鍍(du)(du)鋅(xin)(xin)(xin)(xin)是一(yi)種(zhong)經(jing)常采用(yong)的(de)(de)經(jing)濟而有效的(de)(de)防(fang)腐方法(fa)。鋅(xin)(xin)(xin)(xin)產量(liang)的(de)(de)一(yi)半左右均用(yong)于此種(zhong)工藝。鍍(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)是為(wei)防(fang)止鋼板(ban)(ban)(ban)表面遭(zao)受腐蝕延(yan)長其使用(yong)壽命，在鋼板(ban)(ban)(ban)表面涂(tu)(tu)以一(yi)層金屬鋅(xin)(xin)(xin)(xin)，這種(zhong)涂(tu)(tu)鋅(xin)(xin)(xin)(xin)的(de)(de)鋼板(ban)(ban)(ban)稱為(wei)鍍(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)。鍍(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)主要用(yong)于建筑、家電、汽車、容器、交通(tong)及家業等領域。特別(bie)是鋼結構建筑、汽車制造、鋼板(ban)(ban)(ban)倉制造等行業。耐腐蝕強、表面質(zhi)量(liang)好、得利于深加工、經(jing)濟實(shi)用(yong)等。有關產品標準(zhun)都列明鍍(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)推薦(jian)的(de)(de)標準(zhun)厚(hou)度、長度和(he)寬(kuan)度及其允許偏差(cha)。鍍(du)(du)鋅(xin)(xin)(xin)(xin)卷(juan)厚(hou)度偏差(cha)一(yi)般在0.05mm，長寬(kuan)偏差(cha)一(yi)般在5mm ，板(ban)(ban)(ban)材的(de)(de)厚(hou)度一(yi)般在0.2-3.2之間 。

用電鍍法制造這種鍍鋅鋼板具有良好的加工性。但鍍層較薄，耐腐蝕性不如熱浸法鍍鋅板；單面鍍和雙面差鍍鋅鋼板。單面鍍鋅鋼板，即只在一面鍍鋅的產品。城口鍍鋅在焊接、涂裝、防銹處理、加工等方面，具有比雙面鍍鋅板好的適應性。為克服單面未涂鋅的缺點，又有一種在另面涂以薄層鋅的鍍鋅板，即雙面差鍍鋅板；合金、復合鍍鋅鋼板。鍍鋅廠家它是用(yong)鋅(xin)(xin)(xin)(xin)和(he)其他(ta)金屬(shu)如(ru)鉛(qian)、鋅(xin)(xin)(xin)(xin)制成(cheng)合金乃(nai)至復合鍍成(cheng)的(de)鋼板(ban)。這種(zhong)鋼板(ban)既(ji)具(ju)有(you)防銹性能，又(you)有(you)良(liang)好(hao)的(de)涂裝性能。 除(chu)上(shang)述(shu)五種(zhong)外，還有(you)彩色鍍鋅(xin)(xin)(xin)(xin)鋼板(ban)、印(yin)花涂裝鍍鋅(xin)(xin)(xin)(xin)鋼板(ban)、聚氯乙烯疊層鍍鋅(xin)(xin)(xin)(xin)鋼板(ban)等。但目前常用(yong)的(de)仍(reng)為熱浸鍍鋅(xin)(xin)(xin)(xin)板(ban)。 鍍鋅(xin)(xin)(xin)(xin)鋼板(ban)按用(yong)途又(you)可分為一(yi)般用(yong)、屋頂用(yong)、建筑外側(ce)板(ban)用(yong)、結構用(yong)、瓦壟板(ban)用(yong)、拉伸(shen)用(yong)和(he)深(shen)沖用(yong)等鍍鋅(xin)(xin)(xin)(xin)鋼板(ban)。

