Polyester needle punched filter feltrnPolyester needle felt is the most versatile, most cost effective and most widely used filter medium for dust collection. It is strong, abrasion resistant, can work up to 150u00b0C and has good resistance to common acids, solvents and oxidising agents.rnrnP84 (polyimide) needle feltrnP84 polyimide needle felts are excellent high temperature filter media in terms of performance, generally surpassing the other standard media with the exception of PTFE.rnrnPPS needle-punched filter feltrnPPS high temperature resistant needle-punched filter felt PPS fiber can keep intensity completely and bear chemistry naturing inherently, keep good filtration performance among the abominable environment, reach ideal service life. In coal boiler, rubbish incinerator, power plant of fly ash filtering of pulse clear dust catcher, PPS filter felts are an ideal filtration material. PPS filter felt is one of the main filter material able to bear the high temperature according to processed of production technology and artificial material of other high-temperature filter felt.rnrnMetamax needle felt(Nomex felt)rnMetamax is the mixture of 95% m-aramid and 5% p-aramid. Metamax needle felt is meta-aramid fiber invented and manufactured by Heading Filter. NOMEX fibers are from the generic fiber group called meta-aramid. Another brand name from this fiber group is CONEX and NOMEX. rnrnAcrylic needle feltrnNormally in filtration acrylic refers to homopolymer acrylic which is essentially made from 100% of acrylonitrile. Homopolymer acrylic needle felt and filter bags for industrial filtration. This kind of needle felt is with good ability of acid and alkali resistance, anti-oxidation, hydrolysis resistance. It suits middle temperature and high acid, alkali chroma environment. It is widely used in metallurgy, chemical, building material, electric power station, mechanism industry, petroleum, medicine, printing and dyeing, food and beverage, and other industries to filter gas and recycle material.rnrnPTFE needle punched feltrnPTFE needle punched felt are produced from 100% PTFE fiber which has been punched in three-dimensional structure. They have excellent features such as excellent flexibility, molding capability, high tensile strength, creep resistance, high and low temperature resistance, corrosion resistance and anti-aging. 100% PTFE filter material can meet requirements in hostile environments of temperature fluctuating and acid & alkali in all PH range. The lifespan of PTFE filter material will be guaranteed for over 4 years as long as the temperature is controlled under the maximum operating temperature.rnrnPP needle punched feltrnPolypropylene is a relatively low temperature fiber with quite excellent chemical resistance which finds use in specialist applications such as the chemical industry.rnThe fibers cannot hydrolyze, the only chemical weakness being a susceptibility to oxidizing agents. Other than that they can be used almost universally provided the temperature is below 90u00b0C.The fiber is of a low density (it floats in water) and so a given denier of fiber is much larger in diameter than the polyester equivalent. This leads to felts being quite thick, almost 50% thicker than for the same polyester weight.The fiber is very prone to static build up so the felts are often augmented by the incorporation of either conductive fibers or a conductive scrim or a combination of the two. This then helps to dissipate potential static electric discharges.
P84 rn- Excellent steady under high temperature and resistance to acidrn- P84 can operate continuously, under practical and low acid working conditions, at temperatures up to 500.rn- High filtration efficiency, high tensile strength.rn- The complex cross sectional shapes create 30-90% more collection surface area when compared to round or oval shaped fibers.rn- Low back washing pressure, maximum flexibilityrn- The unique trilobal fiber structure of P84 provides customers with high efficiency filtration, low pressure drop, and reduced cleaning energy.rn- Excellent dust cake releasern- P84 has irregular, trilobal fibers that provide better collection efficiencies and enhanced dust cake release properties.rnrnPPSrn- Exceptional Stability for a Wide Range of Temperature and Frequency Variationsrn- Be suitable for the oxygen content below 15%;rn- Chemical Resistance to Acids, Alkali and Organic Solventsrn- Containing moisture in the flue gas; Hydrolysis Resistancern- Very stable in finished felt form with stability standards at 2% shrink or stretch.rn- Favorable temperature resistance melting point 285, limited oxygen index 34~35;rnrnNomexrn- Due to its high thermostable performance, it is able to perform well for a long period of time under acid base in 204;rn- Chemical Resistance to weak Acids, weak Alkali and Organic Solventsrn- Its high performance in its thermal stability and low contraction performance, guaranteed the end product filter pocket size remain stable, the avoidance of bag cage broken phenomenon;rn- Its high performance regarding its wearability and the folding endurance make it the perfect product for many kinds of dust structure and the dust quantity. This also helps in extending the filter material's service life.rn- High resistance to breakage and its high break elongation ratio guaranteed the end product of filter materials with high intensity, good product longevity, and better tolerance to injection;rn- Metamax is easy to process with low waste and it is compatible to most machines. This enhances its processing efficiency and reduces cost.rn- Perfect combination of performance with price - high performance to price ratiorn- Its high performance in ventilation reduces the dropping of dust removal system pressure and thus save the energy and its related cost.rn- It is flame resistant with self-extinguish nature and non-melt drop.
