PPS high temperature, acid acupuncture: PPS high temperature, acid needle punched filter felt is used with DuPont Teijin company produces enzymes polyphenylene sulfide chemical fiber, high temperature needle felt by other manufacturing processes production of new high-temperature filter material, PPS fiber has strength and maintain the integrity inherent chemical resistance in harsh environment to maintain good filter performance, and achieve the desired life, PPS applications in the following cases the performance representing excellence. 1, the working temperature of 190 ℃, instant 232 ℃, limiting oxygen index of 34-35. 2, the oxygen content of 15% or less of the occasion. 3, flue gas containing sulfur oxides. 4, with a wet flue gas dust. PPS needle felt dust bag dust bag is usually likened to the main components of baghouse, baghouse dust can handle what kind of gas, mainly also depends on the chemical used to manufacture fiber dust bag their own conditions. General flue gas temperatures, dust filter bag only resistant to a temperature below 150 ℃, these occasions, polyester, polypropylene, acrylic, nylon and other chemical fibers can basically do the job. As for the flue gas temperature is relatively high occasions, such as: chemical, carbon black (white carbon black) exhaust, ironworks blast furnace gas, cement kiln exhaust gas, calcium carbide furnace exhaust factory, foundry, steel flue gas, asphalt concrete mixing asphalt fumes, smoke brick kilns, coke gas, etc., first, because these dusty flue dust resistivity due to restriction not suitable for electrostatic precipitator collection, only with collection bag or other means; The second is for the dust flue gas temperature drops below 150 ℃ or higher investments by site venues; Third, because the dust because of the flue gas containing sulfur ingredients, dust flue gas with acid "dew point" with gas cloud of dust only in the acid dew point temperature is higher than that performed in a state separated by filtration and other factors, so you need to have a higher temperature can withstand high-temperature corrosion-resistant dust bag PPS chemical fibers used to make high-temperature bag dust filter.
