Aluminum sheet pre-roll coating process
Signi paints solid color, wooden grain, brushed, marble grain, chameleon etc thick sheet painting production line.
Multi-layer painting process
Multilayer spraying process with three spraying(referred to as three sprays), spray bottom paint, topcoat and hood varnish and two spraying (primer, topcoat).
Coating thickness: It can be divided into single coating (4μm-20 μm); double coating (25μm-28 μm); 3 coating (35μm-38μm).
Advantages of white painted aluminium sheet
The main features of white painted aluminium sheet are:
- Good temperature resistance, the melting point of aluminum is 660℃, and it is difficult to reach the melting point of aluminum in normal circumstances.
- Environmentally friendly, not easy to change color. Use chromium-free treatment solution for operation; roller coating contains active chemical molecules that can promote the formation of a protective layer on the surface of the material. Active chemical molecules are stable, easy to recycle, and meet environmental protection requirements.
- Corrosion resistance, because of the dense oxide film on the surface, it has strong adhesion, oxidation resistance, acid and alkali resistance, corrosion resistance, attenuation resistance, and UV radiation resistance.
- The color is uniform and durable, even and delicate, soft and gorgeous, avoiding the individual color difference phenomenon of traditional spraying. No matter how big the ceiling is, the color is consistent and permanent.
- Rigid and rigid combination, high strength of the board surface. Rigid-flexible combination, can be cut, split, curved, constant pressure, drilled, connected, fixed, blanking forming at will
