Coating method and repair method of blade coating machine

- May 18, 2019-

There are two ways in which the knife coater can be applied during the process of use, and the emulsion can be effectively applied to the screen by multiple wet and wet operations during use; or at each coating Then add the drying process. A machine for metering a liquid (or melt) polymer material such as a binder or a coating on a surface of a material.

In the process of production, the knife coater simply applies the glue to the film. Specific includes coating, drying, winding and tension control. The film may be PVC, PE, PET, or some paper, such as a hot melt adhesive coated on a release paper.

The blade coating machine often has the problem of wear of the transmission part during the running process, such as wear of the dryer shaft of the coating machine and wear of the bearing chamber of the winding roller. The traditional repair methods include surfacing, thermal spraying, brush plating, etc., but all have certain drawbacks: surfacing will cause the surface of the part to reach a very high temperature, causing deformation or cracking, and in severe cases, the shaft will be broken; electroplating plating It should not be too thick, and the pollution is serious, and the application is also limited. The material has good adhesion and compressive strength, and can be used to repair the wear of the coater without disassembly. At the same time, because of its metal-deficient concession, it can absorb the shock vibration of the equipment and avoid secondary
