无机玻璃钢通风管道的耐热性能好

能在300℃温度条件下使用。其防火性能更佳，经国家防火建材质量检测中心检验，无机玻璃钢通风管道属A级不然材料。因此，无机玻璃钢通风管道的耐热性和防火性能均优于聚酯玻璃钢管。无机玻璃钢通风管道可以手糊成型，也可机械化生产出板材后再裁切粘接成型。生产过程无有害气体排出，不污染环境，不影响盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门工人健康，无机玻璃钢通风管道分为保温夹层泥杆 保定空压机 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修 托辊设备  托辊生产线结构管和不保温单层结构管两种。夹层保温管可一次在工厂造好，现场只需定位安装就可，不像镀锌铁皮风管那样，风管安装后，还要再在铁皮外包覆保温层，增加现场施工难度，延长工期。无机玻璃钢通风管道还可以在施工现场先拼接2～3节管，使其成一整体较长管，一次吊装，省时省工。

Inorganic FRP ventilation duct has good heat resistance and can be used at 300 ℃. Its fireproof performance is better. According to the inspection of the national fireproof building materials quality inspection center, the inorganic FRP ventilation pipe is a class a material. Therefore, the heat resistance and fire resistance of inorganic FRP ventilation pipe are better than polyester FRP pipe. Inorganic FRP ventilation duct can be hand pasted and formed, or it can be cut and bonded after mechanized production of plates. The production process has no harmful gas discharge, does not pollute the environment, and does not affect the covering net, cold proof cloth, hemp rope, oil hemp rope, hemp knife, asphalt hemp rope static pressure molding line, automatic pouring machine, cast iron clapping door, steel clapping door, FRP clapping door, workers' health, and inorganic FRP ventilation pipes are divided into thermal insulation sandwich structure pipe and non thermal insulation single-layer structure pipe. The sandwich insulation pipe can be made in the factory at one time, and only needs to be installed in position on site. Unlike the galvanized iron sheet air duct, after the installation of the air duct, the iron sheet should be covered with insulation layer to increase the difficulty of on-site construction and prolong the construction period. The inorganic FRP ventilation pipe can also be spliced with 2 ~ 3 pipes at the construction site to form a whole long pipe, which can be hoisted at one time, saving time and labor.
