PPS bag filters are high-performance dust removal bags made primarily from polyphenylene sulfide (PPS) fibers. Due to their excellent resistance to high temperatures, corrosion, high filtration accuracy, and good cleaning performance, they are widely used in various industrial fields. In environments with high-temperature flue gas emissions, such as coal-fired power plants, waste incineration plants, steel mills, and cement factories, PPS bag filters can effectively capture dust particles, meet strict environmental emission standards, and are particularly suitable for complex operating conditions containing acidic gases (such as SO?, SO?) and alkaline dust. In addition, PPS bag filters can also be used in flue gas purification systems for industries like chemicals, metallurgy, and coking, ensuring equipment stability and extending service life. They are one of the key materials for achieving industrial dust emission standards.Chlorine and ammonia-containing flue gases emitted from chemical reaction kettles are highly corrosive to filter materials. After being impregnated with PTFE emulsion, the PPS fabric bags form a dense protective film on the fiber surface. After alternating aging with *** for 48 hours, the strength retention rate remains above 85%; its flame-retardant index reaches UL94 V0 level, with an oxygen index of 34%, and does not ignite even when exposed to high-concentration organic solvent sparks. The surface resistance of the coated film is reduced to 10?Ω, effectively preventing static accumulation and ensuring the safe operation of flammable dust conditions; it can operate continuously for two years without replacement, providing the enterprise with a safe, stable, and low-cost flue gas treatment solution.In industrial production processes, dust control is a critical component. PPS bags maintain stable performance under high temperature and humidity conditions due to their material characteristics, thereby extending their service life. Compared to other materials, PPS bags excel in acid and alkali resistance, making them suitable for handling flue gases containing corrosive gases. This makes them the preferred filter material for many industrial dust removal systems.
