PTFE polytetrafluoroethylene needle punching is a filter material made by three-dimensional needle punching of PTFE (polytetrafluoroethylene fiber). The product has good temperature resistance, wear resistance, corrosion resistance, chemical resistance, high filtration efficiency, low operating resistance, and long service life. It is widely used in various harsh flue gas filtration environments such as steel, electricity, and garbage incineration.

PTFE needle felt filter bags have good chemical and physical properties and are widely used in harsh working conditions such as electricity, waste incineration, municipal waste dust collection, chemical dust removal, etc. PTFE coated needle felt filter bags are ideal for waste incineration. Dust bag.
1) PTFE needle felt filter bag is made of PTFE fiber + PTFE base cloth, without adding any raw materials and additives, and does not change the original characteristics of PTFE. The product has good temperature resistance, wear resistance and chemical resistance. It has high filtration efficiency, low operating resistance and long service life.
2) PTFE coated needle felt filter bags are made of PTFE microporous film that is laminated with needle felt and film through a special thermal coating process. It has a smooth surface, high dust peeling strength, easy dust removal, and a filtration efficiency of up to 99.99 %, and the product has good chemical stability and corrosion resistance.

Advantage

1. Remarkable dust removal efficiency
PTFE coated needle felt filter bag is made by laminating PTFE microporous film with needle felt and film through a special thermal coating process. It has a smooth surface, high dust peeling strength, easy dust removal, and a filtration efficiency of up to 99.99%. Greatly exceeds the national standard 2. Wide adaptability to the use environment
PTFE needle felt filter bag has good temperature resistance, wear resistance and chemical resistance, and has good adaptability to temperature, humidity and corrosive gases, especially for gases with high concentration, high humidity and fine particle dust. Better results. These are incomparable to ordinary filter materials.

3. Good breathability
The air permeability of PTFE needle felt filter bag can reach 3-6m3/m2.min, which exceeds the requirements of actual use.
4. Good economic benefits
The extremely strong chemical and physical properties of PTFE needle felt filter bags enable the product service life to be as long as 3-4 years under normal working conditions. More valuable dust can be recovered, and the economic benefits can be imagined.
