無機玻(bo)璃鋼通風(feng)管
無機玻(bo)璃鋼(gang)通(tong)(tong)(tong)風管（又稱玻(bo)璃纖維(wei)(wei)氯氧鎂水泥通(tong)(tong)(tong)風管）是以氯氧鎂水泥為(wei)膠結料(liao)(liao)(liao)中(zhong)(zhong)堿玻(bo)璃纖維(wei)(wei)為(wei)增強(qiang)材料(liao)(liao)(liao)、加入填充材料(liao)(liao)(liao)和(he)改性(xing)(xing)劑等所制成(cheng)的一種管材。它具有不燃燒(shao)、屬不燃材料(liao)(liao)(liao)A級，耐腐(fu)蝕、強(qiang)度高和(he)重量輕等特點。在建筑(zhu)工(gong)(gong)程(cheng)、地(di)下工(gong)(gong)程(cheng)及工(gong)(gong)業廠房的通(tong)(tong)(tong)風中(zhong)(zhong)，它已(yi)經完全(quan)取代了不耐燃的有機玻(bo)璃鋼(gang)通(tong)(tong)(tong)風管，并在逐步取代防腐(fu)性(xing)(xing)能差的鍍鋅鐵(tie)皮通(tong)(tong)(tong)風管。尤(you)其是在濕度大的地(di)下工(gong)(gong)程(cheng)和(he)長江以南地(di)區，它的優越性(xing)(xing)更為(wei)顯著(zhu)。
通(tong)過氯氧鎂膠凝材料的(de)研究及(ji)制(zhi)品的(de)檢測，發現(xian)無機玻璃鋼(gang)通(tong)風(feng)管在生產(chan)中及(ji)工程(cheng)應用(yong)中仍存在一些(xie)質量問題。有的(de)質量問題嚴重影響了工程(cheng)的(de)使用(yong)壽(shou)命，應引(yin)起大家足夠重視。
