商洛鍍鋅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。鍍鋅卷價格樓承板(ban)用(yong)壓(ya)型(xing)鋼(gang)(gang)(gang)板(ban)宜(yi)選擇熱(re)浸(jin)鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)。不(bu)允(yun)許(xu)使用(yong)電鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)，電鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)僅在(zai)基(ji)材表面形成保護層，防腐能力有限(xian)。目前市(shi)場上有鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)（鍍(du)(du)層含(han)鋁5%或55%），在(zai)酸性(xing)環境下的(de)防腐效果由于熱(re)浸(jin)鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)，但在(zai)混凝土的(de)堿性(xing)條件(jian)下，鍍(du)(du)鋁鋅(xin)(xin)的(de)防腐蝕性(xing)能低于熱(re)浸(jin)鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)，且鋁會和混凝土發生(sheng)反(fan)應(ying)，并降低混凝土與鋼(gang)(gang)(gang)板(ban)的(de)粘結性(xing)能。因此參考國外規范，及(ji)國內(nei)外工程，行(xing)家壓(ya)型(xing)鋼(gang)(gang)(gang)板(ban)不(bu)建議使用(yong)鍍(du)(du)鋁鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)。

用(yong)電鍍(du)(du)法制造這(zhe)種鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)具有(you)良好(hao)的加工(gong)性(xing)。但(dan)(dan)鍍(du)(du)層較薄，耐腐蝕性(xing)不如熱(re)浸(jin)法鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)；單(dan)面(mian)(mian)(mian)鍍(du)(du)和(he)雙(shuang)面(mian)(mian)(mian)差(cha)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。單(dan)面(mian)(mian)(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)，即只在一面(mian)(mian)(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)的產品。在焊(han)接、涂裝(zhuang)、防(fang)(fang)銹(xiu)處理、加工(gong)等方面(mian)(mian)(mian)，具有(you)比雙(shuang)面(mian)(mian)(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)好(hao)的適應性(xing)。為(wei)克服單(dan)面(mian)(mian)(mian)未涂鋅(xin)(xin)(xin)(xin)的缺點，又有(you)一種在另面(mian)(mian)(mian)涂以薄層鋅(xin)(xin)(xin)(xin)的鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)，即雙(shuang)面(mian)(mian)(mian)差(cha)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)；合金(jin)(jin)、復合鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。它是用(yong)鋅(xin)(xin)(xin)(xin)和(he)其他金(jin)(jin)屬如鉛(qian)、鋅(xin)(xin)(xin)(xin)制成合金(jin)(jin)乃至復合鍍(du)(du)成的鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)既具有(you)防(fang)(fang)銹(xiu)性(xing)能，又有(you)良好(hao)的涂裝(zhuang)性(xing)能。 除上(shang)述(shu)五種外，還有(you)彩(cai)色鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)、印花涂裝(zhuang)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)、聚氯乙烯疊層鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)等。但(dan)(dan)目前常用(yong)的仍為(wei)熱(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)。 鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)按用(yong)途(tu)又可分(fen)為(wei)一般用(yong)、屋頂(ding)用(yong)、建筑外側板(ban)(ban)(ban)(ban)(ban)(ban)用(yong)、結構用(yong)、瓦壟(long)板(ban)(ban)(ban)(ban)(ban)(ban)用(yong)、拉伸(shen)用(yong)和(he)深(shen)沖用(yong)等鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。

鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板的(de)(de)表面(mian)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)主要采(cai)用(yong)的(de)(de)方法是熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)。熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)是由(you)較古老的(de)(de)熱(re)鍍(du)(du)(du)(du)(du)(du)方法發展(zhan)(zhan)而(er)來的(de)(de)，自(zi)從1836年法國把熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)應用(yong)于工(gong)業(ye)以來，已(yi)經有(you)一百七十年的(de)(de)歷史了。然而(er)，熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)工(gong)業(ye)是近(jin)(jin)三(san)十年來伴隨(sui)冷(leng)軋帶鋼(gang)的(de)(de)飛速發展(zhan)(zhan)而(er)得到(dao)了大規模(mo)發展(zhan)(zhan)。鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)(ye)有(you)氰(qing)(qing)(qing)化物(wu)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)和無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)兩類。氰(qing)(qing)(qing)化物(wu)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)中分微(wei)氰(qing)(qing)(qing)、低(di)氰(qing)(qing)(qing)、中氰(qing)(qing)(qing)、和高(gao)氰(qing)(qing)(qing)幾類。無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)有(you)堿(jian)性(xing)鋅(xin)(xin)(xin)酸鹽(yan)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)、銨鹽(yan)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)、硫(liu)酸鹽(yan)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)及無氨(an)氯化物(wu)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)等。氰(qing)(qing)(qing)化鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)(ye)均(jun)鍍(du)(du)(du)(du)(du)(du)能力好，得到(dao)的(de)(de)鍍(du)(du)(du)(du)(du)(du)層光(guang)滑細致，在生產中被長期(qi)采(cai)用(yong)。但由(you)于氰(qing)(qing)(qing)化物(wu)劇毒，對環(huan)境污(wu)染嚴重，近(jin)(jin)年來已(yi)趨(qu)向于采(cai)用(yong)低(di)氰(qing)(qing)(qing)、微(wei)氰(qing)(qing)(qing)、無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)(ye)。

