The glass fiber needle felt not only has the advantages of high temperature resistance, corrosion resistance, dimensional stability, minimal elongation and shrinkage, and high strength of the glass fiber fabric, but also the felt fiber is single fiber, three-dimensional microporous structure, high porosity, and gas Small filtration resistance is a high-speed and high-efficiency high-temperature filter material.
The characteristic of glass fiber needle felt is that the glass fiber monofilament is disorderly interspersed and interspersed, showing a non-directional three-dimensional micro-hole structure, with small gaps, large gaps, good sound absorption, shock absorption, corrosion resistance, insulation, high temperature resistance, flame retardancy Performance. High porosity, low gas filtration resistance, large filtration wind speed, high dust removal efficiency, and resistance to bending, abrasion and dimensional stability. . Compared with other high temperature resistant fiber mats, it has special advantages such as low price and higher temperature resistance, but its running resistance is higher than that of general chemical fiber high temperature filter materials.
Glass fiber needle felt can be used in the automotive industry for sound insulation, sound absorption, shock absorption, flame retardant, etc., mainly used in the filtration industry; high temperature flue gas filtration; glass fiber needle felt widely used in carbon black, steel, colored Metal, chemical, incineration and other industries flue gas purification and dust recycling bag filter.
