While passivating, it can remove oil, rust spots, weld spots, oxide layer, free iron and other dirt on the surface of the workpiece. After treatment, the surface becomes Uniform silvery white. They are all pickling + passivation two-in-one products. It also has the advanced effects of pickling, passivation and rust prevention in one.
Then let me take you through the specific process
First, before pickling and passivating stainless steel, oil, degreasing, and surface drawing compounds and other impurities must be removed. If there is a large amount of rust, dyes, and paint marks on the stainless steel surface, , tape, adhesive residue and other foreign substances, the surface needs to be cleaned first. Pre-cleaning is not necessary and can be determined according to the actual situation.

Then take out the workpiece and flush it. After the surface acid solution is completely cleaned, it can be dried and packaged.
I believe everyone has a certain understanding of why stainless steel pickling passivation liquid is chosen for the stainless steel pickling process. The following editor will introduce to you several products: stainless steel pickling liquid, stainless steel pickling passivation paste, stainless steel pickling liquid
