Our company selects NOMEX produced by DuPont, Teijin''s CONEX high temperature resistant fiber, adopts international advanced standard, and adopts advanced high temperature resistant needle felt filter felt.
Aramid high temperature resistant needle felt filter features:
1. Excellent temperature resistance: continuous operation at 204 ° C (instantaneous temperature 250 ° C), and can withstand repeated 250 ° C instantaneous fluctuation temperature.
2. Outstanding dimensional stability: only less than 1% heat shrinkage at 250 ° C, with excellent high temperature stability.
3. Proud fire resistance: Decomposition and carbonization start at 400 °C. The limiting oxygen index (LOI) is 30. It does not ignite or support combustion.
4. Good chemical resistance: acid and low concentrations of hydrocarbons, most of it does not affect, even a small amount of fluoride is not significantly etching;
Application:
Specific application areas: chemical, carbon black (white carbon black) tail gas, ironmaking plant blast furnace gas, cement plant shaft kiln exhaust gas, calcium carbide plant kiln exhaust, casting, steel mill flue gas, asphalt concrete mixing asphalt flue gas, refractory brick Kiln flue gas, coking flue gas.
