In the face of biomass boiler flue gas containing moisture and potassium, it prevents filter bag caking with its low moisture absorption rate and dimensional stability, maintaining a constant permeability; the exhaust purification system of large diesel generator sets uses PPS bags, which can withstand high-temperature pulsations and *** salt particles, reducing PM2.5 emissions; in pharmaceutical spray drying towers, it also recovers high-value pharmaceutical powders with food-grade surface smoothness, ensuring both filtration accuracy and resource recycling.
Polysulfone (PPS) is a high-performance synthetic fiber with excellent heat resistance, capable of operating in high temperatures for extended periods without aging. Its melting point is approximately 285 degrees Celsius, and continuous use temperature can reach around 190 degrees Celsius. PPS material exhibits good resistance to most acids, bases, and organic solvents, and is not easily corroded. In terms of mechanical strength, PPS fibers have high tensile strength and wear resistance, making them suitable for use in high-speed airflow environments. These properties enable PPS bags to maintain a longer service life under complex industrial conditions.
