防(fang)水保溫(wen)(wen)一體化材(cai)料既能(neng)防(fang)水.又(you)有良好的隔熱保溫(wen)(wen)性能(neng).聚氨醋硬泡(pao)體防(fang)水保溫(wen)(wen)材(cai)料就屬此類。
聚氮醋(cu)硬泡(pao)體(ti)簡稱PUR,是由兩(liang)種(zhong)液態(tai)成(cheng)分組成(cheng)的,其中A組分為多元(yuan)醇;B組分為異(yi)氫酸酯(MDI)。采用無氟發泡(pao)技術.使用專用噴(pen)(pen)涂(tu)(tu)設(she)備(bei),在工(gong)(gong)程現場(chang)作業(ye),連(lian)續噴(pen)(pen)涂(tu)(tu)施(shi)工(gong)(gong)完(wan)成(cheng),產生閉孔率(lv)不低(di)于95%的硬泡(pao)體(ti)化(hua)合物(PUR).噴(pen)(pen)涂(tu)(tu)施(shi)工(gong)(gong)完(wan)成(cheng)后,在施(shi)工(gong)(gong)作業(ye)面(mian)上(shang)可(ke)按需要(yao)形成(cheng)一(yi)層不同(tong)厚(hou)度、無接縫的連(lian)續殼(ke)體(ti),在殼(ke)體(ti)的表面(mian)同(tong)時噴(pen)(pen)涂(tu)(tu)一(yi)層防(fang)(fang)紫外(wai)線的防(fang)(fang)護(hu)層。根(gen)據各地區對(dui)建筑保(bao)沮(ju)隔熱的不同(tong)要(yao)求,對(dui)PUR防(fang)(fang)水(shui)保(bao)溫層的厚(hou)度可(ke)分為25mm,30mm,40mm三個(ge)厚(hou)度等級.
聚(ju)氨(an)酯(zhi)硬泡體(ti)防水(shui)(shui)(shui)保(bao)溫(wen)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)技術(shu)(shu),是(shi)一(yi)種集防水(shui)(shui)(shui)與保(bao)溫(wen)隔(ge)熱性(xing)能(neng)于一(yi)體(ti)的(de)(de)、現場連續噴涂施工(gong)(gong)(gong)的(de)(de)技術(shu)(shu),無論在(zai)材料性(xing)能(neng)方(fang)面(mian).還是(shi)在(zai)設(she)計、施工(gong)(gong)(gong)、驗收、維修等方(fang)面(mian),都與現行的(de)(de)防水(shui)(shui)(shui)與保(bao)溫(wen)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)有很(hen)大差異,為使PUR防水(shui)(shui)(shui)保(bao)溫(wen)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)技術(shu)(shu)在(zai)實際應用中有法可(ke)依,確保(bao)防水(shui)(shui)(shui)、保(bao)溫(wen)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)質量(liang),標準《聚(ju)氨(an)酷硬泡體(ti)防水(shui)(shui)(shui)保(bao)溫(wen)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)技術(shu)(shu)規(gui)程(cheng)(cheng)(cheng))JC14-1999,對該材料的(de)(de)防水(shui)(shui)(shui)性(xing)能(neng)、保(bao)沮隔(ge)熱性(xing)能(neng)、密度(du)、強度(du)等提出了具體(ti)的(de)(de)指標要(yao)求.
