Stainless SteelMesh beltHow to clean and maintain?

1. The passive film of stainless steel mesh belt belongs to the metastable layout controlled by thermodynamics, and its protection efficiency is related to the medium condition. Use the process to regularly clean, remove the long-term adhesion of harmless substances on the surface. internal components. The content of martensite and chromium nickel in stainless steel has a great influence on the passivation function of stainless steel. If the nickel content is low, the passivation function is low. The passivation function of martensitic stainless steel is not as good as austenitic stainless steel.
  
2. Chloride ion is very harmful to stainless steel mesh belt. During the passivation process, the chloride ion content in the passivation solution should be strictly controlled, and the chemical raw materials used for passivation have limited requirements for chloride ions. The water for preparing the passivation solution and the washing water also have strict requirements on the water quality of chloride ions to ensure that the passivation product does not adhere to chloride ions and avoid future problems.
  
3. The passive film of stainless steel mesh belt in the service state is due to the metastable arrangement of ports constrained by thermodynamics, and its protection efficiency is related to the condition medium. Regular cleaning during use to remove long-term attachment of harmless substances on the surface. Especially in the presence of chloride ions, long-term adhesion of chloride ions to surfaces and dilution openings in water, such as stainless steel used for tableware, should be avoided. Clean after each contact with food to avoid damage to the passivation film due to the action of chloride ions.
  
The passive film of stainless steel mesh belt belongs to the metastable layout controlled by thermodynamics, and its protection efficiency is related to the medium condition. Regular cleaning during use to remove long-term attachment of harmless substances on the surface. For example, for containers and equipment used for dairy products, the chloride ions contained in the dairy products can damage the passivation film. For example, long-term wear of dairy products can lead to production capacity and equipment corrosion perforation. Therefore, periodic cleaning is required to recover the passive film.
  
4. The surface cleanliness of the sub-stainless steel alloy, the lower the surface roughness, the smoother the surface, the more difficult it is for foreign matter to adhere, and the lower the probability of corrosion of each part. Therefore, stainless steel should try to choose the finishing surface. In addition, the surface cleanliness of stainless steel is also very strict. The final cleaning after passivation shall be carried out in detail. Since the residual acid promotes the cathodic reaction and membrane breakage, the stainless steel is activated and the corrosion resistance is seriously reduced.
