door plate roller coating machine is suitable for wood, plastic, metal, glass, glass magnesium plate and other new materials; primers and finishes for furniture, floors, cabinets, interior and exterior wall panels, decorative panels.
working principle: the evenly distributed rubber wheel and evenly distributed steel wheel are closely parallel. when the equipment is in normal operation, the two wheels rotate inward at a constant speed, and there will be a v-shaped space between the wheels. the distance between the two wheels and the rotation speed are the factors that affect the thickness and uniformity of the paint film. when the workpiece is rolled and painted, the paint will be in contact with the cots through v-shaped space, forming a uniform paint film of uniformity, and then sent out.
characteristics of door plate roller coating machine: compared with conventional artificial spraying paint, roller coating machine can achieve 100% use of paint by paint recovery device; it can realize the control of the thickness uniformity of the paint film and meet the user's requirements for rolling; the rolling coating machine can also be assembled with dryer, sander and other equipment into a more automated rolling coating line, rolling coating machine rolling nv and uv paint is appropriate.
door roller coating machine coating process features
(1) coating viscosity adjustment
the viscosity of the coating has a great influence on the uniformity and thickness of the coating. the coating viscosity is small, the wettability of the roller is large, the coating surface distribution is more uniform, but may produce insufficient amount of paint, coating thin; coating viscosity is large and the situation is opposite, may produce coating slant thick and uniform bad forehead fault. experience shows that the viscosity of roller coating is between 40 and 150s (4 cups).
coating film thickness is easy to control is one of the advantages of roller coating, in addition to the aforementioned adjustment of coating viscosity can control the thickness, but also by adjusting the speed of the roller or roller in the distance between the coating to achieve. on the same roller coating method, paint roller speed fast, thin film, slow film thickness. the distance between the paint roller and the coated material is large, the film is thick, and vice versa. for the reverse roller coating, the regulation is a little more complicated, the pressure and speed ratio between the feed roller and the coating roller will affect the coating film thickness.
