The metal mesh is woven with metal wires, and the small pores formed can intercept some large particles and allow small particles to pass through, thereby forming a filter. However, due to the low friction of the metal wire and the poor rigidity of the filament, the technical mesh is easy to slide and displace after being impacted by intermittent force, the shape of the formed mesh will change, and the filtration accuracy is not easy to control. Moreover, the deformation caused by insufficient rigidity will have an adverse effect on the passage of fluid.
Sintered metal mesh is made of multi-layer metal braided wire mesh through laminated pressing and vacuum sintering. It has high mechanical strength and very good overall rigid structure. The meshes of each layer of wire mesh are interlaced to form a uniform and ideal filtration structure, which overcomes the shortcomings of ordinary metal meshes such as low strength, poor rigidity, and unstable mesh shape, and is more flexible in controlling the cleanliness of the equipment. Small, so that the pore size, permeability and strength characteristics of the material can be reasonably matched and designed, so that it has excellent and accurate filtration accuracy, filtration resistance, mechanical strength, wear resistance, heat resistance and processability, It makes the filtering effect easy to control, and is widely used as an ideal filtering material.
The sintered mesh is generally divided into five layers, which are divided into four parts: the protective layer, the filter layer, the separation layer and the support layer. This kind of filter material has both uniform and stable filtration accuracy and high strength and rigidity. It is an ideal filter material that requires uniform filtration particle size.
Because its filtration mechanism is surface filtration, and the mesh channel is smooth, it has excellent backwash regeneration performance (countercurrent water, filtrate, ultrasonic, melting, baking, etc. can be used), and it can be used repeatedly for a long time, especially suitable for continuous and continuous use. The automatic operation process is unmatched by any kind of filter material. It can be utilized in environments with temperatures ranging from -200°C to 600°C and for acid-base filtration.
