聚氨(an)酯(zhi)無縫保溫(wen)(wen)(wen)管(guan)-施(shi)(shi)工中(zhong)常見問題(ti)及(ji)解決辦法 聚氨(an)酯(zhi)蒸汽保溫(wen)(wen)(wen)管(guan)起發速(su)度慢此(ci)現(xian)象一般(ban)出(chu)現(xian)在秋冬季節或早晨施(shi)(shi)工，因(yin)為(wei)氣(qi)(qi)溫(wen)(wen)(wen)突然降(jiang)低或氣(qi)(qi)溫(wen)(wen)(wen)低所(suo)致(zhi)。將環境溫(wen)(wen)(wen)度、黑料(liao)溫(wen)(wen)(wen)度升(sheng)高即可(ke)解決。一般(ban)將黑料(liao)溫(wen)(wen)(wen)度升(sheng)至30－60℃，環境溫(wen)(wen)(wen)度升(sheng)至20－30℃即可(ke)。 聚氨(an)酯(zhi)保溫(wen)(wen)(wen)管(guan)起發速(su)度快此(ci)現(xian)象一般(ban)出(chu)現(xian)在春夏季節或中(zhong)午施(shi)(shi)工，因(yin)為(wei)氣(qi)(qi)溫(wen)(wen)(wen)突然升(sheng)高事氣(qi)(qi)
聚(ju)氨酯(zhi)(zhi)無縫保溫(wen)管-施工(gong)中(zhong)常見(jian)問(wen)題及解(jie)(jie)決(jue)辦法 聚(ju)氨酯(zhi)(zhi)蒸汽保溫(wen)管起發速(su)度(du)慢此現(xian)(xian)(xian)(xian)象(xiang)一(yi)(yi)般出現(xian)(xian)(xian)(xian)在(zai)秋(qiu)冬季節或(huo)早晨施工(gong)，因為氣(qi)溫(wen)突然(ran)降低或(huo)氣(qi)溫(wen)低所致。將環境溫(wen)度(du)、黑(hei)料(liao)(liao)溫(wen)度(du)升(sheng)高即可解(jie)(jie)決(jue)。一(yi)(yi)般將黑(hei)料(liao)(liao)溫(wen)度(du)升(sheng)至30－60℃，環境溫(wen)度(du)升(sheng)至20－30℃即可。 聚(ju)氨酯(zhi)(zhi)保溫(wen)管起發速(su)度(du)快(kuai)此現(xian)(xian)(xian)(xian)象(xiang)一(yi)(yi)般出現(xian)(xian)(xian)(xian)在(zai)春夏季節或(huo)中(zhong)午施工(gong)，因為氣(qi)溫(wen)突然(ran)升(sheng)高事氣(qi)溫(wen)太所致。可將黑(hei)料(liao)(liao)用冷水泠卻或(huo)夜(ye)間放(fang)在(zai)室外自然(ran)冷卻，避(bi)免太陽直曬。 聚(ju)氨酯(zhi)(zhi)保溫(wen)管泡(pao)沫強度(du)較小且泡(pao)沬較軟此現(xian)(xian)(xian)(xian)象(xiang)由(you)黑(hei)白料(liao)(liao)比(bi)(bi)例失調引起，適當增大黑(hei)料(liao)(liao)比(bi)(bi)例即可（1：1—1.05）注意不在(zai)使(shi)黑(hei)料(liao)(liao)比(bi)(bi)例太大，否(fou)則(ze)，會(hui)使(shi)泡(pao)沬變脆(cui)，亦影響泡(pao)沬性能。
