The surface of the aluminum plate is degreasing and chemically treated, and then pasted with color films of different textures. After heating and curing, the film-coated aluminum plate is formed. The flatness of the color film on the surface of the laminated board is high, and the color can be divided into high-gloss and matte. The characteristics of the laminated board are high color simulation, and the quality and grade of the lamination process vary greatly. In addition to all the materials, it is also related to its color film quality and lamination process.
For example, the quality of the color film is not good, the color of the coated steel plate is not beautiful, there is color difference, or there are stripes, and various defects will appear if the craftsmanship is not good.
The surface treatment process of the coated steel plate is as follows:
Laminated boards have primer and backcoat. The back paint mainly plays the role of preventing rust and making it last longer.
The surface of the coated steel plate is uniform and smooth, and there is no delamination, shrinkage, scratches, peeling and other phenomena. However, there are no bubbles, pits and inclusions on the surface.
