玻镁复合风管全部采用胶接结构制作而成，无法兰连接，大大提高了风管的密闭性，与铁皮风管相比，减少了咬口和法兰的漏风，降低了风管的 漏风率，提高了空气输送的效率，玻镁复合风管的漏风率仅为铁皮风管的 1/10 。 玻镁复合风管采用机械化生产，表面光滑、平滑， 摩擦系数小，风阻低，风管表面 绝对粗糙度 0.2mm 。 玻镁复合风管具有良好的隔音性能，同时保温材料具有减振和 吸音性能，所以能够降低空气颤动和机械产生的噪声及消除铁皮风管收缩和扩张产生的噪声，保持室内环境安静。玻镁复合风管性能优于铁皮风管，综合造价低于铁皮风管，为客户节省一次性投资。
The glass magnesium composite air duct is made of adhesive structure without flange connection, which greatly improves the airtightness of the air duct. Compared with the iron sheet air duct, it reduces the air leakage of the bite and flange, reduces the air leakage rate of the air duct, and improves the efficiency of air transmission. The air leakage rate of the glass magnesium composite air duct is only 1 / 10 of that of the iron sheet air duct. The glass magnesium composite air duct is manufactured by mechanization, with smooth surface, small friction coefficient, low wind resistance and 0.2mm absolute surface roughness. The glass magnesium composite air duct has good sound insulation performance, and the insulation material has vibration damping and sound absorption performance, so it can reduce the noise caused by air vibration and machinery, eliminate the noise caused by the contraction and expansion of the iron sheet air duct, and keep the indoor environment quiet. The performance of glass magnesium composite air duct is better than that of iron sheet air duct, and the comprehensive cost is lower than that of iron sheet air duct, so as to save one-time investment for customers.
