The texture preparation coating method of the texture preparation coating machine is the same as the general powder sand powder spraying, and the number and arrangement of the main fuel guns are determined according to the width and the line speed of the coil.

If the texture preparation coating machine is sprayed by the general gas heating method, the wire speed of the coil can only reach 1520m/min, and the texture preparation coating is taken away when the wife of the base is moving at a high speed, and the stacking power is only 40% to 50%; Moreover, the spray gun is arranged densely, and the film thickness of the coating film of the texture preparation is not easy to control.

The coating thickness of the texture preparation coating machine is not easy to control, and it is easy to present other coating film defects such as pitting, orange peel and the like. Nowadays, the heat that everyone is discussing will always be replaced by gas curing by radiation curing.
