  Color steel tile is rich in color, corrosion-resistant and waterproof. It is used for roof and wall of steel structure with rich color and strong decoration. But when some consumers use feedback, the phenomenon of paint explosion will appear, so what is the reason for paint explosion of color steel tile? The following is a simple analysis for you.


Adding passivation solution before adding water, due to the high density of passivation solution, if the density of passivation solution is greater than that of water, it will lead to uneven mixing of raw materials, poor adhesion between passivation layer and substrate, and easy to cause coating explosion.

  Check the temperature of color steel tile production process every 2 hours, if the employee does not regularly track the temperature of passivation plate during the inspection. Especially in winter, the temperature will change within 2 hours, which will cause paint scraping during the molding process. During the production process, dust is found on the exit mirror and some rollers. Dust can directly affect the surface quality, maybe not initially, but the paint will crack when used for a long time or exposed to sunlight.

  Through the above introduction, I believe you have more knowledge and understanding of the causes of paint explosion of color steel tile. Thank you for your patience. If you have any questions, you can contact us directly.
