鍍鋅(xin)是一(yi)種(zhong)經(jing)(jing)常采用的(de)經(jing)(jing)濟而有(you)效的(de)防(fang)腐方(fang)法。鋅(xin)產量(liang)的(de)一(yi)半左(zuo)右均用于(yu)此種(zhong)工藝。鍍鋅(xin)卷(juan)(juan)是為防(fang)止鋼(gang)(gang)板(ban)(ban)表面遭(zao)受(shou)腐蝕(shi)延(yan)長(chang)(chang)其使(shi)用壽(shou)命，在(zai)鋼(gang)(gang)板(ban)(ban)表面涂以一(yi)層金屬(shu)鋅(xin)，這種(zhong)涂鋅(xin)的(de)鋼(gang)(gang)板(ban)(ban)稱為鍍鋅(xin)卷(juan)(juan)。鍍鋅(xin)卷(juan)(juan)主要用于(yu)建(jian)筑、家(jia)電、汽(qi)車、容器、交通及家(jia)業(ye)等(deng)(deng)領(ling)域。特別(bie)是鋼(gang)(gang)結構建(jian)筑、汽(qi)車制(zhi)造、鋼(gang)(gang)板(ban)(ban)倉制(zhi)造等(deng)(deng)行(xing)業(ye)。耐腐蝕(shi)強(qiang)、表面質(zhi)量(liang)好、得利于(yu)深加(jia)工、經(jing)(jing)濟實用等(deng)(deng)。有(you)關產品標準都列明(ming)鍍鋅(xin)卷(juan)(juan)推薦的(de)標準厚度(du)、長(chang)(chang)度(du)和寬(kuan)度(du)及其允許偏差。鍍鋅(xin)卷(juan)(juan)厚度(du)偏差一(yi)般在(zai)0.05mm，長(chang)(chang)寬(kuan)偏差一(yi)般在(zai)5mm ，板(ban)(ban)材的(de)厚度(du)一(yi)般在(zai)0.2-3.2之間(jian) 。

樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)習慣主體(ti)鋼(gang)結(jie)構(gou)快速施工(gong)(gong)的(de)(de)要求，能夠(gou)在短時間內提供(gong)堅定的(de)(de)作業渠(qu)道，并可采用多個樓(lou)(lou)層(ceng)鋪設(she)壓(ya)型(xing)鋼(gang)板(ban)(ban)(ban)，分層(ceng)澆筑混凝(ning)土(tu)板(ban)(ban)(ban)的(de)(de)流水施工(gong)(gong)。在運用階段樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)作為(wei)(wei)混凝(ning)土(tu)樓(lou)(lou)板(ban)(ban)(ban)的(de)(de)受拉(la)鋼(gang)筋，也提高(gao)了樓(lou)(lou)板(ban)(ban)(ban)的(de)(de)剛度(du)(du)，節省了鋼(gang)筋和(he)混凝(ning)土(tu)的(de)(de)用量(liang)(liang)。樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)上(shang)面能夠(gou)鋪設(she)保溫，隔(ge)音(yin)，隔(ge)熱，隔(ge)振等資(zi)料。改進樓(lou)(lou)面性(xing)(xing)(xing)能充分發揮(hui)鋼(gang)的(de)(de)杰(jie)出的(de)(de)抗(kang)拉(la)強度(du)(du)和(he)延性(xing)(xing)(xing)及(ji)混凝(ning)土(tu)優良的(de)(de)抗(kang)壓(ya)強度(du)(du)和(he)較大的(de)(de)剛度(du)(du)。壓(ya)型(xing)板(ban)(ban)(ban)表面壓(ya)紋(wen)使樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)與混凝(ning)土(tu)之間產(chan)生大的(de)(de)結(jie)合力，使二者形成整體(ti)，配(pei)以加(jia)勁(jing)肋，使樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)體(ti)系(xi)具有高(gao)強承(cheng)(cheng)(cheng)載力。在懸臂條件下，樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)僅作為(wei)(wei)性(xing)(xing)(xing)模(mo)板(ban)(ban)(ban)。懸挑(tiao)的(de)(de)長度(du)(du)可根據樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)的(de)(de)截面特性(xing)(xing)(xing)來(lai)定。為(wei)(wei)了避免懸挑(tiao)板(ban)(ban)(ban)的(de)(de)開裂(lie)，需在支座處(chu)依(yi)結(jie)構(gou)工(gong)(gong)程師的(de)(de)規劃配(pei)上(shang)負筋。本公司樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)已通過國家固定救活(huo)體(ti)系(xi)及(ji)耐(nai)火構(gou)件質量(liang)(liang)檢測中心的(de)(de)耐(nai)火檢測，作為(wei)(wei)組合樓(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)無需防火噴涂，因而大大降低了工(gong)(gong)程造價(jia)。

