PPS bags are made primarily from Polyphenylene Sulfide (PPS) fibers and produced through processes like three-dimensional needle punching, 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 and high-temperature flue gas environments in coal-fired boilers, waste incineration, etc.
2. Strong resistance to chemical corrosion
Demonstrates excellent stability against corrosive gases such as sulfur oxides (SOx, SOy), acids, and alkalis, commonly used in power plant desulfurization, chemical industry, metallurgy, and other sectors.
High filtration efficiency
The fiber structure is dense, with a surface suitable for coating 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, resistant to 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 enhancing oxidation resistance, water resistance, condensation prevention, etc., suitable for more complex operating conditions.
In summary,PPS bags are an ideal dust collection material for high-temperature, high-corrosion, and high-filtration precision conditions, widely used in industries such as power, steel, cement, and waste incineration.
