熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)和(he)電鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)在鍍(du)(du)(du)鋅(xin)(xin)(xin)量(liang)上(shang)有很大(da)的差別，就像山東彩涂(tu)卷）。熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)的鍍(du)(du)(du)鋅(xin)(xin)(xin)量(liang)不(bu)可能太小(xiao)，一(yi)般(ban)較(jiao)(jiao)(jiao)(jiao)小(xiao)為雙面50～60g／m2，較(jiao)(jiao)(jiao)(jiao)大(da)可達(da)600g／m2。電鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)的鍍(du)(du)(du)鋅(xin)(xin)(xin)層可以很薄，較(jiao)(jiao)(jiao)(jiao)小(xiao)達(da)15g／m2，但要求鍍(du)(du)(du)層較(jiao)(jiao)(jiao)(jiao)厚的話則生(sheng)產線速度很慢(man)，不(bu)適應現代(dai)化機(ji)組的工藝(yi)特點，一(yi)般(ban)較(jiao)(jiao)(jiao)(jiao)大(da)為lO0g／m2左(zuo)右。正因(yin)為如此，電鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)的生(sheng)產受到(dao)很大(da)的限制。工一(yi)般(ban)電鍍(du)(du)(du)鋅(xin)(xin)(xin)比(bi)較(jiao)(jiao)(jiao)(jiao)多，適用(yong)于小(xiao)部件(jian)；熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)一(yi)般(ban)用(yong)于電力(li)設(she)備(bei)和(he)構件(jian)，適用(yong)于大(da)的部件(jian)和(he)設(she)備(bei)。當然他(ta)們(men)的價格也相對(dui)便宜一(yi)些。建設(she)部已正式(shi)下文(wen)，淘汰(tai)技術(shu)落后的冷鍍(du)(du)(du)鋅(xin)(xin)(xin)管(guan)，不(bu)準用(yong)冷鍍(du)(du)(du)鋅(xin)(xin)(xin)管(guan)作水(shui)、煤氣管(guan)。

首先，在鋼(gang)結構樓層板(ban)(ban)(ban)中(zhong)要(yao)(yao)達到耐火1.5小時(shi)，總(zong)的(de)來說可以選擇開(kai)口板(ban)(ban)(ban)、縮口板(ban)(ban)(ban)、閉口板(ban)(ban)(ban)三大(da)類。規范上混凝土要(yao)(yao)高于(yu)開(kai)口板(ban)(ban)(ban)肋(lei)頂(ding)之上80mm，并(bing)且板(ban)(ban)(ban)底需(xu)配置板(ban)(ban)(ban)底受力(li)筋(jin)。還(huan)有(you)一種就是再開(kai)口板(ban)(ban)(ban)底部刷防火涂(tu)料(liao)，涂(tu)料(liao)厚度大(da)于(yu)等于(yu)15,這樣的(de)話，只要(yao)(yao)達到構造要(yao)(yao)求(qiu)高于(yu)肋(lei)頂(ding)5公分(fen)就可以了。而縮口板(ban)(ban)(ban)和閉口板(ban)(ban)(ban)，只需(xu)要(yao)(yao)總(zong)的(de)樓板(ban)(ban)(ban)厚度大(da)于(yu)等于(yu)110即可，但是縮口板(ban)(ban)(ban)雖然在防火方面比(bi)開(kai)口板(ban)(ban)(ban)要(yao)(yao)好。但是底部還(huan)是需(xu)要(yao)(yao)加板(ban)(ban)(ban)底受力(li)筋(jin)，而閉口板(ban)(ban)(ban)則不需(xu)要(yao)(yao)。

彩涂板批發鍍鋅鋼板的表面鍍鋅主要采用的方法是熱鍍鋅。遵義彩涂板熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)是由較(jiao)古(gu)老的熱(re)鍍(du)(du)(du)(du)(du)(du)方法(fa)發(fa)展(zhan)(zhan)而來的，自從1836年法(fa)國把(ba)熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)應用(yong)于工業以來，已(yi)經有(you)一百(bai)七(qi)十年的歷史了(le)。然而，熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)工業是近(jin)三十年來伴隨冷軋帶(dai)鋼的飛速發(fa)展(zhan)(zhan)而得到了(le)大(da)規模發(fa)展(zhan)(zhan)。鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)(ye)(ye)(ye)有(you)氰(qing)(qing)化(hua)物(wu)(wu)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)和無(wu)氰(qing)(qing)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)兩(liang)類(lei)。氰(qing)(qing)化(hua)物(wu)(wu)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)中(zhong)分微氰(qing)(qing)、低氰(qing)(qing)、中(zhong)氰(qing)(qing)、和高(gao)氰(qing)(qing)幾類(lei)。無(wu)氰(qing)(qing)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)有(you)堿(jian)性鋅(xin)(xin)(xin)酸鹽鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)、銨鹽鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)、硫酸鹽鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)及無(wu)氨氯化(hua)物(wu)(wu)鍍(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)等。氰(qing)(qing)化(hua)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)(ye)(ye)(ye)均鍍(du)(du)(du)(du)(du)(du)能力好，得到的鍍(du)(du)(du)(du)(du)(du)層光(guang)滑(hua)細致，在生產中(zhong)被長期采(cai)用(yong)。但由于氰(qing)(qing)化(hua)物(wu)(wu)劇毒，對環(huan)境污染嚴(yan)重，近(jin)年來已(yi)趨向于采(cai)用(yong)低氰(qing)(qing)、微氰(qing)(qing)、無(wu)氰(qing)(qing)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)(ye)(ye)(ye)。

