In the post-maintenance and consolidation of stainless steel chains, there are unique methods that are specifically divided into the following points:
1. Passivation film of stainless steel chain is attributed to thermodynamically restrained metastable state. Its maintenance performance is related to the situation medium. During the use, wash your clothes during the current period and revoke the lasting attachment of non-hazardous materials. Connotation elements. The content of martensite and the content of chromium and nickel in stainless steel have a great influence on the passivation function of stainless steel. With low nickel content, the passivation function is low. The passivation film function of martensitic stainless steel is inferior to the passivation function of austenitic stainless steel.
2. Chloride chloride ion damages the stainless steel chain extremely. During the passivation process, the chloride ion content in the passivation solution should be strictly controlled. The passivation chemical material used has a quantitative requirement for chloride ions. The production of passivation liquid water and wash water also have severe water quality requirements for chloride ions, so as to ensure that the passivated products do not adhere to chloride ions and avoid subsequent problems.
3, the use of medium stainless steel chain passivation film is attributed to the thermodynamically restrained metastability plan mouth maintenance performance and the situation of the medium. During the use, wash your clothes during the current period and revoke the lasting attachment of non-hazardous materials. Especially in the case of chloride ions, avoid the appearance of persistent chlorine ions, and dilute the mouth in water, such as stainless steel, for use in food appliances. After each contact with food, it must be washed to avoid chloride ions and damage. Film. The stainless steel chain passivation film is attributed to the thermodynamically restrained metastable state. Its maintenance performance is related to the medium of the situation. During the use, wash your clothes during the current period and revoke the lasting attachment of non-hazardous materials. For example, the container used for milk products and equipment installation, the chloride ion contained in the milk may damage the passivation film. For example, the long-term storage of the finished milk product will cause the capacity and equipment to be corroded and perforated. Therefore, it is necessary to wash the passivation film at the current time to make the passivation film. restore.
4. The appearance of the cleanliness of the child stainless steel alloy, the lower the surface roughness, the smoother the appearance, the more difficult the foreign matter Weng attached, the lower the chance of some parts of the corrosion. Therefore, stainless steel should probably use the finish appearance. In addition, stainless steel cleanliness is also very serious, after all, passivation after washing should be held in detail, because the remaining acid to promote the cathode response, so that the film breaks, so that stainless steel activation, corrosion resistance decreased drastically.
