PTFE high-temperature resistant dust removal filter bag, polytetrafluoroethylene (fluoroethylene) fiber, specific gravity of 2.2 g/cm3, melting point of 327℃, decomposition temperature of about 415℃, has *** chemical corrosion resistance, and is resistant to all chemicals. Corrosion, known as the king of plastics. Polytetrafluoroethylene (PTFE) has a macromolecular linear structure. In its molecular structure, the fluorine atom is larger than the hydrogen atom, and the binding force of the fluorocarbon bond is also strong, which plays a role in protecting the entire carbon-carbon main chain, making the PTFE fiber has excellent chemical stability, low friction coefficient, non-combustible, can withstand strong corrosive reagents or solvents such as strong acids, strong alkali, and strong oxidants, and has excellent properties such as high and low temperatures. The long-term use temperature is-200 to 260 ℃. The continuous working temperature of the PTFE filter bag is above 250 degrees, and the instantaneous temperature is 280 degrees. It is completely not afraid of acid, alkali and oxidation, and is almost non-flammable. Longitudinal and transverse elongation (200N/5cm)<5%; heat shrinkage; 150 degC, 90 min2%; burst strength; >300 N/cm2. The filter material is post-processed by PTFE impregnation, PTFE coating, and film-coating. PTFE high temperature dust removal filter bags are widely used in metallurgy, electricity, waste incineration, steel, asphalt mixing stations. chemical industries. Cement, aluminum processing, high-sulfur coal dust removal and other fields.