鍍鋅板使(shi)(shi)用(yong)(yong)的(de)(de)時候，自(zi)(zi)(zi)然也是(shi)要讓(rang)它(ta)(ta)(ta)在(zai)(zai)質(zhi)量上(shang)面(mian)(mian)(mian)達(da)到很(hen)(hen)好(hao)的(de)(de)表(biao)現(xian)(xian)(xian)(xian)，但是(shi)對(dui)于(yu)它(ta)(ta)(ta)在(zai)(zai)自(zi)(zi)(zi)己(ji)(ji)的(de)(de)質(zhi)量表(biao)現(xian)(xian)(xian)(xian)表(biao)現(xian)(xian)(xian)(xian)來說(shuo)，往(wang)往(wang)是(shi)有(you)很(hen)(hen)多(duo)方面(mian)(mian)(mian)的(de)(de)，那么它(ta)(ta)(ta)在(zai)(zai)自(zi)(zi)(zi)己(ji)(ji)的(de)(de)質(zhi)量上(shang)面(mian)(mian)(mian)都是(shi)有(you)什么表(biao)現(xian)(xian)(xian)(xian)呢(ni)？首先一(yi)個(ge)(ge)方面(mian)(mian)(mian)，就(jiu)是(shi)它(ta)(ta)(ta)在(zai)(zai)自(zi)(zi)(zi)己(ji)(ji)的(de)(de)表(biao)面(mian)(mian)(mian)上(shang)要達(da)到平的(de)(de)要求，這一(yi)點(dian)自(zi)(zi)(zi)然也是(shi)它(ta)(ta)(ta)在(zai)(zai)自(zi)(zi)(zi)己(ji)(ji)使(shi)(shi)用(yong)(yong)時的(de)(de)一(yi)個(ge)(ge)重要的(de)(de)表(biao)現(xian)(xian)(xian)(xian)，現(xian)(xian)(xian)(xian)在(zai)(zai)也一(yi)些廠家，他們在(zai)(zai)生產(chan)時，因(yin)為沒(mei)有(you)使(shi)(shi)用(yong)(yong)很(hen)(hen)好(hao)的(de)(de)設備，也或(huo)者是(shi)在(zai)(zai)技術上(shang)面(mian)(mian)(mian)低下，自(zi)(zi)(zi)然就(jiu)沒(mei)有(you)這方面(mian)(mian)(mian)的(de)(de)表(biao)現(xian)(xian)(xian)(xian)。重慶鍍鋅板本身的(de)(de)性能上(shang)面(mian)(mian)(mian)有(you)很(hen)(hen)大(da)的(de)(de)下降，而(er)且因(yin)為它(ta)(ta)(ta)在(zai)(zai)自(zi)(zi)(zi)己(ji)(ji)的(de)(de)平上(shang)面(mian)(mian)(mian)沒(mei)有(you)自(zi)(zi)(zi)己(ji)(ji)的(de)(de)表(biao)現(xian)(xian)(xian)(xian)，同(tong)時用(yong)(yong)戶在(zai)(zai)自(zi)(zi)(zi)己(ji)(ji)使(shi)(shi)用(yong)(yong)時，也不(bu)會達(da)到很(hen)(hen)高的(de)(de)使(shi)(shi)用(yong)(yong)壽命。

樓承板(ban)(ban)的(de)(de)使(shi)用是需(xu)(xu)要(yao)安裝的(de)(de)，那么如果要(yao)安裝就要(yao)選擇合適的(de)(de)小配件，焊(han)后(hou)栓釘高(gao)度(du)大于(yu)(yu)(yu)壓型鋼(gang)板(ban)(ban)波高(gao)30MM(留(liu)(liu)意挑(tiao)選樓板(ban)(ban)的(de)(de)類型);栓釘頂面混凝(ning)土(tu)保護層(ceng)不小于(yu)(yu)(yu)15MM(留(liu)(liu)意樓板(ban)(ban)總(zong)厚度(du))直徑(jing)不宜大于(yu)(yu)(yu)19MM。