彩涂板批發鍍鋅鋼板的表面鍍鋅主要采用的方法是熱鍍鋅。咸陽彩涂板熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)是由較古老的(de)熱(re)鍍(du)(du)(du)(du)方(fang)法發(fa)展(zhan)而來(lai)(lai)的(de)，自從1836年法國把熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)應用于工(gong)業以來(lai)(lai)，已經有一百(bai)七十年的(de)歷史(shi)了。然而，熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)工(gong)業是近三十年來(lai)(lai)伴隨冷軋(ya)帶鋼的(de)飛速發(fa)展(zhan)而得(de)到了大規模發(fa)展(zhan)。鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)液(ye)(ye)有氰(qing)(qing)(qing)化物(wu)(wu)鍍(du)(du)(du)(du)液(ye)(ye)和無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)(ye)兩類(lei)(lei)。氰(qing)(qing)(qing)化物(wu)(wu)鍍(du)(du)(du)(du)液(ye)(ye)中(zhong)分微氰(qing)(qing)(qing)、低氰(qing)(qing)(qing)、中(zhong)氰(qing)(qing)(qing)、和高氰(qing)(qing)(qing)幾類(lei)(lei)。無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)(ye)有堿(jian)性鋅(xin)(xin)酸(suan)鹽(yan)(yan)鍍(du)(du)(du)(du)液(ye)(ye)、銨鹽(yan)(yan)鍍(du)(du)(du)(du)液(ye)(ye)、硫酸(suan)鹽(yan)(yan)鍍(du)(du)(du)(du)液(ye)(ye)及無氨氯(lv)化物(wu)(wu)鍍(du)(du)(du)(du)液(ye)(ye)等。氰(qing)(qing)(qing)化鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)液(ye)(ye)均(jun)鍍(du)(du)(du)(du)能力好，得(de)到的(de)鍍(du)(du)(du)(du)層光滑細致，在生產(chan)中(zhong)被(bei)長期采用。但由于氰(qing)(qing)(qing)化物(wu)(wu)劇毒，對環境污染(ran)嚴(yan)重，近年來(lai)(lai)已趨向于采用低氰(qing)(qing)(qing)、微氰(qing)(qing)(qing)、無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)液(ye)(ye)。

用(yong)(yong)(yong)電鍍(du)(du)(du)(du)(du)法(fa)制(zhi)造這(zhe)種(zhong)鍍(du)(du)(du)(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)具(ju)有(you)良(liang)好(hao)的(de)(de)加工(gong)性。但鍍(du)(du)(du)(du)(du)層較薄，耐腐蝕性不如熱(re)浸(jin)法(fa)鍍(du)(du)(du)(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban)；單面(mian)(mian)鍍(du)(du)(du)(du)(du)和(he)雙面(mian)(mian)差鍍(du)(du)(du)(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。單面(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)，即只在一(yi)面(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)的(de)(de)產品。在焊(han)接、涂裝(zhuang)、防(fang)(fang)銹處(chu)理、加工(gong)等(deng)(deng)方面(mian)(mian)，具(ju)有(you)比雙面(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban)好(hao)的(de)(de)適應性。為(wei)克服單面(mian)(mian)未涂鋅(xin)的(de)(de)缺點，又(you)有(you)一(yi)種(zhong)在另面(mian)(mian)涂以薄層鋅(xin)的(de)(de)鍍(du)(du)(du)(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban)，即雙面(mian)(mian)差鍍(du)(du)(du)(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban)；合金、復(fu)合鍍(du)(du)(du)(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。它是用(yong)(yong)(yong)鋅(xin)和(he)其(qi)他(ta)金屬如鉛、鋅(xin)制(zhi)成合金乃至復(fu)合鍍(du)(du)(du)(du)(du)成的(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。這(zhe)種(zhong)鋼(gang)板(ban)(ban)(ban)(ban)(ban)既(ji)具(ju)有(you)防(fang)(fang)銹性能(neng)，又(you)有(you)良(liang)好(hao)的(de)(de)涂裝(zhuang)性能(neng)。 除(chu)上述五種(zhong)外，還有(you)彩色鍍(du)(du)(du)(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)、印花涂裝(zhuang)鍍(du)(du)(du)(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)、聚氯乙烯疊層鍍(du)(du)(du)(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)等(deng)(deng)。但目(mu)前(qian)常用(yong)(yong)(yong)的(de)(de)仍為(wei)熱(re)浸(jin)鍍(du)(du)(du)(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban)。 鍍(du)(du)(du)(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)按用(yong)(yong)(yong)途又(you)可(ke)分為(wei)一(yi)般(ban)用(yong)(yong)(yong)、屋頂(ding)用(yong)(yong)(yong)、建筑外側(ce)板(ban)(ban)(ban)(ban)(ban)用(yong)(yong)(yong)、結構用(yong)(yong)(yong)、瓦(wa)壟(long)板(ban)(ban)(ban)(ban)(ban)用(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)和(he)深沖用(yong)(yong)(yong)等(deng)(deng)鍍(du)(du)(du)(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。

