Description: In the field of dust bag, usually bag likened to the heart of bag filter, bag filter can handle what kind of dust-laden flue gas, mainly depends on the conditions of the chemical fiberused to make the bag itself. The general condition of the flue gas temperature, only need to bagresistance temperature of 150 ° C or below, these occasions, polyester, polypropylene, acrylic,nylon, chemical fiber basic competence. Occasions for the flue gas temperature is relatively high,such as: chemical, carbon black (silica) exhaust, ironworks blast furnace gas, cement plant shaft kiln exhaust, calcium carbide factory furnace exhaust, foundry, steel plant flue gas, asphaltconcrete stirring asphalt fumes, a firebrick furnace flue gas, coking flue gas, these dust flue gasdust due to the the resistor limits is not suitable for electrostatic precipitator collection, can only becollected with a bag or other means; For the dust-containing flue gas temperature down to 150 ° Cor less, higher investment or live venue constraints; Third, because dust in the flue gas, becausethe sulfur-containing components, dust flue acid "dew point" containing cloud of dust gas can onlybe above the acid dew point, a state of higher temperature was separated by filtration, and other factors, so that a need for a chemical fibers can withstand a higher temperature used to make filter medium. Fiber production companies to use advanced DuPont Teijin Fiber Co., Ltd. METAMAX (US-Tasman), adopts the international advanced standard US-Tasman high temperature filter needle felt, with the introduction of advanced equipment manufacturing production. Note: 1, needle punched filter felt in the United States and the Tasman high temperature performance test table,see Schedule 2, US-Tasman U.S. company DuPont Nomex (NOMEX) and Teijin produced CognexAlex (CONEX) collectively. 3 sewing US-Tasman filter bags, must be dedicated sewing thread. I usePTFE sewing thread sewn filter bags, high strength, wear resistance, heat resistance up to 260 ℃.
