Glass Fiber Needle Punched Filter Material
What Is Glass Fiber Needle Punched Filter Material?
A: Glass fiber needle punched filter material is a high-performance filtration material made of glass fibers via needle punching. It features exceptional high-temperature resistance, corrosion resistance, and mechanical strength, available in variants (HNWn600, HNWn900, HNWn1050) to suit different filtration load and strength requirements in high-temperature flue gas industries.
Performance and Characteristics
Core Advantages
HNWn600 Glass Fiber Needle Filter Material
Specifications: Unit weight 600±50 g/m², fiber diameter 5.5μm (filter layer and base fabric).
Advantages: Good wear resistance, moderate tensile strength, high dust removal efficiency, and filtration wind speed up to 1.0–1.3 m/min. It possesses glass fiber properties like high temperature resistance (280℃ continuous, 350℃ instant), corrosion resistance, and low elongation, suitable for low filtration load high-temperature flue gas industries (steel, cement, power, chemical).
HNWn900 Glass Fiber Needle Filter Material
Specifications: Unit weight 900±50 g/m², fiber diameter 5.5μm (filter layer and base fabric).
Advantages: Excellent wear resistance, good tensile strength, high dust removal efficiency, and filtration wind speed up to 1.0–1.3 m/min. Retains glass fiber's high temperature, corrosion resistance, and low elongation, making it an ideal flue gas dust removal material for steel, cement, power, and chemical industries.
Function & Application
It is widely used in high-temperature flue gas dust removal for industries like steel, cement, power, and chemical. It effectively removes dust from high-temperature flue gas, ensuring compliance with emission standards and protecting equipment in harsh thermal and corrosive environments.
