Its application advantages and performance features are also introduced. Today we don't have much to say. Although the performance of color coated board is Very good, but in certain circumstances there will be some problems, such as color paint blasting is more common phenomenon, then any phenomenon has its reasons and reason, understand that these help in the color coated board When the problem is better to think of how to deal with it,I will introduce the reasons for the explosion of the color coated board.
1. Add the passivation solution first and then add water. Due to the density of the passivation solution, for example, when the density of the passivation solution is higher than that of water, the raw material may be mixed unevenly, and the adhesion between the passivation layer and the substrate may be poor, and the surface of the color-coated plate may be exposed to explosion. phenomenon.
2. There is also a passivation panel temperature production process which is checked once every 2 hours, because the color coated panel manufacturer's staff did not regularly track the passivation panel temperature during the inspection. Especially in winter, the temperature change within 2 hours is also relatively large, which will eventually result in the aging of the color-coated panels. When the pressure is applied, the phenomenon of scratching the paint will occur.
3. In the process of production of color coated plates, there are dust on the exit inspection mirror, and there are dust on some of the rollers. The dust will directly affect the surface quality of the color coated plates. It may not appear when it is started, but once Long, or under the sun exposure will appear burst paint phenomenon.
