The curtain film of the curtain coating machine is generated by the pressure of the diaphragm pump, the thickness is easy to adjust, and the distribution is uniform, and the thickness of the paint surface is not different; the conveying speed during the curtain coating can reach 80m/min, making the surface of the wood evenly painted At the same time, the coating thickness of the paint is reduced. Analysis of the cause of pitting on the surface of the coating machine?
Rain coating machine
Analysis of the reasons:
1. Inappropriate formula of UV coating or too high storage temperature, too long storage time, leakage of ultraviolet light
2. Start to pre-curing and produce small gel particles.
3. Small shavings, sawdust, and dust contaminate the paint film, caused by improper dust removal.
Recommended solution:
1. Choose a UV coating with proper formula and stable performance.
2. Store the floor under high temperature and strong ultraviolet radiation, and the storage time should not exceed 3 months.
3. Clean the environment around the paint line as much as possible, and do a good job of dust removal in the workshop, production line, and board surface.
