無機(ji)玻璃鋼通風管(guan)
無機玻(bo)(bo)璃鋼(gang)通風管(又稱(cheng)玻(bo)(bo)璃纖維氯氧(yang)鎂水泥通風管)是(shi)以(yi)氯氧(yang)鎂水泥為(wei)膠結料中(zhong)(zhong)堿玻(bo)(bo)璃纖維為(wei)增強材(cai)料、加入(ru)填充(chong)材(cai)料和改性劑等所制成的(de)一種(zhong)管材(cai)。它具有(you)不(bu)燃燒、屬不(bu)燃材(cai)料A級,耐腐蝕、強度高和重(zhong)量輕等特點。在建(jian)筑工(gong)(gong)(gong)程(cheng)、地(di)下工(gong)(gong)(gong)程(cheng)及工(gong)(gong)(gong)業廠房的(de)通風中(zhong)(zhong),它已(yi)經完全(quan)取代了不(bu)耐燃的(de)有(you)機玻(bo)(bo)璃鋼(gang)通風管,并在逐步取代防腐性能差的(de)鍍鋅鐵(tie)皮(pi)通風管。尤其是(shi)在濕度大的(de)地(di)下工(gong)(gong)(gong)程(cheng)和長江以(yi)南地(di)區,它的(de)優越(yue)性更為(wei)顯(xian)著(zhu)。
通過氯氧鎂膠凝(ning)材料的研究及(ji)制品(pin)的檢測(ce),發現無機玻璃(li)鋼(gang)通風管(guan)在生(sheng)產(chan)中(zhong)及(ji)工(gong)(gong)程應(ying)用中(zhong)仍存在一些質(zhi)(zhi)量(liang)問(wen)題(ti)。有的質(zhi)(zhi)量(liang)問(wen)題(ti)嚴重影響(xiang)了工(gong)(gong)程的使用壽(shou)命,應(ying)引起(qi)大家足夠重視(shi)。
