　　Fiberglass ventilation pipe is made of inorganic binder and fiberglass cloth by modeling, batching, pasting, foam discharging, curing and aging. It has the advantages of light weight, high strength, water resistance, aging resistance, non burning in case of fire, smoke-free, tasteless, non-toxic and corrosion resistance. It fundamentally deals with the disadvantages of easy burning of organic glass fiber reinforced plastics, easy corrosion of iron sheet air duct and short service life.

　　廣泛應(yīng)用于賓館、商場(chǎng)、紡織、化纖、石油化工、機(jī)械制造、外表、電子、醫(yī)藥、煙草、食物、醫(yī)療、倉(cāng)儲(chǔ)、寫(xiě)字樓以及地鐵、人防、地下室等工程的送風(fēng)、排風(fēng)、排煙管道，非常修建中需求防火的通風(fēng)管道。

　　產(chǎn)品特色 不燃型無(wú)機(jī)玻璃鋼風(fēng)管產(chǎn)品特色：質(zhì)量輕、強(qiáng)度高、不燃、抗老化、耐腐蝕、阻力小、密封性能好、外形漂亮、裝置簡(jiǎn)略、運(yùn)用壽命長(zhǎng)；運(yùn)用的原資料均為無(wú)機(jī)資料，遇火不焚燒，防火性能優(yōu)越；耐酸、堿、鹽等腐蝕，能習(xí)慣不同區(qū)域氣候條件。

　　Product features non flammable inorganic glass fiber reinforced plastic duct features: light weight, high strength, non combustible, anti-aging, corrosion resistance, small resistance, good sealing performance, beautiful appearance, simple device, long service life, raw materials used are inorganic materials, fire does not incinerate, fire performance is superior, acid, alkali, salt and other corrosion, can be used to different regional climate conditions.

　　非常是空氣中含鹽份較高的沿海區(qū)域和化工、醫(yī)藥、煙草、化纖等含有或帶有揮發(fā)性介質(zhì)的職業(yè)，更能表現(xiàn)其耐腐蝕的優(yōu)越性；產(chǎn)品無(wú)毒、無(wú)味、無(wú)石棉、無(wú)揮發(fā)性介質(zhì)、無(wú)粉塵發(fā)生，經(jīng)衛(wèi)生部門(mén)查驗(yàn)，對(duì)人體無(wú)害，契合gb/5465-1985《修建資料不燃性實(shí)驗(yàn)辦法》規(guī)范。

　　In particular, the coastal areas with high salt content in the air and the occupations with or containing volatile media, such as chemical industry, medicine, tobacco, chemical fiber, etc., are more able to show their advantages of corrosion resistance; the products are non-toxic, tasteless, asbestos free, volatile media free, dust free, which are harmless to human body after inspection by the Ministry of health, and conform to the standard of GB / 5465-1985 "experimental method for the non flammability of construction data" 。
