鍍(du)(du)(du)鋅是一(yi)種(zhong)經常采(cai)用(yong)(yong)的(de)經濟而有效(xiao)的(de)防腐方法。鋅產量的(de)一(yi)半左右(you)均(jun)用(yong)(yong)于此(ci)種(zhong)工藝。鍍(du)(du)(du)鋅卷(juan)(juan)是為防止鋼板(ban)表面(mian)遭受腐蝕延長(chang)(chang)其(qi)使用(yong)(yong)壽(shou)命，在(zai)(zai)鋼板(ban)表面(mian)涂(tu)以一(yi)層金屬鋅，這種(zhong)涂(tu)鋅的(de)鋼板(ban)稱為鍍(du)(du)(du)鋅卷(juan)(juan)。鍍(du)(du)(du)鋅卷(juan)(juan)主(zhu)要(yao)用(yong)(yong)于建筑、家電、汽(qi)車、容器、交通及家業(ye)等領域。特別是鋼結構建筑、汽(qi)車制(zhi)造、鋼板(ban)倉制(zhi)造等行業(ye)。耐(nai)腐蝕強、表面(mian)質量好(hao)、得利于深加工、經濟實用(yong)(yong)等。有關(guan)產品(pin)標準都列明鍍(du)(du)(du)鋅卷(juan)(juan)推薦的(de)標準厚度(du)、長(chang)(chang)度(du)和寬度(du)及其(qi)允(yun)許(xu)偏(pian)差(cha)。鍍(du)(du)(du)鋅卷(juan)(juan)厚度(du)偏(pian)差(cha)一(yi)般在(zai)(zai)0.05mm，長(chang)(chang)寬偏(pian)差(cha)一(yi)般在(zai)(zai)5mm ，板(ban)材的(de)厚度(du)一(yi)般在(zai)(zai)0.2-3.2之間 。

樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)組(zu)合板(ban)(ban)是一種(zhong)十分合理的(de)結(jie)(jie)構(gou)方式，它能(neng)夠按其各組(zu)成部件所處的(de)方位和(he)特色，充(chong)分發揮(hui)鋼(gang)材抗(kang)拉(la)和(he)混凝土抗(kang)壓(ya)功能(neng)好(hao)的(de)長處，并具有(you)杰出的(de)抗(kang)震功能(neng)、施工(gong)功能(neng)。這種(zhong)結(jie)(jie)構(gou)現(xian)在被廣泛運用于國內外修建中，但在國內大都將樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)當作(zuo)模板(ban)(ban)運用，而沒(mei)有(you)充(chong)分發揮(hui)樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)的(de)效(xiao)果。 與一般(ban)鋼(gang)筋混凝土樓(lou)板(ban)(ban)比較，樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)組(zu)合樓(lou)板(ban)(ban)具備以下長處：樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)能(neng)夠作(zuo)為現(xian)澆混凝土的(de)模板(ban)(ban)。這樣就省掉了施工(gong)中裝置和(he)撤除模板(ban)(ban)等工(gong)序(xu)，然后(hou)節約了時刻和(he)勞(lao)動力;當樓(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)裝置好(hao)今后(hou)將能(neng)夠作(zuo)為施工(gong)平臺運用。

