鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板的表面鍍(du)(du)(du)鋅(xin)(xin)主要采(cai)用(yong)(yong)的方法(fa)是(shi)熱(re)鍍(du)(du)(du)鋅(xin)(xin)。熱(re)鍍(du)(du)(du)鋅(xin)(xin)是(shi)由較古老的熱(re)鍍(du)(du)(du)方法(fa)發展而來的，自從1836年(nian)法(fa)國把熱(re)鍍(du)(du)(du)鋅(xin)(xin)應用(yong)(yong)于工業以來，已經(jing)有一(yi)百七十年(nian)的歷史了。然(ran)而，熱(re)鍍(du)(du)(du)鋅(xin)(xin)工業是(shi)近三十年(nian)來伴隨冷軋帶鋼(gang)的飛速發展而得到了大規模(mo)發展。鍍(du)(du)(du)鋅(xin)(xin)溶(rong)(rong)液(ye)(ye)有氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)化物(wu)鍍(du)(du)(du)液(ye)(ye)和無(wu)氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)鍍(du)(du)(du)液(ye)(ye)兩類。氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)化物(wu)鍍(du)(du)(du)液(ye)(ye)中分(fen)微(wei)氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)、低氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)、中氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)、和高(gao)氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)幾類。無(wu)氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)鍍(du)(du)(du)液(ye)(ye)有堿性鋅(xin)(xin)酸(suan)鹽(yan)鍍(du)(du)(du)液(ye)(ye)、銨鹽(yan)鍍(du)(du)(du)液(ye)(ye)、硫酸(suan)鹽(yan)鍍(du)(du)(du)液(ye)(ye)及(ji)無(wu)氨氯化物(wu)鍍(du)(du)(du)液(ye)(ye)等。氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)化鍍(du)(du)(du)鋅(xin)(xin)溶(rong)(rong)液(ye)(ye)均鍍(du)(du)(du)能(neng)力好(hao)，得到的鍍(du)(du)(du)層光滑細致，在生產中被(bei)長期采(cai)用(yong)(yong)。但由于氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)化物(wu)劇毒，對環境污染嚴重(zhong)，近年(nian)來已趨向(xiang)于采(cai)用(yong)(yong)低氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)、微(wei)氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)、無(wu)氰(qing)(qing)(qing)(qing)(qing)(qing)(qing)鍍(du)(du)(du)鋅(xin)(xin)溶(rong)(rong)液(ye)(ye)。

彩(cai)(cai)(cai)鋼(gang)(gang)(gang)(gang)是(shi)(shi)指彩(cai)(cai)(cai)涂(tu)鋼(gang)(gang)(gang)(gang)板(ban)，彩(cai)(cai)(cai)涂(tu)鋼(gang)(gang)(gang)(gang)板(ban)是(shi)(shi)一種帶(dai)有(you)有(you)機涂(tu)層的(de)(de)鋼(gang)(gang)(gang)(gang)板(ban)，傳統的(de)(de)涂(tu)層分好幾類，氟碳涂(tu)層的(de)(de)，幾乎可(ke)以防腐20年。一般從鋼(gang)(gang)(gang)(gang)廠以卷筒的(de)(de)形式(shi)分銷到(dao)各地。我(wo)們經(jing)常(chang)看到(dao)的(de)(de)彩(cai)(cai)(cai)鋼(gang)(gang)(gang)(gang)板(ban)是(shi)(shi)指加工好的(de)(de)板(ban)材，厚度在50~100mm左(zuo)右，它是(shi)(shi)由中(zhong)(zhong)間的(de)(de)填料(liao)和(he)兩面的(de)(de)彩(cai)(cai)(cai)鋼(gang)(gang)(gang)(gang)板(ban)組成。其中(zhong)(zhong)，彩(cai)(cai)(cai)板(ban)厚度有(you)0.4mm、0.5mm、0.6mm等不同的(de)(de)厚度,中(zhong)(zhong)間層可(ke)以是(shi)(shi)聚(ju)胺(an)脂、巖(yan)綿或泡沫塑料(liao)等。由于有(you)專用型材，所以用彩(cai)(cai)(cai)鋼(gang)(gang)(gang)(gang)板(ban)構筑的(de)(de)廠房(fang)建(jian)造(zao)速度很快（如非典時的(de)(de)小湯山醫院），但強度低。

