Background

The existing electrochemical polishing process of a factory cannot be used for mass production due to the reason of high energy consumption, the appearance of the product is complicated, when the electrochemical polishing is carried out on a part with a blind hole, the inner surface of the inner hole cannot obtain a satisfactory polishing effect due to the fact that the surface of the inner hole is a low current density area, but the problem of energy consumption and the problem of consistency of polishing of the inner surface and the outer surface of the part can be solved through chemical polishing.

After the stainless steel showcase is processed and formed, a layer of oil stain or other chemical agents usually adheres to the surface, rust is generated on the surface due to corrosion of a use environment after the stainless steel showcase is used for a period of time, and in order to achieve attractiveness and prolong the service life, a special stainless steel cleaning agent or polishing agent is commonly used for cleaning dirt on the surface, but the existing polishing product has the problems of fast rust return, incomplete cleaning, weak polishing performance and the like.

Therefore, a new solution is needed to solve the above problems.
