Stainless steel sintered mesh is a new type of filter material with high mechanical strength and overall rigidity. It adopts a special lamination and vacuum sintering process and is made of multilayer metal wire mesh. The screens of each layer cross each other to form a uniform and ideal filter structure, which not only overcomes the ordinary low-strength, poor-rigidity metal screen, and the instability of the mesh, but also has a reasonable design for the pore size, permeability and strength characteristics of the material. It has excellent filtration accuracy, filtration resistance, mechanical strength, wear resistance, heat resistance and processability, and its overall performance is better than sintered metal powder, ceramics, fibers, filter cloth, filter paper and other filter materials.
