Pickling passivation and electrolytic polishing of stainless steel tanks
Jan 05, 2018

Stainless steel tank surface treatment processes are many, cleaning degreasing, rust, passivation, pickling, rust, toss, electroplating, electrophoresis, etc. are the common surface treatment, but the manufacturers will be based on their own Production process to choose a different surface treatment.


So for stainless steel tanks, pickling passivation and electrolytic polishing What is the difference? The so-called pickling passivation is to soak the entire stainless steel storage tank in the stainless steel pickling passivation until the stainless steel surface completely uniform silver white, and then remove the workpiece rinse with clean water on it.


The reason why the stainless steel storage tank for pickling passivation, mainly to remove the surface of the tank welding scars, high temperature oxide skin, making it uniform and beautiful surface color. Because the stainless steel pickling passivation solution here can be repeatedly used, not evaporated, non-volatile, no yellow smoke and hydrogen embrittlement phenomenon, so the entire operating environment is good, do not need special equipment.


However, if electrolytic polishing is required, the polished stainless steel storage tank needs to be fixed on a professional hanger, then the electrolytic polishing equipment is opened, the power supply voltage is adjusted, and the fixed stainless steel storage tank is immersed in electricity and heated To 75 degrees of electrolyte, to the surface after the light can be taken out of the workpiece, rinse.


Stainless steel tank surface brightness can be based on the requirements of various chemical manufacturers standards, can be artificially adjusted and controlled, and lasting bright as new, never peeling. In addition to stainless steel storage tanks, this process also applies to any shape of stainless steel products, and the production of high efficiency, low cost, no pungent odor, good operating environment.
