重慶鍍鋅(xin)板近二(er)十年來鋼帶連續熱鍍鋅(xin)技術、裝(zhuang)(zhuang)備(bei)以(yi)(yi)及相(xiang)應的(de)控制(zhi)(zhi)手段均有(you)巨大的(de)發(fa)展，使(shi)鍍鋅(xin)板得以(yi)(yi)滿足汽車(che)面板和家電(dian)用板的(de)苛刻要求，并(bing)從而以(yi)(yi)其(qi)比電(dian)鍍鋅(xin)合金鋼帶廉價(jia)、耐蝕性優異而大有(you)取代之勢。熱鍍鋅(xin)生產技術與裝(zhuang)(zhuang)備(bei)開發(fa)技術及經(jing)驗(yan)，通(tong)過技術創新、優化設計、精密制(zhi)(zhi)造以(yi)(yi)及國(guo)外技術合作，突破制(zhi)(zhi)約我(wo)國(guo)高(gao)性能汽車(che)用熱鍍鋅(xin)鋼板生產技術與裝(zhuang)(zhuang)備(bei)發(fa)展瓶(ping)頸。

用(yong)電鍍(du)(du)(du)法制(zhi)造這種(zhong)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)具(ju)有(you)良好的(de)(de)(de)加工(gong)(gong)性(xing)。但鍍(du)(du)(du)層(ceng)較薄，耐腐蝕性(xing)不如熱(re)浸法鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)；單面(mian)(mian)(mian)鍍(du)(du)(du)和雙面(mian)(mian)(mian)差(cha)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。單面(mian)(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)，即(ji)只在(zai)(zai)一(yi)面(mian)(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)(xin)的(de)(de)(de)產品。在(zai)(zai)焊接(jie)、涂(tu)裝(zhuang)(zhuang)、防銹處理、加工(gong)(gong)等方面(mian)(mian)(mian)，具(ju)有(you)比雙面(mian)(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)好的(de)(de)(de)適應(ying)性(xing)。為克服(fu)單面(mian)(mian)(mian)未涂(tu)鋅(xin)(xin)(xin)的(de)(de)(de)缺(que)點，又有(you)一(yi)種(zhong)在(zai)(zai)另面(mian)(mian)(mian)涂(tu)以薄層(ceng)鋅(xin)(xin)(xin)的(de)(de)(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)，即(ji)雙面(mian)(mian)(mian)差(cha)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)；合(he)金、復(fu)合(he)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。它是(shi)用(yong)鋅(xin)(xin)(xin)和其他金屬如鉛、鋅(xin)(xin)(xin)制(zhi)成合(he)金乃至復(fu)合(he)鍍(du)(du)(du)成的(de)(de)(de)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。這種(zhong)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)既具(ju)有(you)防銹性(xing)能，又有(you)良好的(de)(de)(de)涂(tu)裝(zhuang)(zhuang)性(xing)能。 除(chu)上述(shu)五(wu)種(zhong)外(wai)，還有(you)彩(cai)色鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)、印花涂(tu)裝(zhuang)(zhuang)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)、聚氯乙烯疊層(ceng)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)等。但目前常用(yong)的(de)(de)(de)仍為熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)。 鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)按用(yong)途又可分(fen)為一(yi)般(ban)用(yong)、屋(wu)頂用(yong)、建筑外(wai)側板(ban)(ban)(ban)用(yong)、結(jie)構用(yong)、瓦壟(long)板(ban)(ban)(ban)用(yong)、拉伸(shen)用(yong)和深沖用(yong)等鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。

