What is the reason for the phenomenon of blasting paint in the application process?

Color coated board I believe we have heard, and its application advantages and performance characteristics in front of everyone introduced, and today not much to say, although the performance of color coated board is very good, but in a particular case also There will be some problems, such as color coated paint blasting is a more common phenomenon, then any of the phenomena have its reasons and reasons, to understand these problems in the color coated board better think of coping methods, today For everyone to introduce color cast board explosion reasons.
   1. When the first pass with passivation tank, after adding water. Due to the density of passivation solution, such as the density of the passivation liquid is higher than the water will cause the raw material mixing is not uniform, there will be passivation layer and the substrate adhesion is not good, very easy to make the surface of the color coated paint phenomenon.
   2. There are passivation board temperature production process is 2 hours to check once, because the color coated board manufacturers in the inspection of the time when there is no regular passivation board temperature to track. Especially in winter, 2 hours of temperature changes are relatively large, will eventually cause color coated board aging, in the pressure when the time will be broken out of paint phenomenon.
   3. In the process of production of color coated plate, there are dust on the exit inspection mirror, there are dust on some of the rollers, the dust will directly affect the surface quality of the color coated plate, perhaps not at the beginning of the time, but once the time Long, or in the sun exposure will appear under the phenomenon of explosive paint.
