Although the performance of color steel plate is excellent, there are also some problems under certain circumstances. For example, color steel plate explosion paint is a common phenomenon, so any phenomenon has its reasons and reasons. Here is a share:
color steel plate explosion paint phenomenon reasons.
1. Passivating liquid is added first, then water is added. Because of the density problem of passivation solution, such as when the density of passivation solution is higher than that of water, the mixture of raw materials is not uniform, and the adhesion between passivation layer and substrate is not good. It is very easy to cause the phenomenon of paint explosion on the surface of color steel plate.
2. There is also a passivation plate temperature production process is required to check once every two hours, the reason is that the staff did not regularly track the passivation plate temperature during the inspection. Especially in winter, the temperature changes within 2 hours are relatively large, which will eventually lead to the aging of the color steel plate, and scratch the paint when pressing.
3. In the process of color steel plate production, there is dust on the exit inspection mirror and on some rollers. The dust will directly affect the surface quality of the color steel plate. It may not appear at the beginning, but once the time is long, or in the sunshine, the phenomenon of paint explosion will occur.
