我國建筑(zhu)(zhu)業(ye)中，噪(zao)聲污(wu)染問題久為(wei)人(ren)們所詬(gou)病。輕型(xing)樓(lou)承(cheng)(cheng)板的(de)(de)應(ying)用使(shi)得(de)土建建筑(zhu)(zhu)物局面被打破，集環境破壞及(ji)污(wu)染少、材料回收和利用率高(gao)、符合可(ke)持續發(fa)展(zhan)要求等(deng)眾多(duo)優點于一身的(de)(de)樓(lou)承(cheng)(cheng)板建筑(zhu)(zhu)應(ying)運(yun)而生(sheng)，逐步被人(ren)們所接受。輕型(xing)樓(lou)承(cheng)(cheng)板是近十年來發(fa)展(zhan)較快的(de)(de)領域，在(zai)采用輕型(xing)樓(lou)承(cheng)(cheng)板占非(fei)住宅建筑(zhu)(zhu)投資的(de)(de)50%以(yi)上。這種結(jie)構工業(ye)化(hua)、商(shang)品化(hua)程度(du)高(gao)，施工快，綜合效益高(gao)，市場需求量很大，已引起結(jie)構設計(ji)人(ren)員(yuan)認識。樓(lou)承(cheng)(cheng)板的(de)(de)研究(jiu)開發(fa)已在(zai)各地試點，是輕鋼發(fa)展(zhan)的(de)(de)一個重要方向，目前(qian)已經有多(duo)種的(de)(de)低(di)層(ceng)、多(duo)層(ceng)和高(gao)層(ceng)的(de)(de)設計(ji)方案和實(shi)例。

鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)按(an)用(yong)(yong)(yong)(yong)途(tu)又可分(fen)為(wei)一(yi)般(ban)(ban)用(yong)(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)(yong)、建筑(zhu)外側(ce)板(ban)用(yong)(yong)(yong)(yong)、結構(gou)用(yong)(yong)(yong)(yong)、瓦(wa)壟板(ban)用(yong)(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)(yong)和(he)深沖用(yong)(yong)(yong)(yong)等(deng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)。對于一(yi)般(ban)(ban)防(fang)(fang)保護(hu)(hu)(hu)用(yong)(yong)(yong)(yong)鍍(du)(du)層，可以(yi)(yi)采用(yong)(yong)(yong)(yong)堿性(xing)鋅(xin)(xin)(xin)(xin)酸鹽鍍(du)(du)鋅(xin)(xin)(xin)(xin)彩色鈍化(hua)工(gong)藝。有時為(wei)了產品的(de)(de)(de)配色需要，也可以(yi)(yi)采用(yong)(yong)(yong)(yong)藍白色鈍化(hua)工(gong)藝，比如軍(jun)綠(lv)色鈍化(hua)、黑色鈍化(hua)等(deng)。為(wei)提高鋼(gang)(gang)(gang)(gang)管(guan)(guan)的(de)(de)(de)耐(nai)腐(fu)(fu)蝕性(xing)能，對一(yi)般(ban)(ban)鋼(gang)(gang)(gang)(gang)管(guan)(guan)進行鍍(du)(du)鋅(xin)(xin)(xin)(xin)。鍍(du)(du)鋅(xin)(xin)(xin)(xin)卷分(fen)熱鍍(du)(du)鋅(xin)(xin)(xin)(xin)和(he)電(dian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)兩(liang)種，熱鍍(du)(du)鋅(xin)(xin)(xin)(xin)鍍(du)(du)鋅(xin)(xin)(xin)(xin)層厚，電(dian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)成(cheng)本低，表(biao)面不是很光滑(hua)。吹氧(yang)焊管(guan)(guan)：用(yong)(yong)(yong)(yong)作煉鋼(gang)(gang)(gang)(gang)吹氧(yang)用(yong)(yong)(yong)(yong)管(guan)(guan)，一(yi)般(ban)(ban)用(yong)(yong)(yong)(yong)小口徑的(de)(de)(de)焊接鋼(gang)(gang)(gang)(gang)管(guan)(guan)，規格(ge)由(you)(you)3/8-2寸八種。用(yong)(yong)(yong)(yong)08、10、15、20或(huo)者195-Q235的(de)(de)(de)鋼(gang)(gang)(gang)(gang)帶制作成(cheng)的(de)(de)(de)，為(wei)了防(fang)(fang)腐(fu)(fu)蝕，有得進行滲鋁處(chu)理(li)。鍍(du)(du)鋅(xin)(xin)(xin)(xin)其防(fang)(fang)護(hu)(hu)(hu)作用(yong)(yong)(yong)(yong)更(geng)強(qiang)(qiang)(qiang)，抗腐(fu)(fu)蝕能力強(qiang)(qiang)(qiang)。整個結構(gou)由(you)(you)鋅(xin)(xin)(xin)(xin)，形成(cheng)致密的(de)(de)(de)四元(yuan)結晶(jing)體，此結晶(jing)體在鋼(gang)(gang)(gang)(gang)板(ban)上形成(cheng)一(yi)層屏(ping)障， 因而有效的(de)(de)(de)防(fang)(fang)止腐(fu)(fu)蝕因子(zi)穿透。 耐(nai)腐(fu)(fu)蝕性(xing)來自鋅(xin)(xin)(xin)(xin)的(de)(de)(de)障礙層保護(hu)(hu)(hu)功能強(qiang)(qiang)(qiang)。

