盡(jin)管(guan)(guan)(guan)傳(chuan)統架(jia)空保(bao)溫管(guan)(guan)(guan)有(you)著(zhu)(zhu)制作(zuo)工序簡單，技術難度低的優點，但在節能減排愈發重要的今(jin)天，人們(men)對保(bao)溫管(guan)(guan)(guan)保(bao)溫性能的要求日益提高。同時，隨著(zhu)(zhu)我國(guo)經濟的發展(zhan)，人工成(cheng)(cheng)本普遍(bian)上(shang)漲，長工期(qi)、高成(cheng)(cheng)本的現(xian)場(chang)安裝(zhuang)制作(zuo)方法的越(yue)來越(yue)不(bu)適應時代。因此，本文介紹一種新型的預(yu)制架(jia)空保(bao)溫管(guan)(guan)(guan)。預(yu)制架(jia)空保(bao)溫管(guan)(guan)(guan)與傳(chuan)統架(jia)空保(bao)溫管(guan)(guan)(guan)更大(da)的不(bu)同在于預(yu)制保(bao)溫管(guan)(guan)(guan)的工作(zuo)管(guan)(guan)(guan)與保(bao)溫層均(jun)在工廠內制造完成(cheng)(cheng)，現(xian)場(chang)施工僅僅需要將(jiang)各節加工完成(cheng)(cheng)的保(bao)溫管(guan)(guan)(guan)安裝(zhuang)連接，不(bu)必在現(xian)場(chang)進行(xing)保(bao)溫材料的敷設。

傳(chuan)統(tong)架(jia)空保(bao)(bao)(bao)(bao)(bao)溫(wen)管(guan)(guan)的(de)(de)(de)(de)(de)硬質(zhi)(zhi)保(bao)(bao)(bao)(bao)(bao)溫(wen)材(cai)料(liao)在(zai)現場(chang)環境溫(wen)度下(xia)進行(xing)安裝，當工作管(guan)(guan)達到運行(xing)溫(wen)度時(shi)硬質(zhi)(zhi)保(bao)(bao)(bao)(bao)(bao)溫(wen)材(cai)料(liao)間(jian)出(chu)現縫(feng)(feng)隙(xi)增(zeng)大(da)的(de)(de)(de)(de)(de)問題(ti)。此種(zhong)新型預(yu)制保(bao)(bao)(bao)(bao)(bao)溫(wen)管(guan)(guan)在(zai)工廠內安裝硬質(zhi)(zhi)保(bao)(bao)(bao)(bao)(bao)溫(wen)材(cai)料(liao)，便于(yu)安裝時(shi)嚴格把控嵌縫(feng)(feng)工作。之(zhi)后(hou)(hou)，將安裝好硬質(zhi)(zhi)保(bao)(bao)(bao)(bao)(bao)溫(wen)層(ceng)的(de)(de)(de)(de)(de)半(ban)成(cheng)品管(guan)(guan)道直接(jie)放入聚氨酯泡沫的(de)(de)(de)(de)(de)成(cheng)型模具中，注入原(yuan)料(liao)混合液進行(xing)發(fa)泡，硬質(zhi)(zhi)泡沫成(cheng)型后(hou)(hou)脫模。此種(zhong)制作方法可(ke)將縫(feng)(feng)隙(xi)完全包裹，使得外保(bao)(bao)(bao)(bao)(bao)溫(wen)層(ceng)和硬保(bao)(bao)(bao)(bao)(bao)溫(wen)層(ceng)成(cheng)為一個整體，相比(bi)傳(chuan)統(tong)架(jia)空管(guan)(guan)的(de)(de)(de)(de)(de)制作方法可(ke)減少(shao)縫(feng)(feng)隙(xi)間(jian)的(de)(de)(de)(de)(de)漏(lou)熱，大(da)大(da)提高整體保(bao)(bao)(bao)(bao)(bao)溫(wen)性(xing)能。
