Difference between pickling passivation and electrolytic polishing of stainless steel tanks
Nov 16, 2020

To put it simply, stainless steel storage tanks are tanks made of stainless steel, but the appearance of the equipment is easy to be corroded. Stainless steel pickling passivation and electrolytic polishing can improve the surface roughness, but what is the difference between them?


1, stainless steel electrolytic polishing: it is to be polished stainless steel on the hanging fixture, and then open the electrolytic polishing equipment, at the same time, adjusted the power supply voltage, and then has a fixed stainless steel pieces into electricity and heat to 75 degrees of electrolyte, the average time for 1-3 minutes, to surface light behind the desirable work pieces, wash clean.


2, stainless steel pickling passivation: the whole stainless steel is soaked in stainless steel pickling passivation solution, until the surface of stainless steel is uniform silver-white, then take out the workpiece and rinse the surface with clean water.


Special attention: Before the stainless steel storage tank is passivated by pickling, relevant personnel must learn the safe operation rules of cleaning and be familiar with the first-aid method of burn. In order to avoid misoperation, personnel unrelated to cleaning are prohibited to enter the construction area.
