Material Characteristics
High Porosity: The porosity of polyester needle-punched filter materials can exceed 70%, double that of woven filter fabrics, enhancing filtration efficiency and reducing pressure drop.
Excellent Air Permeability: High porosity contributes to superior air permeability, which helps reduce equipment operating resistance and conserve energy.
Strong Abrasion Resistance: Polyester fibers inherently possess good abrasion resistance, enabling the filter material to maintain good performance over extended periods of use.
Acid and Alkali Resistance: Polyester needle-punched filter materials can withstand a certain degree of acid and alkali corrosion, making them suitable for various working environments.
High Temperature Resistance: Typically stable for prolonged use at around 120°C, with some products exhibiting even higher heat resistance.
Application Areas
- Metallurgy: Used for dust removal and gas purification during smelting processes.
- Chemical Industry: Filters corrosive gases and liquids in chemical production.
- Light Industry: Process filtration in industries such as textiles and papermaking.
- Pharmaceuticals: Air purification during drug manufacturing.
- Environmental Protection: Fields like wastewater treatment, smoke and dust removal, and air filtration and purification.
