Filter bags are one of the keys to baghouses so there are several factors to consider before choosing a filter bag:
▲ Temperature
▲ Humidity
▲ Chemical composition
▲ Flammability and Explosion
Introduction to material of filter bags:
▲POLYESTER(PE) : Maximum continuous use temperature at 135 ° C, up to 150 ° C, for general fine dust, smoke collection.
▲ARAMID(NOMEX) : The maximum continuous use temperature is 204 ° C and the highest is 220 ° C. It is used in asphalt mixing plants, lime powder factories and ceramic factories. It has good wear resistance along with acid and alkali resistance.
▲PPS(RYTON) : The maximum continuous use temperature is 190 ° C and the highest is 200 ° C, commonly used in coal-fired boilers, kiln, chemical drying flue gas dust removal, cement plants, power plants and chemical plants.
▲FIBER GLASS : High temperature resistance 260-280 °C, high efficiency of dust removal with expanded yarn. Besides, PTFE COATING enhances chemical resistance, commonly used in steel plants, coal-fired boilers, kiln, chemical drying flue gas dust removal, cement plants, power plants, chemical plants and smelting .
▲TEFLON(PTFE) : High temperature resistance of 260-280 ° C with excellent acid and alkali resistance, long service life, good resistance to hydrolysis and flame retardant, commonly used in steel plants, coal-fired boilers, kiln, chemical drying flue gas dust removal, cement plants, power plants , chemical plants and smelting.
Disposition of filter bags:
▲ PTFE MEMBRANE:The film is made of PTFE (polytetrafluoroethylene) and all kinds of ultra-fine dust can be used for dust removal. The smooth surface can reduce the adhesion of fine dust. The ultra-fine dust particles can be separated to the surface of the filter bag without penetrating inside in order to achieve the minimum discharge standard.
▲ PTFE MEMBRANE: The film is made of PTFE(polytetrafluoroethylene) and all kinds of ultra-fine dust can be used for dust removal. The smooth surface can reduce the adhesion of fine dust. The ultra-fine dust particles can be separated to the surface of the filter bag without penetrating inside in order to achieve the minimum discharge standard.
▲ PTFE COATING: Improve filtration accuracy and increase the acid and alkali resistance of the filter bag.
▲ Oil-proof and Splash-proof: It can prevent and reduce the adhesion of wet smoke dust to the filter bag.
▲ Singe calendaring: After the surface of the filter material is calendared or singed, it not only improves the cleaning effect, but also improves the high precision and low dropout performance of the filter bag.
