It is widely used in sandwich insulation and noise elimination systems in electromechanical, chemical, construction, transportation, automobile and other industries, as well as as as thermal insulation and fireproof materials. The filtering wind speed should be less than 65438±0.0m/min, and the working temperature of glass fiber needled felt should be less than 260℃. Used for thermal insulation of high-temperature equipment and central air-conditioning pipes with various heat sources (coal, electricity, oil and gas). Used for all kinds of heat insulation and fireproof materials. Sealing, sound absorption, filtering and insulating materials for special places. Used for heat preservation of various heat transfer and heat storage devices. Used for sound insulation, heat insulation and heat resistance of vehicles, ships, airplanes and other parts. Sound insulation of muffler inner core of automobile and motorcycle and noise elimination of engine. Colored steel plate and wood structure houses are insulated by layers of insulation. The thermal insulation effect of chemical pipeline is better than that of general thermal insulation materials. Insulation of household appliances such as air conditioners, refrigerators, microwave ovens and dishwashers. Other occasions requiring heat preservation, heat insulation, fire prevention, sound absorption and heat insulation.

The alkali-free glass fiber expanded filter material is a fully expanded or two-thirds expanded filter cloth (bag) produced by the technology of Nanjing Glass Fiber Research Institute and the expansion equipment imported from Germany. The weave is double satin and twill. The product specification of neutral alkali-free glass fiber expanded filter cloth (bag) is φ 120-300mm, which has the performance of ordinary glass fiber filter material. At the same time, after high-temperature hot washing, the fabric structure is strengthened, the wear resistance is increased, the filtration wind speed is increased, and the service life is greatly improved. Main uses: alkali-free expanded glass fiber filter cloth (bag) is widely used for dust removal and gas filtration in steel, electric power, metallurgy, chemical industry, environmental protection, cement and other industries. Long-term use of 200℃-280℃, the best use temperature of 90℃-220℃, the working temperature of FCA formula should be less than180℃; The filtering wind speed should be less than 0.8m/min.
