PTFE dust bag

5. PTFE dust bag PTFE needle felt is a filter material made of PTFE (polytetrafluoroethylene fiber) through three-dimensional acupuncture. PTFE fiber is a macromolecular linear structure, so it has strong temperature resistance, wear resistance, corrosion resistance and chemical stability. It is widely used in various harsh flue gas filtration environments such as steel, electric power and waste incineration.

fiber glass dust bag

 6. Glass fiber filter bag: This filter material is a high temperature resistant filter material with reasonable structure and good performance. It not only has the advantages of high temperature resistance, corrosion resistance, dimensional stability, extremely small elongation and contraction rate and high strength of Glass fiber weaving fabric, but also the felt fiber is single fiber, three-dimensional microporous structure, high porosity and low resistance to gas filtration. It is a high-speed, high-efficiency high-temperature filter material. Compared with other high temperature resistant chemical fiber felts, it has special advantages such as low price, low running resistance, high filtration precision and higher temperature resistance. It is suitable for high temperature flue gas filtration in steel, metallurgy, carbon black, power generation, cement, chemical and other industries.  Glass fiber needle felt, Gram weight 950g /m2, gas permeability 20-35m3/m2.min, (Teflon coating )power plant, submerged arc furnace, blast furnace gas and other carbon black occasions, thickness 3.0mm, use temperature 90 ~ 280℃

7. The film bag: above the various material filter bags can provide the corresponding film filter bag. PTFE microporous membrane can effectively filter dust of 2.5um particle size, which is the first choice for solving PM2.5, and is also an important way to ensure the discharge concentration of various working conditions is below 10mg/Nm3. Our company cooperates with domestic well-known PTFE microporous membrane manufacturers to develop and produce various kinds of membrane filter bags selecting high-permeability and low-resistance three-dimensional microporous membranes to meet customers’ ultra-clean emissions.

 Anti-static dust bag

8. Anti-static dust bag: anti-static dust cloth bag filter cloth are made of anti-static terylene needle felt, with excellent anti-static properties, used for flour dust, chemical dust, coal dust industry, etc. in case of electrostatic discharge may explode. It is currently the most ideal choice for explosion-proof dust collection. Industrial dust can easily cause explosions and fires when the concentration reaches a certain level (ie, the explosion limit), such as electrostatic discharge sparks or external ignition. Such as: flour dust, chemical dust, coal dust, etc., in case of electrostatic discharge, there is a possibility of explosion. In the field of bag dust removal, if the dust needs to be collected by a cloth bag, it is required that the filter material of the needle felt antistatic dust collector has antistatic property. Our company absorbs and digests foreign technology and develops and produces permanent anti-static needle-punched filter felt according to the domestic blast furnace gas coal mill dust collection and cement plant coal mill dust collection and other industries’ requirement.