首先，在鋼結構樓層板中要達到耐火1.5小時，總的來說可以選擇開口板、縮口板、閉口板三大類。廣安鍍鋅卷規范上混凝土要高于開口板肋頂之上80mm，并且板底需配置板底受力筋。還有一種就是再開口板底部刷防火涂料，涂料厚度大于等于15,這樣的話，只要達到構造要求高于肋頂5公分就可以了。鍍鋅卷價格而(er)縮口(kou)板(ban)(ban)(ban)(ban)和(he)閉(bi)口(kou)板(ban)(ban)(ban)(ban)，只需要總的樓板(ban)(ban)(ban)(ban)厚度(du)大于等(deng)于110即(ji)可(ke)，但是(shi)(shi)縮口(kou)板(ban)(ban)(ban)(ban)雖(sui)然在(zai)防(fang)火(huo)方面比開(kai)口(kou)板(ban)(ban)(ban)(ban)要好。但是(shi)(shi)底(di)部(bu)還是(shi)(shi)需要加板(ban)(ban)(ban)(ban)底(di)受力筋，而(er)閉(bi)口(kou)板(ban)(ban)(ban)(ban)則(ze)不需要。

由(you)于我國(guo)鋅(xin)資源(yuan)比較豐(feng)富(fu)，鍍(du)(du)鋅(xin)又是一(yi)種價廉、能(neng)防銹(xiu)，又能(neng)裝飾(shi)的高性價比鍍(du)(du)種，因而在汽車(che)、機械、電子、船(chuan)舶、儀表、輕工等(deng)(deng)工業(ye)(ye)(ye)部門(men)得(de)到廣(guang)泛的應用。如機械零件(jian)、低(di)壓電器(qi)(qi)、高壓開關、緊固連(lian)接件(jian)、鋼(gang)鐵結(jie)構(gou)件(jian)、建筑五金、農業(ye)(ye)(ye)機械、輕工產(chan)品等(deng)(deng)都離不開鍍(du)(du)鋅(xin)鈍化制(zhi)品。鍍(du)(du)鋅(xin)板(ban)卷因此可分為(wei)熱軋(ya)鍍(du)(du)鋅(xin)板(ban)卷和冷(leng)軋(ya)熱鍍(du)(du)鋅(xin)板(ban)卷，它們主(zhu)(zhu)要用于建筑、家(jia)電、汽車(che)、容(rong)器(qi)(qi)、交通(tong)及家(jia)業(ye)(ye)(ye)等(deng)(deng)領域(yu)。特別是鋼(gang)結(jie)構(gou)建筑、汽車(che)制(zhi)造(zao)、鋼(gang)板(ban)倉制(zhi)造(zao)等(deng)(deng)行業(ye)(ye)(ye)。 重慶鍍(du)(du)鋅(xin)卷特點主(zhu)(zhu)要為(wei)：耐(nai)腐蝕強、表面質(zhi)量(liang)好、得(de)利于深加工、經濟實(shi)用等(deng)(deng)。
