PTFE coated needle felt dust bag is chemically stable and is characterized by a continuous operating temperature of over 250°C and an instantaneous temperature of up to 280°C; it is not afraid of acid, alkali and oxidation, and is almost Combustible; non-aging fiber; meets harsh working conditions and has a long life of more than 4 years. Pure PTFE coated needle felt dust bags are mainly used in chemical industry, waste incineration, temperature-resistant liquid filtration, etc., and maintain good chemical stability under various complex working conditions.
ptfe coated filter clothThe surface is covered with expanded material Polytetrafluoroethylene (ePTFE) microporous film has a pore size as small as 1 to 2 μm. The base can be needle-punched felt or woven fabric made of PTFE fiber, glass fiber (GF), etc. After the filter material is coated, the equivalent pore size becomes smaller, so there is no need to form a dust layer. It can achieve a good dust capture effect by relying only on its own dust collection function. At the same time, it can control dust from entering the depth of the filter material to prevent the filter material from being blocked. In addition, the dynamic friction coefficient on the surface of the film-coated filter material is reduced, which improves the dust cleaning performance. The filter material membrane helps to improve its own hydrophobicity and prevents the filter bag from scaling due to condensation on the filter material.
PTFE coated filter clothIt has hepa and ulpa grade filtration efficiency, low wind resistance and low energy consumption, small and uniform pore size, and dust interception The efficiency is high, reaching more than 99.9995%, and the porosity is as high as more than 85%. The porosity is high, and it also has a good interception effect under high air permeability.
