鍍鋅管的分類及生產工藝流程是什么？
關于鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)分熱(re)(re)鍍(du)(du)鋅(xin)(xin)鋼管(guan)(guan)(guan)和冷鍍(du)(du)鋅(xin)(xin)鋼管(guan)(guan)(guan)，其中冷鍍(du)(du)鋅(xin)(xin)鋼管(guan)(guan)(guan)已被(bei)逐(zhu)漸淘(tao)汰(tai)使(shi)用。1、熱(re)(re)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)/熱(re)(re)鍍(du)(du)鋅(xin)(xin)鋼管(guan)(guan)(guan)熱(re)(re)鍍(du)(du)鋅(xin)(xin)是(shi)使(shi)熔(rong)融金屬與鐵(tie)基體反應而產生合金層(ceng)，從而使(shi)基體和鍍(du)(du)層(ceng)二者(zhe)相結合。熱(re)(re)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)的制造是(shi)先將鋼管(guan)(guan)(guan)進(jin)行酸洗(xi)，用來(lai)去除(chu)鋼管(guan)(guan)(guan)表(biao)面的氧化鐵(tie)，酸洗(xi)后(hou)，通過(guo)氯(lv)(lv)化銨(an)或氯(lv)(lv)化鋅(xin)(xin)水溶液或氯(lv)(lv)化銨(an)和氯(lv)(lv)化鋅(xin)(xin)混合水溶液槽中進(jin)行清洗(xi)，然后(hou)
