無機玻璃鋼(gang)通風管
無機玻(bo)璃(li)(li)鋼通(tong)(tong)(tong)風(feng)(feng)管(guan)(guan)（又(you)稱玻(bo)璃(li)(li)纖維氯氧鎂水泥通(tong)(tong)(tong)風(feng)(feng)管(guan)(guan)）是以氯氧鎂水泥為(wei)膠結料中(zhong)堿玻(bo)璃(li)(li)纖維為(wei)增強(qiang)材(cai)料、加(jia)入填充(chong)材(cai)料和改性劑(ji)等所制成的(de)(de)一(yi)種管(guan)(guan)材(cai)。它具有(you)不燃(ran)燒、屬不燃(ran)材(cai)料A級，耐腐蝕、強(qiang)度高和重量輕等特點(dian)。在建筑(zhu)工(gong)(gong)程、地(di)(di)下(xia)工(gong)(gong)程及工(gong)(gong)業廠房的(de)(de)通(tong)(tong)(tong)風(feng)(feng)中(zhong)，它已(yi)經(jing)完全(quan)取代(dai)了不耐燃(ran)的(de)(de)有(you)機玻(bo)璃(li)(li)鋼通(tong)(tong)(tong)風(feng)(feng)管(guan)(guan)，并(bing)在逐步(bu)取代(dai)防腐性能差的(de)(de)鍍(du)鋅鐵皮通(tong)(tong)(tong)風(feng)(feng)管(guan)(guan)。尤其是在濕度大(da)的(de)(de)地(di)(di)下(xia)工(gong)(gong)程和長江以南地(di)(di)區(qu)，它的(de)(de)優越性更為(wei)顯著。
; 通過氯氧鎂膠(jiao)凝材料的(de)研究及(ji)制(zhi)品的(de)檢測，發(fa)現無(wu)機玻璃鋼(gang)通風管在生產中(zhong)及(ji)工程應用(yong)(yong)中(zhong)仍存(cun)在一些質量(liang)問題。有的(de)質量(liang)問題嚴重影響了工程的(de)使用(yong)(yong)壽命，應引起大家足夠重視(shi)。
