彩(cai)(cai)(cai)鋼(gang)是(shi)(shi)(shi)(shi)指彩(cai)(cai)(cai)涂(tu)鋼(gang)板(ban)(ban)，彩(cai)(cai)(cai)涂(tu)鋼(gang)板(ban)(ban)是(shi)(shi)(shi)(shi)一種帶有(you)有(you)機(ji)涂(tu)層(ceng)(ceng)(ceng)的(de)(de)鋼(gang)板(ban)(ban)，傳(chuan)統的(de)(de)涂(tu)層(ceng)(ceng)(ceng)分好(hao)幾(ji)類，氟碳涂(tu)層(ceng)(ceng)(ceng)的(de)(de)，幾(ji)乎(hu)可以防腐20年。一般(ban)從(cong)鋼(gang)廠以卷筒(tong)的(de)(de)形式分銷到各地。我們經常看到的(de)(de)彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)是(shi)(shi)(shi)(shi)指加工好(hao)的(de)(de)板(ban)(ban)材，厚(hou)(hou)度(du)(du)在50~100mm左右(you)，它是(shi)(shi)(shi)(shi)由(you)中(zhong)間的(de)(de)填料(liao)和兩面的(de)(de)彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)組成。其中(zhong)，彩(cai)(cai)(cai)板(ban)(ban)厚(hou)(hou)度(du)(du)有(you)0.4mm、0.5mm、0.6mm等不同的(de)(de)厚(hou)(hou)度(du)(du),中(zhong)間層(ceng)(ceng)(ceng)可以是(shi)(shi)(shi)(shi)聚(ju)胺脂、巖(yan)綿(mian)或泡沫(mo)塑料(liao)等。由(you)于有(you)專用(yong)型材，所(suo)以用(yong)彩(cai)(cai)(cai)鋼(gang)板(ban)(ban)構筑的(de)(de)廠房建造速度(du)(du)很快（如非典時(shi)的(de)(de)小湯山醫院），但強度(du)(du)低。

用(yong)(yong)(yong)電鍍(du)(du)(du)(du)法制造這種(zhong)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)具(ju)有良(liang)好的(de)加(jia)工性(xing)。但(dan)鍍(du)(du)(du)(du)層較薄，耐腐蝕性(xing)不如熱(re)(re)浸法鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)；單(dan)面(mian)(mian)(mian)(mian)鍍(du)(du)(du)(du)和雙面(mian)(mian)(mian)(mian)差(cha)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)。單(dan)面(mian)(mian)(mian)(mian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)，即(ji)只在一面(mian)(mian)(mian)(mian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)的(de)產品(pin)。在焊接、涂(tu)裝、防銹(xiu)處理、加(jia)工等方面(mian)(mian)(mian)(mian)，具(ju)有比(bi)雙面(mian)(mian)(mian)(mian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)好的(de)適應性(xing)。為克服單(dan)面(mian)(mian)(mian)(mian)未涂(tu)鋅(xin)(xin)(xin)(xin)的(de)缺點，又有一種(zhong)在另面(mian)(mian)(mian)(mian)涂(tu)以薄層鋅(xin)(xin)(xin)(xin)的(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)，即(ji)雙面(mian)(mian)(mian)(mian)差(cha)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)；合(he)金、復合(he)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)。它是用(yong)(yong)(yong)鋅(xin)(xin)(xin)(xin)和其(qi)他金屬如鉛、鋅(xin)(xin)(xin)(xin)制成合(he)金乃至復合(he)鍍(du)(du)(du)(du)成的(de)鋼(gang)(gang)板(ban)。這種(zhong)鋼(gang)(gang)板(ban)既具(ju)有防銹(xiu)性(xing)能，又有良(liang)好的(de)涂(tu)裝性(xing)能。 除上述五種(zhong)外(wai)，還有彩(cai)色鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)、印花涂(tu)裝鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)、聚氯乙(yi)烯疊層鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)等。但(dan)目前常用(yong)(yong)(yong)的(de)仍為熱(re)(re)浸鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)。 鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)按(an)用(yong)(yong)(yong)途又可分為一般用(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)、建筑(zhu)外(wai)側板(ban)用(yong)(yong)(yong)、結(jie)構用(yong)(yong)(yong)、瓦壟(long)板(ban)用(yong)(yong)(yong)、拉伸(shen)用(yong)(yong)(yong)和深沖用(yong)(yong)(yong)等鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)。

