 Composite fiberglass duct composite fiberglass duct cutting tool through the composite glass wool board, bonding, sealing tape sealing and reinforcement from. Composite glass wool board double protective layer of aluminum foil or glass fiber cloth to the inner protective layer of glass fiber cloth, the middle laminated glass wool board, glass wool by centrifugation of fiber glass is formed by the hot plastic resin, curing. Common specifications sheet: Density 70-75kg/m3, thickness 25mm. Due to the porous composite glass wool sandwich panels of lightweight materials, low thermal conductivity, sound absorption coefficient, thus duct insulation and has a good performance muffler; Moreover, duct has a light weight, short construction period, as fire, moisture, no harmful volatile compounds, appearance, long life, and low cost. Composite fiberglass duct Features 1. Material reliable, beautiful appearance duct material selection entirely by normative standards and testing, no substitutes, wind pipe production strictly according to process requirements and quality control processes under the material and into tubes, accurate size, combined with tight. Appearance, can effectively prevent water condensation occurs. 2 good insulation properties of composite fiberglass duct wall of glass wool sandwich panels with a certain thickness, is a good insulating material, the determination of the density of 70-75kg/m3, the thermal conductivity equation for composite glass wool board : λ = 0.029 +0.000125 tpw / m · ℃ where tp is the average temperature of the duct wall (℃).. Commonly used on the project with a density of 48 kg/m3 or less glass wool insulation materials, the thermal conductivity of small 6-9%; compared with rock wool board insulation materials, thermal coefficient of 18-25%; room temperature thermal conductivity of 0.025 w / m · K, superior general insulation materials, while the outer layer of composite fiberglass duct wall is smooth aluminum foil, heat-reflective rate of 95% over the outer surface of the radiant heat is close to zero, the heat transfer coefficient can be reduced by 20-28 %. Therefore composite fiberglass duct for ventilation and air conditioning systems with the best insulation properties, saving air conditioning energy consumption, with the plate and pipe insulation systems compare, for an investment project to save more than 30% of the project costs and operating costs.
