Metas needle punched felt can be used204℃Continuous operation at a certain temperature (instantaneous temperature)250℃）And can withstand repeated250℃Instantaneous temperature fluctuations, coupled with outstanding dimensional stability performance, in250℃At a temperature lower than1%Thermal shrinkage rate,Has excellent high-temperature stability. Good chemical resistance does not affect it at low concentrations of acids, bases, and most hydrocarbons, and even small amounts of fluoride do not significantly corrode it. Metas filter materials have been proven to be widely used in the field of high-temperature filtration, and long-term use can maintain high strength and wear resistance. Widely used in industries such as asphalt, cement, steel, non-ferrous metals, lime, dust, metallurgy, drying, crushed stone, gypsum, plastics, carbon black, coke, shipbuilding, tobacco, etc.
