Some people ask why the stainless steel mesh belt has rusted do? Material is stainless steel mesh belt that we all know. When the stainless steel surface appears brown rust (points), people great surprise: that "Stainless steel is not rust, rust is not stainless steel, the steel may be a problem." In fact, this is a lack of understanding of the stainless steel one-sided view of the error. Stainless steel under certain conditions will be rusty. Stainless steel has the ability to resist atmospheric oxidation of stainless steel --- that is, while also having acid, alkali, salt corrosion medium capacity --- that is corrosion resistance. But its size is the corrosion resistance of steel itself with its chemical composition, plus mutual status, conditions of use and environmental media type change. Such as 304 steel, in a clean dry atmosphere is absolutely excellent anti-corrosion ability, but to move it to the waterfront, contains a lot of salt in sea mist will soon be rusty; and 316 steel is manifested Good. So instead of any kind of stainless steel, in any environment corrosion resistant, Ning 西卢 chain mesh factory is mesh belt, stainless steel mesh belt, mesh chain manufacturer. Now I plant technician to help customers analyze passivated stainless steel mesh belt What are the reasons. A chlorine ion. Chloride stainless steel mesh belt great harm. In the passivation process should be strictly controlled passivation solution of chloride ion content, the use of chemical passivation materials have limited requirements for chloride ions. Passivation solution formulated with water and wash with water to chloride ions also have severe water quality requirements, to ensure that the finished product is not contaminated with chloride ions passivated, to avoid future trouble. II. Appearance cleanliness. Pair of stainless steel alloy, the lower the roughness appearance, looks smoother, harder Weng foreign body attached, the lower the chance of ministries portion corrosion. Thus, the use of stainless steel due probably finishing appearance. In addition, stainless steel appearance cleanliness is also very tight, the final passivation after washing should be carefully hold conveyor belt, facilitate cathodic reactions due to residual acid, make the film broken, so that the activation of stainless steel, corrosion resistant features reduce violent. III. Utilization media. Stainless steel mesh belt passivation film belongs thermodynamically metastable layout suppressed port its effectiveness in the case of media-related cover. Should use current washing, remove harmless substances attached to the appearance of private long-lasting. Especially in the case of chloride ions, to avoid the appearance of chloride ions attached lasting milk diluted in water and the mouth such as stainless steel utensils for the food industry belt, after each contact with food biscuit machine belt, must wash, so as not to chlorine ions damage the passivation film. For dairy products such as container and set up equipment, furnishings, dairy products containing chloride ions have a crushing effect on the passivation film belt manufacturers, such as long-lasting costumes dairy products, will lead to capacity and set up equipment, furnishings corrosion perforation, and thus to current washing, passivation film restoration. IV. Stainless meaning elements. Martensitic stainless chromium content and nickel content of stainless steel passivation influence. The nickel content is low, passivation is low. Passivation film function better than martensitic stainless austenitic stainless steel passivation. Food Nanchong belt belt _ _ 西卢 chain network plant by plant Ningjin 西卢 chain network.
