无机玻璃钢风管按其胶凝材料性能分为：以硫酸盐类为胶凝材料与玻璃纤维网格布制成的水硬性无机玻璃钢风管和以改性氯氧镁水泥为胶凝材料与玻璃纤维网格布制成的气硬性改性氯氧镁水泥风管两种类型。胶凝材料硬化体的PH值应小于8.8,并不应对玻璃纤维有碱性腐蚀。无机玻璃钢风管分为整体普通型（非保温）、整体保温型（内、外表面为无机玻璃钢，中间为绝热材料）、组合型（由复合板、专用胶、法兰、加固角件等连接成风管）和组合保温型四类，其制作参数应符合表 1、 2、 3的规定。
According to the performance of the cementitious material, the air duct of the inorganic glass fiber reinforced plastics can be divided into two types: the hydraulic inorganic glass fiber reinforced plastics air duct which is made of the sulfate as the cementitious material and the glass fiber gridding cloth, and the pneumatic modified magnesium oxychloride cement air duct which is made of the modified magnesium oxychloride cement and the glass fiber gridding cloth. The pH value of cementitious material hardening body shall be less than 8.8, and it shall not have alkaline corrosion on glass fiber. The inorganic FRP air duct is divided into four types: the overall ordinary type (non thermal insulation), the overall thermal insulation type (the internal and external surfaces are inorganic FRP, and the middle is thermal insulation material), the combined type (the air duct is connected by composite plate, special glue, flange, reinforced angle pieces, etc.) and the combined thermal insulation type. The manufacturing parameters shall meet the requirements of tables 1, 2 and 3.
