Stainless steel wire mesh has good corrosion resistance, high temperature oxidation resistance, low temperature resistance performance. Therefore, it is widely used in industries such as screening and filtration under acid-base environment. It’s main function is to prevent corrosion and rust.
The corrosion resistance of stainless steel wire mesh mainly depends on the passivation film on its surface. If the film is incomplete or defective, the stainless steel will still be corroded. Passivation treatment is generally adopted in engineering to make stainless steel have greater corrosion resistance potential.
Stainless steel wire mesh surface cleaning, pickling and passivation can maximize corrosion resistance and prevent product contamination. It is generally the petrochemical filtration industry that requires stainless steel wire mesh to be pickled and passivated, because these devices are in direct contact with corrosive media.
For other industries, if the purpose of anti-corrosion is not used, the stainless steel wire mesh used does not require pickling and passivation, as long as it is clean and beautiful.
The filter screen made of stainless steel wire mesh has the following advantages:
1) Simple cleaning: The single-layer filter material has the characteristics of simple cleaning, and is especially suitable for backwashing.
2) Corrosion resistance: The stainless steel raw material itself has high corrosion resistance and wear resistance.
3) High strength: high-quality materials, high pressure resistance, can withstand greater working strength.
4) Convenient processing: high-quality materials can be cut, bent, stretched, welded and other processes.
5) The filtering effect is very stable: high-quality raw materials are used in the production process, which is not easy to deform during use.
