Description

Cement kiln tail gas temperatures at 160℃, high alkali content, and strong dust erosion. PPS filter bags form a "fine-tight-firm" three-layer barrier through gradient needle-punching structure, with the surface fine fibers intercepting PM2.5 and the bottom coarse fibers resisting high-speed impact. After coating, the pore size is controlled at 0.2μm, achieving a 99.99% filtration efficiency for alkaline particles. After 28 days of alkali resistance testing, the quality loss rate is less than 0.1%, significantly superior to conventional aramid filter materials. The pulse cleaning frequency is extended from once every 60 minutes to 90 minutes, reducing compressed air consumption by 15%, potentially saving tens of thousands of yuan in electricity and maintenance costs for the entire year.

The exhaust gases from chemical reaction kettles containing chlorine and ammonia are highly corrosive to filter materials. After being impregnated with PTFE emulsion, the fiber surface forms a dense protective film. After 48 hours of alternating aging with ***, the strength retention rate remains above 85%; its flame-retardant index reaches UL94 V0 level, with a limiting oxygen index of 34%, and it does not ignite even when exposed to high-concentration organic solvent flashes; the surface resistance of the coated film is reduced to 10?Ω, effectively preventing static accumulation and ensuring safe operation in flammable dust conditions; it can operate continuously for two years without replacement, providing the enterprise with a safe, stable, and low-cost exhaust gas treatment solution.

PPS (polysulfone) is a high-performance fiber with excellent heat resistance and chemical stability. The coated PPS filter bags are further enhanced with a microporous film on the surface of the PPS fibers, improving filtration accuracy and dust removal efficiency. These bags maintain stability in high-temperature, high-humidity, or corrosive gas environments, offering a longer service life.
