First, high-temperature glass fiber needle felt dust bag Profile fiberglass high temperature needle felt bag (dust bag) is a superior performance of the filter material, porosity, gas filtration resistance, filtration velocity, high collection efficiency while resistant to bending, wear and dimensional stability characteristics. High temperature resistant glass fiber needle felt bag filtration velocity should be less than 1.0m / min, the glass fiber needle felt temperature should be less than 260 ℃, the E-glass fiber filter cloth expanded / bag, E-glass fiber filter cloth expanded / bag puffed equipment imported from Germany, two-thirds of the entire production expansion or expanded filter cloth (bag). Organization weft double satin, twill. Bulked E-glass fiber filter cloth (bags) Product specifications are Φ120-300mm, with general performance glass fiber filter material, while the high-temperature heat washing the fabric tissue enhancement, increased wear resistance, filtration velocity increases, the use of life greatly improve long-term use of 200 ℃ -280 ℃, the optimum temperature 90 ℃ -220 ℃, FCA recipe temperature should be less than 180 ℃;. filtration velocity should be less than 0.8m / min. P84 characteristics due to the fineness of the fiber itself significantly, but also because of the irregular fiber cross section of the fiber surface area increases to a maximum and provide a lot of tiny pores to the surface of the filter is better than the depth of the filter. Dust stop at the surface of the filter mat It failed to penetrate the filter mat, therefore backwashing pressure small mud cake removal efficiency can be significantly improved, with excellent micro-powder collection efficiency and the operating pressure. Suitable for coal-fired boilers, fluid bed boilers, waste incineration, asphalt plants, cement plants, waste incinerators, etc. Second, high-temperature glass fiber needle felt needle felt dust bag use fiberglass insulation can be used in the automotive industry, sound absorption, shock absorption, flame retardant, mainly used in the field of filtration industry, glass fiber needle felt widely carbon black, iron and steel, nonferrous metals, chemicals, and other industries incineration flue gas purification and dust recycling. High temperature glass fiber needle felt can be widely used in chemical, steel, metallurgy, carbon black, power generation, cement kilns and other industrial high-temperature flue gas filter for cleaning and pulse cleaning dust and other higher speed baghouse. Third, high temperature resistant glass fiber needle felt dust bag Specifications Model: φ133 * 2000mm φ133 * 6050mm φ160 * 6050mm φ165 * 6050mm φ133 * 2450mm φ120 * 2000mm φ250 * 3000mm φ250 * 4000mm φ250 * 5000mm φ250 * 6000mm and so on. Can be customized according to customer requirements of different size lengths.
