Roll coating is a metal finishing process. It has the advantages of good temperature resistance, environmental friendliness, long-lasting and constant, and sturdiness. The aluminum sheet after the roll coating process is called roll-coated aluminum sheet.
Roll-coated aluminum sheet is made by degreasing and chemical treatment on the surface of aluminum sheet as a base material, and then roll-coated with high quality paint and dried and cured. Roll-coated aluminum sheet is made of the same material as the laminate. Through the high-performance roller coating process, it can more effectively control the precision and flatness of the sheet, and make the architectural decoration color uniform and delicate, soft and bright.

1. Good temperature resistance, the melting point of aluminum is 660 degrees, the general temperature can not reach its melting point.
2. Strong environmental protection, not easy to turn yellow using chromium-free treatment solution for operation, to make up for the defects of the laminate easy to change color; roll coating paint contains active chemical molecules, prompting the formation of a protective layer on the surface of the material. The active chemical molecules are stable and easy to recycle, meeting the requirements of environmental protection.
3. Corrosion resistance because of its surface has a layer of tight oxide film, with strong adhesion, anti-oxidation, acid, alkaline resistance, corrosion resistance, resistance to decay, resistance to ultraviolet radiation and other characteristics.
4. Uniform and constant color, its color is uniform and delicate, soft and brilliant, avoiding the phenomenon of color difference, no matter how large an area of the ceiling, its color luster is always the same, lasting and constant new.
5. Rigid and tough combination, the board surface strength is very high. The combination of rigidity and toughness can be cut, slit, bent, pressed, drilled, connected and fixed and edge compression molding at will.
There are two methods of roller coating: one is manual roller coating, and the other is mechanical roller coating.
Manual roller coating is made of wool felt or other porous adsorbent material roller, construction will be rolled on a flat plate first with paint, slight force, applied to the coated object. This method is suitable for large area painting of indoor building walls and ship hull decks.
Mechanical roller coating is suitable for coating on flat surfaces such as thin plates, fabrics, paper, plastic films, silicon steel sheets and other metal coils. It can be coated with different or the same paint to form a coating with various art patterns on one side or both sides. The biggest feature of roll coating is that it can utilize high viscosity paint with high solids, thick and plump coating film, better coating quality, conducive to mechanized automatic production, high production efficiency and less pollution to the environment.
