melting point.
② It is environmentally friendly and not easy to change color. It is operated with a chromium-free treatment solution; the roller 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, meeting environmental protection requirements.
③ Corrosion resistance Because there is a tight oxide film on the surface, it has the characteristics of strong adhesion, oxidation resistance, strong acid and alkali resistance, corrosion resistance, decay resistance, ultraviolet radiation resistance and so on.
④ The color is uniform and long-lasting, and its color is uniform and delicate. It is soft and bright, avoiding the individual color difference phenomenon of traditional spraying.
⑤ Combination of rigidity and toughness, the strength of the board is extremely high. The combination of rigidity and toughness can be arbitrarily cut, slit, curved, pressure balanced, drilled, connected and fixed and edge compression formed.
