What are the surface treatment methods of the filter? After the filter net is processed and manufactured, the surface treatment is generally needed to make the product beautiful, rust-proof and corrosion-proof. Generally speaking, there are two kinds of filter surface treatment, galvanized and polished. Here are two techniques: 1. Galvanizing, I. E. Cold Galvanizing, is the application of galvanizing on the surface of the filter screen, the main process is to dip the filter screen and the zinc block in the electrolyte at the same time, respectively, through the positive and negative electrodes of the direct current, the finished coating is uniform, the surface of the filter screen of zinc plating in acid electrolyte is brighter than that of the filter screen of zinc plating in alkaline electrolyte, but there is no difference in 2 kinds of quality. This process is mainly applied to the surface treatment of low carbon steel wire (iron wire) filter screen 2.5% . For stainless steel filter products, the commonly used surface treatment is polishing, polishing methods have mechanical polishing, chemical polishing, electrochemical polishing three methods, each has its own advantages and disadvantages.www.huanawl.com
(1) high brightness of mechanical polishing. Its disadvantage is the Labor intensity is big, the pollution is serious, moreover its luster can not be consistent, the gloss maintains the time is not long, the hair is stuffy, rusts. Wire Mesh deep processing products are more suitable for processing simple, medium and small products. (2) the advantages of chemical polishing are less investment in processing equipment, high polishing speed, high efficiency and good corrosion resistance. Its disadvantage is poor brightness, gas overflow, the need for ventilation equipment, heating difficult. The screen deep processing product is suitable for processing small batch of complex parts and small parts of the product with low brightness requirements. (3) the advantages of electrochemical polishing are long mirror gloss, stable process, less pollution, low cost and good anticorrosion. Its disadvantages are high anti-pollution, large one-time investment in processing equipment, complex parts to tooling, auxiliary electrodes, a large number of production also need cooling facilities. Suitable for mass production, this deep-processing products are mainly used in products, export products, tolerance products, the processing process is stable, simple operation. The above is our commonly used several kinds of filter commonly used surface treatment, I hope you can according to the actual needs of a better choice.
