Advantages of PTFE Membrane Filter Bags

Because PTFE has many unique properties and biaxial stretching, it forms a multi-layer crossed fiber-node microstructure. Make it useful in dust filtration occasions. The ordinary deep filter material becomes a surface filter through the film coating, and the dust is trapped on the surface of the filter material and cannot enter the inside of the filter material, which makes the ordinary filter material have a qualitative leap. The main advantages are:

  1. It has high filtration efficiency. The PTFE-coated dust filter bag can retain micron-level ultra-fine dust, especially PM2. 5 particles that are harmful to the human body. The efficiency is maintained at a high level and almost zero emission is achieved. At the same time, it can also be used for the recovery of ultra-fine particle products to reduce product consumption, achieve energy saving and emission reduction, and meet the requirements of emission standards.
  2. The running resistance is stable and easy to clean. Although the resistance of the film-coated filter material is higher than that of the ordinary filter material at the beginning of use, as the operating time increases, the resistance will not increase rapidly with the extension of time, and the cleaning effect is good, the cleaning cycle is long, and the cleaning pressure is low, reducing the friction and friction coefficient between the dust and the filter material.
  3. High air flux and long service life. Because the surface of the film-coated filter material is smooth and water-repellent, the dust is thoroughly cleaned, and a high ventilation rate is always maintained, which better solves the contradiction between filtration and dust removal, thereby improving the service life of the filter bag. Polytetrafluoroethylene (PTFE) is known as “the king of plastics” for its excellent and unique properties. Under the situation that the world is paying more and more attention to environmental protection and sustainable development, the application of PTFE in bag filter media (bags) can be said to be in the ascendant and has broad application prospects. It is believed that various PTFE-based yarns and textiles, film and emulsion treatment agent and other new products will emerge one after another, laying a more solid foundation for the upgrading of bag filter bag products.
