Why does stainless steel filter also rust? Under normal circumstances, stainless steel filter is not rust. But if the use or maintenance is improper, or the environment of stainless steel is too bad, stainless steel may appear rust phenomenon.
Why does stainless steel filter also rust? First of all, we need to look at the material of the product, how is the 201 material? After a long time, rust will appear in a specific environment. Secondly, when we see the yellow or orange rust spots on the surface of the steel, we can quickly admit that this is the trace of rust. Stainless steel is a crystalline solid that is arranged atomically like a clustered toy. In addition to iron, also contains its metal components such as chromium, nickel, titanium and so on. Chromium and nickel elements have antirust function, which constitutes a protective film - blunt film, to prevent stainless steel rust. In general, as long as the film is not damaged, split or contaminated by impurities, stainless steel will not rust. Stainless steel filter is widely used in screening filtration and protective decoration, applicable to mining, petroleum, chemical, food, medicine, machinery manufacturing, building decoration, electronics, aerospace and other industries. In the stainless steel filter can be used above according to the raw materials used, a contrast work, with the extension of the use of time, the impurities in the water will block the filter element, activated carbon filter element will adsorption saturation. Therefore, generally speaking, the PP filter element needs to be replaced in 3 months, and the activated carbon filter element needs to be replaced in 6 months. The hollow fiber because it can not be cleaned, is generally placed in the back end of PP cotton and activated carbon, otherwise it is easy to plug, used as the end of water purification equipment sterilization needs to be replaced for 1-2 years. The service life of the stainless steel filter, we can according to the use of the situation, constantly repeated cleaning treatment, continuous extension of the service life, which can greatly reduce the cost of use.
Stainless steel filter can be resistant to general acid and alkali and organic corrosion, especially suitable for sulfur gas filtration, high strength, good toughness. Suitable for high pressure environment, welding, easy to load and unload, stable hole shape, uniform distribution, to ensure the stability of filtration performance. Good regeneration performance, repeated cleaning regeneration filtration performance recovery more than 90%. This article is from http://www.huanawl.com/. Reprint is prohibited without permission.
