After the metal is treated by oxidizing medium, the corrosion rate decreases significantly compared with that before the original treatment, which is called passivation metal. The main mechanism of passivation film can be used to explain the theory that passivation is due to the action of metal and oxidizing medium. When the metal surface is very thin and compact, good coverage performance can be strictly adhered to the metal passivation film on the surface. This film exists as a separate phase, and oxygen and metal compounds are usually positive. It plays the role of metal and corrosive medium, completely separates, prevents direct contact with metal and corrosive medium, makes metal basically stop dissolving, forms a passive state, and achieves the effect of preventing corrosion. Passivation is the last chemical cleaning process step, is the key step, the purpose of anti-corrosion materials. If the boiler is pickled, washed and rinsed, the metal surface is very clean, very active and susceptible to corrosion. It must be passivated immediately after cleaning the metal surface to form a protective film to prevent corrosion.


The final chemical cleaning process is the key step and the target of anticorrosive materials. If the boiler is pickled, washed and rinsed, the metal surface is very clean, very active and susceptible to corrosion. It must be passivated immediately after cleaning the metal surface to form a protective film to prevent corrosion.


All stainless steel pickling passivation treatment, remove all kinds of grease, rust, scale, solder joint and other dirt, after processing the surface becomes uniform silver, greatly improve the corrosion resistance of stainless steel, suitable for all kinds of stainless steel parts, sheet metal and its equipment.


Simple, easy to use, economical and practical, while adding high-efficiency inhibitors, antifogging agent, appear to prevent metal corrosion and hydrogen embrittlement, inhibit the generation of fog. Especially for small and complex parts, the situation is not suitable for painting, better than similar products in the market.
