Problems solved by technology

The coating has the following disadvantages: (1) the interlayer adhesion is poor; (2) titanium dioxide must be added to the aluminum powder paint with silver flash metal effect, so that there are more grinding processes in the preparation process of the coating; (3) ) The amount of aluminum paste added is low (limited to 2%-8%), which is not conducive to the application of special occasions
