南充彩涂卷重慶樓承板的鍍鋅量沒有一個具體的標準，制作壓型鋼板的冷軋鋼卷須連續熱浸鍍鋅（或鍍鋁鋅），鍍（鋁）鋅量視設計要求而定。彩涂卷廠家樓承板(ban)(ban)(ban)用(yong)(yong)壓(ya)型(xing)鋼(gang)(gang)板(ban)(ban)(ban)宜(yi)選擇(ze)熱(re)浸(jin)鍍(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)。不允(yun)許使(shi)用(yong)(yong)電(dian)(dian)鍍(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)，電(dian)(dian)鍍(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)僅在(zai)基材表面形成保(bao)護層，防(fang)腐能(neng)力有限。目前市(shi)場上有鍍(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)（鍍(du)層含(han)鋁(lv)(lv)5%或55%），在(zai)酸性環境下(xia)的防(fang)腐效果由于熱(re)浸(jin)鍍(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)，但在(zai)混(hun)凝土(tu)的堿性條(tiao)件(jian)下(xia)，鍍(du)鋁(lv)(lv)鋅(xin)(xin)的防(fang)腐蝕性能(neng)低于熱(re)浸(jin)鍍(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)，且(qie)鋁(lv)(lv)會和混(hun)凝土(tu)發(fa)生反應，并降低混(hun)凝土(tu)與鋼(gang)(gang)板(ban)(ban)(ban)的粘(zhan)結(jie)性能(neng)。因此參考國外規范，及國內外工程(cheng)，行家(jia)壓(ya)型(xing)鋼(gang)(gang)板(ban)(ban)(ban)不建議(yi)使(shi)用(yong)(yong)鍍(du)鋁(lv)(lv)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)。

鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)是(shi)為防止鋼(gang)(gang)(gang)板(ban)(ban)(ban)表(biao)(biao)面(mian)遭受腐蝕(shi)，延長其(qi)使(shi)(shi)用(yong)(yong)(yong)壽命，在鋼(gang)(gang)(gang)板(ban)(ban)(ban)表(biao)(biao)面(mian)涂(tu)以(yi)一(yi)層金屬鋅(xin)(xin)(xin)(xin)(xin)，這(zhe)種(zhong)涂(tu)鋅(xin)(xin)(xin)(xin)(xin)的(de)薄(bo)(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)稱為鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)。鋼(gang)(gang)(gang)板(ban)(ban)(ban)也是(shi)用(yong)(yong)(yong)熱(re)浸(jin)(jin)法制(zhi)(zhi)造，但在出(chu)槽后，立即把它(ta)加熱(re)到500℃左右，使(shi)(shi)其(qi)生(sheng)成(cheng)鋅(xin)(xin)(xin)(xin)(xin)和鐵的(de)合金被(bei)膜。這(zhe)種(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)卷具有良好的(de)涂(tu)料(liao)的(de)密著性(xing)(xing)和焊接(jie)性(xing)(xing)。合金化(hua)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。這(zhe)種(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)也是(shi)用(yong)(yong)(yong)熱(re)浸(jin)(jin)法制(zhi)(zhi)造，但在出(chu)槽后，立即把它(ta)加熱(re)到500℃左右，使(shi)(shi)其(qi)生(sheng)成(cheng)鋅(xin)(xin)(xin)(xin)(xin)和鐵的(de)合金被(bei)膜。這(zhe)種(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)具有良好的(de)涂(tu)料(liao)的(de)密著性(xing)(xing)和焊接(jie)性(xing)(xing)。熱(re)浸(jin)(jin)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。將薄(bo)(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)浸(jin)(jin)入熔解的(de)鋅(xin)(xin)(xin)(xin)(xin)槽中(zhong)，使(shi)(shi)其(qi)表(biao)(biao)面(mian)粘附一(yi)層鋅(xin)(xin)(xin)(xin)(xin)的(de)薄(bo)(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。目(mu)前(qian)主要采用(yong)(yong)(yong)連續鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)工藝生(sheng)產，即把成(cheng)卷的(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)連續浸(jin)(jin)在熔解有鋅(xin)(xin)(xin)(xin)(xin)的(de)鍍(du)(du)槽中(zhong)制(zhi)(zhi)成(cheng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。合金、復合鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。它(ta)是(shi)用(yong)(yong)(yong)鋅(xin)(xin)(xin)(xin)(xin)和其(qi)他金屬如鉛、鋅(xin)(xin)(xin)(xin)(xin)制(zhi)(zhi)成(cheng)合金乃至復合鍍(du)(du)成(cheng)的(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。這(zhe)種(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)既具有防銹性(xing)(xing)能，又有良好的(de)涂(tu)裝性(xing)(xing)能。
