無機玻璃鋼通風管
無機(ji)玻(bo)璃鋼通(tong)(tong)風(feng)管(guan)(又稱玻(bo)璃纖維氯氧鎂(mei)(mei)水泥(ni)通(tong)(tong)風(feng)管(guan))是以(yi)(yi)氯氧鎂(mei)(mei)水泥(ni)為膠結料(liao)中(zhong)堿玻(bo)璃纖維為增強材(cai)料(liao)、加入填(tian)充材(cai)料(liao)和改(gai)性(xing)劑等(deng)所制成的(de)一種管(guan)材(cai)。它具(ju)有(you)不(bu)燃燒、屬不(bu)燃材(cai)料(liao)A級(ji),耐腐蝕、強度高(gao)和重量輕等(deng)特點。在(zai)(zai)建(jian)筑工(gong)(gong)程(cheng)(cheng)(cheng)、地(di)下工(gong)(gong)程(cheng)(cheng)(cheng)及(ji)工(gong)(gong)業廠房的(de)通(tong)(tong)風(feng)中(zhong),它已經完全取代了(le)不(bu)耐燃的(de)有(you)機(ji)玻(bo)璃鋼通(tong)(tong)風(feng)管(guan),并在(zai)(zai)逐步取代防腐性(xing)能差的(de)鍍鋅鐵皮通(tong)(tong)風(feng)管(guan)。尤(you)其(qi)是在(zai)(zai)濕度大(da)的(de)地(di)下工(gong)(gong)程(cheng)(cheng)(cheng)和長江(jiang)以(yi)(yi)南地(di)區(qu),它的(de)優越性(xing)更為顯著。
通(tong)過氯氧(yang)鎂(mei)膠凝材料的研究及制品(pin)的檢測,發現無(wu)機玻璃鋼通(tong)風(feng)管在生產中及工(gong)程(cheng)應用中仍存在一些質量問(wen)題。有(you)的質量問(wen)題嚴重(zhong)影響了工(gong)程(cheng)的使用壽命,應引起大家足夠重(zhong)視。