重慶鍍(du)(du)鋅(xin)板(ban)(ban)(ban)按生產及加(jia)工方法(fa)可(ke)分為以下幾類： 熱(re)浸鍍(du)(du)鋅(xin)鋼(gang)(gang)板(ban)(ban)(ban)。將薄(bo)(bo)鋼(gang)(gang)板(ban)(ban)(ban)浸入(ru)熔解(jie)的(de)(de)鋅(xin)槽(cao)中(zhong)，使其表面(mian)粘附一層(ceng)鋅(xin)的(de)(de)薄(bo)(bo)鋼(gang)(gang)板(ban)(ban)(ban)。目前主要采用(yong)連續鍍(du)(du)鋅(xin)工藝生產，即把成(cheng)卷的(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)連續浸在熔解(jie)有鋅(xin)的(de)(de)鍍(du)(du)槽(cao)中(zhong)制成(cheng)鍍(du)(du)鋅(xin)鋼(gang)(gang)板(ban)(ban)(ban)； 合金(jin)化鍍(du)(du)鋅(xin)鋼(gang)(gang)板(ban)(ban)(ban)。為克(ke)服單(dan)面(mian)未涂(tu)(tu)鋅(xin)的(de)(de)缺(que)點，又有一種在另面(mian)涂(tu)(tu)以薄(bo)(bo)層(ceng)鋅(xin)的(de)(de)鍍(du)(du)鋅(xin)板(ban)(ban)(ban)，即雙面(mian)差(cha)鍍(du)(du)鋅(xin)板(ban)(ban)(ban)；合金(jin)、復(fu)合鍍(du)(du)鋅(xin)鋼(gang)(gang)板(ban)(ban)(ban)。它(ta)是(shi)用(yong)鋅(xin)和其他金(jin)屬(shu)如鉛、鋅(xin)制成(cheng)合金(jin)乃(nai)至復(fu)合鍍(du)(du)成(cheng)的(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)。這種鋼(gang)(gang)板(ban)(ban)(ban)既具有防銹性能(neng)，又有良好的(de)(de)涂(tu)(tu)裝性能(neng)。

樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)習(xi)慣(guan)主體(ti)鋼結(jie)構(gou)(gou)快(kuai)速施工的(de)(de)要求，能(neng)夠(gou)在(zai)(zai)短時間內提(ti)供堅定的(de)(de)作(zuo)業渠道，并可采用多個樓(lou)(lou)(lou)(lou)(lou)層鋪(pu)設壓型鋼板(ban)(ban)(ban)(ban)，分(fen)層澆筑混凝土(tu)板(ban)(ban)(ban)(ban)的(de)(de)流(liu)水施工。在(zai)(zai)運用階(jie)段(duan)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)作(zuo)為(wei)混凝土(tu)樓(lou)(lou)(lou)(lou)(lou)板(ban)(ban)(ban)(ban)的(de)(de)受拉(la)鋼筋，也提(ti)高了(le)(le)樓(lou)(lou)(lou)(lou)(lou)板(ban)(ban)(ban)(ban)的(de)(de)剛度，節省(sheng)了(le)(le)鋼筋和混凝土(tu)的(de)(de)用量。樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)上面能(neng)夠(gou)鋪(pu)設保(bao)溫，隔音，隔熱，隔振(zhen)等資料。改進樓(lou)(lou)(lou)(lou)(lou)面性(xing)能(neng)充(chong)分(fen)發揮(hui)鋼的(de)(de)杰出(chu)的(de)(de)抗拉(la)強(qiang)度和延性(xing)及混凝土(tu)優良的(de)(de)抗壓強(qiang)度和較大的(de)(de)剛度。壓型板(ban)(ban)(ban)(ban)表面壓紋(wen)使(shi)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)與混凝土(tu)之間產生大的(de)(de)結(jie)合力(li)，使(shi)二者形成整(zheng)體(ti)，配以(yi)加勁肋，使(shi)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)體(ti)系(xi)具(ju)有高強(qiang)承(cheng)(cheng)(cheng)(cheng)載(zai)力(li)。在(zai)(zai)懸臂條件(jian)下，樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)僅作(zuo)為(wei)性(xing)模板(ban)(ban)(ban)(ban)。懸挑的(de)(de)長度可根據(ju)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)的(de)(de)截面特性(xing)來定。為(wei)了(le)(le)避免懸挑板(ban)(ban)(ban)(ban)的(de)(de)開裂，需在(zai)(zai)支座處依結(jie)構(gou)(gou)工程師的(de)(de)規劃配上負筋。本(ben)公司樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)已通(tong)過國家固(gu)定救活體(ti)系(xi)及耐(nai)火構(gou)(gou)件(jian)質(zhi)量檢測中心的(de)(de)耐(nai)火檢測，作(zuo)為(wei)組(zu)合樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)無需防火噴涂，因而大大降(jiang)低了(le)(le)工程造(zao)價。

鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼板的(de)表面鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)主要采(cai)用的(de)方法是熱(re)(re)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)。熱(re)(re)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)是由較古(gu)老的(de)熱(re)(re)鍍(du)(du)(du)(du)(du)方法發展而來(lai)的(de)，自從1836年(nian)(nian)法國把熱(re)(re)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)應用于工業以來(lai)，已經有(you)一百七十(shi)年(nian)(nian)的(de)歷史了。然而，熱(re)(re)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)工業是近(jin)(jin)三十(shi)年(nian)(nian)來(lai)伴隨冷軋帶鋼的(de)飛(fei)速發展而得到了大規模發展。鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)有(you)氰(qing)(qing)(qing)(qing)化物(wu)鍍(du)(du)(du)(du)(du)液(ye)和(he)無(wu)(wu)(wu)氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)(du)液(ye)兩類。氰(qing)(qing)(qing)(qing)化物(wu)鍍(du)(du)(du)(du)(du)液(ye)中分微氰(qing)(qing)(qing)(qing)、低氰(qing)(qing)(qing)(qing)、中氰(qing)(qing)(qing)(qing)、和(he)高氰(qing)(qing)(qing)(qing)幾(ji)類。無(wu)(wu)(wu)氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)(du)液(ye)有(you)堿性鋅(xin)(xin)(xin)酸(suan)鹽鍍(du)(du)(du)(du)(du)液(ye)、銨(an)鹽鍍(du)(du)(du)(du)(du)液(ye)、硫酸(suan)鹽鍍(du)(du)(du)(du)(du)液(ye)及(ji)無(wu)(wu)(wu)氨氯化物(wu)鍍(du)(du)(du)(du)(du)液(ye)等。氰(qing)(qing)(qing)(qing)化鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)均鍍(du)(du)(du)(du)(du)能力好，得到的(de)鍍(du)(du)(du)(du)(du)層光滑細致(zhi)，在生(sheng)產中被長期采(cai)用。但(dan)由于氰(qing)(qing)(qing)(qing)化物(wu)劇(ju)毒，對環境污(wu)染嚴重(zhong)，近(jin)(jin)年(nian)(nian)來(lai)已趨向于采(cai)用低氰(qing)(qing)(qing)(qing)、微氰(qing)(qing)(qing)(qing)、無(wu)(wu)(wu)氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)。

鍍鋅批發熱鍍鋅生產發展一直處于滯后狀態。20世紀50年代到60年代陸續建成了13條單張鋼板熔劑法熱鍍鋅機組，能力為10萬t/a，但因產量低、成本高、質量差、污染環境、經濟效益差等缺陷已先后停、轉產。從20世紀70年代末，我國才開始建造大型寬帶熱鍍鋅機組。崇州鍍鋅熱鍍鋅帶鋼在我國(guo)市場一直是緊(jin)缺品種。從20世紀90年代中期(qi)以來，每年都要從國(guo)外進口(kou)80-100萬t左右。隨著國(guo)內(nei)經濟的發展，尤其是汽車、家電及建筑(zhu)業的發展，對鍍鋅帶鋼的需(xu)求量也大(da)大(da)增加。
