重慶(qing)鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)按生(sheng)產及加(jia)工(gong)方法可(ke)分為以(yi)下(xia)幾類： 熱浸(jin)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)(ban)浸(jin)入熔(rong)解的鋅(xin)(xin)(xin)槽(cao)中(zhong)(zhong)，使其(qi)表(biao)面(mian)粘附一(yi)層鋅(xin)(xin)(xin)的薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。目(mu)前主要采用連(lian)續鍍(du)鋅(xin)(xin)(xin)工(gong)藝生(sheng)產，即把成卷的鋼(gang)板(ban)(ban)(ban)(ban)(ban)連(lian)續浸(jin)在熔(rong)解有鋅(xin)(xin)(xin)的鍍(du)槽(cao)中(zhong)(zhong)制(zhi)成鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)； 合(he)(he)(he)金(jin)化鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。為克服單面(mian)未涂鋅(xin)(xin)(xin)的缺(que)點(dian)，又有一(yi)種(zhong)在另面(mian)涂以(yi)薄(bo)層鋅(xin)(xin)(xin)的鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)，即雙面(mian)差鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)；合(he)(he)(he)金(jin)、復(fu)合(he)(he)(he)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。它是(shi)用鋅(xin)(xin)(xin)和其(qi)他金(jin)屬如鉛(qian)、鋅(xin)(xin)(xin)制(zhi)成合(he)(he)(he)金(jin)乃至(zhi)復(fu)合(he)(he)(he)鍍(du)成的鋼(gang)板(ban)(ban)(ban)(ban)(ban)。這種(zhong)鋼(gang)板(ban)(ban)(ban)(ban)(ban)既具有防銹(xiu)性能(neng)，又有良好的涂裝性能(neng)。

鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)是為防止鋼(gang)(gang)(gang)板(ban)(ban)(ban)表(biao)面遭受腐蝕，延長其(qi)使用壽命，在鋼(gang)(gang)(gang)板(ban)(ban)(ban)表(biao)面涂以(yi)一(yi)層(ceng)金屬鋅(xin)(xin)，這種涂鋅(xin)(xin)的(de)(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)稱為鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)。按生(sheng)(sheng)產及加(jia)工方法(fa)可分為以(yi)下(xia)幾類：熱浸(jin)鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)浸(jin)入熔 微商貨源(yuan)解(jie)(jie)的(de)(de)鋅(xin)(xin)槽(cao)中，使其(qi)表(biao)面粘(zhan)附一(yi)層(ceng)鋅(xin)(xin)的(de)(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。目前(qian)主要(yao)采用連續(xu)鍍(du)鋅(xin)(xin)工藝生(sheng)(sheng)產，即把(ba)成卷的(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)連續(xu)浸(jin)在熔解(jie)(jie)有(you)鋅(xin)(xin)的(de)(de)鍍(du)槽(cao)中制成鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)；合(he)(he)金化(hua)鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。這種鋼(gang)(gang)(gang)板(ban)(ban)(ban)也是用熱浸(jin)法(fa)制造，但在出(chu)槽(cao)后，立即把(ba)它加(jia)熱到(dao)５００℃左(zuo)右，使其(qi)生(sheng)(sheng)成鋅(xin)(xin)和鐵(tie)的(de)(de)合(he)(he)金被膜(mo)。這種鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)具有(you)良好的(de)(de)涂料的(de)(de)密著(zhu)性和焊接性。

冷軋板批發樓承板本身有良好的延伸性，自重輕，自振周期長，較大變形下能吸收變形能，結構體系的連接多為柔性連接，圍護結構可隨主體結構發生變位，其抗震性能得到了大大提高。自重減輕也會增強其抗震性能，自重減少一半，等同于降低抗震設防烈度一度，地震作用可降低30％—40％J，從而減少了很多有關抗震的構造要求，降低了工程造價。我國面臨水土流失、環境污染等一系列影響可持續發展的問題，環保建筑的提出應運而生，環保建筑之能源利用高、環境好、在保障人們生活的基礎上消耗低，使用周期長等。湖北冷軋板樓承板建(jian)筑恰恰在這些方面(mian)能夠(gou)滿(man)足(zu)要求(qiu)，與(yu)其他建(jian)筑結(jie)構體(ti)系相比，樓承板建(jian)筑沒(mei)有(you)(you)空氣污(wu)染和噪音(yin)，也不會對森林等資源造成破壞，并且建(jian)筑材(cai)料可以回收再(zai)利用，減少了固體(ti)垃圾的出現，有(you)(you)利于人(ren)與(yu)自(zi)然的協調發展，代(dai)表著建(jian)筑行業的新水平。
