How to deal with the phenomenon of orange peel in electrophoresis paint film.

At present, due to the safety of electrophoresis paint environmental protection, high-quality, efficient, has been widely used in all walks of life. But does not mean that, "electrophoresis paint is so excellent, any way can go beyond spraying", in fact, or for various reasons to call swimming paint film appear such an anomaly. For example, the problem of orange peel in spraying, in the electrophoresis coating industry, there will also be

.
what's going on? How should electrophoresis coating equipment solve and avoid the phenomenon of orange peel on the surface of this paint film?
the coating film leveling effect is not good, the surface is large ripples similar to the phenomenon of orange peel called orange peel abnormality. Orange peel phenomenon in electrophoresis coating industry, common reasons and countermeasures:
1) electrophoresis paint tank liquid yanji ratio abnormal (too small);
countermeasures: appropriate increase in the amount of color slurry added.
2) impurity ions are mixed into electrophoretic lacquer liquid, and the conductivity of the tank fluid is too high.
: discharge the appropriate amount of ultrafiltration liquid, to replenish pure water and solvents.
3) the amount of electrophoresis tank liquid solvent is too large,
countermeasures: discharge the appropriate amount of ultrafiltration liquid, to replenish the pure water.
4) Increase in small molecular weight resins in electrophoretic tank lacquer liquid,
countermeasures: discharge the appropriate amount of ultrafiltration liquid, to replenish pure water and solvents.
5) Phosphate film rough, before treatment after washing incomplete,
countermeasures: strengthen pre-treatment control, to ensure that the phosphate film uniform dense, good washing.
6) voltage is too high.
: Reduce the swimming coating voltage.
