Dust  filter bag is a kind of efficient dust  filter material, the main function is to help the dust collector efficiently capture the dust particles in the dust containing gas. Products are mainly used in thermal power generation, building materials, steel, waste incineration, chemical, glass and other industries, but in the face of different dust collectors, dust filter bag materials are not the same, so what are the common dust filter bag materials?

1, PPS: PPS fiber (polyphenylene sulfide) by three-dimensional needling of a filter material, can be used at about 160℃ for a long time. PPS fiber, also known as polyphenylene sulfide fiber, because of its special molecular structure, and has good chemical stability and strength complete maintain characteristics, the effect is particularly prominent in the high sulfur flue gas environment, suitable for coal-fired boilers, electricity, waste incineration and other high acid flue gas filtration environment;

2,P84: using P84 fiber three-dimensional needling,P84 fiber (namely polyimide fiber) has good high temperature resistance, high temperature resistance up to 260℃, and P84 fiber cross section is not specification foliate, can greatly improve the filtering effect. Fiber itself also has a certain degree of hydrolysis resistance, oxidation resistance. The product has good temperature resistance and good filtration effect, and is widely used in complex working conditions such as concrete mixing, cement, waste incineration and coal-fired boilers.

3, acrylic: with it as raw material made of felt by needling, after special water resistant treatment to get acrylic medium temperature anti-hydrolysis needling filter felt. Breathable capacity 14M3/M2·min@200Pa, instant working temperature 140℃, normal working temperature 120℃. The acrylic woven fabric is used as the base to enhance the horizontal and horizontal strength of the needle felt. With excellent chemical resistance and hydrolysis resistance, it is widely used in the dust collection of asphalt, dryer, coal mill, power plant sintering machine and other flue gas.

4, aramid: long-term temperature resistance 204℃, instant temperature resistance 240℃, alkali resistance is very strong, acid resistance medium, is a good material for processing 180~220℃ high temperature gas. Aramid needle filter material, widely used in steel, cement, electric power, chemical and other industries, is an ideal filter material for flue gas dust removal;

5, polyester: gram weight 500g/m2 breathable capacity 8~12m3/m2.min wool rolling steel, metallurgy, machinery, non-ferrous smelting, coking refractory, cement building materials, chemical industry, food, medicine, environmental protection equipment and other industries nbsp; Thickness 1.8mm operating temperature Operating temperature :120℃ Instant temperature :150℃;

6, PTFE: The use of PTFE(polytetrafluoroethylene fiber) by three-dimensional acupuncture and a filter material. PTFE fiber is a macromolecular linear structure, so it has strong temperature resistance, wear resistance, corrosion resistance, chemical resistance stability, widely used in steel, electric power, waste incineration and other bad flue gas filtration environment;