重慶鍍(du)鋅(xin)(xin)板(ban)按生產(chan)(chan)及加工方(fang)法可分為以下幾類： 熱浸(jin)鍍(du)鋅(xin)(xin)鋼(gang)板(ban)。將薄(bo)鋼(gang)板(ban)浸(jin)入熔(rong)解的(de)鋅(xin)(xin)槽中(zhong)，使(shi)其表面(mian)(mian)粘附(fu)一(yi)層(ceng)鋅(xin)(xin)的(de)薄(bo)鋼(gang)板(ban)。目前(qian)主要采用連(lian)續鍍(du)鋅(xin)(xin)工藝生產(chan)(chan)，即把成(cheng)卷的(de)鋼(gang)板(ban)連(lian)續浸(jin)在(zai)熔(rong)解有(you)鋅(xin)(xin)的(de)鍍(du)槽中(zhong)制(zhi)成(cheng)鍍(du)鋅(xin)(xin)鋼(gang)板(ban)； 合(he)金(jin)化鍍(du)鋅(xin)(xin)鋼(gang)板(ban)。為克(ke)服單面(mian)(mian)未(wei)涂鋅(xin)(xin)的(de)缺點，又有(you)一(yi)種(zhong)在(zai)另(ling)面(mian)(mian)涂以薄(bo)層(ceng)鋅(xin)(xin)的(de)鍍(du)鋅(xin)(xin)板(ban)，即雙面(mian)(mian)差(cha)鍍(du)鋅(xin)(xin)板(ban)；合(he)金(jin)、復(fu)合(he)鍍(du)鋅(xin)(xin)鋼(gang)板(ban)。它(ta)是(shi)用鋅(xin)(xin)和其他金(jin)屬如鉛、鋅(xin)(xin)制(zhi)成(cheng)合(he)金(jin)乃至復(fu)合(he)鍍(du)成(cheng)的(de)鋼(gang)板(ban)。這種(zhong)鋼(gang)板(ban)既具有(you)防銹性(xing)能，又有(you)良(liang)好(hao)的(de)涂裝性(xing)能。

樓(lou)承(cheng)板在(zai)建筑(zhu)(zhu)當中(zhong)已經(jing)被廣泛的(de)(de)(de)使(shi)用(yong)，對于此種設備(bei)的(de)(de)(de)標準化和工廠化的(de)(de)(de)程度已經(jing)是(shi)(shi)越來越高了(le)，那(nei)(nei)么(me)它(ta)們(men)(men)現(xian)(xian)在(zai)已經(jing)發(fa)展(zhan)成為了(le)產業(ye)(ye)化的(de)(de)(de)趨(qu)勢，那(nei)(nei)么(me)在(zai)未來對于桁架樓(lou)承(cheng)板來說，應該有(you)好的(de)(de)(de)市場發(fa)展(zhan)前景，現(xian)(xian)在(zai)我(wo)們(men)(men)就要來說一(yi)說鋼筋桁架樓(lou)承(cheng)板在(zai)使(shi)用(yong)過程當中(zhong)如何進行(xing)防腐的(de)(de)(de)操(cao)作。如今對于我(wo)們(men)(men)國(guo)(guo)家(jia)的(de)(de)(de)建筑(zhu)(zhu)鋼結構來說，它(ta)們(men)(men)的(de)(de)(de)發(fa)展(zhan)趨(qu)勢是(shi)(shi)特別好的(de)(de)(de)，它(ta)們(men)(men)也大大的(de)(de)(de)推動(dong)了(le)我(wo)們(men)(men)國(guo)(guo)家(jia)的(de)(de)(de)冶金行(xing)業(ye)(ye)的(de)(de)(de)發(fa)展(zhan)，現(xian)(xian)在(zai)對于建筑(zhu)(zhu)行(xing)業(ye)(ye)和冶金行(xing)業(ye)(ye)已經(jing)緊緊的(de)(de)(de)聯系在(zai)一(yi)起了(le)。對于未來我(wo)們(men)(men)的(de)(de)(de)鋼筋桁架樓(lou)承(cheng)板將會處于一(yi)個新的(de)(de)(de)發(fa)展(zhan)時期。
