Multi-layer metal sintered wire mesh filter element is a new type of filter material with high mechanical strength and overall rigidity, which is made of multi-layer metal woven wire mesh through special lamination pressing and vacuum sintering. The meshes of the wire mesh are staggered to form a uniform and ideal filtering structure. It not only overcomes the shortcomings of low strength, poor rigidity and unstable mesh shape of ordinary metal wire mesh, but also can reasonably match and design the void size, permeability and strength characteristics of the material, so that it has excellent filtration accuracy, filter resistance, mechanical strength, wear resistance, heat resistance, cold resistance and processability, especially ideal for filtration that requires high compressive strength and uniform filtration accuracy, and its comprehensive performance is significantly better than that of sintered metal powder, ceramics, fibers, filter cloth, filter paper and other types of filter materials. It is widely used in petrochemical, nuclear power, synthetic fiber, film, food, pharmaceutical, aerospace and environmental protection industries.
