The main filter material of the sintered mesh filter is a multi-layer sintered mesh. Multi-layer sintering is a kind of filter material with high mechanical strength and overall rigidity after being pressed by special lamination and vacuum sintering. The filter element made of the same has the advantages of strong corrosion resistance, good permeability, high strength, easy cleaning and backwashing, accurate filtering precision, clean and clean filter material, and no falling off of the wire mesh. The metal powder sintered filter metal powder sintered filter element is made of selected spherical metal powder and sintered by special I art. It has good permeation filtration performance and high filtration precision, as well as certain strength and toughness. It has superior performance to filters made of paper, copper mesh and other fiber cloths, and is easy to assemble and disassemble.
