Analysis of Influencing Factors of Spreader Process on Thick Film Spreader performance

This paper mainly tests how to prepare a thick film with a certain thickness and maintain the flatness of the coating film surface. By applying the scraping method, anilox roller coating method, and screen printing method for coating, the thickness of the coating frame is adjusted. , drawdown blade angle, anilox roller winding diameter, screen mesh and plate film thickness to coat UV coating oil, and then test the thickness and surface roughness of the coated film layer, and study the effect of the coating process on the performance of the film layer Influence. It is known from the test results that a thicker and smoother coating film can be obtained by using the scraper coating method, and the scraper angle is in the range of 45b~60b. In addition, a better coating film can also be obtained by using the screen printing method, but The film thickness should be very high.
