PPS bags are high-performance dust filter bags made primarily from Polyphenylene Sulfide (PPS) fibers, produced through processes like three-dimensional needle-punching. They feature the following outstanding characteristics:
Excellent high-temperature resistance properties
Continuous operating temperature typically reaches 160°C, with instantaneous temperature resistance up to 190°C, suitable for coal-fired boilers, garbage incineration, and other medium to high-temperature flue gas environments.
2. Strong resistance to chemical corrosion
Exhibits excellent stability against corrosive gases such as sulfur oxides (SO2, SO3), acids, and bases, commonly used in power plant desulfurization, chemical industry, metallurgy, and other sectors.
High filtration efficiency
Fibrous structure is dense, with surface coating options available, offering filtration accuracy exceeding 99.99%, suitable for stringent emissions requirements.
High mechanical strength, good dimensional stability
Maintains structural integrity in high-speed airflow and dust erosion environments, resists deformation or damage.
5. Easy-to-clean, long-lasting
Smooth surface, excellent dust shedding properties, when used with the pulse cleaning system, can extend service life to over 3 years.
6. Optional composite form
PPS+PTFE composite filter bags further enhance oxidation resistance, water resistance, condensation prevention, etc., 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.
