Roller Coater in Roller Coating Process Key Points

Paint Viscosity Adjustment

The viscosity of the coil coaters 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 coating line machine deals with coatings with a viscosity between 40-150s.

Control of Coating Film Thickness

The easy control of the film thickness of the coil roller coaters 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 coating machine 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.

The Coil Coating Process

The continuous process of coil coating starts from an untreated metal plate coil, which is developed, processed, coated, cured, rewound, packaged and shipped at a speed of 100-200 meters per minute. This process can be applied to one or both sides of the metal plate, and up to three coats of paint can be applied and cured. The most common types of sheet metal are color coating machine, galvanizing line coating machine, silicon steel roller coating machine.

Coil Coaters Application

Coil coating has a wide range of applications, and is the preferred product for precoating metal in the furniture, construction, household appliances and transportation industries.

Coiled materials are closely related to people. Many buildings such as factories, high-speed railway stations, airports, etc. that people see are made of color coated coiled materials, and their color is the display of paint.

Coil coating is generally used for color coated coil and other building materials, and roll coating on aluminum zinc or galvanized substrate to prevent corrosion, rust and beauty of plates.
