Multi-layer sintered wire mesh is used to suppress multi-layer laminated by a special process and vacuum sintering of metal made of woven wire mesh, with high mechanical strength and the overall rigidity of the structure of a new type of filter material.. its layers of wire mesh interlock to form a uniform and ideal filter structure, not only to overcome the low strength, poor rigidity, mesh shape non-instability of ordinary wire mesh, but also adjust the material pore size, permeability and strength characteristics, making it excellent filtering accuracy, filtering resistance, mechanical strength, wear resistance, heat resistance, and are processed, comprehensive performance much better than sintered metal powder, ceramics, fiber, filter cloth, filter paper, and other types of filter material. At present,our multi-layer sintered wire mesh series products are widely used in aviation, aerospace, petroleum, chemical industry, metallurgy, machinery, pharmaceutical, food, synthetic fiber, film, environmental protection and other industrial fields in the filtration and purification, gas - solid, liquid - solid and gas - liquid separation, divergence cooling, gas distribution, flotation transfer, fluidized bed, gas samples collected as well as shock absorption, silencers, flame-retardant, etc.