從整(zheng)(zheng)體生(sheng)產(chan)(chan)方(fang)(fang)(fang)(fang)面(mian)來看，人們能(neng)夠意識到鍍鋅(xin)板在生(sheng)產(chan)(chan)過(guo)程中應(ying)(ying)用范圍是(shi)(shi)很大的(de)(de)(de)，而(er)各位朋友(you)也應(ying)(ying)該認識該種產(chan)(chan)品未來發展的(de)(de)(de)情況，只有這樣(yang)才(cai)能(neng)夠對產(chan)(chan)品有更為掌握。所以(yi)希(xi)望生(sheng)活(huo)中每(mei)一位朋友(you)都(dou)能(neng)夠認知(zhi)這部(bu)分(fen)的(de)(de)(de)內(nei)(nei)容，這樣(yang)在每(mei)個(ge)部(bu)分(fen)才(cai)能(neng)夠獲取好的(de)(de)(de)答案。鍍鋅(xin)板生(sheng)產(chan)(chan)方(fang)(fang)(fang)(fang)面(mian)國內(nei)(nei)存在著(zhu)供應(ying)(ying)不足的(de)(de)(de)問題，所以(yi)市場方(fang)(fang)(fang)(fang)面(mian)應(ying)(ying)該加(jia)強生(sheng)產(chan)(chan)，而(er)在生(sheng)產(chan)(chan)技(ji)術方(fang)(fang)(fang)(fang)面(mian)的(de)(de)(de)提(ti)升(sheng)也是(shi)(shi)很重要(yao)的(de)(de)(de)。只有能(neng)夠以(yi)更加(jia)認真的(de)(de)(de)態度掌握這部(bu)分(fen)的(de)(de)(de)內(nei)(nei)容，這樣(yang)整(zheng)(zheng)體生(sheng)產(chan)(chan)才(cai)能(neng)夠更加(jia)順利。自然進口(kou)也是(shi)(shi)很重要(yao)的(de)(de)(de)一部(bu)分(fen)，不過(guo)進口(kou)產(chan)(chan)品在價格方(fang)(fang)(fang)(fang)面(mian)也存在著(zhu)更高方(fang)(fang)(fang)(fang)面(mian)的(de)(de)(de)問題，所以(yi)國內(nei)(nei)生(sheng)產(chan)(chan)加(jia)強是(shi)(shi)很重要(yao)的(de)(de)(de)。

鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)是為防止鋼(gang)板(ban)(ban)(ban)(ban)表(biao)面遭受腐蝕，延長其(qi)使(shi)用(yong)壽命，在(zai)鋼(gang)板(ban)(ban)(ban)(ban)表(biao)面涂以(yi)一(yi)層金屬鋅(xin)(xin)，這(zhe)種(zhong)(zhong)涂鋅(xin)(xin)的薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)稱為鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)。按生產及(ji)加工方法(fa)可分為以(yi)下(xia)幾類：熱(re)(re)浸(jin)鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)浸(jin)入熔(rong) 微商貨源解(jie)的鋅(xin)(xin)槽(cao)(cao)中，使(shi)其(qi)表(biao)面粘附(fu)一(yi)層鋅(xin)(xin)的薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)。目前主(zhu)要采(cai)用(yong)連續鍍(du)鋅(xin)(xin)工藝生產，即(ji)把(ba)成卷的鋼(gang)板(ban)(ban)(ban)(ban)連續浸(jin)在(zai)熔(rong)解(jie)有鋅(xin)(xin)的鍍(du)槽(cao)(cao)中制成鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)；合(he)金化鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。這(zhe)種(zhong)(zhong)鋼(gang)板(ban)(ban)(ban)(ban)也是用(yong)熱(re)(re)浸(jin)法(fa)制造，但在(zai)出槽(cao)(cao)后，立(li)即(ji)把(ba)它加熱(re)(re)到(dao)５００℃左右，使(shi)其(qi)生成鋅(xin)(xin)和鐵(tie)的合(he)金被(bei)膜。這(zhe)種(zhong)(zhong)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)具有良好的涂料的密(mi)著性和焊接性。

