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

The inorganic glass fiber reinforced plastic air pipe is divided into three parts: the cementitious material and the fiberglass reinforced plastic, and the modified magnesium oxychloride cement and glass fiber.

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

There are two types of pneumatic modified magnesium oxychloride cement wind pipe made of grid cloth. The pH value of the hardened body of a cementitious material

应小于8.8,并不应对玻璃纤维有碱性腐蚀。

It should be less than 8.8, and it should not have alkaline corrosion to glass fiber.

      

      

无机玻璃钢风管应采用无碱、中碱或抗碱玻璃纤维网格布，并分别符合现

Inorganic glass steel wind pipe should be used for alkali free, middle alkali or alkali resistant glass fiber mesh.

行国家标准《玻璃纤维网格布》JC561、《无碱玻璃纤维、无捻粗纱布》JC/T281、《中碱玻璃纤维无捻粗纱布》JC/T576的规定。氯氧镁水泥风管氧化镁的品质应符合现行国家标准《菱镁制品用轻烧氧化镁》WB/T1019-2002的规定。

It is stipulated in the national standard "glass fiber mesh cloth" JC561, "alkali free glass fiber, no twist coarse gauze" JC/T281, "medium alkali glass fiber coarse twist gauze" JC/T576. The quality of magnesium oxychloride cement duct Magnesium Oxide should comply with the national standard "Magnesium Oxide" light burned magnesite products with WB/T1019-2002 regulations.

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。

Inorganic glass steel duct into the overall common type (non insulation), integral insulation type (inner and outer surface of inorganic glass steel, middle insulating material) and combination type (wind pipe by composite plate, special glue, flange reinforced connection angle etc) and composite insulation type four kinds, the manufacturing the parameters should comply with the provisions of the table 1, 2, 3.

玻璃纤维网格布相邻层之间的纵、横搭接缝距离应大于300mm，同层搭接缝距离不得小于500mm。搭接长度应大于50mm。

The distance between the longitudinal and transverse joints between the adjacent layers of the glass fiber mesh fabric should be greater than 300mm, and the distance between the joints of the same layer should not be less than 500mm. The lap length should be greater than 50mm.

风管表层浆料厚度以压平玻璃纤维网格布为宜(可见布纹)。且表面不得有密集气孔和漏浆。

The wind pipe surface thickness of the slurry with flat glass fiber mesh cloth is appropriate (see:). There are no dense pores and leakage of slurry on the surface.
