我國建筑業中，噪聲污染問題久為人們所詬病。江津鍍鋅角鋼輕型樓承板的應用使得土建建筑物局面被打破，集環境破壞及污染少、材料回收和利用率高、符合可持續發展要求等眾多優點于一身的樓承板建筑應運而生，逐步被人們所接受。鍍鋅角鋼價格輕(qing)型(xing)樓(lou)承(cheng)板是近(jin)十年來(lai)發展較快的(de)(de)領域(yu)，在(zai)采用輕(qing)型(xing)樓(lou)承(cheng)板占非住(zhu)宅建筑投資的(de)(de)50%以上。這種結構工業化(hua)、商(shang)品(pin)化(hua)程度(du)高，施工快，綜合效(xiao)益高，市場需求(qiu)量很大，已引(yin)起(qi)結構設(she)計(ji)人員認(ren)識。樓(lou)承(cheng)板的(de)(de)研(yan)究開發已在(zai)各地試點，是輕(qing)鋼發展的(de)(de)一個重(zhong)要(yao)方向，目前已經有多種的(de)(de)低層、多層和高層的(de)(de)設(she)計(ji)方案和實例。

鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼板的(de)(de)表面鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)主(zhu)要采用(yong)(yong)的(de)(de)方(fang)法(fa)(fa)是熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)。熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)是由較古老的(de)(de)熱(re)鍍(du)(du)(du)(du)(du)(du)方(fang)法(fa)(fa)發展(zhan)而來(lai)的(de)(de)，自(zi)從1836年(nian)(nian)法(fa)(fa)國把熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)應(ying)用(yong)(yong)于(yu)工(gong)業(ye)以(yi)來(lai)，已經(jing)有(you)(you)一百(bai)七十年(nian)(nian)的(de)(de)歷史了。然而，熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)工(gong)業(ye)是近(jin)三十年(nian)(nian)來(lai)伴隨冷軋(ya)帶鋼的(de)(de)飛速發展(zhan)而得(de)到了大規模發展(zhan)。鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)有(you)(you)氰化(hua)物鍍(du)(du)(du)(du)(du)(du)液(ye)和無(wu)氰鍍(du)(du)(du)(du)(du)(du)液(ye)兩類(lei)。氰化(hua)物鍍(du)(du)(du)(du)(du)(du)液(ye)中分微氰、低氰、中氰、和高氰幾類(lei)。無(wu)氰鍍(du)(du)(du)(du)(du)(du)液(ye)有(you)(you)堿性(xing)鋅(xin)(xin)(xin)酸(suan)鹽鍍(du)(du)(du)(du)(du)(du)液(ye)、銨鹽鍍(du)(du)(du)(du)(du)(du)液(ye)、硫酸(suan)鹽鍍(du)(du)(du)(du)(du)(du)液(ye)及無(wu)氨氯(lv)化(hua)物鍍(du)(du)(du)(du)(du)(du)液(ye)等。氰化(hua)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)均鍍(du)(du)(du)(du)(du)(du)能力好，得(de)到的(de)(de)鍍(du)(du)(du)(du)(du)(du)層(ceng)光滑細(xi)致，在生產中被(bei)長期采用(yong)(yong)。但由于(yu)氰化(hua)物劇毒，對環境污染嚴重，近(jin)年(nian)(nian)來(lai)已趨向(xiang)于(yu)采用(yong)(yong)低氰、微氰、無(wu)氰鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)液(ye)。
