無機玻璃鋼(gang)通風管
無機玻(bo)(bo)璃(li)鋼通(tong)(tong)風(feng)管(guan)(guan)（又稱玻(bo)(bo)璃(li)纖(xian)維氯氧鎂水泥(ni)(ni)通(tong)(tong)風(feng)管(guan)(guan)）是(shi)以氯氧鎂水泥(ni)(ni)為(wei)膠結料中(zhong)堿玻(bo)(bo)璃(li)纖(xian)維為(wei)增強(qiang)(qiang)材(cai)(cai)(cai)料、加入填(tian)充材(cai)(cai)(cai)料和改(gai)性(xing)(xing)劑等所制成(cheng)的一種管(guan)(guan)材(cai)(cai)(cai)。它(ta)(ta)具有不(bu)燃(ran)燒、屬不(bu)燃(ran)材(cai)(cai)(cai)料A級，耐腐(fu)(fu)蝕(shi)、強(qiang)(qiang)度高和重(zhong)量輕等特點。在建筑工(gong)程(cheng)、地(di)下工(gong)程(cheng)及(ji)工(gong)業廠(chang)房的通(tong)(tong)風(feng)中(zhong)，它(ta)(ta)已經完全取代了不(bu)耐燃(ran)的有機玻(bo)(bo)璃(li)鋼通(tong)(tong)風(feng)管(guan)(guan)，并(bing)在逐(zhu)步取代防腐(fu)(fu)性(xing)(xing)能差的鍍鋅鐵(tie)皮通(tong)(tong)風(feng)管(guan)(guan)。尤其是(shi)在濕度大的地(di)下工(gong)程(cheng)和長江以南地(di)區(qu)，它(ta)(ta)的優越性(xing)(xing)更(geng)為(wei)顯著。
通過氯(lv)氧鎂(mei)膠凝材料(liao)的研(yan)究及(ji)制品的檢(jian)測，發現無機玻(bo)璃鋼(gang)通風管在(zai)生產(chan)中及(ji)工(gong)程應用中仍(reng)存在(zai)一些質量問題(ti)。有的質量問題(ti)嚴重(zhong)影響了工(gong)程的使用壽(shou)命，應引起(qi)大家足夠重(zhong)視。
