The dust removal filter bag is an efficient dust removal filter material. The main function is to help the dust collector capture dust particles in the dusty 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, the materials of dust removal filter bags are not the same. So what are the common dust filter bag materials?

1. PPS: A filter material formed by PPS fiber (polybine sulfen ether) pierced through three -dimensional needle can be used for a long time at about 160 ° C temperature. PPS fiber is also known as polyophenyl sulfur fiber. Due to its special molecular structure, it has good chemical stability and intensity complete maintenance characteristics. It is particularly prominent in the effect of high sulfur -containing flue gas environment. It is suitable for coal -fired boilers. , Electricity, waste incineration and other high acidic flue gas filtration environment;

2. P84: It is made of p84 fiber three -dimensional needle. P84 fiber (that is, polyamide fiber) has a good high temperature resistance, high temperature resistance of 260 ° C, and P84 fiber cross section is non -specified leaf shape, which can greatly improve filtration filtration Effect. The fiber itself also has certain anti -hydrolysis and antioxidant. This product has good temperature resistance and good filtration effect. It is widely used in complex conditions such as concrete stirring, cement, waste incineration, and coal -fired boilers;

3. Acrylic: It is made of felt as a raw material through acupuncture, and it has been specially used to obtain the filtering of the Acrylic medium -temperature anti -hydrolysis needle. The breathable volume is 14m3/m2 · min@200Pa, the instant working temperature is 140 ° C, and the normal work is 120 ° C. Pamental felt with the Yayli machine as the base cloth to enhance the strength. It has excellent chemical resistance and hydrolysis resistance, and is widely used in the dust collection of flue gas such as asphalt, dryer, coal mill, and power plant sintering machine.

4. Aramid: Long -term temperature resistance of 204 ° C, instant temperature resistance of 240 ° C, strong alkali resistance, and medium acid resistance. It is a good material to treat high -temperature gases at 180 ~ 220 ° C. The aramid pest filter material, widely used in steel, cement, power, chemical industry and other industries, is an ideal flue gas dust removal filter material;

5. Polyester: 500g/m2 breathable volume of 500g/m2 8 ~ 12m3/m2.min burned coating, metallurgy, machinery, non -ferrous smelting, coking fire resistance, cement building materials, chemical, food, medicine, environmental protection equipment and other NBSP; thickness 1.8mm Temperature Work Temperature: 120 ℃ Instant temperature: 150 ℃;

6. PTFE: A filter material made of PTFE (polytetrafluoroethylene fiber) pierced by three -dimensional needle. PTFE fiber is a linear structure of macromolecules, so it has strong temperature resistance, abrasion resistance, corrosion resistance, chemical stability, and is widely suitable for various harsh flue gas filtration environments such as steel, power, and waste incineration;

7. The filter material of the glass fiber filter is a high -temperature filter material with reasonable structure and good performance. It not only has the advantages of glass fiber woven high temperature resistance, corrosion resistance, stable size, extremely small stabilization and shrinkage rate, high strength, but also fiber fiber fiber, three -dimensional micropore structure, high pore rate, small resistance to gas filtration resistance, less resistance to gas filtration resistance It is a high -speed and efficient high -temperature filter material. Compared with other high -temperature -resistant fiber felt, it has special advantages such as low price, low operating resistance, high filtration accuracy, and higher temperature resistance. Suitable for high -temperature flue filtering in steel, metallurgy, charcoal black, power generation, cement, chemical industry and other industries;

8. Anti -static dust removal bags: Filter cloths are made of anti -static polyester needle felt, which has excellent anti -static performance. It is used for dust, chemical dust, coal and dust. The ideal choice of explosion -proof and dust collection. After the concentration of industrial dust reaches a certain degree (that is, the explosion limit), if factors such as electrostatic discharge sparks or external ignition, can easily lead to explosion and fire. Such as: dust, chemical dust, coal dust, etc., are likely to explode in electrostatic discharge. In the field of bag dust removal, if these dusts need to be collected with cloth bags, the filter materials for making needle felt anti -static dust collectors are required to have anti -static performance. Our company absorbs and digests foreign technology, and develops and produces long -term anti -static needles according to the domestic blasts of gas grinding dust and cement planting dust and dust charging dust collection and other industries.

9. Filter bags above the coating bag can provide corresponding film filter bags. PTFE microre membrane can effectively remove the dust of 2.5um particle size, which is a solution to PM2.5 and an important way to ensure that the concentration of various operating conditions is under 10mg/nm3.

Different materials for dust removal filter bags are used in different working conditions and industries, which can not only help the dust collector well dust removal, but also use it for a longer period of use. Therefore Filter bag manufacturers maintain good communication and change the changes in working conditions at all times to facilitate timely adjusting the dust filter bag.
