無機(ji)玻璃(li)鋼通風管
無機(ji)玻璃(li)鋼(gang)通(tong)(tong)風管(guan)(又稱玻璃(li)纖(xian)維(wei)氯氧鎂水泥通(tong)(tong)風管(guan))是(shi)以氯氧鎂水泥為膠結料(liao)中(zhong)堿玻璃(li)纖(xian)維(wei)為增強材(cai)料(liao)、加入填充材(cai)料(liao)和改性(xing)劑等所制(zhi)成的(de)一種管(guan)材(cai)。它具(ju)有(you)不燃燒、屬不燃材(cai)料(liao)A級,耐腐蝕、強度(du)高和重量輕等特點。在(zai)建筑工(gong)程、地(di)下工(gong)程及工(gong)業廠房的(de)通(tong)(tong)風中(zhong),它已經(jing)完(wan)全取(qu)代了不耐燃的(de)有(you)機(ji)玻璃(li)鋼(gang)通(tong)(tong)風管(guan),并在(zai)逐步取(qu)代防腐性(xing)能差的(de)鍍鋅鐵(tie)皮通(tong)(tong)風管(guan)。尤其是(shi)在(zai)濕度(du)大的(de)地(di)下工(gong)程和長江以南(nan)地(di)區,它的(de)優越性(xing)更為顯著。
通(tong)過氯氧鎂膠凝材料(liao)的研究及(ji)(ji)制品的檢測(ce),發現(xian)無機玻璃鋼通(tong)風管在(zai)生(sheng)產(chan)中及(ji)(ji)工(gong)(gong)程應(ying)用中仍存在(zai)一(yi)些質(zhi)量問題。有(you)的質(zhi)量問題嚴重(zhong)(zhong)影響了(le)工(gong)(gong)程的使用壽命(ming),應(ying)引起大家(jia)足夠重(zhong)(zhong)視(shi)。
