熱熔對接是CPVC管道常用的施工方法之一，該施工方法需要借助CPVC熱熔對接焊機進行操作。實際安裝施工中，因為焊接技術掌握不準確，造成焊接口開裂的情況時有發生。下面總結了工業CPVC管道熱熔對接焊接口開裂的原因以及預防措施，供大家參考：

1熱溶掛接的壓力過大，會造成焊接生產不牢靠

熱熔(rong)(rong)連接指導時，焊(han)機壓為過研討會可能會導致熔(rong)(rong)融(rong)層(ceng)擠壓出(chu)，印象(xiang)熔(rong)(rong)融(rong)結果。

優秀的(de)焊結口：直接頭應含有沿PE管整體的(de)圓心圓滑等勢(shi)面的(de)不光(guang)滑翻(fan)邊，翻(fan)邊更低處不能不高(gao)于PE管外層。

2電弧補焊水溫發現異常，有電弧補焊口不穩固

補(bu)焊濕(shi)度過(guo)高，會致使CPVC文件(jian)分子結構(gou)氫氟酸(suan)處理(li)，損失彈(dan)性(xing)；補(bu)焊濕(shi)度過(guo)低(di)，則沒有辦法充分的熔融，并不能完成有郊凝固。

引起不銹(xiu)鋼(gang)焊接溫度(du)因(yin)素異(yi)常情況的其原因(yin)有：

1.的使(shi)用工作人員對氬弧焊(han)室溫(wen)不學習(xi)，促使(shi)控(kong)制(zhi)在氬弧焊(han)室溫(wen)不正確。CPVC供水管道熱熔膠銜接合適(shi)的使(shi)用室溫(wen)是(shi)220℃±10℃。

2.恒溫(wen)儀或熱(re)(re)電偶熱(re)(re)度計(ji)受(shou)損(sun)，有焊(han)(han)(han)(han)機(ji)恒溫(wen)儀提示 熱(re)(re)度與燒(shao)水板(ban)真(zhen)實效果熱(re)(re)度不(bu)同一，焊(han)(han)(han)(han)加工(gong)熱(re)(re)度非常(chang)。故建(jian)議大(da)家在焊(han)(han)(han)(han)機(ji)用(yong)到(dao)(dao)前，用(yong)到(dao)(dao)產(chan)業熱(re)(re)度計(ji)先量測燒(shao)水板(ban)真(zhen)實效果熱(re)(re)度，衡量焊(han)(han)(han)(han)加工(gong)熱(re)(re)度的最正(zheng)確性。

3一系列冷卻策略不規范性，構成電焊焊接不牢靠

1.春秋季超高(gao)溫(wen)環(huan)保(bao)中脂肪(fang)含量(liang)散(san)掉(diao)過快，悍(han)(han)接口溫(wen)度一秒(miao)有效降低(di)，易容(rong)(rong)易容(rong)(rong)易造成CPVC分子式(shi)鏈開裂，悍(han)(han)接不經久耐用(yong)(yong)。CPVC排水管道悍(han)(han)接對環(huan)保(bao)溫(wen)度條(tiao)件為-5℃-40℃, -5℃下述環(huan)保(bao)內使用(yong)(yong)需利用(yong)(yong)架設簡宜防塵、防風(feng)棚、棉被子保(bao)溫(wen)等的(de)(de)方(fang)法(fa)，打造滿足(zu)條(tiao)件的(de)(de)使用(yong)(yong)環(huan)保(bao)。另一悍(han)(han)接口要盡量(liang)避免(mian)水、風(feng)、臟(zang)污的(de)(de)入侵(qin)，容(rong)(rong)易容(rong)(rong)易造成不銹鋼(gang)裝飾管的(de)(de)虛焊。

2.冷凝(ning)周期缺陷，管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)塑料(liao)(liao)管(guan)(guan)(guan)(guan)道(dao)(dao)接(jie)頭(tou)尚位于熔融(rong)方式，兩管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)塑料(liao)(liao)管(guan)(guan)(guan)(guan)道(dao)(dao)未(wei)壓(ya)根冷凝(ning)即(ji)挪動管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)塑料(liao)(liao)管(guan)(guan)(guan)(guan)道(dao)(dao)，產生(sheng)管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)塑料(liao)(liao)管(guan)(guan)(guan)(guan)道(dao)(dao)崩裂(lie)。氬弧焊到位后(hou)，管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)塑料(liao)(liao)管(guan)(guan)(guan)(guan)道(dao)(dao)的冷凝(ning)周期為管(guan)(guan)(guan)(guan)壁（mm）*1min，單獨也(ye)是(shi)要(yao)(yao)(yao)需(xu)要(yao)(yao)(yao)考慮環境溫暖重要(yao)(yao)(yao)因素的影(ying)響到，管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)塑料(liao)(liao)管(guan)(guan)(guan)(guan)道(dao)(dao)未(wei)壓(ya)根冷凝(ning)不(bu)要(yao)(yao)(yao)挪動管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)管(guan)(guan)(guan)(guan)件(jian)(jian)(jian)(jian)塑料(liao)(liao)管(guan)(guan)(guan)(guan)道(dao)(dao)。