鍍(du)(du)鋅(xin)卷(juan)分熱鍍(du)(du)鋅(xin)和電(dian)鍍(du)(du)鋅(xin)兩種，熱鍍(du)(du)鋅(xin)鍍(du)(du)鋅(xin)層厚，具有(you)鍍(du)(du)層均(jun)勻，附著(zhu)力強(qiang)(qiang)，使用壽命(ming)長等優(you)點(dian)。電(dian)鍍(du)(du)鋅(xin)成(cheng)本低，表(biao)面不是(shi)很光滑，其本身的耐腐蝕性(xing)(xing)比熱鍍(du)(du)鋅(xin)管相差(cha)很多(duo)。提起鍍(du)(du)鋅(xin)管，可能沒接觸過建材的朋友(you)并不了解(jie)。從1935年建立一條連續涂(tu)(tu)層鋼板(ban)線開始，彩涂(tu)(tu)板(ban)得到(dao)了廣泛應用，目前彩涂(tu)(tu)板(ban)的品種繁多(duo)，大約超(chao)過600種，彩涂(tu)(tu)板(ban)兼有(you)機(ji)聚合物與鋼板(ban)兩者的優(you)點(dian)，既有(you)有(you)機(ji)聚合物的良好著(zhu)色性(xing)(xing)、成(cheng)型性(xing)(xing)、耐蝕性(xing)(xing)、裝飾(shi)性(xing)(xing)、又有(you)鋼板(ban)的高強(qiang)(qiang)度(du)和易加工(gong)性(xing)(xing)，能很容易地(di)進(jin)行(xing)沖壓裁剪、彎曲、深沖等加工(gong)。

彩涂板批發鍍鋅鋼板為基板的彩涂鋼板，除有鋅保護外，鋅層上的有機涂層起了覆蓋隔離作用，可防止鋼板生銹，使用壽命比鍍鋅鋼板更長，據介紹涂層鋼板的使用壽命比鍍鋅鋼板長50%。遂寧彩涂板在(zai)連續機組上以冷軋帶鋼(gang)(gang)，鍍(du)鋅(xin)(xin)帶鋼(gang)(gang)（電鍍(du)鋅(xin)(xin)和熱鍍(du)鋅(xin)(xin)）為基板(ban)(ban)(ban)，經過(guo)表(biao)面(mian)預(yu)處(chu)理(li)(li)（脫脂和化(hua)學處(chu)理(li)(li)），用輥涂(tu)的方(fang)法，涂(tu)上一層(ceng)或(huo)多層(ceng)液態涂(tu)料(liao)，經過(guo)烘烤(kao)和冷卻(que)所得(de)的板(ban)(ban)(ban)材即(ji)為涂(tu)層(ceng)鋼(gang)(gang)板(ban)(ban)(ban)。由于(yu)涂(tu)層(ceng)可以有各種不同的顏色(se)，習(xi)慣上把涂(tu)層(ceng)鋼(gang)(gang)板(ban)(ban)(ban)叫做彩色(se)涂(tu)層(ceng)鋼(gang)(gang)板(ban)(ban)(ban)。又(you)由于(yu)涂(tu)層(ceng)是在(zai)鋼(gang)(gang)板(ban)(ban)(ban)成型加(jia)工之前(qian)進行的，在(zai)國外這(zhe)叫做預(yu)涂(tu)層(ceng)鋼(gang)(gang)板(ban)(ban)(ban)。
