重(zhong)慶鍍(du)鋅(xin)板(ban)近二十年來鋼(gang)帶連續熱鍍(du)鋅(xin)技(ji)術、裝備以(yi)及(ji)相應的控制(zhi)(zhi)手(shou)段均有(you)巨大的發展，使鍍(du)鋅(xin)板(ban)得以(yi)滿足(zu)汽(qi)車面板(ban)和家電用(yong)板(ban)的苛刻要求，并(bing)從而(er)以(yi)其比電鍍(du)鋅(xin)合金鋼(gang)帶廉價、耐(nai)蝕性(xing)優異而(er)大有(you)取代之勢。熱鍍(du)鋅(xin)生產(chan)(chan)技(ji)術與(yu)裝備開(kai)發技(ji)術及(ji)經驗，通過(guo)技(ji)術創新、優化設計、精密制(zhi)(zhi)造以(yi)及(ji)國外(wai)技(ji)術合作，突破制(zhi)(zhi)約我國高性(xing)能汽(qi)車用(yong)熱鍍(du)鋅(xin)鋼(gang)板(ban)生產(chan)(chan)技(ji)術與(yu)裝備發展瓶(ping)頸。

鍍鋅板價格熱鍍鋅板和電鍍鋅板在鍍鋅量上有很大的差別，就像山東彩涂卷）。熱鍍鋅的鍍鋅量不可能太小，一般較小為雙面50～60g／m2，較大可達600g／m2。渝北鍍鋅板電(dian)鍍(du)(du)鋅板的(de)(de)(de)鍍(du)(du)鋅層可(ke)以很(hen)薄，較小達15g／m2，但要求(qiu)鍍(du)(du)層較厚的(de)(de)(de)話則(ze)生產(chan)線速度很(hen)慢，不適應現代化機組的(de)(de)(de)工藝特點，一(yi)般(ban)較大為lO0g／m2左右。正因為如此，電(dian)鍍(du)(du)鋅板的(de)(de)(de)生產(chan)受到很(hen)大的(de)(de)(de)限制。工一(yi)般(ban)電(dian)鍍(du)(du)鋅比較多，適用(yong)(yong)于(yu)小部(bu)(bu)件(jian)(jian)；熱鍍(du)(du)鋅一(yi)般(ban)用(yong)(yong)于(yu)電(dian)力設(she)備和構件(jian)(jian)，適用(yong)(yong)于(yu)大的(de)(de)(de)部(bu)(bu)件(jian)(jian)和設(she)備。當(dang)然他們(men)的(de)(de)(de)價(jia)格也相對便宜(yi)一(yi)些。建設(she)部(bu)(bu)已正式下(xia)文(wen)，淘汰技術(shu)落后的(de)(de)(de)冷鍍(du)(du)鋅管，不準用(yong)(yong)冷鍍(du)(du)鋅管作水(shui)、煤氣管。

用(yong)(yong)電鍍(du)(du)法(fa)制造這種(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)具有(you)良好的(de)加(jia)工(gong)性(xing)。但鍍(du)(du)層較薄，耐腐蝕(shi)性(xing)不如熱浸法(fa)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)；單面(mian)(mian)鍍(du)(du)和雙(shuang)(shuang)面(mian)(mian)差鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。單面(mian)(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)，即(ji)只(zhi)在一(yi)面(mian)(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)的(de)產品。在焊接、涂裝、防(fang)銹(xiu)處理、加(jia)工(gong)等(deng)方面(mian)(mian)，具有(you)比雙(shuang)(shuang)面(mian)(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)好的(de)適應性(xing)。為克(ke)服單面(mian)(mian)未(wei)涂鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)的(de)缺點，又(you)有(you)一(yi)種(zhong)在另(ling)面(mian)(mian)涂以薄層鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)的(de)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)，即(ji)雙(shuang)(shuang)面(mian)(mian)差鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)；合(he)金(jin)(jin)、復(fu)合(he)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。它(ta)是(shi)用(yong)(yong)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)和其(qi)他金(jin)(jin)屬如鉛(qian)、鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)制成合(he)金(jin)(jin)乃至復(fu)合(he)鍍(du)(du)成的(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。這種(zhong)鋼(gang)(gang)(gang)(gang)板(ban)(ban)既具有(you)防(fang)銹(xiu)性(xing)能，又(you)有(you)良好的(de)涂裝性(xing)能。 除上述五種(zhong)外，還有(you)彩色鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)、印(yin)花涂裝鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)、聚氯(lv)乙烯(xi)疊層鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)等(deng)。但目前常用(yong)(yong)的(de)仍為熱浸鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)。 鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)按用(yong)(yong)途又(you)可(ke)分為一(yi)般用(yong)(yong)、屋頂用(yong)(yong)、建筑外側板(ban)(ban)用(yong)(yong)、結構用(yong)(yong)、瓦壟板(ban)(ban)用(yong)(yong)、拉伸(shen)用(yong)(yong)和深(shen)沖用(yong)(yong)等(deng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)。

重慶樓承板(ban)(ban)(ban)的(de)(de)(de)鍍(du)(du)(du)鋅(xin)(xin)量沒(mei)有一個具(ju)體的(de)(de)(de)標準，制作壓型(xing)鋼(gang)(gang)(gang)板(ban)(ban)(ban)的(de)(de)(de)冷(leng)軋鋼(gang)(gang)(gang)卷須(xu)連續熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)（或鍍(du)(du)(du)鋁鋅(xin)(xin)），鍍(du)(du)(du)（鋁）鋅(xin)(xin)量視設計(ji)要求而定。樓承板(ban)(ban)(ban)用壓型(xing)鋼(gang)(gang)(gang)板(ban)(ban)(ban)宜選擇熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。不允許(xu)使用電鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)，電鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)僅(jin)在(zai)基材(cai)表(biao)面(mian)形成保(bao)護層(ceng)，防(fang)腐(fu)(fu)能力有限。目(mu)前(qian)市場上有鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)（鍍(du)(du)(du)層(ceng)含鋁5%或55%），在(zai)酸性環境下的(de)(de)(de)防(fang)腐(fu)(fu)效果(guo)由于(yu)熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)，但在(zai)混凝(ning)土的(de)(de)(de)堿性條件下，鍍(du)(du)(du)鋁鋅(xin)(xin)的(de)(de)(de)防(fang)腐(fu)(fu)蝕性能低于(yu)熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)，且鋁會和混凝(ning)土發生反應(ying)，并(bing)降(jiang)低混凝(ning)土與鋼(gang)(gang)(gang)板(ban)(ban)(ban)的(de)(de)(de)粘結(jie)性能。因此參考國外(wai)規范，及國內(nei)外(wai)工程，行家壓型(xing)鋼(gang)(gang)(gang)板(ban)(ban)(ban)不建議(yi)使用鍍(du)(du)(du)鋁鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。
