The microporous precision filter element (PE, PA) is a hybrid material in which ultra-high molecular weight polyvinyl chloride powder is used as a base material and a plurality of additives are used as auxiliary materials. Microfiltration tube sintered by special processes such as activation, modification and compounding.
l High filtration precision: the particles above 0.3um can be intercepted at one time.
l High temperature resistance: PE material temperature resistance <800C, PA material temperature resistance <1000C
l Chemical resistance: resistant to various acids, alkalis, salts, aldehydes, ketones, ethers, greases, resistant to organic solvents below 90 °C, odorless, non-toxic, no foreign matter.
l Mechanical properties: high impact resistance and not easy to damage. High regeneration efficiency and long service life.
Second, the characteristics of Kun Peng mechanical microporous precision filter (PE, PA):
2.1, PE, PA sintered porous tube, the capillary pore diameter can be controlled to about 0.3 microns, the capillary pores are fine and curved, can filter solid particles above 0.3 microns, the filtrate is generally very clear, for particles below 0.3 microns, just from When filtering, there is a little bit of filtration. After filtering, the outer wall of the filter tube is trapped (the material becomes pre-coated). Once the thin filter layer is formed, the filtrate quickly clears.
2.2. PE, PA sintered porous tube is a rigid polymer sintered tube, which is a kind of rigid microporous member (not as rigid as foam). When the temperature is below 900, the tensile pressure is under the action. It is not easy to be deformed, and the filter cake formed on the outer surface of the filter tube is easily slag-removed by back-blowing with compressed air. Even if the viscous slag is high, the compressed air can be detached as long as the compressed air pressure is high. For the viscous filter cake, if the ordinary filter cloth is used, it is difficult to use the current common self-weight slag removal, vibration slag removal or back-blowing slag removal, and the effect is not good. Therefore, the microporous PE filter tube can well solve the problem of slag removal of the viscous filter cake, and the operation is simple, and the mechanical device structure is compact and uncomplicated. Further, after the filter cake is blown off by the compressed air, the air is ejected from the capillary at a high speed. The kinetic energy of the air stream forces the solid particles trapped in the capillary pores during filtration to be forced out. Therefore, the slag removal of the device and the regeneration of the filter tube are convenient, and the labor intensity of the operation is greatly reduced.