鍍(du)(du)(du)(du)鋅(xin)(xin)鋼板的(de)(de)表面鍍(du)(du)(du)(du)鋅(xin)(xin)主要采用(yong)的(de)(de)方法(fa)是熱(re)(re)鍍(du)(du)(du)(du)鋅(xin)(xin)。熱(re)(re)鍍(du)(du)(du)(du)鋅(xin)(xin)是由較古老的(de)(de)熱(re)(re)鍍(du)(du)(du)(du)方法(fa)發(fa)展而來的(de)(de)，自從(cong)1836年法(fa)國把(ba)熱(re)(re)鍍(du)(du)(du)(du)鋅(xin)(xin)應用(yong)于(yu)工業以來，已(yi)經有一百七十(shi)年的(de)(de)歷史了。然而，熱(re)(re)鍍(du)(du)(du)(du)鋅(xin)(xin)工業是近三十(shi)年來伴隨冷軋帶鋼的(de)(de)飛速發(fa)展而得(de)到了大規模發(fa)展。鍍(du)(du)(du)(du)鋅(xin)(xin)溶液(ye)(ye)有氰(qing)(qing)(qing)(qing)化(hua)(hua)(hua)物(wu)(wu)鍍(du)(du)(du)(du)液(ye)(ye)和無氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)(ye)兩類。氰(qing)(qing)(qing)(qing)化(hua)(hua)(hua)物(wu)(wu)鍍(du)(du)(du)(du)液(ye)(ye)中(zhong)分微(wei)氰(qing)(qing)(qing)(qing)、低氰(qing)(qing)(qing)(qing)、中(zhong)氰(qing)(qing)(qing)(qing)、和高氰(qing)(qing)(qing)(qing)幾類。無氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)(ye)有堿性鋅(xin)(xin)酸(suan)鹽鍍(du)(du)(du)(du)液(ye)(ye)、銨鹽鍍(du)(du)(du)(du)液(ye)(ye)、硫酸(suan)鹽鍍(du)(du)(du)(du)液(ye)(ye)及無氨氯化(hua)(hua)(hua)物(wu)(wu)鍍(du)(du)(du)(du)液(ye)(ye)等。氰(qing)(qing)(qing)(qing)化(hua)(hua)(hua)鍍(du)(du)(du)(du)鋅(xin)(xin)溶液(ye)(ye)均鍍(du)(du)(du)(du)能力好，得(de)到的(de)(de)鍍(du)(du)(du)(du)層光滑細致，在生(sheng)產中(zhong)被長期采用(yong)。但由于(yu)氰(qing)(qing)(qing)(qing)化(hua)(hua)(hua)物(wu)(wu)劇毒(du)，對環境污染(ran)嚴重(zhong)，近年來已(yi)趨(qu)向于(yu)采用(yong)低氰(qing)(qing)(qing)(qing)、微(wei)氰(qing)(qing)(qing)(qing)、無氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)鋅(xin)(xin)溶液(ye)(ye)。

鍍鋅價格鍍鋅鋼板是為防止鋼板表面遭受腐蝕，延長其使用壽命，在鋼板表面涂以一層金屬鋅，這種涂鋅的薄鋼板稱為鍍鋅板。酒鋼鍍鋅價格按生產(chan)及(ji)加(jia)工方(fang)法(fa)可(ke)分為以下(xia)幾(ji)類：熱浸鍍(du)(du)鋅(xin)鋼板(ban)(ban)(ban)。將薄鋼板(ban)(ban)(ban)浸入熔 微商貨源解的鋅(xin)槽(cao)(cao)中，使其表面粘附一(yi)層鋅(xin)的薄鋼板(ban)(ban)(ban)。目前主要采用連續(xu)鍍(du)(du)鋅(xin)工藝生產(chan)，即把成(cheng)卷的鋼板(ban)(ban)(ban)連續(xu)浸在(zai)熔解有鋅(xin)的鍍(du)(du)槽(cao)(cao)中制(zhi)(zhi)成(cheng)鍍(du)(du)鋅(xin)鋼板(ban)(ban)(ban)；合金(jin)化鍍(du)(du)鋅(xin)鋼板(ban)(ban)(ban)。這種(zhong)鋼板(ban)(ban)(ban)也是用熱浸法(fa)制(zhi)(zhi)造，但在(zai)出(chu)槽(cao)(cao)后，立即把它加(jia)熱到５００℃左右，使其生成(cheng)鋅(xin)和鐵的合金(jin)被膜。這種(zhong)鍍(du)(du)鋅(xin)板(ban)(ban)(ban)具有良(liang)好的涂料(liao)的密著(zhu)性和焊接(jie)性。
