重慶鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)按生產及加工方法可(ke)分為(wei)以下幾類： 熱(re)浸(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。將薄(bo)鋼(gang)板(ban)(ban)(ban)浸(jin)入熔解(jie)的(de)(de)(de)鋅(xin)(xin)(xin)槽中，使其表面(mian)粘附一(yi)層鋅(xin)(xin)(xin)的(de)(de)(de)薄(bo)鋼(gang)板(ban)(ban)(ban)。目前主要采用連續鍍(du)(du)(du)鋅(xin)(xin)(xin)工藝生產，即(ji)把成卷的(de)(de)(de)鋼(gang)板(ban)(ban)(ban)連續浸(jin)在熔解(jie)有鋅(xin)(xin)(xin)的(de)(de)(de)鍍(du)(du)(du)槽中制成鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)； 合金(jin)化鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。為(wei)克服(fu)單面(mian)未涂(tu)鋅(xin)(xin)(xin)的(de)(de)(de)缺點，又(you)有一(yi)種在另面(mian)涂(tu)以薄(bo)層鋅(xin)(xin)(xin)的(de)(de)(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)，即(ji)雙面(mian)差鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)；合金(jin)、復合鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。它是(shi)用鋅(xin)(xin)(xin)和其他(ta)金(jin)屬如鉛、鋅(xin)(xin)(xin)制成合金(jin)乃(nai)至復合鍍(du)(du)(du)成的(de)(de)(de)鋼(gang)板(ban)(ban)(ban)。這種鋼(gang)板(ban)(ban)(ban)既具(ju)有防銹性(xing)能，又(you)有良好的(de)(de)(de)涂(tu)裝性(xing)能。

由于我國(guo)鋅(xin)資源比較豐富，鍍(du)鋅(xin)又(you)是一種價廉、能防銹(xiu)，又(you)能裝(zhuang)飾的高性價比鍍(du)種，因而在汽車(che)、機(ji)械、電(dian)(dian)子、船舶、儀表、輕工(gong)等(deng)工(gong)業(ye)(ye)部(bu)門(men)得(de)到廣泛的應用(yong)。如機(ji)械零件、低壓電(dian)(dian)器(qi)、高壓開關、緊固連接件、鋼(gang)鐵結構(gou)(gou)件、建(jian)筑(zhu)五金、農業(ye)(ye)機(ji)械、輕工(gong)產(chan)品等(deng)都(dou)離不(bu)開鍍(du)鋅(xin)鈍化制品。鍍(du)鋅(xin)板卷因此(ci)可分(fen)為熱軋鍍(du)鋅(xin)板卷和冷軋熱鍍(du)鋅(xin)板卷，它們(men)主(zhu)要用(yong)于建(jian)筑(zhu)、家(jia)電(dian)(dian)、汽車(che)、容(rong)器(qi)、交(jiao)通(tong)及家(jia)業(ye)(ye)等(deng)領域(yu)。特別是鋼(gang)結構(gou)(gou)建(jian)筑(zhu)、汽車(che)制造(zao)、鋼(gang)板倉制造(zao)等(deng)行業(ye)(ye)。 重慶(qing)鍍(du)鋅(xin)卷特點主(zhu)要為：耐腐蝕強、表面質量好、得(de)利于深加工(gong)、經濟(ji)實用(yong)等(deng)。

重慶樓承板(ban)(ban)(ban)(ban)(ban)的鍍(du)(du)(du)鋅(xin)(xin)量沒有(you)(you)一個具體的標準(zhun)，制作壓型鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的冷軋鋼(gang)(gang)(gang)(gang)卷須(xu)連續熱(re)(re)浸鍍(du)(du)(du)鋅(xin)(xin)（或鍍(du)(du)(du)鋁(lv)(lv)鋅(xin)(xin)），鍍(du)(du)(du)（鋁(lv)(lv)）鋅(xin)(xin)量視設計要求而定。樓承板(ban)(ban)(ban)(ban)(ban)用(yong)壓型鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)宜(yi)選擇(ze)熱(re)(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。不允許(xu)使用(yong)電鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，電鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)僅在基材表面形成保(bao)護層(ceng)，防(fang)(fang)腐能(neng)力有(you)(you)限。目前(qian)市場(chang)上有(you)(you)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)（鍍(du)(du)(du)層(ceng)含鋁(lv)(lv)5%或55%），在酸性環境(jing)下的防(fang)(fang)腐效果由于(yu)熱(re)(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，但在混(hun)(hun)凝土的堿性條件下，鍍(du)(du)(du)鋁(lv)(lv)鋅(xin)(xin)的防(fang)(fang)腐蝕性能(neng)低于(yu)熱(re)(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，且鋁(lv)(lv)會和混(hun)(hun)凝土發生(sheng)反應，并降(jiang)低混(hun)(hun)凝土與鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的粘結性能(neng)。因此(ci)參(can)考(kao)國外規范(fan)，及(ji)國內外工程，行家壓型鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)不建(jian)議使用(yong)鍍(du)(du)(du)鋁(lv)(lv)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。

C型鋼廠家樓承板在建筑當中已經被廣泛的使用，對于此種設備的標準化和工廠化的程度已經是越來越高了，那么它們現在已經發展成為了產業化的趨勢，那么在未來對于桁架樓承板來說，應該有好的市場發展前景，現在我們就要來說一說鋼筋桁架樓承板在使用過程當中如何進行防腐的操作。如今對于我們國家的建筑鋼結構來說，它們的發展趨勢是特別好的，它們也大大的推動了我們國家的冶金行業的發展，現在對于建筑行業和冶金行業已經緊緊的聯系在一起了。宜賓C型鋼對于未(wei)來我(wo)們的(de)鋼筋桁架(jia)樓承板(ban)將(jiang)會處于一個新(xin)的(de)發(fa)展時期。
