When we use equipment such as stainless steel wire mesh, it is very important to take anti-corrosion measures for filtration equipment. Although many equipment are made of corrosion-resistant stainless steel, but there are always problems after a long period of use. What are the main reasons that affect the service life of stainless steel wire mesh? Today, let's take a look. First, after the stainless steel wire mesh surface treatment, to maintain adequate ventilation time and drying time must be ≥12 hours, so that such problems can be avoided, or the acid residue will corrode the product. The result not only reduces the capacity and efficiency of the equipment, but also shortens the service life of the equipment and affects the effect of sewage treatment . The second point has some brand of stainless steel wire mesh, for example, the treatment specification for 201 equipment states that if the corrosion strength of the treatment medium is high, the low thickness of the protective coating should be between 0.15 and 0.2 mm, in order to save cost, many manufacturers reduce the thickness to 0.1 mm, so it can not meet the low requirements of the design industry specifications, which directly affects the anti-corrosion effect.
Third, this may be due to human factors, in the construction process do not pay attention to the proper protection of anti-corrosion layer, a lot of steel material will scratch the anti-corrosion layer; and in the filling of filter material, if you do not pay attention to handle gently, and will be large, high hardness of the pebbles directly into the bottom of the filter will be destroyed inside the anticorrosion layer. Fourth, surface treatment is not complete. If the artificial derusting is not complete, can not reach the relevant grade requirements, primer and top coat of poor adhesion and adhesion is not enough, it will directly affect the effect of anti-corrosion. These are the main reasons that affect the service life of stainless steel wire mesh, I hope you will pay careful attention to the above issues in the procurement or use of stainless steel wire mesh.
