PTFE coated dust bag

     Filtration mechanism of polyester-coated needle felt felt dust bag: the mechanism of film surface filtration is the same as that of dust layer filtration, mainly by microporous screening. Because the pore size of the membrane is very small, a large part of the dust particles can be retained on the surface of the membrane to complete the gas-solid separation process. This process is different from the general filter material separation process, the dust does not penetrate into the fiber supporting the filter material.

     The advantage is that: at the beginning of working in the filter bag, it can form a thin layer of dust with good ventilation on the membrane surface, that is, higher dust removal efficiency and lower running resistance. PTFE film dust filter bag filter material scientific name PTFE, is the _PTFE needle felt felt dust filter bag put on the market in 2005, it is a unique material, continuous operation at 250 ℃, instant 280 ℃ conditions It can resist acid and alkali corrosion in all PH range. . The filter material of the PTFE needle felt felt dust filter bag is self-lubricating_, does not absorb moisture, and can withstand ultraviolet radiation. And it has outstanding heat resistance, cold resistance and friction resistance, and does not age. At present, it is a __ dust filter bag filter material, with _ comprehensive advantages.

     The PTFE membrane is used for the outer wall material of the "Water Cube" in the Beijing Olympic venues, which shows its excellent characteristics. PTFE membrane dust-removing filter bags are becoming more and more common in dust-removing cloth bag applications due to their excellent characteristics. The surface filtering effect is high. Generally, the industrial filter material is uncoated. It relies on the surface of the filter material to establish a dust layer for effective filtration. The effective filtration time is long (about 10% of the entire filtration process), high resistance, low efficiency, and retention Incomplete, high loss, high filtration and backflushing pressure, frequent dust cleaning, high energy consumption, short service life, and large equipment area. Use the membrane dust-removing cloth bag, the dust cannot penetrate into the filter material, only the surface is filtered, whether it is thick or fine dust, all deposited on the surface of the filter material, that is, the filter material is retained by the pore size of the membrane itself, there is no initial filtration period, starting _ is effective filtration, The time near _ is in the filter.
