PTFE bag for dust removal bag selection (top)
Dec 14, 2021PTFE dust bag is widely used and has good effect, especially in large-scale high temperature bag filter. The glass fiber membrane filter material produced by this technology has the advantages of low running resistance, long life, no film shedding, long-term working conditions of 260 degrees (instantaneous temperature up to 300oC), and all performances of the dust bag have no changes. The yield of dust below 5um is below 11.0 m. The service life of the dust bag will exceed 2 years.
The material used for the ptfe dust bag, the scientific name is polytetrafluoroethylene, the Chinese trade name is "Teflon", "Teflon", "Teflon", "Teflon" and so on. Polytetrafluoroethylene is known as the "Plastic King". It is a polymer compound formed by the polymerization of tetrafluoroethylene. It can withstand all chemicals except molten alkali metal, chlorine trifluoride, chlorine pentafluoride and liquid fluorine. The boiling remains unchanged, and it is widely used in various occasions that require resistance to acids, alkalis and organic solvents. ptfe cloth bag has airtightness, high lubricity, non-adhesion, electrical insulation and good anti-aging ability, and excellent temperature resistance (it can work for a long time at a temperature of plus 250 to minus 180). Teflon itself is not toxic to humans. Operating temperature -190~250, allowing rapid cold and hot or alternate operation of cold and heat. Pressure -0.1~6.4Mpa.
1) Excellent temperature resistance, reaching 280 degrees.
2) Due to the special molecular structure of PTFE material, it has excellent chemical stability and corrosion resistance, which can improve the chemical erosion of the filter material.
3) Due to the non-sticky, water-repellent and non-flammable characteristics of PTFE fiber materials, this type of fiber becomes the most excellent filter material.
4) This kind of fiber is used as the base cloth, and the strength is basically guaranteed not to be attenuated during long-term use
Fiber shape: Because of the different spinning methods, the fiber color is divided into white and brown. The white fiber is relatively pure, and the fiber shape is mostly flat, while the brown fiber contains a small amount of impurities, and the fiber shape is mostly round.
The C-C bond is covered by the F atom in the PTFE molecule, and the C-F bond has a high and extremely stable bond. It is not corroded by any chemicals except for alkali metals and fluorine.
