The Key Points of Roller Coater in Roller Coating Process

Paint Viscosity Adjustment

The viscosity of the coating used by the roller coater has a great influence on
the uniformity and thickness of the coating film. When the coating viscosity is
small, the wettability to the roller is large, and the coating distribution on
the surface of the coated object is relatively uniform, but it may cause
insufficient paint supply and thin coating; when the coating viscosity is
large, contrary to the above situation, coating deviation may occur. Thickness
and uniformity are not good. Experience has proved that the roll coating method
of the roller coater deals with coatings with a viscosity between 40-150s.

Control of Coating Film Thickness

The easy control of the film thickness of the roller coater is a major
advantage of the roller-coating method. In addition to the aforementioned
adjustment of the viscosity of the paint to control the thickness, the metal
coating machine can also be achieved by adjusting the rotation speed of the
paint roller or the distance between the paint roller and the object to be
coated. For the roller-coating method of the same direction roller coater, the
paint roller rotates fast, the coating film is thin, and the speed is slow, and
the coating film is thick. If the distance between the paint roller and the
coated object is large, the coating film will be thick, and vice versa. For the
reverse roller coating method, the adjustment is slightly more complicated,and
the pressure and speed ratio between the feed roller and the paint roller will
affect the thickness of the coating film.
