鍍(du)(du)(du)鋅(xin)(xin)卷分熱鍍(du)(du)(du)鋅(xin)(xin)和電(dian)鍍(du)(du)(du)鋅(xin)(xin)兩種(zhong)(zhong)，熱鍍(du)(du)(du)鋅(xin)(xin)鍍(du)(du)(du)鋅(xin)(xin)層厚，具有(you)(you)鍍(du)(du)(du)層均勻，附著(zhu)力強，使用壽命(ming)長等優點。電(dian)鍍(du)(du)(du)鋅(xin)(xin)成本低，表面不是(shi)很(hen)(hen)光滑，其本身的(de)(de)(de)耐腐蝕(shi)性(xing)比熱鍍(du)(du)(du)鋅(xin)(xin)管相差很(hen)(hen)多。提(ti)起鍍(du)(du)(du)鋅(xin)(xin)管，可能沒接觸過建材的(de)(de)(de)朋友(you)并不了解。從1935年建立(li)一條連續涂(tu)(tu)層鋼板線開始，彩(cai)涂(tu)(tu)板得到了廣泛應用，目前(qian)彩(cai)涂(tu)(tu)板的(de)(de)(de)品種(zhong)(zhong)繁多，大約(yue)超過600種(zhong)(zhong)，彩(cai)涂(tu)(tu)板兼有(you)(you)機(ji)聚合物(wu)與鋼板兩者(zhe)的(de)(de)(de)優點，既有(you)(you)有(you)(you)機(ji)聚合物(wu)的(de)(de)(de)良好著(zhu)色性(xing)、成型性(xing)、耐蝕(shi)性(xing)、裝飾性(xing)、又(you)有(you)(you)鋼板的(de)(de)(de)高強度和易加工性(xing)，能很(hen)(hen)容易地進行沖(chong)(chong)壓裁剪、彎曲、深(shen)沖(chong)(chong)等加工。

重慶(qing)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)按生(sheng)產(chan)及加工(gong)(gong)方(fang)法可分為(wei)以下幾類： 熱浸鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)。將薄鋼(gang)(gang)板(ban)(ban)(ban)浸入熔解(jie)的(de)(de)鋅(xin)(xin)(xin)(xin)槽(cao)中(zhong)，使其(qi)表面粘(zhan)附一層鋅(xin)(xin)(xin)(xin)的(de)(de)薄鋼(gang)(gang)板(ban)(ban)(ban)。目前主要采用連續鍍(du)(du)鋅(xin)(xin)(xin)(xin)工(gong)(gong)藝(yi)生(sheng)產(chan)，即(ji)把成(cheng)卷的(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)連續浸在熔解(jie)有(you)鋅(xin)(xin)(xin)(xin)的(de)(de)鍍(du)(du)槽(cao)中(zhong)制成(cheng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)； 合(he)(he)金(jin)化鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)。為(wei)克服(fu)單面未(wei)涂鋅(xin)(xin)(xin)(xin)的(de)(de)缺點，又有(you)一種(zhong)在另面涂以薄層鋅(xin)(xin)(xin)(xin)的(de)(de)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)，即(ji)雙面差鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)；合(he)(he)金(jin)、復合(he)(he)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)。它是用鋅(xin)(xin)(xin)(xin)和其(qi)他(ta)金(jin)屬如鉛、鋅(xin)(xin)(xin)(xin)制成(cheng)合(he)(he)金(jin)乃至復合(he)(he)鍍(du)(du)成(cheng)的(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)。這種(zhong)鋼(gang)(gang)板(ban)(ban)(ban)既具有(you)防(fang)銹性(xing)能，又有(you)良好的(de)(de)涂裝性(xing)能。

樓(lou)承板(ban)(ban)(ban)(ban)(ban)組(zu)合板(ban)(ban)(ban)(ban)(ban)是一(yi)種十分合理(li)的(de)結構方式(shi)，它能夠(gou)按其各組(zu)成部件(jian)所(suo)處的(de)方位和(he)(he)特色，充(chong)分發(fa)揮鋼材(cai)抗(kang)拉和(he)(he)混凝土(tu)抗(kang)壓功(gong)能好(hao)(hao)的(de)長處，并具有杰出的(de)抗(kang)震(zhen)功(gong)能、施工(gong)功(gong)能。這(zhe)種結構現(xian)在被廣泛(fan)運用于國內(nei)外修建(jian)中，但在國內(nei)大都(dou)將樓(lou)承板(ban)(ban)(ban)(ban)(ban)當(dang)作(zuo)模(mo)板(ban)(ban)(ban)(ban)(ban)運用，而沒(mei)有充(chong)分發(fa)揮樓(lou)承板(ban)(ban)(ban)(ban)(ban)的(de)效果。 與一(yi)般(ban)鋼筋混凝土(tu)樓(lou)板(ban)(ban)(ban)(ban)(ban)比較，樓(lou)承板(ban)(ban)(ban)(ban)(ban)組(zu)合樓(lou)板(ban)(ban)(ban)(ban)(ban)具備以下長處：樓(lou)承板(ban)(ban)(ban)(ban)(ban)能夠(gou)作(zuo)為現(xian)澆混凝土(tu)的(de)模(mo)板(ban)(ban)(ban)(ban)(ban)。這(zhe)樣就省掉(diao)了施工(gong)中裝置和(he)(he)撤(che)除(chu)模(mo)板(ban)(ban)(ban)(ban)(ban)等工(gong)序，然后節約了時刻和(he)(he)勞動力;當(dang)樓(lou)承板(ban)(ban)(ban)(ban)(ban)裝置好(hao)(hao)今后將能夠(gou)作(zuo)為施工(gong)平臺(tai)運用。