鍍(du)(du)鋅(xin)(xin)(xin)卷分熱鍍(du)(du)鋅(xin)(xin)(xin)和電鍍(du)(du)鋅(xin)(xin)(xin)兩種，熱鍍(du)(du)鋅(xin)(xin)(xin)鍍(du)(du)鋅(xin)(xin)(xin)層厚，具有鍍(du)(du)層均勻(yun)，附著(zhu)力(li)強，使(shi)用(yong)壽命長等(deng)(deng)優點。電鍍(du)(du)鋅(xin)(xin)(xin)成本低，表面(mian)不是(shi)很(hen)(hen)光滑，其本身的耐腐蝕性(xing)比熱鍍(du)(du)鋅(xin)(xin)(xin)管(guan)相差很(hen)(hen)多。提起鍍(du)(du)鋅(xin)(xin)(xin)管(guan)，可能沒接觸過建材的朋友并(bing)不了解。從(cong)1935年建立一條(tiao)連(lian)續涂層鋼板(ban)(ban)線開始，彩(cai)涂板(ban)(ban)得到了廣泛應用(yong)，目前彩(cai)涂板(ban)(ban)的品種繁(fan)多，大約(yue)超過600種，彩(cai)涂板(ban)(ban)兼有機聚合物(wu)與鋼板(ban)(ban)兩者的優點，既有有機聚合物(wu)的良好(hao)著(zhu)色性(xing)、成型性(xing)、耐蝕性(xing)、裝飾性(xing)、又有鋼板(ban)(ban)的高強度和易加工性(xing)，能很(hen)(hen)容易地進行沖壓裁剪、彎曲、深沖等(deng)(deng)加工。

從整體生(sheng)產(chan)(chan)方(fang)面(mian)來(lai)看(kan)，人們能夠(gou)意識到鍍鋅板在生(sheng)產(chan)(chan)過(guo)程中應(ying)用(yong)范圍(wei)是(shi)很大的(de)(de)，而各位(wei)朋(peng)(peng)友也(ye)應(ying)該認識該種產(chan)(chan)品(pin)(pin)未來(lai)發展的(de)(de)情況(kuang)，只有這(zhe)樣(yang)才(cai)能夠(gou)對產(chan)(chan)品(pin)(pin)有更為掌握(wo)。所以希望生(sheng)活中每(mei)一位(wei)朋(peng)(peng)友都能夠(gou)認知這(zhe)部分(fen)的(de)(de)內容(rong)，這(zhe)樣(yang)在每(mei)個部分(fen)才(cai)能夠(gou)獲取好的(de)(de)答案。鍍鋅板生(sheng)產(chan)(chan)方(fang)面(mian)國內存在著供(gong)應(ying)不(bu)足的(de)(de)問題，所以市(shi)場(chang)方(fang)面(mian)應(ying)該加(jia)(jia)強生(sheng)產(chan)(chan)，而在生(sheng)產(chan)(chan)技術(shu)方(fang)面(mian)的(de)(de)提(ti)升也(ye)是(shi)很重(zhong)要的(de)(de)。只有能夠(gou)以更加(jia)(jia)認真的(de)(de)態度掌握(wo)這(zhe)部分(fen)的(de)(de)內容(rong)，這(zhe)樣(yang)整體生(sheng)產(chan)(chan)才(cai)能夠(gou)更加(jia)(jia)順(shun)利。自然進口也(ye)是(shi)很重(zhong)要的(de)(de)一部分(fen)，不(bu)過(guo)進口產(chan)(chan)品(pin)(pin)在價格(ge)方(fang)面(mian)也(ye)存在著更高方(fang)面(mian)的(de)(de)問題，所以國內生(sheng)產(chan)(chan)加(jia)(jia)強是(shi)很重(zhong)要的(de)(de)。
