2019-03-19

In recent years, the use of stainless steel storage tanks more mature and a wide range of processes have stainless steel pickling passivation and stainless steel electrolytic polishing and other surface treatment processes. However, many chemical manufacturers are not very clear about the difference between stainless steel pickling passivation and electrolytic polishing.

Stainless steel storage tank: stainless steel pickling passivation. It is to soak the whole stainless steel part in the stainless steel pickling passivation solution until the surface of the stainless steel part is completely uniform and silvery white, and then take out the workpiece and rinse the surface with clean water. Most of the stainless steel products manufacturers with pickling passivation requirements are due to the need to remove the surface solder scar and high temperature oxide scale, and to make the surface color of stainless steel parts uniform and beautiful. The scope of application of this process is relatively wide: for example: stainless steel chemical pipeline treatment, stainless steel welding parts pickling treatment, stainless steel valve cleaning treatment. Because the stainless steel pickling passivation solution can be recycled repeatedly, it does not evaporate, does not volatilize, does not produce yellow smoke and hydrogen embrittlement, so the operating environment is good, and no special equipment is needed, because it is favored by the majority of stainless steel products manufacturers.
Stainless steel storage tank: stainless steel electrolytic solution polishing. The stainless steel to be polished is fixed on a professional hanging tool, then the electrolytic polishing equipment is turned on, the power supply voltage is adjusted at the same time, and then the fixed stainless steel parts are immersed in an electrolyte that is energized and heated to 75 degrees. The general time is 1-3 minutes, and the workpiece can be taken out and rinsed after the surface is bright. The brightness of the table can be adjusted and controlled according to the different requirements of various chemical manufacturers. The surface of the stainless steel workpiece after the electrolytic polishing treatment is absolutely consistent with the bright and delicate effect, and the surface gloss can reach 8K mirror effect. And lasting bright as new, never peeling. At the same time, this process can be applied to any shape of stainless steel products, general all 200 series, 300 series, 400 series of stainless steel surface polishing, high production efficiency, low cost, no pungent smell, good operating environment, is the best choice to replace the traditional mechanical and manual polishing.