彩(cai)(cai)(cai)鋼(gang)(gang)是(shi)(shi)(shi)指(zhi)彩(cai)(cai)(cai)涂鋼(gang)(gang)板(ban)(ban)，彩(cai)(cai)(cai)涂鋼(gang)(gang)板(ban)(ban)是(shi)(shi)(shi)一種帶有(you)(you)有(you)(you)機涂層(ceng)的(de)(de)(de)鋼(gang)(gang)板(ban)(ban)，傳(chuan)統的(de)(de)(de)涂層(ceng)分好幾(ji)類，氟碳涂層(ceng)的(de)(de)(de)，幾(ji)乎可以防(fang)腐20年。一般從鋼(gang)(gang)廠以卷(juan)筒的(de)(de)(de)形式分銷到各地。我們經常看(kan)到的(de)(de)(de)彩(cai)(cai)(cai)鋼(gang)(gang)板(ban)(ban)是(shi)(shi)(shi)指(zhi)加(jia)工(gong)好的(de)(de)(de)板(ban)(ban)材，厚度在50~100mm左(zuo)右(you)，它是(shi)(shi)(shi)由中(zhong)間的(de)(de)(de)填料(liao)和兩(liang)面的(de)(de)(de)彩(cai)(cai)(cai)鋼(gang)(gang)板(ban)(ban)組成。其中(zhong)，彩(cai)(cai)(cai)板(ban)(ban)厚度有(you)(you)0.4mm、0.5mm、0.6mm等不同的(de)(de)(de)厚度,中(zhong)間層(ceng)可以是(shi)(shi)(shi)聚胺(an)脂、巖綿或泡沫塑料(liao)等。由于有(you)(you)專(zhuan)用型材，所以用彩(cai)(cai)(cai)鋼(gang)(gang)板(ban)(ban)構(gou)筑(zhu)的(de)(de)(de)廠房建造速度很快（如(ru)非(fei)典時的(de)(de)(de)小湯山醫院），但強(qiang)度低。

鍍鋅帶鋼廠家鍍鋅鋼板的表面鍍鋅主要采用的方法是熱鍍鋅。廣西鍍鋅帶鋼熱(re)(re)鍍鋅(xin)(xin)是(shi)(shi)由較古老的熱(re)(re)鍍方法發展(zhan)而(er)來的，自從1836年(nian)法國把熱(re)(re)鍍鋅(xin)(xin)應用于(yu)(yu)工(gong)(gong)業以(yi)來，已(yi)(yi)經有(you)一百七十年(nian)的歷史了。然(ran)而(er)，熱(re)(re)鍍鋅(xin)(xin)工(gong)(gong)業是(shi)(shi)近三十年(nian)來伴(ban)隨冷(leng)軋帶鋼的飛(fei)速(su)發展(zhan)而(er)得(de)(de)到了大(da)規模發展(zhan)。鍍鋅(xin)(xin)溶液(ye)(ye)有(you)氰(qing)(qing)(qing)(qing)化(hua)物(wu)鍍液(ye)(ye)和(he)無氰(qing)(qing)(qing)(qing)鍍液(ye)(ye)兩類。氰(qing)(qing)(qing)(qing)化(hua)物(wu)鍍液(ye)(ye)中分微(wei)氰(qing)(qing)(qing)(qing)、低(di)氰(qing)(qing)(qing)(qing)、中氰(qing)(qing)(qing)(qing)、和(he)高氰(qing)(qing)(qing)(qing)幾類。無氰(qing)(qing)(qing)(qing)鍍液(ye)(ye)有(you)堿性鋅(xin)(xin)酸鹽鍍液(ye)(ye)、銨(an)鹽鍍液(ye)(ye)、硫酸鹽鍍液(ye)(ye)及無氨氯化(hua)物(wu)鍍液(ye)(ye)等。氰(qing)(qing)(qing)(qing)化(hua)鍍鋅(xin)(xin)溶液(ye)(ye)均鍍能力好，得(de)(de)到的鍍層光滑細致，在生產(chan)中被長(chang)期采用。但(dan)由于(yu)(yu)氰(qing)(qing)(qing)(qing)化(hua)物(wu)劇毒，對(dui)環境污(wu)染(ran)嚴重，近年(nian)來已(yi)(yi)趨(qu)向于(yu)(yu)采用低(di)氰(qing)(qing)(qing)(qing)、微(wei)氰(qing)(qing)(qing)(qing)、無氰(qing)(qing)(qing)(qing)鍍鋅(xin)(xin)溶液(ye)(ye)。
