熱鍍鋅管是使(shi)熔融(rong)金(jin)(jin)屬與(yu)鐵基體(ti)(ti)反應而(er)產生(sheng)合金(jin)(jin)層，從而(er)使(shi)基體(ti)(ti)和(he)鍍(du)(du)層二者相結(jie)合。熱(re)鍍(du)(du)鋅(xin)(xin)(xin)是先將鋼管(guan)(guan)(guan)進行酸洗(xi)，為了去除鋼管(guan)(guan)(guan)表面的(de)氧化(hua)鐵，酸洗(xi)后，通過氯(lv)化(hua)銨(an)或氯(lv)化(hua)鋅(xin)(xin)(xin)水溶(rong)液或氯(lv)化(hua)銨(an)和(he)氯(lv)化(hua)鋅(xin)(xin)(xin)混(hun)合水溶(rong)液槽(cao)中(zhong)進行清(qing)洗(xi)，然后送入熱(re)浸鍍(du)(du)槽(cao)中(zhong)。熱(re)鍍(du)(du)鋅(xin)(xin)(xin)具有鍍(du)(du)層均勻，附著力強，使(shi)用壽(shou)命(ming)長(chang)等優點(dian)。熱(re)鍍(du)(du)鋅(xin)(xin)(xin)鋼管(guan)(guan)(guan)基體(ti)(ti)。鍍(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)(guan)與(yu)熔融(rong)的(de)鍍(du)(du)液發生(sheng)復雜的(de)物(wu)理、化(hua)學反應，形成耐腐蝕的(de)結(jie)構緊密的(de)鋅(xin)(xin)(xin)一鐵合金(jin)(jin)層。合金(jin)(jin)層與(yu)純鋅(xin)(xin)(xin)層、鋼管(guan)(guan)(guan)基體(ti)(ti)融(rong)為一體(ti)(ti)，故其耐腐蝕能力強。

鍍鋅方管廠家解析什么是鍍鋅鋼管？

冷(leng)(leng)(leng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)管(guan)(guan)就是電(dian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)，鍍(du)(du)鋅(xin)(xin)(xin)(xin)量很少(shao)，只(zhi)有(you)10－50g/m2，其本身(shen)的(de)(de)耐腐(fu)蝕性比熱(re)鍍(du)(du)鋅(xin)(xin)(xin)(xin)管(guan)(guan)相(xiang)差很多。正規的(de)(de)鍍(du)(du)鋅(xin)(xin)(xin)(xin)管(guan)(guan)生產廠(chang)家，為(wei)了保證質量，大多不(bu)采(cai)用(yong)(yong)電(dian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)（冷(leng)(leng)(leng)鍍(du)(du)）。只(zhi)有(you)那(nei)些規模小、設備陳舊的(de)(de)小企業采(cai)用(yong)(yong)電(dian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)，當然他們的(de)(de)價格也相(xiang)對便宜一些。建設部(bu)已正式(shi)下文，淘汰技術(shu)落后的(de)(de)冷(leng)(leng)(leng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)管(guan)(guan)，不(bu)準用(yong)(yong)冷(leng)(leng)(leng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)管(guan)(guan)作(zuo)水(shui)、煤氣(qi)管(guan)(guan)。 冷(leng)(leng)(leng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)管(guan)(guan)鍍(du)(du)鋅(xin)(xin)(xin)(xin)層(ceng)是電(dian)鍍(du)(du)層(ceng)，鋅(xin)(xin)(xin)(xin)層(ceng)與(yu)鋼(gang)(gang)(gang)管(guan)(guan)基體獨立分層(ceng)。鋅(xin)(xin)(xin)(xin)層(ceng)較薄，鋅(xin)(xin)(xin)(xin)層(ceng)簡(jian)單附(fu)著(zhu)在鋼(gang)(gang)(gang)管(guan)(guan)基體上，容(rong)易脫落。故(gu)其耐腐(fu)蝕性能差。在新建住宅中，禁止使用(yong)(yong)冷(leng)(leng)(leng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)管(guan)(guan)作(zuo)為(wei)給水(shui)管(guan)(guan)。
