Rectifier: Three-phase 380V, rectified current, according to customer's workpiece size. Operating voltage 8-20v.
The principle of stainless steel electrolytic polishing:
The currently accepted theory is mainly the theory of stainless steel electrolytic polishing mucosa. This is: metal ions are separated from the workpiece and phosphoric acid forms a phosphate film adsorbed on the surface of the workpiece.This mucous membrane is predicted to be thinner and thicker at rest, because it is predicted that the high current density will quickly dissolve, the fluidity of the mucus membrane, the irregularities change, rough The surface gradually becomes smooth.
Advantages of stainless steel electrolytic polishing:
(1) The interior and exterior of the same color are flattened without gloss and mechanical polishing without rest.
⑵High production efficiency and low cost.
⑶ Increase the corrosion resistance of the surface, suitable for all stainless steel.
