company news about What is the cause of rough surface after painting

1. It may be that the ambient temperature of the spray painting processing area is too high, which makes the solvent and diluent used in the spray painting volatilize very fast, so that when the atomized paint reaches the surface of the steel, it has been particle, of course, it cannot be leveled.
Second, it may be that the air pressure set by the spray gun is too high, resulting in the atomization of the paint is too intense, and it will also cause the evaporation rate of the solvent to accelerate. When the paint does not level the surface of the workpiece, a rough surface will appear.

3. It may be that the air pressure of the spray gun is too small, and the paint flow is too large, resulting in uneven atomization and rough paint film surface. 4. The distance between the nozzle and the steel surface is too large during the spray painting process, causing dry spray, whether it is manual spray painting or automatic spray painting. In addition, there is also a possibility that the automatic spray painting environment and working conditions are not adjusted reasonably, so that the paint fog in the spray painting room flies, and the paint fog particles fall off the surface of the paint film that has not yet dried, resulting in rough paint film.
