鍍(du)(du)(du)鋅(xin)鋼板的表面鍍(du)(du)(du)鋅(xin)主要(yao)采用的方法(fa)(fa)是(shi)(shi)熱(re)(re)鍍(du)(du)(du)鋅(xin)。熱(re)(re)鍍(du)(du)(du)鋅(xin)是(shi)(shi)由(you)較古(gu)老的熱(re)(re)鍍(du)(du)(du)方法(fa)(fa)發(fa)展而(er)來(lai)(lai)的，自(zi)從(cong)1836年(nian)(nian)(nian)法(fa)(fa)國把(ba)熱(re)(re)鍍(du)(du)(du)鋅(xin)應用于(yu)工(gong)業(ye)以來(lai)(lai)，已經有一百七十年(nian)(nian)(nian)的歷(li)史(shi)了。然而(er)，熱(re)(re)鍍(du)(du)(du)鋅(xin)工(gong)業(ye)是(shi)(shi)近三十年(nian)(nian)(nian)來(lai)(lai)伴隨冷(leng)軋(ya)帶鋼的飛速發(fa)展而(er)得(de)到(dao)了大(da)規模發(fa)展。鍍(du)(du)(du)鋅(xin)溶液(ye)(ye)(ye)有氰(qing)(qing)(qing)化(hua)(hua)物(wu)(wu)鍍(du)(du)(du)液(ye)(ye)(ye)和無(wu)氰(qing)(qing)(qing)鍍(du)(du)(du)液(ye)(ye)(ye)兩類(lei)。氰(qing)(qing)(qing)化(hua)(hua)物(wu)(wu)鍍(du)(du)(du)液(ye)(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(ji)類(lei)。無(wu)氰(qing)(qing)(qing)鍍(du)(du)(du)液(ye)(ye)(ye)有堿性鋅(xin)酸鹽鍍(du)(du)(du)液(ye)(ye)(ye)、銨鹽鍍(du)(du)(du)液(ye)(ye)(ye)、硫(liu)酸鹽鍍(du)(du)(du)液(ye)(ye)(ye)及無(wu)氨氯化(hua)(hua)物(wu)(wu)鍍(du)(du)(du)液(ye)(ye)(ye)等(deng)。氰(qing)(qing)(qing)化(hua)(hua)鍍(du)(du)(du)鋅(xin)溶液(ye)(ye)(ye)均鍍(du)(du)(du)能力好，得(de)到(dao)的鍍(du)(du)(du)層光滑細(xi)致(zhi)，在(zai)生產中(zhong)被長(chang)期(qi)采用。但由(you)于(yu)氰(qing)(qing)(qing)化(hua)(hua)物(wu)(wu)劇毒，對環(huan)境污(wu)染嚴重，近年(nian)(nian)(nian)來(lai)(lai)已趨向于(yu)采用低氰(qing)(qing)(qing)、微氰(qing)(qing)(qing)、無(wu)氰(qing)(qing)(qing)鍍(du)(du)(du)鋅(xin)溶液(ye)(ye)(ye)。

鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)為基板(ban)(ban)(ban)(ban)(ban)的(de)(de)彩涂(tu)(tu)(tu)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，除有(you)鋅(xin)(xin)保護外，鋅(xin)(xin)層(ceng)上(shang)(shang)的(de)(de)有(you)機(ji)涂(tu)(tu)(tu)層(ceng)起(qi)了覆蓋隔離作用，可防止鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)生銹，使用壽命比鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)更(geng)長，據介紹涂(tu)(tu)(tu)層(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的(de)(de)使用壽命比鍍鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)長50%。在(zai)連續機(ji)組(zu)上(shang)(shang)以(yi)冷(leng)軋帶(dai)(dai)鋼(gang)(gang)，鍍鋅(xin)(xin)帶(dai)(dai)鋼(gang)(gang)（電鍍鋅(xin)(xin)和(he)(he)熱鍍鋅(xin)(xin)）為基板(ban)(ban)(ban)(ban)(ban)，經過(guo)表面預處理(li)（脫脂和(he)(he)化學處理(li)），用輥涂(tu)(tu)(tu)的(de)(de)方法(fa)，涂(tu)(tu)(tu)上(shang)(shang)一(yi)層(ceng)或多層(ceng)液態涂(tu)(tu)(tu)料(liao)，經過(guo)烘烤和(he)(he)冷(leng)卻(que)所得的(de)(de)板(ban)(ban)(ban)(ban)(ban)材(cai)即為涂(tu)(tu)(tu)層(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。由于涂(tu)(tu)(tu)層(ceng)可以(yi)有(you)各種不同的(de)(de)顏(yan)色，習慣上(shang)(shang)把涂(tu)(tu)(tu)層(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)叫做彩色涂(tu)(tu)(tu)層(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。又由于涂(tu)(tu)(tu)層(ceng)是在(zai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)成型加(jia)工之(zhi)前進行的(de)(de)，在(zai)國(guo)外這叫做預涂(tu)(tu)(tu)層(ceng)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。

彩涂板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。酒鋼彩涂板價格按(an)生產(chan)及加(jia)工方法(fa)可分為以下幾類：熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)。將薄鋼(gang)板(ban)(ban)浸入(ru)熔(rong) 微商(shang)貨源解的鋅(xin)(xin)(xin)槽(cao)中，使其(qi)表面粘(zhan)附一層鋅(xin)(xin)(xin)的薄鋼(gang)板(ban)(ban)。目前主(zhu)要采用(yong)連(lian)續鍍(du)(du)(du)鋅(xin)(xin)(xin)工藝生產(chan)，即把成卷(juan)的鋼(gang)板(ban)(ban)連(lian)續浸在熔(rong)解有鋅(xin)(xin)(xin)的鍍(du)(du)(du)槽(cao)中制(zhi)成鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)；合金化鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)。這種鋼(gang)板(ban)(ban)也(ye)是用(yong)熱(re)浸法(fa)制(zhi)造，但在出槽(cao)后，立即把它加(jia)熱(re)到５００℃左右，使其(qi)生成鋅(xin)(xin)(xin)和鐵(tie)的合金被膜。這種鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)具(ju)有良好的涂(tu)料的密著性(xing)和焊接性(xing)。
