彩涂板廠家鍍鋅鋼板的表面鍍鋅主要采用的方法是熱鍍鋅。樂山彩涂板熱(re)(re)鍍(du)(du)(du)(du)鋅(xin)是(shi)由(you)較古老的(de)熱(re)(re)鍍(du)(du)(du)(du)方法發(fa)展(zhan)而(er)(er)(er)來(lai)的(de)，自從1836年(nian)(nian)(nian)法國把(ba)熱(re)(re)鍍(du)(du)(du)(du)鋅(xin)應用于工業以來(lai)，已經有一百七十(shi)年(nian)(nian)(nian)的(de)歷史(shi)了。然而(er)(er)(er)，熱(re)(re)鍍(du)(du)(du)(du)鋅(xin)工業是(shi)近三十(shi)年(nian)(nian)(nian)來(lai)伴(ban)隨冷軋帶(dai)鋼的(de)飛速(su)發(fa)展(zhan)而(er)(er)(er)得(de)到了大規(gui)模發(fa)展(zhan)。鍍(du)(du)(du)(du)鋅(xin)溶液(ye)(ye)(ye)(ye)(ye)有氰(qing)(qing)化(hua)物(wu)鍍(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)和無氰(qing)(qing)鍍(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)兩類。氰(qing)(qing)化(hua)物(wu)鍍(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)中(zhong)分微(wei)氰(qing)(qing)、低氰(qing)(qing)、中(zhong)氰(qing)(qing)、和高氰(qing)(qing)幾類。無氰(qing)(qing)鍍(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)有堿性(xing)鋅(xin)酸鹽(yan)(yan)鍍(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)、銨鹽(yan)(yan)鍍(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)、硫(liu)酸鹽(yan)(yan)鍍(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)及無氨(an)氯化(hua)物(wu)鍍(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)等。氰(qing)(qing)化(hua)鍍(du)(du)(du)(du)鋅(xin)溶液(ye)(ye)(ye)(ye)(ye)均鍍(du)(du)(du)(du)能力好，得(de)到的(de)鍍(du)(du)(du)(du)層光滑細致，在生(sheng)產中(zhong)被長期采(cai)用。但由(you)于氰(qing)(qing)化(hua)物(wu)劇毒，對環境污染(ran)嚴重，近年(nian)(nian)(nian)來(lai)已趨向于采(cai)用低氰(qing)(qing)、微(wei)氰(qing)(qing)、無氰(qing)(qing)鍍(du)(du)(du)(du)鋅(xin)溶液(ye)(ye)(ye)(ye)(ye)。

樓(lou)(lou)承板(ban)(ban)(ban)組(zu)(zu)合(he)板(ban)(ban)(ban)是一種(zhong)十分合(he)理的(de)(de)(de)結(jie)構方(fang)式，它(ta)能(neng)(neng)夠按其各組(zu)(zu)成部件所處的(de)(de)(de)方(fang)位和特色，充(chong)分發揮鋼(gang)材抗(kang)拉(la)和混(hun)(hun)凝土抗(kang)壓功能(neng)(neng)好的(de)(de)(de)長(chang)處，并具有(you)杰出的(de)(de)(de)抗(kang)震功能(neng)(neng)、施工(gong)功能(neng)(neng)。這種(zhong)結(jie)構現在被廣(guang)泛運用(yong)于國內(nei)外修(xiu)建中，但(dan)在國內(nei)大都(dou)將樓(lou)(lou)承板(ban)(ban)(ban)當(dang)作模(mo)(mo)板(ban)(ban)(ban)運用(yong)，而沒有(you)充(chong)分發揮樓(lou)(lou)承板(ban)(ban)(ban)的(de)(de)(de)效果。 與一般(ban)鋼(gang)筋(jin)混(hun)(hun)凝土樓(lou)(lou)板(ban)(ban)(ban)比較，樓(lou)(lou)承板(ban)(ban)(ban)組(zu)(zu)合(he)樓(lou)(lou)板(ban)(ban)(ban)具備(bei)以下(xia)長(chang)處：樓(lou)(lou)承板(ban)(ban)(ban)能(neng)(neng)夠作為現澆混(hun)(hun)凝土的(de)(de)(de)模(mo)(mo)板(ban)(ban)(ban)。這樣(yang)就省掉了施工(gong)中裝置和撤除模(mo)(mo)板(ban)(ban)(ban)等工(gong)序，然后節約了時(shi)刻和勞動力;當(dang)樓(lou)(lou)承板(ban)(ban)(ban)裝置好今后將能(neng)(neng)夠作為施工(gong)平臺運用(yong)。
