The powder sintered filter element is composed of metal spherical powder, with smooth aperture, uniform size, small initial resistance, and can be repeatedly cleaned and recycled; During the manufacturing process of the filter element, no adhesive is added, and there is no shedding matter or dissolved matter. At the same time, the powder sintered filter element is first made by cold isostatic pressing technology, using rubber or plastic materials as the sheathing mold at room temperature, and using liquid as the pressure medium to shape the powder, and then by high-temperature vacuum sintering. It has stable shape, high strength and good permeability, high temperature and high pressure resistance, strong acid and alkali resistance, oxidation resistance, and its anti impact and alternating load capacity is also far higher than other metal filter materials. Because the metal material has high strength performance, when the filter cake on the surface of the powder sintered filter element reaches a certain thickness, the filter element can be cleaned by backwashing or back blowing with a certain reverse pressure, so that the filter element can be used again. Therefore, the service life of the powder sintered filter element is also longer, which can effectively reduce the operation cost when used.

Customer case
Zambian customers purchase sintered powder filter cartridges for solid gas separation in the field of environmental protection. The mesh of each layer of wire mesh can be staggered according to customers' requirements to form a uniform and ideal filter structure, which not only overcomes the shortcomings of low strength, poor rigidity and unstable mesh shape of ordinary wire mesh, but also can reasonably match and design the pore size, permeability and strength characteristics of materials, Better realize the ideal working environment.
