重慶鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)按生(sheng)產(chan)及加工(gong)方法可(ke)分(fen)為以下幾類： 熱(re)浸(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。將薄鋼(gang)板(ban)(ban)(ban)浸(jin)入熔解(jie)的(de)(de)(de)(de)鋅(xin)(xin)(xin)(xin)槽(cao)中，使其表面粘附一層(ceng)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)(de)薄鋼(gang)板(ban)(ban)(ban)。目(mu)前主要采用(yong)連續(xu)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)工(gong)藝生(sheng)產(chan)，即(ji)把成(cheng)卷(juan)的(de)(de)(de)(de)鋼(gang)板(ban)(ban)(ban)連續(xu)浸(jin)在熔解(jie)有(you)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)(de)鍍(du)(du)(du)槽(cao)中制(zhi)成(cheng)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)； 合(he)金(jin)化鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。為克服單(dan)面未(wei)涂鋅(xin)(xin)(xin)(xin)的(de)(de)(de)(de)缺點，又有(you)一種(zhong)在另面涂以薄層(ceng)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)，即(ji)雙面差(cha)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)；合(he)金(jin)、復(fu)合(he)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。它是用(yong)鋅(xin)(xin)(xin)(xin)和其他金(jin)屬如鉛、鋅(xin)(xin)(xin)(xin)制(zhi)成(cheng)合(he)金(jin)乃至復(fu)合(he)鍍(du)(du)(du)成(cheng)的(de)(de)(de)(de)鋼(gang)板(ban)(ban)(ban)。這(zhe)種(zhong)鋼(gang)板(ban)(ban)(ban)既具有(you)防銹(xiu)性(xing)能，又有(you)良好的(de)(de)(de)(de)涂裝(zhuang)性(xing)能。

熱(re)(re)鍍(du)(du)(du)鋅(xin)(xin)板(ban)和(he)電(dian)鍍(du)(du)(du)鋅(xin)(xin)板(ban)在鍍(du)(du)(du)鋅(xin)(xin)量上有很大的差別，就像山東(dong)彩涂卷）。熱(re)(re)鍍(du)(du)(du)鋅(xin)(xin)的鍍(du)(du)(du)鋅(xin)(xin)量不可(ke)能太小，一(yi)般(ban)(ban)較小為雙面50～60g／m2，較大可(ke)達600g／m2。電(dian)鍍(du)(du)(du)鋅(xin)(xin)板(ban)的鍍(du)(du)(du)鋅(xin)(xin)層(ceng)可(ke)以很薄，較小達15g／m2，但要求鍍(du)(du)(du)層(ceng)較厚(hou)的話則(ze)生產線(xian)速(su)度很慢，不適應現代化機組的工藝特點(dian)，一(yi)般(ban)(ban)較大為lO0g／m2左(zuo)右。正(zheng)因為如此，電(dian)鍍(du)(du)(du)鋅(xin)(xin)板(ban)的生產受到很大的限制。工一(yi)般(ban)(ban)電(dian)鍍(du)(du)(du)鋅(xin)(xin)比較多，適用于(yu)(yu)小部件；熱(re)(re)鍍(du)(du)(du)鋅(xin)(xin)一(yi)般(ban)(ban)用于(yu)(yu)電(dian)力設備(bei)和(he)構(gou)件，適用于(yu)(yu)大的部件和(he)設備(bei)。當(dang)然他們的價(jia)格也相(xiang)對便(bian)宜一(yi)些。建設部已正(zheng)式下(xia)文(wen)，淘汰技(ji)術落后(hou)的冷鍍(du)(du)(du)鋅(xin)(xin)管，不準用冷鍍(du)(du)(du)鋅(xin)(xin)管作水(shui)、煤氣管。

冷軋板批發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。攀鋼冷軋板批發按生(sheng)產及加工方法可分(fen)為以下幾(ji)類：熱(re)(re)浸(jin)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)。將薄鋼(gang)板(ban)浸(jin)入熔(rong) 微商貨(huo)源(yuan)解(jie)的(de)鋅(xin)(xin)(xin)槽(cao)中(zhong)，使其表面(mian)粘附一(yi)層鋅(xin)(xin)(xin)的(de)薄鋼(gang)板(ban)。目前主要采用連(lian)續鍍(du)鋅(xin)(xin)(xin)工藝生(sheng)產，即把成(cheng)(cheng)卷的(de)鋼(gang)板(ban)連(lian)續浸(jin)在(zai)熔(rong)解(jie)有鋅(xin)(xin)(xin)的(de)鍍(du)槽(cao)中(zhong)制(zhi)(zhi)成(cheng)(cheng)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)；合金化(hua)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)。這種鋼(gang)板(ban)也(ye)是用熱(re)(re)浸(jin)法制(zhi)(zhi)造，但在(zai)出槽(cao)后(hou)，立即把它加熱(re)(re)到５００℃左(zuo)右(you)，使其生(sheng)成(cheng)(cheng)鋅(xin)(xin)(xin)和(he)鐵的(de)合金被(bei)膜(mo)。這種鍍(du)鋅(xin)(xin)(xin)板(ban)具(ju)有良好的(de)涂(tu)料(liao)的(de)密(mi)著性和(he)焊接(jie)性。

