Passivation Mechanism And Passivation Performance Analysis Of Stainless Steel Pickling Passivation Paste

At present, I believe everyone is already very familiar with the main role of stainless steel pickling passivation paste,so we often use the passivation paste makes the target object produces anti-corrosive substances.In the process,do you know the passivation mechanism of stainless steel pickling passivation paste?


Normally, before passivation treatment, firstly we need to clean the surface of the preparing workpiece.It is mainly to remove the stains and oxidation such as oil stains, rust, a variety of substances attached to the surface of workpiece.Because stainless steel pickling passivation paste is sensitive to these substances, if cleaning is not complete, then it may not be able to achieve the desired anti-rust effect, or even go down the drain.


Therefore, we hope everyone will realize the importance of this link. Next, when the surface of the workpiece after the stains clean up,passivation can be started.At this time,stainless steel pickling passivation paste can be evenly applied to the surface of the workpiece.Then we can wait for some time. It should be noted that reasonable control of the thickness of the smear and waiting time are very important for different materials.


Specific time can refer to its instructions.After the treatment is completed, promptly rinse with water.Then we can see that the surface of the workpiece has become the same as the new, and it has a strong anti-corrosion ability.How did this magical phenomenon come about?


At first, after we apply the stainless steel pickling passivation paste evenly on the surface of the workpiece,it will have a chemical reaction with the object.Thus slowly generating a chemical film, the active properties of the substance become lazy, making it difficult to produce chemical effects with the atmosphere.The film also insulates the surface of the metal from direct contact with the atmosphere, creating a second layer of protection.
