Definition
Glass fiber needle felt is a kind of glass fiber as raw material, which is used for needle punching of carded short-cut glass fiber felt, mechanically made between felt glass fiber, felt glass fiber and reinforced glass fiber base cloth. A felt-like nonwoven fabric filter material in which fibers are intertwined and a web is reinforced.
Characteristics
The glass fiber monofilament is randomly interlaced and interlaced, and has an unoriented three-dimensional microporous structure with small voids and large porosity, and has good sound absorption, shock absorption, corrosion resistance, insulation, high temperature resistance and flame retardant performance. High porosity, low gas filtration resistance, high filtration wind speed, high dust removal efficiency, bending resistance, wear resistance and dimensional stability are high-speed and high-efficiency high-temperature filter materials.
Use
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 field in the industry; high temperature flue gas filtration; glass fiber needle felt is widely used in carbon black, steel, colored Various bag filters for flue gas purification and dust recovery in industries such as metals, chemicals, and incineration.
