At present, most of the aramid fibers used in the domestic high-temperature filtration field are meta-aramid fibers (aramid 1313) and aramid sulfone fibers. Yantai Taihe), etc., the supply of raw materials is sufficient, and it is an ideal fiber raw material for various high-temperature filter materials (including long-filament filter cloth, long and short-filament interwoven filter cloth, short fiber filter cloth, acupuncture filter cloth, etc.). Fiber Oxygen Index can be unnatural at 29%. When the temperature is above 400°C, the fibers are slowly carbonized.
Aramid Metas dust bag can operate continuously at a temperature of 204°C (instantaneous temperature of 250°C) and can withstand repeated instantaneous temperature fluctuations of 250°C. At the same time, it has excellent dimensional stability. Therefore, the thermal shrinkage rate of 1% has excellent high temperature stability. Good chemical resistance at low concentrations of acid and alkali and most hydrocarbons will not affect it, even a small amount of fluoride will not corrode it significantly. Metas filter materials have been proven to be widely used in high-temperature filtration fields, and can maintain high strength and high wear resistance for long-term use. In addition, Metas fiber also has good dimensional stability. Compared with glass fiber, its wear resistance and folding resistance are unmatched by glass fiber. Therefore, it has high temperature resistance and long service life, and is the preferred filter material for bag filter in high temperature filtration occasions.
Post-processing methods: singeing and calendering, high temperature setting, water and oil repellency, antistatic, PTFE coating, emulsion dipping, surface coating
1.Avoid using in acidic and humid environments;
2.Pay attention to save and use in low light conditions;
3.Pay attention to control the content of O2 and oxidizing substances in the filtered gas.
