Description
Technical field:
The present invention relates to a kind of filtrate, particularly relate to a kind of novel high-efficiency, long life and high temperature resistant filtering material.
Background technology:
Common employed filtrate brute force differs, not folding or non-refractory, the easy bonding in surface dust in behaviour's process, also there are the displacement wearing and tearing, thus, make the service life of made filter bag short, filter efficiency greatly reduces, can not normally filter under the hot environment, the used energy consumption of deashing blowback is big, and has increased use cost greatly.
Summary of the invention:
The objective of the invention is to provide a kind of improved novel high-efficiency, long life and high temperature resistant filtering material, it not only can make made filter bag can prevent dust bonding effectively, anti-folding, anti-oxidant, wear-resisting, high temperature resistant, and acid and alkali-resistance, the displacement wearing and tearing are eliminated in not hydrolysis, and,
Moving dedusting reverse gas cleaning power consumption is little, long service life.
The present invention proposes following design to achieve the above object: novel high-efficiency, long life and high temperature resistant filtering material of the present invention comprises warp fiber line and weft fiber line, and Knitting is made into filtrate cloth, described warp fiber line is twisted as the Shu Ercheng single by the glass fibre assembly, described weft fiber line is twisted into single by polytetrafluoroethylene fibre bundle and glass fiber bundle, the glass fiber bundle of described warp fiber line, the radical of every bundle glass fibre is 60～600, every fibre diameter is 6～9 μ m, the polytetrafluoroethylene fibre bundle of described weft fiber line, the radical of every bundle polytetrafluoroethylene fibre is 150～400, every fiber is more than 10 dawn, the glass fiber bundle of described weft fiber line, the radical of every bundle glass fibre is 60～300, every fibre diameter is 6～9 μ m, the warp-wise density of the filtrate cloth that described warp fiber line and weft fiber line Knitting are made into is 12～22 bundle/cm, latitudinal density is 12～22 bundle/cm, the warp-wise brute force is 1000～4500N/2.5cm, the broadwise brute force is 1000～4000N/2.5cm, is covered with a polytetrafluoroethylmicroporous microporous membrane on the upper surface of the filtrate cloth that described warp fiber line and weft fiber line Knitting are made into.Described warp fiber line is that polytetrafluoroethylene fibre bundle and glass fiber bundle are twisted into single, the polytetrafluoroethylene fibre bundle of described warp fiber line, the radical of every bundle polytetrafluoroethylene fibre is 150～400, every fiber is more than 10 dawn, the glass fiber bundle of described warp fiber line, the radical of every bundle glass fibre is 60～300, and every fibre diameter is 6～9 μ m.
Because the present invention has improved existing novel high-efficiency, long life and high temperature resistant filtering material, employing is pieced together the warp fiber line that is twisted as Shu Ercheng by glass fibre and is made into cloth with the weft fiber line Knitting that is twisted into by polytetrafluoroethylene fibre bundle and glass fiber bundle, or adopt warp fiber line that is twisted into by polytetrafluoroethylene fibre bundle and glass fiber bundle and the weft fiber line Knitting that is twisted into by polytetrafluoroethylene fibre bundle and glass fiber bundle to be made into cloth, and also on cloth, be covered with a polytetrafluoroethylmicroporous microporous membrane, folding again that filtrate of the present invention is high temperature resistant, high temperature resistant reaching about 260 ℃, folding number is brought up to 80～1,000,000 times by original 30,000 times, described polytetrafluoroethylmicroporous microporous membrane has smooth surface can not adhere to dust, even ultra-fine moist dust can not adhere to yet, dust can not be penetrated into filtrate inside, dust peeling property can be very good, easy deashing, realize surface filtration, ultrafine dust had good filterability, filter efficiency can reach 99.9%～99.999%, the polytetrafluoroethylmicroporous microporous membrane laminar surface is hydrophobic also, resistive connection reveals, be applicable to high humidity gas, in addition, there are not the displacement wearing and tearing, adopt pulse jetting deashing, save the Compressed Gas cost, and the deashing frequency is low, filtration Shi Final is under the lower resistance and moves, operation energy consumption descends significantly, and economic operating cost.The present invention is suitable for making the filter bag use of all kinds of sack cleaners.
