Glass fiber felt used in high temperature filter bag

Glass fiber (Fiberglass) is an inorganic non-metallic material with excellent performance. There are many kinds. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength.

Glass fiber can be made into glass fiber needle felt by needle punching non-woven equipment. Ordinary glass fiber felt can be used as the base cloth of high temperature filter bag or airgel felt.

Glass fiber filter bag needle felt is composited with glass fiber fabric by needle punching process. It is an ideal filter material for high temperature, medium temperature, low temperature and high humidity. It is sewn into filter bags of various specifications.

It can be used for a long time at a high temperature of 240°C, and the short-term temperature resistance can reach 280°C. It is widely used in high-temperature flue gas filtration in steel, cement, electric power, non-ferrous metals, waste incineration, asphalt concrete mixing, and chemical industries. It is suitable for pulse and high-speed reaction Blowing dust removal method is the most widely used filter material for high temperature bag filter.

Aerogel, also known as air gel, solid smoke or blue smoke, is a super heat insulation material with nanoporous network structure, and it is a revolution of traditional heat insulation materials in many fields such as aerospace, military industry, petrochemical, electric power, metallurgy, construction, clothing, etc. Sexual alternative products, with the lowest density of solids, the lowest thermal conductivity, the highest acoustic impedance, etc.

Nano-airgel thermal insulation blanket is a kind of flexible airgel thermal insulation blanket that composites airgel in a flexible substrate through a special process. Suitable for high temperature applications up to 650°C. The thermal insulation performance is more than 5 times that of traditional thermal insulation products, Class A (smoke-free), non-combustible, environmentally friendly, flexible and easy to install.

• Wider and higher operating temperature range

  
  

• -200℃~+650℃, excellent performance in hot and humid environment up to 650ºC.

  
  

• Thermal insulation performance is 5 times that of traditional thermal insulation products

  
  

• Low thermal conductivity, at room temperature: about 0.02 w/(m*k), even lower than air thermal conductivity.

  
  

• More and wider space utilization

  
  

• Due to the low thermal conductivity, the same thermal insulation effect can be achieved with a thinner thermal insulation thickness, and the general installation thickness is about 80% thinner than traditional thermal insulation products.

  
  

• Non-combustible (smoke-free), Class A

  
  

• The combustion performance level meets the requirements of the combustion performance level specified in GB8624-2012, and it is class A fireproof.
