Filtration mechanism and characteristics of stainless steel sintered mesh

      Stainless steel sintered mesh is a commonly used filter material. In stainless steel sintered mesh, it is pressed by a special laminate and has a high overall rigidity and mechanical strength. At the same time, the stainless steel sintered mesh is also a very good filter material, and its comprehensive performance is obviously superior to other similar products.

       It has a good filtration mechanism in stainless steel sintered mesh. When the filter cake is mechanically filtered, many inclusions larger than the mesh size of the stainless steel sintered mesh are blocked at the inlet of the stainless steel sintered mesh. As the number of blocked objects increases, a "filter cake" composed of large inclusions is formed on the surface of the inlet of the stainless steel sintered mesh. The filter cake thins the flow so that inclusions smaller than the mesh size of the stainless steel sintered mesh are also partially captured on the "filter cake". Some of the slag that cannot be floated can be blocked by the stainless steel sintered mesh, and the blocked slag itself has a filtering function, that is, two-way filtration.

         Adsorption mechanism: stainless steel sintered mesh has a large specific surface area. Metal flow is divided into fine liquid flow units through stainless steel sintered mesh to increase the contact area between metal melt and filter medium, harmful elements in metal melt and oxidation. The complex physical and chemical reaction with the surface of the stainless steel sintered mesh is adsorbed on the surface of the filter, so that the inclusions adhere to the filter frame layer by layer.