重慶樓承板(ban)(ban)(ban)(ban)(ban)的(de)鍍(du)(du)鋅(xin)(xin)(xin)量沒有(you)一(yi)個(ge)具體的(de)標準，制作壓(ya)型鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的(de)冷軋(ya)鋼(gang)(gang)(gang)卷須(xu)連續(xu)熱(re)(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)（或(huo)鍍(du)(du)鋁(lv)鋅(xin)(xin)(xin)），鍍(du)(du)（鋁(lv)）鋅(xin)(xin)(xin)量視設(she)計要求(qiu)而(er)定。樓承板(ban)(ban)(ban)(ban)(ban)用(yong)壓(ya)型鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)宜選擇熱(re)(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。不允許使用(yong)電鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，電鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)僅在基材(cai)表面形成保(bao)護層，防(fang)腐能力有(you)限。目前市場(chang)上有(you)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)（鍍(du)(du)層含(han)鋁(lv)5%或(huo)55%），在酸性環境下(xia)的(de)防(fang)腐效果由于(yu)熱(re)(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，但在混(hun)凝(ning)土的(de)堿性條(tiao)件下(xia)，鍍(du)(du)鋁(lv)鋅(xin)(xin)(xin)的(de)防(fang)腐蝕性能低于(yu)熱(re)(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，且鋁(lv)會和(he)混(hun)凝(ning)土發生反應，并降(jiang)低混(hun)凝(ning)土與鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)的(de)粘結性能。因此參考(kao)國(guo)外規范，及國(guo)內外工(gong)程，行家壓(ya)型鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)不建(jian)議使用(yong)鍍(du)(du)鋁(lv)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。

崇州鍍鋅鋼管重慶樓承板分兩種。一種是把樓承板當做承受拉力的鋼筋計算的，另外一種是僅把樓承板作為模板計算而不參與受力的。做模板計算的比較簡單，直接按照跨度頂就行了。2米以下選0.8的，2-3米的選1.0的。鍍鋅鋼管廠家樓承板(ban)(ban)作為受力(li)鋼筋(jin)計算(suan)，就按(an)照模板(ban)(ban)的選(xuan)用樓承板(ban)(ban)（或者加厚且只能加厚），然后(hou)在(zai)計算(suan)配筋(jin)的時(shi)候可以按(an)照面(mian)積減少(shao)鋼筋(jin)用量(liang)。樓承板(ban)(ban)不能單(dan)獨(du)計算(suan)的，它和(he)整個(ge)樓板(ban)(ban)是一個(ge)體系的。

樓(lou)承(cheng)(cheng)(cheng)板(ban)組合板(ban)是一種十分(fen)合理的(de)結構方式，它能(neng)夠(gou)(gou)(gou)按其(qi)各組成部件所處的(de)方位和(he)特色，充分(fen)發揮鋼(gang)材抗(kang)拉(la)和(he)混凝土抗(kang)壓(ya)功能(neng)好的(de)長(chang)處，并具(ju)有(you)杰出的(de)抗(kang)震功能(neng)、施工功能(neng)。這(zhe)種結構現在被廣泛運用(yong)于國(guo)內外(wai)修(xiu)建中，但在國(guo)內大都將(jiang)(jiang)樓(lou)承(cheng)(cheng)(cheng)板(ban)當作(zuo)模(mo)板(ban)運用(yong)，而沒有(you)充分(fen)發揮樓(lou)承(cheng)(cheng)(cheng)板(ban)的(de)效果。 與一般鋼(gang)筋(jin)混凝土樓(lou)板(ban)比較，樓(lou)承(cheng)(cheng)(cheng)板(ban)組合樓(lou)板(ban)具(ju)備(bei)以(yi)下長(chang)處：樓(lou)承(cheng)(cheng)(cheng)板(ban)能(neng)夠(gou)(gou)(gou)作(zuo)為(wei)現澆(jiao)混凝土的(de)模(mo)板(ban)。這(zhe)樣就(jiu)省掉了施工中裝(zhuang)置和(he)撤除模(mo)板(ban)等(deng)工序(xu)，然后節約了時刻(ke)和(he)勞(lao)動(dong)力;當樓(lou)承(cheng)(cheng)(cheng)板(ban)裝(zhuang)置好今后將(jiang)(jiang)能(neng)夠(gou)(gou)(gou)作(zuo)為(wei)施工平(ping)臺運用(yong)。
