无机玻璃钢
Inorganic FRP
无机玻璃钢通风管(又称玻璃纤维氯氧镁水泥通风管)是以氯氧镁水泥为胶结料中碱玻璃纤维为增强材料、加入填充材料和改性剂等所制成的一种管材。它具有不燃烧、属不燃材料A级，耐腐蚀、强度高和重量轻等特点。在建筑工程、地下工程及工业厂房的通风中，它已经完全取代了不耐燃的有机玻璃钢通风管，并在逐步取代防腐性能差的镀锌铁皮通风管。尤其是在湿度大的地下工程和长江以南地区，它的优越性更为显著。
Inorganic glass fiber reinforced plastic ventilation pipe (also known as glass fiber magnesium oxychloride cement ventilation pipe) is a kind of pipe made of alkali glass fiber reinforced with magnesium oxychloride cement as binder, filling material and modifier. It has the characteristics of non-combustible, www.baodingbaojie.cn www.mojuzhizuo.com www.gelidunmoju.com.cn www.jiezhuangmoju.cn www.suolijc.com www.china-for.comnon-combustible material A, corrosion resistance, high strength and light weight. In the ventilation of construction, underground engineering and industrial workshop, it has completely replaced the non-flammable organic glass fiber reinforced plastic ventilation pipe, and gradually replaced the galvanized iron sheet ventilation pipe with poor anticorrosive performance. Especially in underground projects with high humidity and areas south of the Yangtze River, its advantages are more obvious.
通过氯氧镁胶凝材料的研究及制品的检测，发现无机玻璃钢通风管在生产中及工程应用中仍存在一些质量问题。有的质量问题严重影响了工程的使用寿命，应引起大家足够重视。
Through the research of magnesium oxychloride cementitious material and the inspection of products, it is found that there are still some quality problems in the production and engineering application of inorganic FRP ventilation pipe. Some quality problems seriously affect the service life of the project, which should be paid enough attention to.

classification
根据国家建筑材料行业标准《玻镁风管》JC646-2006标准的规定，通风管道分为整体普通型风管、整体保温型风管和组合保温型风管三种类型，该三种通风管道不适用于住宅建筑的排油烟管道。
According to the national building materials industry standard JC646-2006, ventilation ducts are divided into three types: integral common duct, Integral Insulation duct and combined insulation duct. These three types of ventilation ducts are not suitable for exhaust fume pipelines in residential buildings.
根据通风管道的物理力学性能和外观质量，通风管道分为一级品和合格品两个等级。
According to the physical and mechanical properties and appearance quality of the ventilation duct, the ventilation duct can be divided into two grades: the first grade and the qualified grade.
