The stainless steel sintered mesh is a new type of filter material which is made of a multi-layer wire woven mesh and is manufactured by a special lamination pressing and vacuum sintering process, and has high mechanical strength and overall rigidity. The meshes of the layers of the screen are interlaced to form a uniform and ideal filtering structure, which not only overcomes the defects of low strength, poor rigidity and unstable mesh shape of the ordinary metal mesh, but also can be used for the pore size of the material. The permeability and strength characteristics are reasonably matched and designed, so that it has excellent filtration precision, filtration resistance, mechanical strength, wear resistance, heat resistance and processability. The comprehensive performance is obviously superior to sintered metal powder and ceramics. Other types of filter materials such as fibers, filter cloth, and filter paper.

     The five-layer sintered mesh is the sintered mesh with the most widely used standard structure, generally a five-layer structure, which is divided into five parts: protective layer, filtration control layer, dispersion layer, supporting skeleton layer and skeleton layer.

     The five-layer sintered mesh filter material has uniform and stable filtration precision and high mechanical strength and compressive strength; it is an ideal fear filter material when the pressure resistance requirement is high and the filter particle size is uniform; due to its filtration mechanism For surface filtration, and the mesh hole is smooth, it has excellent backwash regeneration performance, can be used repeatedly for a long time, especially suitable for continuous and automated operation process, which can not be compared with any kind of filter material. The five-layer sintered mesh sintered mesh material is easy to be formed, processed and welded, and can be processed into circular, cylindrical, tapered, corrugated and other forms of filter elements.