鍍(du)(du)(du)鋅(xin)(xin)鋼板(ban)(ban)按用(yong)(yong)(yong)途又可(ke)分為一般用(yong)(yong)(yong)、屋頂(ding)用(yong)(yong)(yong)、建(jian)筑(zhu)外(wai)側板(ban)(ban)用(yong)(yong)(yong)、結構用(yong)(yong)(yong)、瓦壟(long)板(ban)(ban)用(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)和深(shen)沖(chong)用(yong)(yong)(yong)等鍍(du)(du)(du)鋅(xin)(xin)鋼板(ban)(ban)。熱(re)(re)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)主要應用(yong)(yong)(yong)于建(jian)筑(zhu)外(wai)用(yong)(yong)(yong)，建(jian)筑(zhu)內用(yong)(yong)(yong)，民(min)用(yong)(yong)(yong)，門窗，家具，機械，電子及家用(yong)(yong)(yong)電器等領域。也有機箱用(yong)(yong)(yong)這(zhe)個，不過熱(re)(re)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)不放輻射的(de)。空調(diao)，冰箱，微波爐及其(qi)類似家電背面的(de)那個板(ban)(ban)就(jiu)是(shi)熱(re)(re)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)。鍍(du)(du)(du)鋅(xin)(xin)層通過鈍(dun)化處理(li)，可(ke)減少潮溫(wen)貯運(yun)條件(jian)下產(chan)生(sheng)折(zhe)銹蝕(shi)(白(bai)銹) 。但這(zhe)種化學處理(li)的(de)防腐蝕(shi)性(xing)能是(shi)有限的(de)，而(er)且，妨礙大多數涂料(liao)的(de)附著性(xing)。這(zhe)種處理(li)一般不用(yong)(yong)(yong)在(zai)鋅(xin)(xin)鐵合(he)金鍍(du)(du)(du)層，除光整表面外(wai)，作為常規，生(sheng)產(chan)廠(chang)對其(qi)他類型的(de)鍍(du)(du)(du)鋅(xin)(xin)層均進行鈍(dun)化處理(li)。

鍍鋅(xin)是一(yi)(yi)種(zhong)經(jing)常采用的(de)經(jing)濟(ji)而有(you)效的(de)防腐(fu)方法。鋅(xin)產量(liang)的(de)一(yi)(yi)半左右均用于此種(zhong)工(gong)藝(yi)。鍍鋅(xin)卷(juan)(juan)是為防止(zhi)鋼(gang)板(ban)(ban)表面(mian)(mian)遭受腐(fu)蝕延長(chang)其(qi)使(shi)用壽(shou)命，在鋼(gang)板(ban)(ban)表面(mian)(mian)涂以一(yi)(yi)層金屬鋅(xin)，這種(zhong)涂鋅(xin)的(de)鋼(gang)板(ban)(ban)稱為鍍鋅(xin)卷(juan)(juan)。鍍鋅(xin)卷(juan)(juan)主(zhu)要用于建(jian)筑、家電、汽(qi)車(che)、容(rong)器、交通及家業等領(ling)域(yu)。特別是鋼(gang)結構建(jian)筑、汽(qi)車(che)制造(zao)、鋼(gang)板(ban)(ban)倉(cang)制造(zao)等行業。耐腐(fu)蝕強、表面(mian)(mian)質(zhi)量(liang)好(hao)、得利于深加工(gong)、經(jing)濟(ji)實用等。有(you)關產品標準都列明鍍鋅(xin)卷(juan)(juan)推薦的(de)標準厚度(du)、長(chang)度(du)和寬(kuan)度(du)及其(qi)允許偏(pian)差。鍍鋅(xin)卷(juan)(juan)厚度(du)偏(pian)差一(yi)(yi)般在0.05mm，長(chang)寬(kuan)偏(pian)差一(yi)(yi)般在5mm ，板(ban)(ban)材(cai)的(de)厚度(du)一(yi)(yi)般在0.2-3.2之間 。
