PTFE (polytetrafluoroethylene) membrane coated needle felt filter bag

So far, it is a fiber with good chemical resistance that can be found all over the world. It can withstand the oxidation corrosion of various strong oxides and the problem of no hydrolysis reaction at all. PTFE (polytetrafluoroethylene) has good filtration efficiency and good dust removal performance. Even at high temperature, only a small amount of dust adheres to the surface. Our company uses the excellent performance of PTFE (polytetrafluoroethylene) fiber and processes the PTFE (polytetrafluoroethylene) coated needle felt filter material through excellent production technology to become a new filter material with high performance and high cost performance.
PTFE (polytetrafluoroethylene) needle felt membrane filter material has outstanding performance indicators due to its excellent material performance and the enhanced effect of production process. The main characteristics are summarized as "one low, one high and four good". The details are as follows:
(1) Low energy consumption
The filter material is made of high-strength PTFE (polytetrafluoroethylene) base cloth, and the surface is needle punched with PTFE (polytetrafluoroethylene) short fiber, with soft texture. Good jitter during ash removal, and the dust is easy to peel off; The required ash cleaning pressure is small and the ash cleaning times are few, which can effectively reduce the consumption of compressed air, reduce the amount of maintenance and save the operation cost.
(2) High filtering precision
PTFE (polytetrafluoroethylene) microporous membrane on the surface of PTFE (polytetrafluoroethylene) needle felt membrane filter bag has small and uniform pore diameter (0.10-2.0 μ m) , it can separate all dust larger than the micropore diameter, and has a very high capture rate for dust PM10 (respirable dust) and PM2.5 (respirable dust) that seriously damage human health. Therefore, the dust purification efficiency is high and stable, and it is easy to achieve less than 10mg / m ³ Emission standards.
(3) Good tensile strength and stability
The longitude and latitude strength of PTFE (polytetrafluoroethylene) needle felt membrane filter bag is 700n / 5 × More than 20cm, more suitable for making filter bags with large length and diameter (more than 6m long); After heat setting processing, the filter material basically maintains its original size at high temperature, which will not affect the gap between the filter bag and the skeleton, so as to ensure the filtering and ash removal effect.
(4) High operating temperature
PTFE (polytetrafluoroethylene) needle felt membrane filter bag can operate continuously from above the acid dew point to 240 ℃, and the instantaneous temperature resistance can reach 260 ℃.
(5) Good corrosion resistance
PTFE (polytetrafluoroethylene) needle felt membrane filter bag will not be oxidized by oxygen or nitride, so it is not necessary to consider the problem of high and low oxygen content in the dust collector. PTFE (polytetrafluoroethylene) material has outstanding corrosion resistance, and the filter material can resist the erosion of various acids, alkalis and other corrosive substances after PTFE (polytetrafluoroethylene) impregnation treatment. The base cloth of the filter bag is not eroded.
(6) Good oil and water repellency
Due to the performance characteristics of PTFE (polytetrafluoroethylene), the surface is smooth and the friction coefficient is low, which eliminates the adsorption of water by the filter material and effectively reduces the hardening phenomenon after condensation.
(7) Good comprehensive performance and wide application conditions
PTFE (polytetrafluoroethylene) needle felt membrane filter bag has excellent physical and chemical properties, so the use of the product is not affected by the change of fuel, and there are no strict requirements for the composition of chemical composition, volatile matter, moisture content, sulfur content, ash content, etc. in the fuel. It can fully meet the use requirements of various complex working conditions.
