攪拌站風冷螺桿式冷水機

混(hun)凝(ning)(ning)(ning)(ning)(ning)士攪(jiao)(jiao)拌(ban)站(zhan)(zhan)風冷(leng)螺桿(gan)式(shi)冷(leng)水(shui)(shui)機(ji)，簡(jian)稱(cheng)攪(jiao)(jiao)拌(ban)站(zhan)(zhan)冷(leng)水(shui)(shui)機(ji)。攪(jiao)(jiao)拌(ban)站(zhan)(zhan)冷(leng)水(shui)(shui)機(ji)一種(zhong)專門用(yong)(yong)于工(gong)程(cheng)混(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)的(de)攪(jiao)(jiao)拌(ban)使用(yong)(yong)。在(zai)公(gong)路橋，高(gao)架橋的(de)建設中，對混(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)的(de)要(yao)求非常高(gao)，然而當(dang)混(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)澆筑后，在(zai)硬化(hua)(hua)(hua)(hua)的(de)過程(cheng)中，水(shui)(shui)泥水(shui)(shui)化(hua)(hua)(hua)(hua)時，會產(chan)生大量(liang)(liang)的(de)水(shui)(shui)化(hua)(hua)(hua)(hua)熱(re)(re)，但由于混(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)的(de)體積很(hen)(hen)大，大量(liang)(liang)的(de)水(shui)(shui)化(hua)(hua)(hua)(hua)熱(re)(re)容易(yi)積聚在(zai)混(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)內(nei)部(bu)(bu)散發不(bu)出來，導致內(nei)部(bu)(bu)溫(wen)(wen)(wen)度(du)急劇升高(gao)。可是混(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)表(biao)面(mian)散熱(re)(re)又很(hen)(hen)快(kuai)，這(zhe)就造(zao)成(cheng)混(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)內(nei)外出現較大的(de)溫(wen)(wen)(wen)差(cha)，這(zhe)個溫(wen)(wen)(wen)差(cha)會造(zao)成(cheng)內(nei)部(bu)(bu)與外部(bu)(bu)熱(re)(re)脹冷(leng)縮的(de)程(cheng)度(du)不(bu)同，使混(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)表(biao)面(mian)產(chan)生一定(ding)的(de)拉(la)應力。所以混(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)在(zai)攪(jiao)(jiao)拌(ban)時使用(yong)(yong)低(di)溫(wen)(wen)(wen)水(shui)(shui)來攪(jiao)(jiao)拌(ban)就要(yao)解(jie)決這(zhe)個問(wen)題，使混(hun)凝(ning)(ning)(ning)(ning)(ning)土(tu)(tu)(tu)在(zai)結構硬化(hua)(hua)(hua)(hua)后硬度(du)和強度(du)更(geng)高(gao)。
