What are the process characteristics of color coated aluminum coils?

1. After the light aluminum coil is cleaned, chromized, roller coated, baked, etc., the surface of the aluminum coil is coated with various colors of paint, that is, the color-coated aluminum coil.

2. Colored aluminum is widely used in many fields such as insulation boards, aluminum curtain walls, aluminum-magnesium-manganese roofing systems, and aluminum ceilings because of its light texture, bright colors, easy processing, and no rust.

3. Coated aluminum coils can be simply divided into: surface-coated paint, which is divided into polyester (PE) coated aluminum coils and fluorocarbon (PVDF) coated aluminum coils; Oxygen roller coated aluminum coils. Of course, there are also situations 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. Thickness of coating: It can be divided into single coating (4μm-20 μm); double coating (25μm-28 μm); Patterned aluminum coil, brick pattern, camouflage aluminum coil, fabric aluminum coil, etc.; because of different uses, they are usually used as roofing materials (aluminum-magnesium-manganese roofing system), ceiling materials (for aluminum alloy ceilings), and wire drawing boards (the surface is brushed processing), etc.

The main features of the roll coating board:

1. Good temperature resistance, the melting point of aluminum is 660 degrees, and the general temperature cannot reach its melting point.

2. Strong environmental protection, not easy to change color. Use chromium-free treatment liquid for operation; roll coating paint contains active chemical molecules, which promotes the formation of a protective layer on the surface of the material. Active chemical molecules are stable and easy to recycle, meeting environmental protection requirements.

3. Corrosion resistance Because there is a tight oxide film on its surface, it has strong adhesion, oxidation resistance, strong acid and alkali resistance, corrosion resistance, decay resistance, and ultraviolet radiation resistance.

4. The color is uniform and long-lasting, and its color is uniform and delicate. Soft and bright, avoiding the individual color difference phenomenon of traditional spraying, no matter how large the area of the ceiling is, its color and luster are always the same. Lasting and new.

5. Combination of rigidity and toughness, the strength of the board surface is extremely high. Combining rigidity and toughness, it can be cut at will, slitting, bending, pressure balancing, drilling, connection and fixing, and edge compression molding.
