The professional dust removal bag for asphalt mixing plant should have the following characteristics:

1. Excellent temperature resistance: it can operate continuously at a temperature of 204 °C (instantaneous temperature of 240 °C), and can withstand repeated instantaneous fluctuations of 240 °C.
2. Excellent dimensional stability: the thermal shrinkage rate is less than 1% at the temperature of 204℃, and it has excellent high temperature stability.
3. Outstanding fire resistance: it starts to decompose and carbonize at 400 ℃, the limiting oxygen index (LOI) is 30, and it does not spontaneously ignite or support combustion.
4.good chemical resistance: low concentration of acid and alkali and most hydrocarbons will not affect it, even a small amount of fluoride will not significantly corrode;

The NOMEX filter bag can operate continuously at a temperature of 204°C (instantaneous temperature 250°C) and can withstand repeated instantaneous temperature fluctuations of 250°C, and at the same time has excellent dimensional stability. It only has a thermal shrinkage rate of less than 1% and 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.
