Roll coating process classification

   It is divided into two types: manual roll coating and several down roller coating. Photocurable coatings are usually mechanical roller coating (also known as roll coating), which can be divided into two categories: the same direction and the reverse direction. The direction of rotation of the paint roller of the co-roller is the same as the direction of advancement of the object to be coated, and the pressure of the roller is applied to the surface of the object to be applied, and the coating is applied in an extruded state, the coating amount is small, and the coating layer is also thin. Therefore, when the same direction roll coater is used for painting, two machines are often used in series, and the obtained coating layer is more uniform.

Roll coating process

   The roll coating method is basically suitable for the coating of large-area plates and strips, and the coating of uv-cured coatings on pre-coated, coiled, plywood, paper, cloth and plastic films of metal sheets.

Roll coating characteristics

   The roll coating method has the advantages of high coating efficiency, easy continuous production, good appearance quality of the coating film, easy film thickness control, small pollution and can be used in combination with printing, and the defect is that the shape of the object to be coated is too narrow. Can not paint three-dimensional workpieces, equipment investment is large.
