1、 There are several reasons why stainless steel mesh is easily blocked
1. The screen surface is made of stainless steel, and the screen is dried. When the humidity is greater than 8%, wet screening shall be selected.
2. For materials with more flaky particles, it is necessary to change the crushing mode of materials and the particle size distribution of different crushing processes.
3. The stainless steel mesh is easy to be blocked during use due to the following reasons:
(1) The filter material is clogged with impurities, and is rich in particles close to the size of stainless steel mesh;
(2) Spherical particles or stainless steel mesh and materials with multiple contact points are simply blocked because of the large contact area;
(3) The material is mainly fiber material; There are many flaky particles; Manufacturing stainless steel mesh plug;
(4) Rubber stainless steel mesh and other thicker stainless steel mesh, the hole planning is not reasonable, and the size is not small and the size is large, which makes the particles stuck. Because most of the material particles required for screening are irregular, the reasons for blocking are also various. When the particle size of the material is finer, the mud content is more, and the screening particle size is smaller, the water plays a decisive role in the blocking of the stainless steel mesh.
1、 What causes the stainless steel mesh to rust
1. Stainless steel has the ability to resist atmospheric oxidation, that is, rust prevention, and corrosion in the medium containing acid, alkali and salt, that is, corrosion resistance. The corrosion resistance of steel mesh varies with the chemical composition, interaction state, service conditions and environmental media type of the steel itself.
2. Stainless steel is a thin and solid fine stable chromium-rich oxide film (protective film) formed on the surface to prevent the continuous penetration and oxidation of oxygen atoms and obtain the ability of corrosion resistance.
3. Once for some reason, this layer of film will continue to be destroyed, oxygen atoms in air or liquid will continue to penetrate or iron atoms in metal will continue to decompose, forming loose iron oxide, and the metal surface will continue to be corroded.
