The Treatment Process and Effects of Stainless Steel Pickling Passivation Solution

All the friends who have used stainless steel pickling and passivating solution know that the product has a very significant effect on the removal of grease spots and scale oxide on the surface of the stainless steel workpiece.In general, the stainless steel pickling passivation solution can restore the stainless steel surface to silver color in a very short time, and there will be no hydrogen embrittlement and corrosion.


More importantly, in practice, the whole process is simple, and there is no special requirement for the workplace, and no complex equipment or technology is required.Soaking in normal temperature can save a lot of costs.The surface of the workpiece will be uniformly white after passivation treatment by the stainless steel pickling passivation solution, and it will not adversely affect the workpiece.


In comparison, the corrosion resistance of stainless steel workpiece can be increased to more than 10 times, and the maximum of 500 hours of standard salt spray test can be achieved after the treatment of stainless steel pickling passivation solution.The whole passivation process belongs to a complete chemical reaction, which can produce a complete, compact and nondestructive passivation film on the surface of the stainless steel.


Generally, the workpiece should be soaked in stainless steel pickling passivation solution for about 10 to 30 minutes, until the product surface becomes completely subwhite.After that, rinsing with water. If necessary, it should be neutralized for about three minutes.Finally rinsing with plenty of water and trying in time.


It is important to note that passivation bath can be used by plastic tank or other, but cannot use cement tank when using stainless steel pickling passivation solution for passivation treatment, because the cement will neutralize the passivation solution.The operator needs to wear labor protection appliance during operation to avoid the direct contact of stainless steel pickling passivation liquid with the skin.
