Slurry dot coating part: its working principle is that the slurry pump inputs the lining cloth foundation make-up free slurry into the slurry pipe and flows into the nickel mesh through the holes on it. At the moment of the shear force of the scraper, the slurry is squeezed through the holes on the mesh and adhered to the substrate. When the support roller and the circular mesh rotate and drive the substrate to move forward, the squeezed slurry will form regular slurry dots and be evenly coated on the substrate.

The key point in the laminating process is the pressure control. The greater the pressure, the better the product quality. The specific requirements are: the pressure rise shall be stable, the pressure control accuracy shall be high, the constant pressure time shall be accurately controlled, and the pressure of the product in all directions shall be uniform. In order to meet the requirements of laminating process and product production, the main design of equipment should include four parts: loading and unloading system, heating system, pressure system and protection system.
