PPS bags are made primarily from Polyphenylene Sulfide (PPS) fibers and are manufactured through processes like three-dimensional needling, resulting in high-performance dust-filter bags with the following outstanding features:
Excellent high-temperature performance
Continuous operating temperature typically reaches 160°C, with instantaneous temperature resistance up to 190°C, suitable for medium to high-temperature flue gas environments in coal-fired boilers, waste incineration, etc.
High chemical corrosion resistance
Excellent stability against corrosive gases such as sulfur oxides (SOx, SOy), acids, and bases; commonly used in power plant desulfurization, chemical industry, metallurgy, and other sectors.
High filtration efficiency
The fiber structure is dense, with a surface that can be coated for treatment, achieving a filtration accuracy of over 99.99%, suitable for ***emission requirements.
High mechanical strength, good dimensional stability
Maintains structural integrity in high-speed airflow and dust erosion environments, is not prone to deformation or damage.
5. Easy-to-clean, long-lasting
Smooth surface, excellent dust stripping properties; when used in conjunction with the pulse cleaning system, can extend service life to over 3 years.
6. Optional composite form
PPS+PTFE composite filter bags, further enhancing oxidation resistance, water resistance, and condensation prevention, suitable for more complex operating conditions.
In summary,PPS bags are an ideal dust removal material for high-temperature, high-corrosion, and high-filtering precision conditions, widely used in industries such as power, steel, cement, and waste incineration.
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 environments with high-speed airflow. These properties enable PPS bags to maintain a longer service life under complex industrial conditions.
