Product Description
Glass fiber needle felt is a kind of filter material with high performance: high porosity, low gas filtration resistance, large filtration wind speed, high dust removal efficiency, and has the characteristics of bending resistance, wear resistance, and stable size.
The main purpose
Fiberglass needle felt can be used for sound insulation, sound absorption, shock absorption, flame retardancy, etc. in the automotive industry, mainly used in the field of filtration in the industry; glass fiber needle felt is widely used in carbon black, steel, nonferrous metals, chemical industry, incineration Flue gas purification and dust recycling in other industries.
Operating conditions
1. The filtering air speed should be less than 1.0m / min.
2. The working temperature of glass fiber needle felt should be less than 260 ℃
Medium and non-alkali glass fiber expanded filter cloth / bag
Medium and non-alkali glass fiber expanded filter material is the application of Nanjing Glass Fiber Institute technology, using German imported expansion equipment to produce fully expanded or two-thirds expanded filter cloth (bag). The organization includes weft double satin and twill.
The product specifications of medium and non-alkali glass fiber expanded filter cloth (bag) are Φ120-300mm, which has 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, and the filtration wind speed is increased , The service life is greatly improved.
The main purpose
Medium and non-alkali expanded glass fiber filter cloths (bags) are widely used in dust-removing filter gas in industries such as steel, power, metallurgy, chemical industry, environmental protection, cement and other industries.
Working condition
Long-term use of 200 ℃ -280 ℃, _use temperature of 90 ℃ -220 ℃, FCA formula working temperature should be less than 180 ℃; filtration air speed should be less than 0.8m / min.