鍍(du)(du)(du)鋅(xin)(xin)(xin)帶(dai)(dai)(dai)鋼(gang)(gang)(gang)的鋅(xin)(xin)(xin)層特性 電鍍(du)(du)(du)鋅(xin)(xin)(xin)層是不能形(xing)成(cheng)鋅(xin)(xin)(xin)花的，熱(re)(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)層則有(you)鋅(xin)(xin)(xin)花，其形(xing)成(cheng)過程如下(xia)：當鍍(du)(du)(du)鋅(xin)(xin)(xin)帶(dai)(dai)(dai)從(cong)(cong)鋅(xin)(xin)(xin)鍋出來(lai)后，經氣刀(dao)的噴(pen)吹(chui)，大量鋅(xin)(xin)(xin)液被(bei)吹(chui)回鋅(xin)(xin)(xin)鍋，這(zhe)時帶(dai)(dai)(dai)鋼(gang)(gang)(gang)表面還有(you)純鋅(xin)(xin)(xin)層，呈液 態附(fu)在鋼(gang)(gang)(gang)板表面，在鋼(gang)(gang)(gang)板表面形(xing)成(cheng)大量結晶(jing)核，隨著鋼(gang)(gang)(gang)板上升冷(leng)卻(que)，使結晶(jing)核慢慢長成(cheng)鋅(xin)(xin)(xin)花。冷(leng)卻(que)速度(du)越(yue)快鋅(xin)(xin)(xin)花越(yue)小，冷(leng)卻(que)速度(du)越(yue)慢鋅(xin)(xin)(xin)花越(yue)大。熱(re)(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)帶(dai)(dai)(dai)鋼(gang)(gang)(gang)在我(wo)國市場一直是緊缺品種(zhong)。從(cong)(cong)20世紀(ji)90年代中(zhong)期以來(lai)，每年都要從(cong)(cong)國外進(jin)口80-100萬t左右。隨著國內經濟的發展，尤其是汽車、家電及建筑業(ye)的發展，對鍍(du)(du)(du)鋅(xin)(xin)(xin)帶(dai)(dai)(dai)鋼(gang)(gang)(gang)的需求量也大大增加。

鍍(du)(du)鋅(xin)(xin)卷(juan)分(fen)熱鍍(du)(du)鋅(xin)(xin)和(he)電鍍(du)(du)鋅(xin)(xin)兩種(zhong)(zhong)，熱鍍(du)(du)鋅(xin)(xin)鍍(du)(du)鋅(xin)(xin)層厚，具有(you)(you)鍍(du)(du)層均勻，附(fu)著力強，使(shi)用(yong)壽(shou)命(ming)長等(deng)優點。電鍍(du)(du)鋅(xin)(xin)成本低，表(biao)面(mian)不(bu)(bu)是很(hen)光滑，其本身的(de)(de)(de)耐腐蝕(shi)(shi)性(xing)比(bi)熱鍍(du)(du)鋅(xin)(xin)管相差很(hen)多。提起(qi)鍍(du)(du)鋅(xin)(xin)管，可能(neng)沒(mei)接觸過建材的(de)(de)(de)朋友并不(bu)(bu)了解。從(cong)1935年建立一條連續涂層鋼板線(xian)開始，彩(cai)涂板得到了廣泛應用(yong)，目(mu)前彩(cai)涂板的(de)(de)(de)品種(zhong)(zhong)繁多，大約超過600種(zhong)(zhong)，彩(cai)涂板兼有(you)(you)機聚(ju)合(he)物(wu)與鋼板兩者的(de)(de)(de)優點，既有(you)(you)有(you)(you)機聚(ju)合(he)物(wu)的(de)(de)(de)良好(hao)著色性(xing)、成型(xing)性(xing)、耐蝕(shi)(shi)性(xing)、裝飾性(xing)、又有(you)(you)鋼板的(de)(de)(de)高強度和(he)易(yi)加工性(xing)，能(neng)很(hen)容易(yi)地(di)進行沖壓裁(cai)剪、彎曲、深沖等(deng)加工。
