PPS bags are high-performance dust removal bags made primarily from Polyphenylene Sulfide (PPS) fibers, produced through processes such as three-dimensional needle-punching. They feature the following outstanding characteristics:
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 chemical resistance
Exhibits excellent stability against corrosive gases like sulfur oxides (SO?, SO?), acids, and bases; commonly used in power plant desulfurization, chemical industry, metallurgy, and other sectors.
3. High filtration efficiency
The fiber structure is dense, with the surface available 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 abrasion environments, resists deformation or damage.
5. Easy-to-clean, long lifespan
Surface smooth, excellent dust shedding 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 anti-dew performance, 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 applications, widely used in industries such as power, steel, cement, and waste incineration.
