鍍鋅管的分類及生產工藝流程是什么？
關于鍍(du)(du)鋅管(guan)(guan)(guan)(guan)分熱(re)鍍(du)(du)鋅鋼(gang)(gang)管(guan)(guan)(guan)(guan)和(he)冷(leng)鍍(du)(du)鋅鋼(gang)(gang)管(guan)(guan)(guan)(guan)，其中冷(leng)鍍(du)(du)鋅鋼(gang)(gang)管(guan)(guan)(guan)(guan)已被逐漸淘汰使用(yong)(yong)。1、熱(re)鍍(du)(du)鋅管(guan)(guan)(guan)(guan)/熱(re)鍍(du)(du)鋅鋼(gang)(gang)管(guan)(guan)(guan)(guan)熱(re)鍍(du)(du)鋅是使熔融(rong)金屬與(yu)鐵(tie)基體(ti)(ti)反應(ying)而(er)(er)產生合金層，從(cong)而(er)(er)使基體(ti)(ti)和(he)鍍(du)(du)層二者相結合。熱(re)鍍(du)(du)鋅管(guan)(guan)(guan)(guan)的(de)制造是先將鋼(gang)(gang)管(guan)(guan)(guan)(guan)進行酸洗，用(yong)(yong)來去(qu)除鋼(gang)(gang)管(guan)(guan)(guan)(guan)表面的(de)氧化(hua)(hua)(hua)鐵(tie)，酸洗后(hou)，通過氯(lv)化(hua)(hua)(hua)銨或氯(lv)化(hua)(hua)(hua)鋅水(shui)溶(rong)液(ye)或氯(lv)化(hua)(hua)(hua)銨和(he)氯(lv)化(hua)(hua)(hua)鋅混合水(shui)溶(rong)液(ye)槽中進行清(qing)洗，然后(hou)
