Stainless steel filter surface passivation film in the corrosion resistance of weak parts, due to the self-excited reaction and pitting reaction, formation of small holes, coupled with chlorine ions close to form a strong corrosive solution, accelerate the speed of corrosion reaction. There are stainless steel internal intergranular corrosion cracking, all of these, the passivation film on the surface of stainless steel damage effect. Therefore, it is necessary to carry out punctual cleaning and maintenance of the stainless steel surface, in order to adhere to its rich surface and extended use of life.
