What is glass fiber knitted felt? What’s the difference between glass fiber needle felt and chopped felt? Glass fiber needle felt is a kind of filter material with superior performance: high porosity, low gas filtration resistance, high filtration wind speed, high dust removal efficiency, bending resistance, wear resistance, stable size and so on.
Main uses
Glass fiber needled felt can be used for sound insulation, sound absorption, shock absorption and flame retardation in the automotive industry, mainly in the field of industrial filtration; Glass fiber needle felt is widely used in flue gas purification and dust recovery of carbon black, steel, non-ferrous metals, chemical industry, incineration and other industries.
Working condition
1. The filtering wind speed should be less than 1.0 m / min
2. The working temperature of glass fiber needled felt should be less than 260 ℃
Medium and alkali free glass fiber bulky filter cloth / bag
Medium and alkali free glass fiber bulky filter materials are produced by applying the technology of Nanjing glass fiber Institute and adopting German imported expansion equipment. The weave has double satin and twill.
The specifications of medium and non alkali glass fiber bulky filter cloth (bag) are as follows: Φ 120-300 mm, with the performance of ordinary glass fiber filter material. At the same time, after high temperature hot washing, the fabric structure is enhanced, the wear resistance is increased, the filtering wind speed is increased, and the service life is greatly improved.
Main uses
Medium and alkali free expanded glass fiber filter cloth (bag) is widely used in dust removal and gas filtration in iron and steel, electric power, metallurgy, chemical industry, environmental protection, cement and other industries.
Working condition
Long term use 200 ℃ – 280 ℃, the best use temperature 90 ℃ – 220 ℃, FCA formula working temperature should be less than 180 ℃; The filtering wind speed should be less than 0.8m/min.