樓承板(ban)(ban)栓釘類型有ф8、ф10、ф13、ф16、ф19、ф22、ф25，栓釘一般在(zai)(zai)鋼(gang)結(jie)構修建中(zhong)(zhong),遍及使(shi)用在(zai)(zai)柱(zhu)腳(jiao)和樓板(ban)(ban)中(zhong)(zhong),一般剛度(du)要(yao)求高(gao)的(de)(de)柱(zhu)腳(jiao)都選用鋼(gang)柱(zhu)內(nei)伸至混凝(ning)土(tu)中(zhong)(zhong)，鋼(gang)柱(zhu)埋入混凝(ning)土(tu)的(de)(de)部位四(si)周(zhou)均布(bu)栓釘。樓承板(ban)(ban)輕(qing)鋼(gang)結(jie)構常(chang)用厚度(du)為0.8mm,1.0mm，1.2mm,荷載(zai)較(jiao)大的(de)(de)情況下會(hui)用到1.5mm。一般需(xu)(xu)要(yao)用栓釘與鋼(gang)梁銜接，板(ban)(ban)中(zhong)(zhong)配少量鋼(gang)筋，上面澆混凝(ning)土(tu)層(ceng)，總(zong)厚度(du)約在(zai)(zai)100-200mm之間。

鍍(du)(du)(du)鋅(xin)鋼(gang)板的(de)(de)表(biao)面鍍(du)(du)(du)鋅(xin)主要采用(yong)的(de)(de)方法是熱(re)(re)鍍(du)(du)(du)鋅(xin)。熱(re)(re)鍍(du)(du)(du)鋅(xin)是由較古(gu)老(lao)的(de)(de)熱(re)(re)鍍(du)(du)(du)方法發(fa)展(zhan)而來(lai)的(de)(de)，自從1836年(nian)(nian)法國(guo)把熱(re)(re)鍍(du)(du)(du)鋅(xin)應用(yong)于工業以來(lai)，已經有一百七(qi)十年(nian)(nian)的(de)(de)歷(li)史了。然而，熱(re)(re)鍍(du)(du)(du)鋅(xin)工業是近三十年(nian)(nian)來(lai)伴隨冷軋帶鋼(gang)的(de)(de)飛速(su)發(fa)展(zhan)而得到(dao)了大規模發(fa)展(zhan)。鍍(du)(du)(du)鋅(xin)溶(rong)液(ye)(ye)(ye)有氰(qing)(qing)化(hua)(hua)物(wu)(wu)(wu)鍍(du)(du)(du)液(ye)(ye)(ye)和(he)(he)無(wu)氰(qing)(qing)鍍(du)(du)(du)液(ye)(ye)(ye)兩類。氰(qing)(qing)化(hua)(hua)物(wu)(wu)(wu)鍍(du)(du)(du)液(ye)(ye)(ye)中分微氰(qing)(qing)、低氰(qing)(qing)、中氰(qing)(qing)、和(he)(he)高氰(qing)(qing)幾類。無(wu)氰(qing)(qing)鍍(du)(du)(du)液(ye)(ye)(ye)有堿性(xing)鋅(xin)酸鹽(yan)(yan)鍍(du)(du)(du)液(ye)(ye)(ye)、銨鹽(yan)(yan)鍍(du)(du)(du)液(ye)(ye)(ye)、硫(liu)酸鹽(yan)(yan)鍍(du)(du)(du)液(ye)(ye)(ye)及無(wu)氨氯化(hua)(hua)物(wu)(wu)(wu)鍍(du)(du)(du)液(ye)(ye)(ye)等。氰(qing)(qing)化(hua)(hua)鍍(du)(du)(du)鋅(xin)溶(rong)液(ye)(ye)(ye)均鍍(du)(du)(du)能力好，得到(dao)的(de)(de)鍍(du)(du)(du)層光(guang)滑細致，在生產(chan)中被長期(qi)采用(yong)。但由于氰(qing)(qing)化(hua)(hua)物(wu)(wu)(wu)劇毒，對環境污(wu)染嚴(yan)重，近年(nian)(nian)來(lai)已趨向于采用(yong)低氰(qing)(qing)、微氰(qing)(qing)、無(wu)氰(qing)(qing)鍍(du)(du)(du)鋅(xin)溶(rong)液(ye)(ye)(ye)。
