The coating liquid needs to be used within the validity period. The prepared coating liquid needs to be stored in a liquid dispensing tank with a cooling jacket, continuously stirred, and cannot be stored for too long; in the production of coating film, if the coating roller part If the position fails to transfer the coating liquid to the cast piece, it will cause missed coating. In the subsequent processing of the film, the missing position of the film cannot function as the surface it should, and will cause quality problems in the printing, aluminizing and other processes. Therefore, the missing coating must be checked and resolved during the coating production process. The waste film produced in the coating production process needs to be sorted and stored after granulation, and used as needed, and cannot be directly fed into the raw material cycle.
