Water-Repellent, Oil-Resistant, and Anti-Static Polyester Needle-Punched Dust Filter Bags

2.1.3 Water-Repellent, Oil-Resistant, and Anti-Static Polyester Needle-Punched Dust Filter Bags
The water-repellent, oil-resistant, and anti-static polyester needle-punched filter bag (Triple-Protection) uses polyester needle-punched felt as the base material. Its surface is treated with PTFE membrane coating or fluorine-containing impregnation to form hydrophobic/oleophobic layers, and incorporates conductive fibers (surface resistance ≤10⁸ Ω).
①Performance Parameters:Temperature resistance: ≤130℃;Air permeability: 3–15 m³/m²·min (varies by process).
②Applications:Grain processing, coal powder collection, and other medium-low temperature (≤130℃) scenarios with oil mist, high humidity, or flammable dust (in EX environments);Weak solvent-containing scenarios (e.g., coking plants), where temperature must be controlled <100℃, prioritizing conductive fiber blended processes to ensure explosion-proof safety.
