Why is sintered filter element better than ordinary filter element?

Sintered metal mesh is made of multi-layer metal woven wire mesh through lamination pressing and vacuum sintering. The meshes of each layer of wire mesh are staggered to form a uniform and ideal filtering structure, which overcomes the shortcomings of low strength, poor rigidity and unstable mesh shape of ordinary wire meshes, and has better control flexibility on the cleanliness of the equipment. Therefore, it is possible to reasonably match and design the pore size, permeability and strength characteristics of the material, so that it has excellent and accurate filtration accuracy, filtration resistance, mechanical strength, wear resistance, heat resistance and processability. The filtering effect is easy to control, and it is widely used as an ideal filter element.

Because its filtration mechanism is surface filtration and the mesh pores are smooth, it has excellent backwash regeneration performance (countercurrent water, filtrate, ultrasonic, melting, baking, etc. can be used), and can be used repeatedly for a long time, especially suitable for continuous and automated process.

Sintered filter element processing technology

The main difference between the sintered filter element and other filter elements is the use of a large number of high-precision welding processes. The sintered mesh is welded on the end caps at both ends through stainless steel welding wire. During the welding process, the sintered mesh cannot be burned to prevent partial burnout, which will cause the filter element to fail to filter. Therefore, the welding environment must be argon gas during the welding process. Protect.

During the welding process, all welding tools and special welding equipment must be used, and the welding technical requirements for workers are also relatively strict.
