盡管(guan)(guan)傳統(tong)架(jia)空(kong)保(bao)(bao)(bao)溫(wen)(wen)管(guan)(guan)有著制(zhi)(zhi)作(zuo)工(gong)(gong)序(xu)簡單，技術難度(du)低的(de)(de)優點(dian)，但(dan)在(zai)(zai)節能(neng)減排愈發(fa)重要的(de)(de)今天(tian)，人們對保(bao)(bao)(bao)溫(wen)(wen)管(guan)(guan)保(bao)(bao)(bao)溫(wen)(wen)性(xing)能(neng)的(de)(de)要求日益提高。同時(shi)(shi)，隨著我國經濟(ji)的(de)(de)發(fa)展，人工(gong)(gong)成本普遍上漲，長工(gong)(gong)期、高成本的(de)(de)現場(chang)安裝制(zhi)(zhi)作(zuo)方法的(de)(de)越來越不(bu)適應時(shi)(shi)代。因此，本文介(jie)紹一種新型(xing)的(de)(de)預(yu)制(zhi)(zhi)架(jia)空(kong)保(bao)(bao)(bao)溫(wen)(wen)管(guan)(guan)。預(yu)制(zhi)(zhi)架(jia)空(kong)保(bao)(bao)(bao)溫(wen)(wen)管(guan)(guan)與(yu)傳統(tong)架(jia)空(kong)保(bao)(bao)(bao)溫(wen)(wen)管(guan)(guan)更大的(de)(de)不(bu)同在(zai)(zai)于預(yu)制(zhi)(zhi)保(bao)(bao)(bao)溫(wen)(wen)管(guan)(guan)的(de)(de)工(gong)(gong)作(zuo)管(guan)(guan)與(yu)保(bao)(bao)(bao)溫(wen)(wen)層均在(zai)(zai)工(gong)(gong)廠內制(zhi)(zhi)造完成，現場(chang)施工(gong)(gong)僅僅需要將各節加(jia)工(gong)(gong)完成的(de)(de)保(bao)(bao)(bao)溫(wen)(wen)管(guan)(guan)安裝連接(jie)，不(bu)必(bi)在(zai)(zai)現場(chang)進行保(bao)(bao)(bao)溫(wen)(wen)材料的(de)(de)敷設。

傳統架空(kong)保(bao)溫(wen)(wen)(wen)管(guan)的(de)硬(ying)(ying)(ying)質(zhi)保(bao)溫(wen)(wen)(wen)材料(liao)在現(xian)(xian)場環境(jing)溫(wen)(wen)(wen)度下進(jin)行(xing)(xing)安(an)裝，當工(gong)作管(guan)達到運行(xing)(xing)溫(wen)(wen)(wen)度時硬(ying)(ying)(ying)質(zhi)保(bao)溫(wen)(wen)(wen)材料(liao)間出現(xian)(xian)縫(feng)隙增(zeng)大(da)的(de)問題。此(ci)種新型(xing)預制保(bao)溫(wen)(wen)(wen)管(guan)在工(gong)廠內安(an)裝硬(ying)(ying)(ying)質(zhi)保(bao)溫(wen)(wen)(wen)材料(liao)，便于安(an)裝時嚴格把控嵌縫(feng)工(gong)作。之后，將(jiang)安(an)裝好硬(ying)(ying)(ying)質(zhi)保(bao)溫(wen)(wen)(wen)層的(de)半成(cheng)品管(guan)道直接放入(ru)聚氨酯(zhi)泡沫的(de)成(cheng)型(xing)模具中，注入(ru)原(yuan)料(liao)混(hun)合(he)液進(jin)行(xing)(xing)發泡，硬(ying)(ying)(ying)質(zhi)泡沫成(cheng)型(xing)后脫模。此(ci)種制作方法可將(jiang)縫(feng)隙完(wan)全包裹，使得外(wai)保(bao)溫(wen)(wen)(wen)層和硬(ying)(ying)(ying)保(bao)溫(wen)(wen)(wen)層成(cheng)為(wei)一個(ge)整(zheng)體，相(xiang)比傳統架空(kong)管(guan)的(de)制作方法可減少縫(feng)隙間的(de)漏熱，大(da)大(da)提高整(zheng)體保(bao)溫(wen)(wen)(wen)性能。
