熱鍍鋅管是使熔融金(jin)(jin)屬(shu)與(yu)(yu)鐵基(ji)體反應而產生合(he)金(jin)(jin)層(ceng)，從而使基(ji)體和(he)鍍(du)(du)(du)層(ceng)二者相結合(he)。熱鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)是先將鋼管(guan)進行酸洗，為了(le)去除鋼管(guan)表面的(de)氧(yang)化(hua)(hua)鐵，酸洗后，通過(guo)氯化(hua)(hua)銨或氯化(hua)(hua)鋅(xin)(xin)(xin)(xin)水(shui)溶液或氯化(hua)(hua)銨和(he)氯化(hua)(hua)鋅(xin)(xin)(xin)(xin)混合(he)水(shui)溶液槽(cao)(cao)中(zhong)進行清(qing)洗，然后送(song)入(ru)熱浸鍍(du)(du)(du)槽(cao)(cao)中(zhong)。熱鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)具(ju)有鍍(du)(du)(du)層(ceng)均勻(yun)，附著力強，使用壽命(ming)長等優點。熱鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼管(guan)基(ji)體。鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)管(guan)與(yu)(yu)熔融的(de)鍍(du)(du)(du)液發生復雜的(de)物理、化(hua)(hua)學反應，形(xing)成耐(nai)腐蝕的(de)結構緊密(mi)的(de)鋅(xin)(xin)(xin)(xin)一鐵合(he)金(jin)(jin)層(ceng)。合(he)金(jin)(jin)層(ceng)與(yu)(yu)純鋅(xin)(xin)(xin)(xin)層(ceng)、鋼管(guan)基(ji)體融為一體，故其耐(nai)腐蝕能力強。

鍍鋅方管廠家解析什么是鍍鋅鋼(gang)管(guan)？

冷(leng)鍍(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)(guan)就是電(dian)(dian)鍍(du)(du)鋅(xin)(xin)(xin)，鍍(du)(du)鋅(xin)(xin)(xin)量很(hen)少，只有10－50g/m2，其(qi)本(ben)身(shen)的(de)耐腐蝕性(xing)(xing)比熱鍍(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)(guan)相差很(hen)多。正規(gui)的(de)鍍(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)(guan)生產廠家，為了保(bao)證(zheng)質量，大多不采(cai)用(yong)電(dian)(dian)鍍(du)(du)鋅(xin)(xin)(xin)（冷(leng)鍍(du)(du)）。只有那些規(gui)模小(xiao)、設(she)備陳(chen)舊(jiu)的(de)小(xiao)企業采(cai)用(yong)電(dian)(dian)鍍(du)(du)鋅(xin)(xin)(xin)，當然他們的(de)價格(ge)也(ye)相對(dui)便宜(yi)一(yi)些。建(jian)設(she)部已(yi)正式下文，淘汰技(ji)術落后的(de)冷(leng)鍍(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)(guan)，不準用(yong)冷(leng)鍍(du)(du)鋅(xin)(xin)(xin)管(guan)(guan)(guan)作水、煤氣管(guan)(guan)(guan)。 冷(leng)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)管(guan)(guan)(guan)鍍(du)(du)鋅(xin)(xin)(xin)層(ceng)(ceng)(ceng)是電(dian)(dian)鍍(du)(du)層(ceng)(ceng)(ceng)，鋅(xin)(xin)(xin)層(ceng)(ceng)(ceng)與鋼(gang)(gang)管(guan)(guan)(guan)基體獨立分(fen)層(ceng)(ceng)(ceng)。鋅(xin)(xin)(xin)層(ceng)(ceng)(ceng)較薄，鋅(xin)(xin)(xin)層(ceng)(ceng)(ceng)簡單附著在(zai)(zai)鋼(gang)(gang)管(guan)(guan)(guan)基體上，容(rong)易(yi)脫落。故其(qi)耐腐蝕性(xing)(xing)能差。在(zai)(zai)新建(jian)住宅中，禁(jin)止使用(yong)冷(leng)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)管(guan)(guan)(guan)作為給(gei)水管(guan)(guan)(guan)。
