Fumeisi FMS filter bags are high-performance composite filtration materials developed by blending fluorine-containing fibers (e.g., PTFE) with high-temperature resistant fibers (e.g., fiberglass, aramid). They combine the advantages of multiple materials, offering superior temperature resistance, chemical stability, and mechanical strength for harsh industrial applications.
Key Features
- Enhanced Temperature Resistance: Continuous operation at?200–260°C, with short-term exposure up to 280°C.
- Exceptional Chemical Resistance: Resists strong acids, alkalis, and organic solvents (including HF corrosion when specially treated).
- Optimized Structure: Multi-layer composite design ensures high filtration efficiency (>99.9%) and low pressure drop.
- Extended Service Life: 2–3 times longer than conventional fiberglass bags under the same conditions.
- Adaptable Surface Treatments: Optional PTFE coating, singeing, or calendering for specific applications.
Applications of FMS filter bag
- Cement Plants: Kiln head/kiln tail dedusting, clinker cooler applications.
- Waste Incineration: Flue gas treatment with high moisture and acid content.
- Non-Ferrous Metallurgy: Copper/lead/zinc smelting off-gas filtration.
- Chemical Industry: Sulfuric acid production, titanium dioxide processing.
- Power Generation: CFB boilers with high sulfur coal combustion.
