重慶樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)的鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)量沒有一個具體的標準(zhun)，制作壓型(xing)鋼(gang)板(ban)(ban)(ban)(ban)(ban)的冷軋鋼(gang)卷須連續熱(re)浸鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)（或鍍(du)(du)(du)(du)鋁(lv)(lv)鋅(xin)(xin)(xin)(xin)），鍍(du)(du)(du)(du)（鋁(lv)(lv)）鋅(xin)(xin)(xin)(xin)量視設計要求而(er)定(ding)。樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)用壓型(xing)鋼(gang)板(ban)(ban)(ban)(ban)(ban)宜選(xuan)擇熱(re)浸鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。不(bu)允(yun)許使用電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)，電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)僅在(zai)基材(cai)表面形成保(bao)護(hu)層，防(fang)腐能力(li)有限。目前市場(chang)上有鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)（鍍(du)(du)(du)(du)層含鋁(lv)(lv)5%或55%），在(zai)酸性(xing)環境下(xia)(xia)的防(fang)腐效(xiao)果由于熱(re)浸鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)，但在(zai)混凝土(tu)(tu)的堿性(xing)條件下(xia)(xia)，鍍(du)(du)(du)(du)鋁(lv)(lv)鋅(xin)(xin)(xin)(xin)的防(fang)腐蝕性(xing)能低于熱(re)浸鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)，且鋁(lv)(lv)會和混凝土(tu)(tu)發生反(fan)應，并降低混凝土(tu)(tu)與鋼(gang)板(ban)(ban)(ban)(ban)(ban)的粘結性(xing)能。因此(ci)參考國(guo)(guo)外規范，及(ji)國(guo)(guo)內(nei)外工程，行(xing)家壓型(xing)鋼(gang)板(ban)(ban)(ban)(ban)(ban)不(bu)建(jian)議使用鍍(du)(du)(du)(du)鋁(lv)(lv)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。

熱(re)鍍(du)(du)鋅(xin)(xin)(xin)板和電(dian)鍍(du)(du)鋅(xin)(xin)(xin)板在鍍(du)(du)鋅(xin)(xin)(xin)量上有很(hen)(hen)大(da)的差別，就像山東彩涂卷）。熱(re)鍍(du)(du)鋅(xin)(xin)(xin)的鍍(du)(du)鋅(xin)(xin)(xin)量不(bu)(bu)可能太小(xiao)，一(yi)(yi)(yi)般較(jiao)(jiao)小(xiao)為雙面50～60g／m2，較(jiao)(jiao)大(da)可達600g／m2。電(dian)鍍(du)(du)鋅(xin)(xin)(xin)板的鍍(du)(du)鋅(xin)(xin)(xin)層可以很(hen)(hen)薄(bo)，較(jiao)(jiao)小(xiao)達15g／m2，但要求鍍(du)(du)層較(jiao)(jiao)厚的話則生產線速度很(hen)(hen)慢，不(bu)(bu)適(shi)應現代化(hua)機組的工藝特點，一(yi)(yi)(yi)般較(jiao)(jiao)大(da)為lO0g／m2左右。正因為如(ru)此，電(dian)鍍(du)(du)鋅(xin)(xin)(xin)板的生產受到(dao)很(hen)(hen)大(da)的限(xian)制(zhi)。工一(yi)(yi)(yi)般電(dian)鍍(du)(du)鋅(xin)(xin)(xin)比較(jiao)(jiao)多，適(shi)用于(yu)小(xiao)部(bu)件；熱(re)鍍(du)(du)鋅(xin)(xin)(xin)一(yi)(yi)(yi)般用于(yu)電(dian)力設(she)備(bei)和構件，適(shi)用于(yu)大(da)的部(bu)件和設(she)備(bei)。當然(ran)他(ta)們的價格(ge)也相(xiang)對便宜一(yi)(yi)(yi)些。建設(she)部(bu)已(yi)正式(shi)下文，淘汰(tai)技術(shu)落后的冷鍍(du)(du)鋅(xin)(xin)(xin)管(guan)，不(bu)(bu)準用冷鍍(du)(du)鋅(xin)(xin)(xin)管(guan)作(zuo)水、煤(mei)氣管(guan)。

攀鋼彩涂卷廠家樓承板能夠滿足快速施工的需求，可以在短時間內搭建起牢固的作業平臺，而且還能把多個樓承板層鋪設壓型鋼板，分層澆筑混凝土板的流水施工作業。可以作為混凝土樓板的受拉鋼筋，可以使樓板的剛度增強，而且使得鋼筋和混凝土的用量明顯減少。彩涂卷廠家壓型(xing)板表面(mian)壓紋(wen)使(shi)樓(lou)承板與混(hun)凝土之間產生大的(de)(de)結合(he)力，使(shi)二者形(xing)成(cheng)整(zheng)體，再配(pei)合(he)上加勁肋，使(shi)得(de)有高強(qiang)承載力。還可以作為(wei)性模板，懸(xuan)挑的(de)(de)長度可根據樓(lou)承板的(de)(de)截面(mian)特性來定(ding)(ding)。為(wei)了防(fang)止懸(xuan)挑板的(de)(de)開裂，需在支座處依結構(gou)工程師的(de)(de)設計配(pei)上負(fu)筋。而且(qie)都是經(jing)過固定(ding)(ding)滅火(huo)系(xi)統(tong)及耐火(huo)構(gou)件質量檢(jian)測中心的(de)(de)耐火(huo)檢(jian)測，具有防(fang)火(huo)的(de)(de)特性。

鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)是為防止鋼(gang)(gang)(gang)板(ban)(ban)表面(mian)(mian)遭受腐蝕，延(yan)長其使(shi)用(yong)壽命，在鋼(gang)(gang)(gang)板(ban)(ban)表面(mian)(mian)涂以一(yi)層(ceng)金屬鋅(xin)(xin)，這(zhe)種涂鋅(xin)(xin)的薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)稱為鍍(du)(du)鋅(xin)(xin)板(ban)(ban)。按(an)生(sheng)產及加工(gong)(gong)方法(fa)可分為以下幾類：熱浸鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)。將薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)浸入熔 微商貨源(yuan)解的鋅(xin)(xin)槽中(zhong)，使(shi)其表面(mian)(mian)粘附一(yi)層(ceng)鋅(xin)(xin)的薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)。目前主要采用(yong)連(lian)續(xu)鍍(du)(du)鋅(xin)(xin)工(gong)(gong)藝生(sheng)產，即把成(cheng)(cheng)卷的鋼(gang)(gang)(gang)板(ban)(ban)連(lian)續(xu)浸在熔解有鋅(xin)(xin)的鍍(du)(du)槽中(zhong)制成(cheng)(cheng)鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)；合(he)金化鍍(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)。這(zhe)種鋼(gang)(gang)(gang)板(ban)(ban)也是用(yong)熱浸法(fa)制造，但(dan)在出槽后，立即把它加熱到(dao)５００℃左(zuo)右，使(shi)其生(sheng)成(cheng)(cheng)鋅(xin)(xin)和(he)鐵的合(he)金被(bei)膜。這(zhe)種鍍(du)(du)鋅(xin)(xin)板(ban)(ban)具有良好的涂料的密(mi)著性(xing)(xing)和(he)焊接(jie)性(xing)(xing)。
