鍍鋅角鋼廠家鍍鋅鋼板的表面鍍鋅主要采用的方法是熱鍍鋅。寶山鍍鋅角鋼熱鍍(du)鋅(xin)(xin)是由較(jiao)古(gu)老的熱鍍(du)方法(fa)發(fa)展(zhan)而(er)來(lai)的，自從1836年(nian)法(fa)國把熱鍍(du)鋅(xin)(xin)應用(yong)于工(gong)業(ye)以來(lai)，已經(jing)有一百七十(shi)(shi)年(nian)的歷史(shi)了(le)。然而(er)，熱鍍(du)鋅(xin)(xin)工(gong)業(ye)是近三(san)十(shi)(shi)年(nian)來(lai)伴隨(sui)冷軋(ya)帶鋼的飛(fei)速發(fa)展(zhan)而(er)得到(dao)了(le)大規模發(fa)展(zhan)。鍍(du)鋅(xin)(xin)溶液(ye)(ye)有氰(qing)(qing)(qing)化(hua)物(wu)鍍(du)液(ye)(ye)和無氰(qing)(qing)(qing)鍍(du)液(ye)(ye)兩類。氰(qing)(qing)(qing)化(hua)物(wu)鍍(du)液(ye)(ye)中(zhong)分微(wei)氰(qing)(qing)(qing)、低氰(qing)(qing)(qing)、中(zhong)氰(qing)(qing)(qing)、和高氰(qing)(qing)(qing)幾類。無氰(qing)(qing)(qing)鍍(du)液(ye)(ye)有堿性鋅(xin)(xin)酸鹽鍍(du)液(ye)(ye)、銨鹽鍍(du)液(ye)(ye)、硫酸鹽鍍(du)液(ye)(ye)及無氨氯化(hua)物(wu)鍍(du)液(ye)(ye)等(deng)。氰(qing)(qing)(qing)化(hua)鍍(du)鋅(xin)(xin)溶液(ye)(ye)均鍍(du)能(neng)力好，得到(dao)的鍍(du)層光滑細致，在生(sheng)產中(zhong)被長期采(cai)用(yong)。但(dan)由于氰(qing)(qing)(qing)化(hua)物(wu)劇毒，對環境污染(ran)嚴重，近年(nian)來(lai)已趨(qu)向(xiang)于采(cai)用(yong)低氰(qing)(qing)(qing)、微(wei)氰(qing)(qing)(qing)、無氰(qing)(qing)(qing)鍍(du)鋅(xin)(xin)溶液(ye)(ye)。

重慶樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)分兩種。一種是把樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)當做(zuo)承(cheng)(cheng)(cheng)受拉(la)力的(de)鋼筋(jin)計(ji)(ji)算(suan)(suan)的(de)，另外一種是僅把樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)作為模(mo)板(ban)(ban)(ban)計(ji)(ji)算(suan)(suan)而不(bu)參(can)與受力的(de)。做(zuo)模(mo)板(ban)(ban)(ban)計(ji)(ji)算(suan)(suan)的(de)比較(jiao)簡(jian)單，直接(jie)按(an)照跨度頂就行了。2米以下選0.8的(de)，2-3米的(de)選1.0的(de)。樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)作為受力鋼筋(jin)計(ji)(ji)算(suan)(suan)，就按(an)照模(mo)板(ban)(ban)(ban)的(de)選用樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)（或者加厚(hou)且只(zhi)能(neng)加厚(hou)），然后在計(ji)(ji)算(suan)(suan)配筋(jin)的(de)時(shi)候可以按(an)照面(mian)積減(jian)少鋼筋(jin)用量。樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)不(bu)能(neng)單獨計(ji)(ji)算(suan)(suan)的(de)，它和整個樓(lou)板(ban)(ban)(ban)是一個體系(xi)的(de)。
