Factory supply resistance to strong acid hepa air filter

Features of hepa air filter

         Aramid has excellent heat resistance, flame resistance, high temperature dimensional stability. 

Particularly conspicuous is its excellent mechanical properties, strength and polyester similar to, wear resistance, 

good resistance to bending and has excellent characteristics of textile processing, can acupuncture into spun lace 

non-woven fabric. Aramid fiber 1313 at different temperatures, strong retention rates at different times, 

including in the dry heat temperature of 250 C for 1000 hours under the conditions of its strength retention up to 60%. 

Aramid fiber 1313 as a functional fiber in high temperature dust filtration industry has an irreplaceable status, 

but because of the characteristics of molecular structure determines, it has some defects. Such as poor resistance to 

strong acid, high temperature hydrolysis is poor, not in the coal-fired boilers, waste incineration and other industry 

applications.

Application factories of this bag: 

Chemicals factory, carbon black plant, ironworks blast furnace, cement kiln, calcium carbide 

furnace, foundry steel plant, asphalt concrete mix asphalt smoke treatment, brick kiln flue gas, coking gas.
