Passivation

After the metal by the oxidizing medium treatment, the corrosion rate than the original untreated before a significant drop phenomenon is called passivation metal. Its main mechanism of passivation film can be used to explain the theory, namely that the passivation is due to the effect of metal and oxidizing medium, when the role of the metal surface to generate a very thin, dense, good coverage performance can be rigidly attached to the metal passivation film on the surface. This film exists as a separate phase, oxygen and metal compound is usually yes. It plays metal and corrosive media, the role of completely separated, preventing direct contact with the metal and corrosive media, so that the metal basically stopped dissolved to form a passive state to achieve the effect of preventing corrosion. Passivation is the last chemical cleaning process step is the key step, the aim of the anti-corrosion material. Such as boiler pickling, water washing, rinsing, the metal surface is very clean, very activation, are vulnerable to corrosion, it must be passivated immediately after cleaning the metal surface to form a protective film, corrosion mitigation.

Full stainless steel pickling passivation treatment to remove all types of grease, rust, scale, welding spots and other dirt, the surface becomes uniform silver after processing, greatly improving the corrosion resistance of stainless steel, suitable for various types of stainless steel parts, sheet metal and their equipment.

Simple, easy to use, economical and practical, while adding a highly efficient inhibitor, fog inhibitor, appeared to prevent the metal corrosion and hydrogen embrittlement, suppressing the generation of mist. Especially for small complex parts, the situation is not suitable anointed, better than the market similar products.
