鍍(du)鋅(xin)鋼板的表面鍍(du)鋅(xin)主要采(cai)用(yong)的方(fang)法是(shi)熱(re)(re)鍍(du)鋅(xin)。熱(re)(re)鍍(du)鋅(xin)是(shi)由較古老的熱(re)(re)鍍(du)方(fang)法發展而(er)(er)來(lai)的，自(zi)從1836年(nian)法國把熱(re)(re)鍍(du)鋅(xin)應(ying)用(yong)于(yu)工(gong)業以來(lai)，已經有一百七(qi)十年(nian)的歷史(shi)了。然而(er)(er)，熱(re)(re)鍍(du)鋅(xin)工(gong)業是(shi)近三(san)十年(nian)來(lai)伴隨冷(leng)軋帶鋼的飛速發展而(er)(er)得(de)到(dao)了大規模發展。鍍(du)鋅(xin)溶液(ye)(ye)有氰(qing)(qing)(qing)(qing)化(hua)(hua)(hua)物(wu)(wu)鍍(du)液(ye)(ye)和(he)無(wu)氰(qing)(qing)(qing)(qing)鍍(du)液(ye)(ye)兩類。氰(qing)(qing)(qing)(qing)化(hua)(hua)(hua)物(wu)(wu)鍍(du)液(ye)(ye)中(zhong)(zhong)分微氰(qing)(qing)(qing)(qing)、低氰(qing)(qing)(qing)(qing)、中(zhong)(zhong)氰(qing)(qing)(qing)(qing)、和(he)高氰(qing)(qing)(qing)(qing)幾類。無(wu)氰(qing)(qing)(qing)(qing)鍍(du)液(ye)(ye)有堿性鋅(xin)酸(suan)鹽(yan)(yan)鍍(du)液(ye)(ye)、銨鹽(yan)(yan)鍍(du)液(ye)(ye)、硫酸(suan)鹽(yan)(yan)鍍(du)液(ye)(ye)及無(wu)氨(an)氯化(hua)(hua)(hua)物(wu)(wu)鍍(du)液(ye)(ye)等。氰(qing)(qing)(qing)(qing)化(hua)(hua)(hua)鍍(du)鋅(xin)溶液(ye)(ye)均鍍(du)能力好(hao)，得(de)到(dao)的鍍(du)層光滑細致，在生(sheng)產(chan)中(zhong)(zhong)被長期采(cai)用(yong)。但(dan)由于(yu)氰(qing)(qing)(qing)(qing)化(hua)(hua)(hua)物(wu)(wu)劇毒，對(dui)環境污染嚴重(zhong)，近年(nian)來(lai)已趨向(xiang)于(yu)采(cai)用(yong)低氰(qing)(qing)(qing)(qing)、微氰(qing)(qing)(qing)(qing)、無(wu)氰(qing)(qing)(qing)(qing)鍍(du)鋅(xin)溶液(ye)(ye)。

鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)是為防止鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)表(biao)面(mian)(mian)遭受(shou)腐蝕(shi)，延(yan)長其使用(yong)(yong)壽(shou)命，在(zai)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)表(biao)面(mian)(mian)涂(tu)以一層(ceng)金屬(shu)鋅(xin)(xin)(xin)(xin)，這(zhe)(zhe)種(zhong)(zhong)(zhong)涂(tu)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)(de)薄鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)稱(cheng)為鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)。鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)也(ye)(ye)是用(yong)(yong)熱(re)浸(jin)法制造，但在(zai)出(chu)槽(cao)后，立即把它加(jia)熱(re)到(dao)500℃左(zuo)(zuo)右，使其生成(cheng)(cheng)鋅(xin)(xin)(xin)(xin)和鐵的(de)(de)(de)(de)合(he)(he)(he)金被膜。這(zhe)(zhe)種(zhong)(zhong)(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)卷具(ju)有(you)(you)良(liang)好的(de)(de)(de)(de)涂(tu)料(liao)的(de)(de)(de)(de)密(mi)著性(xing)(xing)和焊接(jie)(jie)性(xing)(xing)。合(he)(he)(he)金化鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。這(zhe)(zhe)種(zhong)(zhong)(zhong)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)也(ye)(ye)是用(yong)(yong)熱(re)浸(jin)法制造，但在(zai)出(chu)槽(cao)后，立即把它加(jia)熱(re)到(dao)500℃左(zuo)(zuo)右，使其生成(cheng)(cheng)鋅(xin)(xin)(xin)(xin)和鐵的(de)(de)(de)(de)合(he)(he)(he)金被膜。這(zhe)(zhe)種(zhong)(zhong)(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)具(ju)有(you)(you)良(liang)好的(de)(de)(de)(de)涂(tu)料(liao)的(de)(de)(de)(de)密(mi)著性(xing)(xing)和焊接(jie)(jie)性(xing)(xing)。熱(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。將(jiang)薄鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)浸(jin)入熔(rong)解的(de)(de)(de)(de)鋅(xin)(xin)(xin)(xin)槽(cao)中(zhong)，使其表(biao)面(mian)(mian)粘附一層(ceng)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)(de)薄鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。目前主(zhu)要采用(yong)(yong)連續(xu)鍍(du)(du)鋅(xin)(xin)(xin)(xin)工藝生產(chan)，即把成(cheng)(cheng)卷的(de)(de)(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)連續(xu)浸(jin)在(zai)熔(rong)解有(you)(you)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)(de)鍍(du)(du)槽(cao)中(zhong)制成(cheng)(cheng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。合(he)(he)(he)金、復(fu)合(he)(he)(he)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。它是用(yong)(yong)鋅(xin)(xin)(xin)(xin)和其他(ta)金屬(shu)如鉛、鋅(xin)(xin)(xin)(xin)制成(cheng)(cheng)合(he)(he)(he)金乃至復(fu)合(he)(he)(he)鍍(du)(du)成(cheng)(cheng)的(de)(de)(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)。這(zhe)(zhe)種(zhong)(zhong)(zhong)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)既具(ju)有(you)(you)防銹性(xing)(xing)能，又有(you)(you)良(liang)好的(de)(de)(de)(de)涂(tu)裝性(xing)(xing)能。

鍍鋅板廠家鍍鋅是一種經常采用的經濟而有效的防腐方法。鋅產量的一半左右均用于此種工藝。鍍鋅卷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，這種涂鋅的鋼板稱為鍍鋅卷。遵義鍍鋅板鍍鋅卷主要用于(yu)建筑、家電(dian)、汽車、容器、交(jiao)通及家業(ye)等(deng)(deng)領域。特(te)別是鋼結(jie)構(gou)建筑、汽車制造、鋼板倉制造等(deng)(deng)行業(ye)。耐腐蝕(shi)強(qiang)、表面質量好、得(de)利于(yu)深加(jia)工、經濟實(shi)用等(deng)(deng)。有關產品標準都列明(ming)鍍鋅卷推薦的標準厚(hou)(hou)度(du)、長(chang)度(du)和寬度(du)及其允許偏(pian)(pian)差。鍍鋅卷厚(hou)(hou)度(du)偏(pian)(pian)差一(yi)般在(zai)(zai)0.05mm，長(chang)寬偏(pian)(pian)差一(yi)般在(zai)(zai)5mm ，板材的厚(hou)(hou)度(du)一(yi)般在(zai)(zai)0.2-3.2之間 。
