The difference between color coated board and sprayed board production line

This article will share with you the difference between the color-coated board and spray-coated board production line. Before the color-coated board is used, the spray-painted board production process has been used. Nowadays, the spraying production line is basically replaced by the color-coated board production line.

The spraying plate production process originally evolved from the process of spraying powder after forming the metal. This process is technically a big step ahead of forming spraying, and it is also called powder spraying production line. Although the powder spraying production line is also a continuous production method, because its coating process is still in the form of spray guns, there is no qualitative change compared with the forming spray process. There are still low efficiency, high labor intensity, large paint waste, and coating film. Problems such as uneven thickness.

Therefore, the spraying production line has basically been replaced by the color-coated board production line. Color-coated plate is a composite material made by strictly degreasing and chemically treating the surface of the steel plate, and then drying and curing the special paint or film on the surface of the steel plate. It turns the traditional spray coating into continuous coating of steel plate, which is convenient for surface treatment and coating quality control, and there are no defects such as edges and dead corners that are easy to produce in coating.

Compared with traditional powder coating production, color-coated panels have the advantages of high efficiency, energy saving and environmental protection. At the same time, its overall cost is also cheaper than spray-coated panels. The use of color-coated panels can reduce the cost of thin-sheet coating products by 5% to 10%. , Saving energy I/6～1/5. However, the spraying process has low efficiency, high labor intensity, large paint waste, and uneven coating film thickness. Therefore, the spraying production line is basically replaced by the color-coated board production line.
