熱鍍鋅管是使(shi)熔融(rong)(rong)金屬與鐵基體(ti)反(fan)應而(er)(er)產(chan)生合金層(ceng),從而(er)(er)使(shi)基體(ti)和鍍(du)(du)(du)層(ceng)二(er)者相結合。熱(re)(re)鍍(du)(du)(du)鋅是先將鋼管進(jin)行酸(suan)洗(xi),為了去除鋼管表面的氧化(hua)(hua)(hua)鐵,酸(suan)洗(xi)后(hou),通過(guo)氯(lv)化(hua)(hua)(hua)銨或氯(lv)化(hua)(hua)(hua)鋅水溶液或氯(lv)化(hua)(hua)(hua)銨和氯(lv)化(hua)(hua)(hua)鋅混合水溶液槽中進(jin)行清洗(xi),然后(hou)送入熱(re)(re)浸鍍(du)(du)(du)槽中。熱(re)(re)鍍(du)(du)(du)鋅具(ju)有鍍(du)(du)(du)層(ceng)均勻,附著力強,使(shi)用(yong)壽命(ming)長(chang)等優點(dian)。熱(re)(re)鍍(du)(du)(du)鋅鋼管基體(ti)。鍍(du)(du)(du)鋅管與熔融(rong)(rong)的鍍(du)(du)(du)液發生復雜的物理、化(hua)(hua)(hua)學反(fan)應,形成耐(nai)腐蝕(shi)的結構緊(jin)密的鋅一(yi)(yi)鐵合金層(ceng)。合金層(ceng)與純鋅層(ceng)、鋼管基體(ti)融(rong)(rong)為一(yi)(yi)體(ti),故其耐(nai)腐蝕(shi)能(neng)力強。
鍍鋅方管廠家(jia)解析什么(me)是鍍鋅鋼管?
冷(leng)(leng)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)管就是電(dian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin),鍍(du)(du)(du)(du)(du)鋅(xin)(xin)量(liang)很少(shao),只有10-50g/m2,其(qi)本身(shen)的(de)耐(nai)腐(fu)(fu)蝕(shi)性比熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)管相(xiang)差很多。正規(gui)的(de)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)管生產廠家(jia),為了(le)保證質(zhi)量(liang),大多不采用(yong)(yong)電(dian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(冷(leng)(leng)鍍(du)(du)(du)(du)(du))。只有那些規(gui)模小(xiao)、設備陳舊的(de)小(xiao)企業采用(yong)(yong)電(dian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin),當然他們的(de)價格也相(xiang)對(dui)便宜一些。建設部已(yi)正式下文,淘(tao)汰技術落(luo)后的(de)冷(leng)(leng)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)管,不準(zhun)用(yong)(yong)冷(leng)(leng)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)管作水、煤氣管。 冷(leng)(leng)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)管鍍(du)(du)(du)(du)(du)鋅(xin)(xin)層是電(dian)鍍(du)(du)(du)(du)(du)層,鋅(xin)(xin)層與鋼(gang)(gang)管基體獨(du)立分(fen)層。鋅(xin)(xin)層較薄,鋅(xin)(xin)層簡(jian)單附著在鋼(gang)(gang)管基體上(shang),容易脫(tuo)落(luo)。故其(qi)耐(nai)腐(fu)(fu)蝕(shi)性能(neng)差。在新建住宅中,禁(jin)止使(shi)用(yong)(yong)冷(leng)(leng)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)管作為給水管。
