Passivation

Metal oxide medium after treatment, the corrosion rate was significantly lower than the original untreated phenomenon known as passivation metal. The main mechanism of passivation film can be used to explain the theory that passivation is due to the role of metal and oxidizing medium, when the metal surface produces a thin, dense, good coverage performance, can be firmly attached to the metal passivation On the surface of the membrane. This film exists in a separate stage, oxygen and metal compounds are usually. It plays the role of metal and corrosive media, complete separation, to prevent direct contact with metals and corrosive media, the basic dissolution of the metal to form a passive state, to achieve the anti-corrosion effect. Passivation is the last step of the chemical cleaning process, the key step is the purpose of anti-corrosion materials. Such as boiler pickling, washing, rinsing, the metal surface is very clean, easily activated, easy to corrosion, the metal surface must be immediately after passivation passivation to form a protective film, corrosion inhibition.


The last step of chemical cleaning is a crucial step in preservative materials. Such as boiler pickling, washing, rinsing, the metal surface is very clean, easily activated, easy to corrosion, the metal surface must be immediately after passivation passivation to form a protective film, corrosion inhibition.


All stainless steel pickling passivation, remove all kinds of grease, rust, dirt, solder joints and other dirt, the surface becomes uniform after processing silver, greatly improving the corrosion resistance of stainless steel for a variety of stainless steel parts, sheet metal Pieces and equipment.


Simple, easy to use, economical and practical, while adding high-performance corrosion inhibitors, corrosion inhibitors to prevent metal corrosion and hydrogen embrittlement, inhibiting the generation of fog. Especially for small complex parts, the situation should not be oiled, better than similar products in the market.
