1. The oil quality is thick from the blending of the colors. Only when the makeup is duly amalgamated and mixed unevenly, can the color of the aluminum trim coil be smooth and beautiful. Thus, it’s necessary to insure that the coating has no agglomeration and moderate density.
2. The defoamer must be added in the process of blending the makeup, therefore reducing the froth generated by the machine during the mixing process. The addition quantum should be reasonable and suitable. The mixed makeup should be allowed to stand for a period of time before being used on the comber.
3. When we choose plain aluminum coil, it’s necessary to choose the aluminum coil with high flatness and complete shape. In view of the scrapes that may do during the processing, preventative measures must be taken to insure that the whole process is free from scrapes.
4. The imperfect breakers are interdicted to use. And pay attention to the changes in makeupconsumption.However, it may be that the pressure between the coating comber and the fixing comber has changed, and the pressure between the breakers must be readjusted, If there’s a large change in makeup consumption.
5. The coating process is a crucial operation link for the white aluminum trim coil. It’s it’s also a decisive process that determines the aluminum trim coil quality. For the coatings of the neat coil, the mixing rate should be rigorously acclimated according to the given rate.
6. Before oil, it’s necessary to make the makeup used unevenly spread on the coating comber as much as possible, and to insure the flatness of the aluminum coil. Only when the pressure of the coating comber is invariant, can the consistence of the terminal coating film be invariant and harmonious.
