White spots are formed on the surface, and corresponding treatment must be made at this time, but how should we deal with it?
1. Surface grinding method.
Grinding can make the ground aluminum powder fill the pores of the stainless steel pipe.
2. High voltage and high current density impact method.
In the early stage of anodizing, high-voltage and high-current shocks are used, so that the large and small stainless steel tubes that were originally cut by impurities are connected into pieces through high-current shocks.
3. Surface shot peening.
Since the selection of shot peening power will be greatly improved, the effect of such stainless steel pipes after anodizing and dyeing will be surprisingly good
