鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)是為(wei)(wei)防止鋼(gang)板(ban)(ban)(ban)表(biao)面(mian)(mian)遭受腐蝕，延長其使用壽命，在鋼(gang)板(ban)(ban)(ban)表(biao)面(mian)(mian)涂(tu)以一層(ceng)金屬(shu)鋅(xin)(xin)(xin)(xin)(xin)，這(zhe)種(zhong)涂(tu)鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)薄鋼(gang)板(ban)(ban)(ban)稱為(wei)(wei)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)。按生產(chan)及加工(gong)方(fang)法可分為(wei)(wei)以下幾類：熱浸(jin)(jin)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。將(jiang)薄鋼(gang)板(ban)(ban)(ban)浸(jin)(jin)入熔 微商(shang)貨源解的(de)(de)鋅(xin)(xin)(xin)(xin)(xin)槽中，使其表(biao)面(mian)(mian)粘(zhan)附一層(ceng)鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)薄鋼(gang)板(ban)(ban)(ban)。目前主(zhu)要(yao)采用連(lian)續(xu)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)工(gong)藝(yi)生產(chan)，即把(ba)成卷(juan)的(de)(de)鋼(gang)板(ban)(ban)(ban)連(lian)續(xu)浸(jin)(jin)在熔解有鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)鍍(du)(du)槽中制(zhi)成鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)；合(he)金化鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。這(zhe)種(zhong)鋼(gang)板(ban)(ban)(ban)也(ye)是用熱浸(jin)(jin)法制(zhi)造，但在出槽后，立即把(ba)它加熱到５００℃左右，使其生成鋅(xin)(xin)(xin)(xin)(xin)和(he)鐵的(de)(de)合(he)金被膜。這(zhe)種(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)具有良好的(de)(de)涂(tu)料(liao)的(de)(de)密(mi)著性和(he)焊(han)接性。

鍍(du)(du)(du)(du)(du)鋅方管是(shi)一種具以熱(re)軋(ya)或冷軋(ya)鍍(du)(du)(du)(du)(du)鋅帶(dai)鋼(gang)或鍍(du)(du)(du)(du)(du)鋅卷板為(wei)(wei)坯料經(jing)冷彎曲加(jia)工(gong)成型后再(zai)經(jing)高(gao)頻(pin)焊接(jie)制成的(de)方形截面(mian)形狀尺寸的(de)空心方形的(de)截面(mian)型鋼(gang)鋼(gang)管；鍍(du)(du)(du)(du)(du)鋅卷或將事先做好的(de)冷彎空心型鋼(gang)管再(zai)經(jing)熱(re)浸鍍(du)(du)(du)(du)(du)鋅加(jia)工(gong)而(er)成的(de)鍍(du)(du)(du)(du)(du)鋅方矩管。鍍(du)(du)(du)(du)(du)鋅量是(shi)表示鍍(du)(du)(du)(du)(du)鋅板鋅層厚度的(de)一個普遍采用(yong)的(de)有效方法。鍍(du)(du)(du)(du)(du)鋅量的(de)單位(wei)為(wei)(wei)g/m2。鍍(du)(du)(du)(du)(du)鋅層通過鈍化(hua)處理(li)，可(ke)減少潮溫(wen)貯運(yun)條件下產生折銹蝕(白(bai)銹) 。但這種化(hua)學處理(li)的(de)防腐蝕性能是(shi)有限(xian)的(de)，而(er)且，妨礙(ai)大多數(shu)涂料的(de)附著性。這種處理(li)一般不用(yong)在鋅鐵(tie)合金鍍(du)(du)(du)(du)(du)層，除光整表面(mian)外，作為(wei)(wei)常規，生產廠對其他類型的(de)鍍(du)(du)(du)(du)(du)鋅層均進行鈍化(hua)處理(li)。

鍍(du)(du)(du)(du)鋅(xin)鋼板的表(biao)面鍍(du)(du)(du)(du)鋅(xin)主(zhu)要采(cai)用的方法是(shi)熱(re)鍍(du)(du)(du)(du)鋅(xin)。熱(re)鍍(du)(du)(du)(du)鋅(xin)是(shi)由較古老的熱(re)鍍(du)(du)(du)(du)方法發展(zhan)(zhan)而來(lai)(lai)的，自從1836年(nian)法國(guo)把熱(re)鍍(du)(du)(du)(du)鋅(xin)應用于工業以來(lai)(lai)，已(yi)(yi)經有一百七十年(nian)的歷(li)史了。然而，熱(re)鍍(du)(du)(du)(du)鋅(xin)工業是(shi)近三十年(nian)來(lai)(lai)伴隨冷軋(ya)帶鋼的飛速發展(zhan)(zhan)而得到了大(da)規模發展(zhan)(zhan)。鍍(du)(du)(du)(du)鋅(xin)溶(rong)液(ye)(ye)有氰(qing)(qing)化(hua)(hua)物鍍(du)(du)(du)(du)液(ye)(ye)和無(wu)氰(qing)(qing)鍍(du)(du)(du)(du)液(ye)(ye)兩類。氰(qing)(qing)化(hua)(hua)物鍍(du)(du)(du)(du)液(ye)(ye)中分(fen)微氰(qing)(qing)、低氰(qing)(qing)、中氰(qing)(qing)、和高氰(qing)(qing)幾類。無(wu)氰(qing)(qing)鍍(du)(du)(du)(du)液(ye)(ye)有堿性鋅(xin)酸鹽鍍(du)(du)(du)(du)液(ye)(ye)、銨鹽鍍(du)(du)(du)(du)液(ye)(ye)、硫酸鹽鍍(du)(du)(du)(du)液(ye)(ye)及無(wu)氨氯化(hua)(hua)物鍍(du)(du)(du)(du)液(ye)(ye)等。氰(qing)(qing)化(hua)(hua)鍍(du)(du)(du)(du)鋅(xin)溶(rong)液(ye)(ye)均鍍(du)(du)(du)(du)能力(li)好，得到的鍍(du)(du)(du)(du)層(ceng)光滑(hua)細致(zhi)，在生產(chan)中被長(chang)期采(cai)用。但由于氰(qing)(qing)化(hua)(hua)物劇(ju)毒，對(dui)環境(jing)污染(ran)嚴重(zhong)，近年(nian)來(lai)(lai)已(yi)(yi)趨(qu)向(xiang)于采(cai)用低氰(qing)(qing)、微氰(qing)(qing)、無(wu)氰(qing)(qing)鍍(du)(du)(du)(du)鋅(xin)溶(rong)液(ye)(ye)。
