High-Temperature Dust Collector Filter Bag – Heat & Corrosion-Resistant, Efficiently Meeting High-Temperature Challenges

High-temperature dust collector filter bags are manufactured from high-temperature resistant chemical fibers (such as PPS, PI, PTFE) through a needle-punching process. They exhibit exceptional high-temperature resistance, corrosion resistance, and mechanical strength, making them suitable for flue gas dust collection applications at temperatures exceeding 200 ° C. They are widely used in flue gas dust collection systems across thermal power plants, cement plants, steel plants, waste incineration facilities, and other industrial applications.

Post-Treatment Process
Singeing

Burning off surface fuzz of the filter bag with a flame to create a smooth surface and reduce dust adhesion.

Calendering

Rolling the filter media under high temperature and pressure to flatten the surface, densify the structure, and enhance dimensional stability.

Membrane Lamination

Thermally laminate an ePTFE membrane onto the surface of the filter media, creating a microporous filtration layer that enhances filtration precision.

Heat Setting

Heating the filter bag at a specific temperature to stabilize the fiber molecular structure, thereby extending its service life and improving dimensional stability.

Water-and Oil-Repellent Treatment

Impregnating the filter media with fluorocarbon resin or PTFE emulsion to form a water- and oil-repellent coating, ideal for humid or oil-laden gas environments.

Anti-static Treatment

Blending conductive fibers into the filter media, designed for flammable or explosive dust environments to prevent static buildup and the risk of explosion.