鍍鋅(xin)鋼(gang)板(ban)(ban)(ban)是為防止鋼(gang)板(ban)(ban)(ban)表(biao)面(mian)(mian)遭受腐蝕，延長其(qi)使用壽命，在(zai)鋼(gang)板(ban)(ban)(ban)表(biao)面(mian)(mian)涂以一層金屬鋅(xin)，這(zhe)種涂鋅(xin)的(de)(de)(de)(de)薄鋼(gang)板(ban)(ban)(ban)稱(cheng)為鍍鋅(xin)板(ban)(ban)(ban)。按生產(chan)及加(jia)工方法可分為以下幾(ji)類：熱(re)浸鍍鋅(xin)鋼(gang)板(ban)(ban)(ban)。將薄鋼(gang)板(ban)(ban)(ban)浸入熔(rong) 微商貨源解的(de)(de)(de)(de)鋅(xin)槽(cao)中(zhong)，使其(qi)表(biao)面(mian)(mian)粘附一層鋅(xin)的(de)(de)(de)(de)薄鋼(gang)板(ban)(ban)(ban)。目(mu)前(qian)主要采(cai)用連(lian)續(xu)鍍鋅(xin)工藝生產(chan)，即(ji)把(ba)(ba)成(cheng)卷的(de)(de)(de)(de)鋼(gang)板(ban)(ban)(ban)連(lian)續(xu)浸在(zai)熔(rong)解有(you)鋅(xin)的(de)(de)(de)(de)鍍槽(cao)中(zhong)制成(cheng)鍍鋅(xin)鋼(gang)板(ban)(ban)(ban)；合金化(hua)鍍鋅(xin)鋼(gang)板(ban)(ban)(ban)。這(zhe)種鋼(gang)板(ban)(ban)(ban)也(ye)是用熱(re)浸法制造，但(dan)在(zai)出槽(cao)后(hou)，立即(ji)把(ba)(ba)它(ta)加(jia)熱(re)到５００℃左右，使其(qi)生成(cheng)鋅(xin)和鐵(tie)的(de)(de)(de)(de)合金被膜(mo)。這(zhe)種鍍鋅(xin)板(ban)(ban)(ban)具(ju)有(you)良好的(de)(de)(de)(de)涂料的(de)(de)(de)(de)密(mi)著性(xing)和焊接性(xing)。

由于我國鋅(xin)資源比較豐富，鍍(du)(du)鋅(xin)又(you)是(shi)一種價(jia)廉、能防銹，又(you)能裝飾的高性價(jia)比鍍(du)(du)種，因而(er)在汽(qi)(qi)車(che)(che)、機械(xie)、電(dian)(dian)子、船舶、儀表、輕工等工業(ye)部(bu)門得到(dao)廣(guang)泛的應用(yong)。如(ru)機械(xie)零件、低壓(ya)電(dian)(dian)器(qi)、高壓(ya)開關、緊固連接(jie)件、鋼鐵結構件、建筑(zhu)五金、農業(ye)機械(xie)、輕工產品等都離不開鍍(du)(du)鋅(xin)鈍化(hua)制品。鍍(du)(du)鋅(xin)板卷(juan)(juan)因此可(ke)分為(wei)熱軋鍍(du)(du)鋅(xin)板卷(juan)(juan)和冷(leng)軋熱鍍(du)(du)鋅(xin)板卷(juan)(juan)，它(ta)們主要用(yong)于建筑(zhu)、家(jia)電(dian)(dian)、汽(qi)(qi)車(che)(che)、容器(qi)、交通及家(jia)業(ye)等領域(yu)。特別是(shi)鋼結構建筑(zhu)、汽(qi)(qi)車(che)(che)制造、鋼板倉制造等行業(ye)。 重慶鍍(du)(du)鋅(xin)卷(juan)(juan)特點主要為(wei)：耐腐蝕強、表面質量好、得利于深加工、經(jing)濟實用(yong)等。

重(zhong)慶鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)按生(sheng)產及加工(gong)方法可(ke)分(fen)為以(yi)下(xia)幾(ji)類： 熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)浸入熔解的(de)(de)(de)(de)鋅(xin)(xin)(xin)(xin)槽中(zhong)，使其表面(mian)粘附一層(ceng)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)(de)薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。目前(qian)主要采用連(lian)(lian)續(xu)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)工(gong)藝生(sheng)產，即把成卷的(de)(de)(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)連(lian)(lian)續(xu)浸在熔解有鋅(xin)(xin)(xin)(xin)的(de)(de)(de)(de)鍍(du)(du)(du)槽中(zhong)制成鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)； 合金化(hua)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。為克服單(dan)面(mian)未涂(tu)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)(de)缺(que)點，又(you)有一種(zhong)在另(ling)面(mian)涂(tu)以(yi)薄(bo)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)(ban)，即雙面(mian)差(cha)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)；合金、復(fu)合鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。它是(shi)用鋅(xin)(xin)(xin)(xin)和其他(ta)金屬如(ru)鉛、鋅(xin)(xin)(xin)(xin)制成合金乃至復(fu)合鍍(du)(du)(du)成的(de)(de)(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。這種(zhong)鋼(gang)(gang)板(ban)(ban)(ban)(ban)既具有防銹性(xing)能(neng)，又(you)有良好的(de)(de)(de)(de)涂(tu)裝性(xing)能(neng)。
