What is the reason for the paint layer on the surface of the color-coated board to burst? Here Zhengxin color-coated board manufacturer will tell you. There are many reasons for the surface of the color-coated board to burst paint. Now I will tell you one by one.

　　1. First of all, it is due to human reasons. There is dust on the equipment during the production process and it is not cleaned in time, resulting in poor quality of the product surface, especially the quality defects of the color plate aging paint explosion. Maybe it doesn't show at the beginning, but once it takes a long time, or under the sun's exposure, the paint will explode.

　　2. It is a problem of problem control. Due to improper problem control, the production process of the passivation plate temperature is stipulated to be checked once every 2 hours. The reason is that the staff of the color steel plate manufacturer did not regularly track the passivation plate temperature during the inspection. Especially in winter, the temperature changes greatly within 2 hours, which will eventually cause the color steel plate to fail, and the paint will be scratched and peeled during the molding.

　　3. Problems with passivators and coatings. Poor passivation of the passivator and the substrate will directly affect the adhesion quality of the coating. Later, the separation of the passivator and the substrate will cause the paint layer of the color-coated panel to burst. Then there is the problem of coatings. The quality problems of coatings can also cause the separation of coatings and passivators, resulting in paint layer bursting.
