The curtain coater is an automated industrial machine. The curtain film of the curtain coater 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, so that the paint on the surface of the wood is evenly reduced. The coating thickness of the paint. Analysis of the causes of small pits on the surface of the spray film of the spray coater?
Drench coater
Analysis of the reasons:
1. The UV coating formulation is improper or the storage temperature is too high, the storage time is too long, and the ultraviolet light is leaked.
2. Start pre-curing, resulting in small gel particles
3. Small shavings, sawdust, and dust contaminate the paint film, caused by improper dust removal.
Suggested solutions:
1. Choose a UV coating with proper formula and stable performance.
2. The storage time should not exceed 3 months for floor storage under high temperature and strong ultraviolet radiation.
3. Try to clean the surrounding environment of the paint line, and do a good job of dust removal in the workshop, production line, and board surface.
