Henan SIGNI is one of the lager aluminum coil coating manufacture. It uses the coating roller as the carrier of the coating. The coating forms a certain thickness of wet film on the surface of the coating roller. With the help of the coating roller contacting the object to be coated during the rotation process, the coating is applied to the coating. The surface of the object being coated. roll coating aluminum sheet is suitable for the coating of flat metal sheets, especially for high-speed coating of metal coils. Roll coating requires that the coating has good leveling, wettability and adhesion, a certain degree of hardness, flexibility and abrasion resistance, and has good weather resistance and stain resistance, and the baking and curing speed of film formation is fast.
Aluminum coil coating manufacture
The production requirements for aluminum coil coating manufacture are as follows:
①High-speed automatic coating operation, fast coating speed, high production efficiency, the line speed is generally above 60 m/min, and the maximum can reach 244 m/min (currently, the coating line speed of domestic equipment is generally 10~60m/min) ；
②No paint mist is generated, and the paint utilization rate is close to 100%;
③Suitable for coatings with various viscosities, the thickness of the paint film can be accurately controlled, and the thickness is uniform;
④The front and back sides can be coated at the same time.
