On the four main points of daily maintenance and maintenance of stainless steel chain
Stainless steel chain is very widely used, but many enterprises do not care about the chain, affecting the use of stainless steel chain. The passivation film of stainless steel chain is related to the condition medium of the metastable distribution port which is inhibited by thermodynamics. The use of the demand for washing, the removal of harmless substances long-lasting private attachment in appearance. If used for the production of milk containers and equipment, milk containing chlorine ions on the passivation film has a crushing effect, will lead to the capacity and installation of equipment corrosion perforation, so demand washing, so that the passivation film recovery. In fact, stainless steel chain is a maintenance and maintenance methods, mainly the following four main points:
First, the passivation film of the stainless steel chain belongs to the controlled metastable distribution port of the thermodynamics, and the shielding efficiency is related to the condition medium. The use of the demand for washing, the removal of harmless substances long-lasting private attachment in appearance.
Second, chlorine ions on the stainless steel chain of great harm. In the passivation process, the chlorine ion content in the passivation solution should be controlled severely, and the chemical material used for passivation has limited requirements for chlorine ions. The preparation of passivation liquid water and washing water also has a harsh quality of chlorine ions to ensure that the passivation of the finished product does not stick with chlorine ions, lest the trouble.
Third, the stainless steel chain passivation film belongs to the thermodynamics of the metastable layout of the sub-steady-state of the shielding effectiveness of the situation medium. The use of the demand for washing, the removal of harmless substances long-lasting private attachment in appearance. Especially in the case of chlorine ions, to avoid chlorine ions long-lasting emulsion and in the water diluted mouth such as stainless steel used in food industry utensils, every time contact with food, to wash, so as to avoid chlorine ion effect, damage passivation film.
Four, stainless steel chain appearance cleanliness. Stainless steel alloy, the lower appearance roughness, the smoother the appearance, the more difficult the foreign body attached, the lower the probability of partial corrosion. As a result, stainless steel should be used in a rough finish. In addition, stainless steel appearance cleanliness is also very tense, passivation after the final washing should be carefully held, because the residual acid liquid to promote the cathode response, so that the film is broken, so that stainless steel activation, corrosion-resistant function drastically reduced.
