熱鍍(du)(du)(du)鋅管(guan)是(shi)使熔融金(jin)屬與鐵基體(ti)反應而(er)產生合金(jin)層，從而(er)使基體(ti)和鍍(du)(du)(du)層二者相結合。熱鍍(du)(du)(du)鋅是(shi)先將(jiang)鋼(gang)(gang)管(guan)進行酸洗，為了(le)去除鋼(gang)(gang)管(guan)表面的(de)(de)氧化(hua)(hua)鐵，酸洗后(hou)，通(tong)過(guo)氯化(hua)(hua)銨或氯化(hua)(hua)鋅水溶(rong)液或氯化(hua)(hua)銨和氯化(hua)(hua)鋅混合水溶(rong)液槽中進行清洗，然后(hou)送(song)入(ru)熱浸鍍(du)(du)(du)槽中。熱鍍(du)(du)(du)鋅具有鍍(du)(du)(du)層均勻，附著力強，使用壽命長等優點。鋼(gang)(gang)管(guan)基體(ti)與熔融的(de)(de)鍍(du)(du)(du)液發生復雜的(de)(de)物理(li)

熱(re)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)是使熔(rong)融金(jin)屬與(yu)(yu)鐵(tie)(tie)基體(ti)(ti)反(fan)應(ying)而(er)產生合(he)金(jin)層(ceng)，從而(er)使基體(ti)(ti)和鍍(du)(du)層(ceng)二者相結合(he)。熱(re)鍍(du)(du)鋅(xin)(xin)是先將鋼(gang)管(guan)(guan)(guan)進(jin)行酸(suan)洗(xi)，為了去除鋼(gang)管(guan)(guan)(guan)表面的氧化(hua)(hua)(hua)鐵(tie)(tie)，酸(suan)洗(xi)后，通過氯(lv)(lv)化(hua)(hua)(hua)銨(an)或氯(lv)(lv)化(hua)(hua)(hua)鋅(xin)(xin)水溶(rong)液或氯(lv)(lv)化(hua)(hua)(hua)銨(an)和氯(lv)(lv)化(hua)(hua)(hua)鋅(xin)(xin)混合(he)水溶(rong)液槽中(zhong)進(jin)行清洗(xi)，然后送入熱(re)浸鍍(du)(du)槽中(zhong)。熱(re)鍍(du)(du)鋅(xin)(xin)具(ju)有(you)鍍(du)(du)層(ceng)均(jun)勻，附著力強(qiang)，使用(yong)(yong)(yong)壽(shou)命長(chang)等優點(dian)。鋼(gang)管(guan)(guan)(guan)基體(ti)(ti)與(yu)(yu)熔(rong)融的鍍(du)(du)液發(fa)生復雜(za)(za)的物理、化(hua)(hua)(hua)學反(fan)應(ying)，形成耐(nai)腐蝕(shi)的結構緊(jin)密的鋅(xin)(xin)一鐵(tie)(tie)合(he)金(jin)層(ceng)。合(he)金(jin)層(ceng)與(yu)(yu)純鋅(xin)(xin)層(ceng)、鋼(gang)管(guan)(guan)(guan)基體(ti)(ti)融為一體(ti)(ti)。故其耐(nai)腐蝕(shi)能力強(qiang)。現(xian)在煤氣、大棚，暖氣用(yong)(yong)(yong)的那種鐵(tie)(tie)管(guan)(guan)(guan)也(ye)是鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)，鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)作為水管(guan)(guan)(guan)，管(guan)(guan)(guan)內產生大量(liang)(liang)銹垢，流出的黃水不(bu)僅污染潔(jie)具(ju)，而(er)且夾雜(za)(za)著不(bu)光滑內壁(bi)滋生的細菌，銹蝕(shi)造成水中(zhong)重金(jin)屬含量(liang)(liang)過高，嚴重危害人體(ti)(ti)的健康。六七十年(nian)代，國(guo)際(ji)上發(fa)達國(guo)家開始(shi)開發(fa)新(xin)型(xing)管(guan)(guan)(guan)材，并(bing)陸(lu)續禁(jin)用(yong)(yong)(yong)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)。中(zhong)國(guo)建(jian)設部等四部委也(ye)發(fa)文明確從二000年(nian)起(qi)禁(jin)用(yong)(yong)(yong)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)，目前新(xin)建(jian)小區的冷水管(guan)(guan)(guan)已經(jing)很少使用(yong)(yong)(yong)鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)了，有(you)些(xie)小區的熱(re)水管(guan)(guan)(guan)使用(yong)(yong)(yong)的是鍍(du)(du)鋅(xin)(xin)管(guan)(guan)(guan)。
