要看整個(ge)(ge)樓(lou)板(ban)的(de)(de)厚(hou)(hou)度(du)來考(kao)慮挑(tiao)選是(shi)(shi)用(yong)(yong)(yong)75波(bo)(bo)(bo)高(gao)系(xi)列的(de)(de)仍是(shi)(shi)51波(bo)(bo)(bo)高(gao)系(xi)列的(de)(de)，沉(chen)默有40系(xi)列，46系(xi)列，60系(xi)列，65波(bo)(bo)(bo)高(gao)系(xi)列。一般來說波(bo)(bo)(bo)高(gao)越低，承載力就越低，然(ran)后(hou)就是(shi)(shi)波(bo)(bo)(bo)峰(feng)距離越大，承載力就越小，假如整個(ge)(ge)樓(lou)板(ban)厚(hou)(hou)度(du)在(zai)10公(gong)分(fen)以(yi)內(nei)，好選用(yong)(yong)(yong)選用(yong)(yong)(yong)波(bo)(bo)(bo)高(gao)40系(xi)列，整個(ge)(ge)樓(lou)板(ban)厚(hou)(hou)度(du)在(zai)10-13公(gong)分(fen)以(yi)內(nei)，好選用(yong)(yong)(yong)50波(bo)(bo)(bo)高(gao)系(xi)列，在(zai)13公(gong)分(fen)以(yi)上(shang)，好選用(yong)(yong)(yong)75系(xi)列。有些人(ren)會(hui)問(wen)，為什么呀?其實《我國鋼筋混凝(ning)土(tu)修(xiu)建規范》里有個(ge)(ge)要求，鋼筋上(shang)面的(de)(de)混泥土(tu)保(bao)護(hu)層(ceng)不(bu)能低于2.5cm，就是(shi)(shi)說樓(lou)承板(ban)自身(shen)的(de)(de)波(bo)(bo)(bo)高(gao)+鋼筋網(wang)的(de)(de)厚(hou)(hou)度(du)(一般2cm)+2.5cm的(de)(de)保(bao)護(hu)層(ceng)≤樓(lou)板(ban)的(de)(de)厚(hou)(hou)度(du)。

蘭州冷軋卷重慶鍍鋅板按生產及加工方法可分為以下幾類： 熱浸鍍鋅鋼板。將薄鋼板浸入熔解的鋅槽中，使其表面粘附一層鋅的薄鋼板。目前主要采用連續鍍鋅工藝生產，即把成卷的鋼板連續浸在熔解有鋅的鍍槽中制成鍍鋅鋼板； 合金化鍍鋅鋼板。冷軋卷廠家為克服單面未(wei)涂(tu)鋅(xin)的缺點，又有一種在(zai)另(ling)面涂(tu)以薄層(ceng)鋅(xin)的鍍鋅(xin)板，即雙面差鍍鋅(xin)板；合(he)(he)金(jin)(jin)、復(fu)合(he)(he)鍍鋅(xin)鋼(gang)板。它是用鋅(xin)和其他金(jin)(jin)屬(shu)如鉛、鋅(xin)制成(cheng)合(he)(he)金(jin)(jin)乃(nai)至復(fu)合(he)(he)鍍成(cheng)的鋼(gang)板。這種鋼(gang)板既具有防銹性能(neng)，又有良好的涂(tu)裝性能(neng)。

鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板的(de)表面鍍(du)(du)(du)鋅(xin)(xin)(xin)主(zhu)要采(cai)(cai)用的(de)方法是(shi)熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)。熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)是(shi)由較古老的(de)熱(re)鍍(du)(du)(du)方法發(fa)展而來的(de)，自從1836年法國把熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)應用于工業以來，已經(jing)有一百(bai)七十年的(de)歷(li)史了(le)。然而，熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)工業是(shi)近三十年來伴隨冷軋帶鋼(gang)的(de)飛速發(fa)展而得到(dao)了(le)大規模發(fa)展。鍍(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)有氰(qing)(qing)(qing)(qing)化(hua)物鍍(du)(du)(du)液(ye)和(he)無(wu)氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)液(ye)兩(liang)類(lei)。氰(qing)(qing)(qing)(qing)化(hua)物鍍(du)(du)(du)液(ye)中(zhong)分微氰(qing)(qing)(qing)(qing)、低氰(qing)(qing)(qing)(qing)、中(zhong)氰(qing)(qing)(qing)(qing)、和(he)高氰(qing)(qing)(qing)(qing)幾(ji)類(lei)。無(wu)氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)液(ye)有堿性鋅(xin)(xin)(xin)酸鹽鍍(du)(du)(du)液(ye)、銨鹽鍍(du)(du)(du)液(ye)、硫酸鹽鍍(du)(du)(du)液(ye)及無(wu)氨氯化(hua)物鍍(du)(du)(du)液(ye)等。氰(qing)(qing)(qing)(qing)化(hua)鍍(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)均鍍(du)(du)(du)能力好(hao)，得到(dao)的(de)鍍(du)(du)(du)層(ceng)光滑細致，在生(sheng)產中(zhong)被長(chang)期采(cai)(cai)用。但由于氰(qing)(qing)(qing)(qing)化(hua)物劇毒，對(dui)環(huan)境污染嚴重，近年來已趨(qu)向于采(cai)(cai)用低氰(qing)(qing)(qing)(qing)、微氰(qing)(qing)(qing)(qing)、無(wu)氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)。
