Sintered felt has extremely high mechanical strength and compressive strength; it is ideal for filtering materials with high requirements for compressive strength and uniform filtration particle size; since its filtration mechanism is surface filtration and the mesh pores are smooth, its It has excellent backwash regeneration performance and can be used repeatedly for a long time. It is especially suitable for continuous and automated operation. It is incomparable to any kind of filter material.
The sintered felt filter filter material is originally clean, and its material structure shape is fixed. In the initial stage of filtration, when the dust-containing fluid passes through the pore channel of the filter material, under the action of various filtration mechanisms, the contaminated particles are mixed. The fluid will quickly fill up and fill the various channels of the filter material. The sintered felt is made up of a plurality of stainless steel woven meshes of the same kind or different, which are repeatedly pressed, rolled and repeatedly subjected to vacuum sintering at 1260 ° C, and then formed by diffusion and solid solution. Strength and overall rigidity; the sintering process in the sintered felt is that when the inorganic solid compound is prepared by the solid phase reaction, the rate of the reaction is controlled by the diffusion process, and a relatively high temperature is often required for the reaction to proceed efficiently.
Other solid compounds are solid-liquid phase compounds which undergo decomposition reactions upon melting, so sintering should generally be carried out below the melting point of the product to ensure a uniform phase. The sintered mesh has good mechanical strength and rigidity. Together with the sintering process, the sintered mesh can withstand a pressure difference of up to 2.4 MPa. If the working pressure is too large, the compressive felt has insufficient compressive strength and mechanical strength, then the equipment will be deformed. The mesh is enlarged, the filtering precision is weakened, and the service life of the device is greatly reduced. At this time, it is estimated that you have to replace the new sintered mesh.
