Polytetrafluoroethylene microporous membrane material, as one of the important branches in its application system, has always been the focus of technological improvement and application development field. The initial application of the uniaxial stretching film-forming method began with the sealing tape prepared by DuPont in the 1960s. In the late 1960s, mechanical stretching began to be used to develop expanded polytetrafluoroethylene films. It has a network structure composed of nodes and fibers. The nodes are composed of many PTFE particles bonded together. The fibers are made from PTFE. extends out of the particles.
Because the expanded PTFE membrane has many holes and small pore diameter (pore diameter is 0.3~10μm), the microporous film can intercept tiny dust particles, and the surface of the film is extremely smooth, making it difficult to form a thick layer of dust and easier to clean. At present, expanded PTFE membrane filter materials have been widely used in flue filtration and hot air filtration in chemical plants, power plants, carbon black plants, cement plants, spray paint plants, etc.
Polytetrafluoroethylene microporous membrane not only has excellent chemical resistance (acid, alkali, organic solvent), thermal stability It has excellent waterproof, windproof, moisture-permeable, breathable and charge storage stability properties. It has shown excellent performance in protective clothing, protective masks, waterproof and breathable clothing fabrics, and dust removal filter bags. It is a new membrane material with application prospects in many fields.
Polytetrafluoroethylene microporous membrane is pure polytetrafluoroethylene powder that has been mixed, extruded, extruded and calendered , biaxial stretching and other processes to prepare the ptfe microporous membrane. The pore size of the microporous membrane is small and uniform, and the microporous structure is a staggered arrangement of fibers. Therefore, the PTFE membrane can achieve higher efficiency with lower resistance. ptfe microporous membrane manufacturer membranes are widely used in air purification, vacuum cleaner filters, clean room filtration, industrial dust removal and other filtration.
