Does The Stainless Steel Pickling Paste Have Strong Oxidization?

In fact, the use of stainless steel pickling passivation paste of various stainless steel parts, the reason why it can achieve very good results when using stainless steel pickling paste to clean various stainless steel workpiece, there is a large part of the reason is that the stainless steel pickling paste have very strong oxidization.This is because a part of strong oxidizing acid is added so that the redox reaction can be completed in a short time during the pickling passivation process to restore the original color of the stainless steel.


When using pickling paste,we must control the using amount of stainless steel pickling passivation paste. On the one hand, we should give full play to the role of passivation paste, save the cost and reduce cost as much as possible.On the other hand is to ensure that the pickling passivation paste to achieve ideal effect.Therefore, when dealing with the first analysis the stainless steel workpiece material first , but also pay attention to oil or scale on the surface of stainless steel when pickling and passivation treatment. If necessary, the cleaning should be done first, then using the stainless steel pickling passivation paste.


Under normal circumstances,clean surface of stainless steel can be coated with a thickness of 1mm-2mm passivation paste to meet the requirements.Then keep it on surface of stainless steel products for 5-30minutes.In the process of operation, it is better to brush several times with the brush.After the oxide scale and rust is completely cleared , rinsing with water or lime water and avoid rusting.

If it is the first time operation or no have using experience, it is necessary to have a small trial first, and then use it in large quantities after the effect is confirmed.Generally speaking, we mainly use the stainless steel pickling passivation paste for the welding joint of the stainless steel large equipment and the pickling and passivation of the stainless steel products surface.


Compared with the traditional process of oil removing,pickling and passivation,using stainless steel pickling passivation paste means that it can be carried out simultaneously with oil removing,pickling and passivation.The whole operation is not only simple, but also very economical.In the process of stainless steel pickling passivation, there is no need to set up special site and equipment, which can save energy and save time.
