Introduction of roller coating process of roller coating machine
It can be divided into two categories: manual roll coating and several roll coating. Light curing coatings usually adopt mechanical roll coating (also known as roll coating), which can be divided into two categories: in the same direction and in the opposite direction. The rotation direction of the coating roller of the same direction roller coating machine is consistent with the forward direction of the coated object. The pressure of the roller is applied to the surface of the coated object, and the coating is applied in an extruded state. The amount of coating is small and the coating is thin. Therefore, when using the same direction roller coater, the two machines are often used in series to obtain a more uniform coating.
Roll coating process
Roll coating method is basically applicable to the coating of large-area plate and strip, as well as the coating of UV curing coatings for metal plate precoating, coil, plywood, paper, cloth and plastic film.
Characteristics of roll coating
Roll coating method has the advantages of high coating efficiency, easy to realize continuous production, good coating appearance quality, easy control of film thickness, low pollution, and can be used together with printing. The disadvantage is that the shape requirements of the coated object are too narrow, the three-dimensional workpiece can not be coated, and the equipment investment is large.
