加工DN300給水地埋聚氨酯保溫管

聚氨(an)酯保(bao)溫管(guan)具(ju)有(you)容重輕,強度高,絕熱,隔音,阻燃,耐(nai)寒,防腐(fu),不吸水(shui),施工(gong)簡(jian)便快捷(jie)等(deng)(deng)特(te)點,已(yi)成為建筑,運(yun)輸,石油,化(hua)工(gong),電(dian)力(li),冷(leng)藏等(deng)(deng)工(gong)業(ye)部門(men)絕熱保(bao)溫,防水(shui)堵(du)漏(lou),密封等(deng)(deng)材料。聚氨(an)酯保(bao)溫管(guan)是以高功能(neng)聚醚多元醇組合(he)料和多次甲基多苯基多異(yi)氰酸酯為原料經化(hua)學反(fan)應(ying)發泡(pao)而(er)成。聚氨(an)酯保(bao)溫管(guan)用于(yu)室內外各(ge)種管(guan)道(dao),集(ji)中供(gong)熱管(guan)道(dao),中央空調管(guan)道(dao),化(hua)工(gong),醫(yi)藥等(deng)(deng)工(gong)業(ye)管(guan)道(dao)的(de)保(bao)溫,保(bao)冷(leng)工(gong)程。

聚(ju)氨(an)酯發泡(pao)(pao)(pao)保溫鋼管由于聚(ju)氨(an)酯硬質泡(pao)(pao)(pao)沫保溫層緊密(mi)地粘結(jie)在(zai)鋼管外(wai)皮,隔絕了空氣和水的滲入,能起到良(liang)好的防(fang)腐(fu)作(zuo)用。同時它的發泡(pao)(pao)(pao)孔都是閉(bi)合的,吸水性(xing)很(hen)小。高密(mi)度(du)聚(ju)乙烯外(wai)殼,玻璃鋼外(wai)殼均具有良(liang)好的防(fang)腐(fu),絕緣和機(ji)械性(xing)能。

1,高耐火(huo)性

聚氨酯發(fa)泡(pao)保(bao)溫管是無機材料(liao)(liao),屬(shu)防火材料(liao)(liao),從(cong)而具有良好的耐(nai)火性,耐(nai)火度達到(dao)1000℃以上,滿足了外墻保(bao)溫板的耐(nai)火要求。

2,高保溫(wen)隔熱性(xing)

聚(ju)氨酯發泡保溫管(guan)的閉(bi)孔率＞95%,高閉(bi)孔率使空氣流動(dong)造成的熱傳(chuan)遞低,是高隔熱的先(xian)決(jue)條件。因此生產的外墻(qiang)保溫板導熱系數達(da)到0.045—0.068W/m.k,比聚(ju)苯板的導熱系數略低,但在實際工程中的使用效果基(ji)本相當,可滿足建筑(zhu)保溫隔熱需要。

3,強度相(xiang)對好,不易(yi)碎裂

聚氨(an)酯發泡(pao)保(bao)溫管抗(kang)壓(ya)抗(kang)折強度(du)均較高,達到了(le)相對統一(yi),使用與運輸(shu)均不(bu)易碎裂,并符合耐(nai)火完整性(xing)。

4,質輕粘結強度高

質輕是我們產品的又一(yi)優勢。密度在(zai)120—320kg/m3,能達到外(wai)墻(qiang)保溫板的各項要求,成本(ben)低。材料的兼容性好,與墻(qiang)體的粘結力強(qiang)。

5,聚氨酯(zhi)發泡保溫鋼管安(an)全。
