Huasheng chain as the Yangtze river delta region stainless steel chain is one of professional manufacturers, maintenance and cleaning in the late of stainless steel chain has its own unique way, concrete can be divided into the following:
1. The passivation film of the stainless steel chain belongs to the thermodynamic substable layout port and its cover efficiency is related to the situation medium. In the use of current washing, remove the harmless material hang on the appearance. The essence of it. The martensitic content and chromium nickel content of stainless steel have great influence on the passivation function of stainless steel. Low nickel content, low passivation function. The passivation film of martensitic stainless steel is inferior to the passivation function of austenitic stainless steel.
2. The chloride ion
Chloride ion is very harmful to the stainless steel chain. In the passivation process, the chloride ion content in the passivation liquid should be controlled, and the chlorine ion is required for the use of passivation chemical materials. The preparation of passivated liquid water and washing water also have harsh water quality requirements for chloride ions, so as to ensure that the finished products do not have chlorine ions, so as to avoid future problems.
3. Use the media
The stainless steel chain passivation film belongs to the thermodynamic substable layout port whose cover efficiency is related to the situation medium. In the use of current washing, remove the harmless material hang on the appearance. Especially in the case of the have a chloride ion, avoid the chloride ion permanent breasts are attached to the appearance and diluted in water mouth, such as stainless steel utensils used in food industry, every time after contact with the food, all want to wash, so as to avoid the chloride ion, damage the passivation film. The stainless steel chain passivation film belongs to the thermodynamic substable layout port whose cover efficiency is related to the situation medium. In the use of current washing, remove the harmless material hang on the appearance. Such as container and set the decoration equipment for milk products, dairy products contain chlorine ions have a crushing effect on passive film, such as permanent colourful take milk product, lead to capacity as set decoration equipment corrosion perforation, consequently to current wash, restoring the passivation membrane.
Appearance cleanliness
The lower the roughness of the appearance, the lower the appearance, the less the foreign body, the lower the chance of partial corrosion. Therefore, the stainless steel should be made of the best possible appearance. In addition, the appearance of stainless steel cleanliness is also very nervous, passivation after the final washing should be careful, because the residual acid promotes the cathode reaction, make the membrane layer, thus make stainless steel activation, violent reduce corrosion resistant function
