無機(ji)玻璃鋼通風管
無(wu)機玻璃(li)鋼(gang)通(tong)(tong)(tong)風管(guan)(又稱玻璃(li)纖維(wei)氯氧鎂水(shui)泥通(tong)(tong)(tong)風管(guan))是以氯氧鎂水(shui)泥為(wei)膠結料中堿玻璃(li)纖維(wei)為(wei)增強材料、加入填充材料和(he)改性劑等所制(zhi)成的(de)一種管(guan)材。它(ta)(ta)具有不(bu)燃(ran)燒、屬不(bu)燃(ran)材料A級,耐腐蝕、強度高和(he)重(zhong)量(liang)輕等特點。在建(jian)筑(zhu)工(gong)(gong)(gong)程、地下工(gong)(gong)(gong)程及工(gong)(gong)(gong)業(ye)廠房(fang)的(de)通(tong)(tong)(tong)風中,它(ta)(ta)已(yi)經完全取代了(le)不(bu)耐燃(ran)的(de)有機玻璃(li)鋼(gang)通(tong)(tong)(tong)風管(guan),并在逐步取代防腐性能差的(de)鍍(du)鋅鐵皮(pi)通(tong)(tong)(tong)風管(guan)。尤其是在濕度大(da)的(de)地下工(gong)(gong)(gong)程和(he)長江以南地區(qu),它(ta)(ta)的(de)優越(yue)性更為(wei)顯著。
通(tong)過氯(lv)氧鎂膠(jiao)凝材料(liao)的(de)研究(jiu)及制品的(de)檢測,發現無機(ji)玻璃鋼通(tong)風管在生產中(zhong)及工(gong)程(cheng)應用中(zhong)仍存(cun)在一些質量問(wen)題(ti)。有的(de)質量問(wen)題(ti)嚴重影響了工(gong)程(cheng)的(de)使用壽命,應引起大家足夠(gou)重視。
