首先，在鋼結構樓(lou)層板(ban)(ban)(ban)(ban)(ban)中要達到耐火1.5小時，總的(de)來(lai)說可(ke)以選(xuan)擇開(kai)(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)、縮口(kou)板(ban)(ban)(ban)(ban)(ban)、閉口(kou)板(ban)(ban)(ban)(ban)(ban)三大(da)類。規范上(shang)混凝土要高(gao)于(yu)開(kai)(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)肋頂之(zhi)上(shang)80mm，并(bing)且板(ban)(ban)(ban)(ban)(ban)底需(xu)配置板(ban)(ban)(ban)(ban)(ban)底受力筋(jin)。還(huan)有一種就是再開(kai)(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)底部刷防火涂(tu)料，涂(tu)料厚度(du)大(da)于(yu)等(deng)(deng)于(yu)15,這(zhe)樣的(de)話，只(zhi)要達到構造要求高(gao)于(yu)肋頂5公分就可(ke)以了(le)。而縮口(kou)板(ban)(ban)(ban)(ban)(ban)和閉口(kou)板(ban)(ban)(ban)(ban)(ban)，只(zhi)需(xu)要總的(de)樓(lou)板(ban)(ban)(ban)(ban)(ban)厚度(du)大(da)于(yu)等(deng)(deng)于(yu)110即可(ke)，但(dan)是縮口(kou)板(ban)(ban)(ban)(ban)(ban)雖(sui)然在防火方面比開(kai)(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)要好。但(dan)是底部還(huan)是需(xu)要加板(ban)(ban)(ban)(ban)(ban)底受力筋(jin)，而閉口(kou)板(ban)(ban)(ban)(ban)(ban)則不需(xu)要。

熱(re)鍍(du)鋅卷板(ban)現貨(huo)消(xiao)息：熱(re)鍍(du)鋅產(chan)(chan)品廣泛用(yong)于建(jian)筑、家電(dian)(dian)、車(che)船(chuan)、容器制造業、機電(dian)(dian)業等(deng)，幾乎涉及到衣食(shi)住行(xing)各個領域。近年(nian)來(lai)(lai)，世界鍍(du)鋅鋼板(ban)需(xu)求量不斷增加(jia)，產(chan)(chan)量增長也(ye)很(hen)快，在(zai)美、日等(deng)鋼材生產(chan)(chan)大國，熱(re)鍍(du)鋅鋼板(ban)在(zai)鋼材中所(suo)占(zhan)比(bi)例已(yi)高達13%-15%。 熱(re)鍍(du)鋅卷板(ban)現貨(huo)消(xiao)息：近來(lai)(lai)，汽車(che)行(xing)業越來(lai)(lai)越重(zhong)視材料的使用(yong)壽命(ming)，用(yong)涂(tu)漆(qi)冷軋鋼板(ban)已(yi)不能滿(man)足耐腐蝕方面的要求。在(zai)這種(zhong)情(qing)況下，耐腐蝕性(xing)優良且成(cheng)本低廉(lian)的熱(re)鍍(du)鋅板(ban)開始普遍受到了汽車(che)廠家的青睞。

我(wo)國建筑業中，噪聲污染問題久為人們(men)所詬病。輕型樓承(cheng)板(ban)(ban)的(de)(de)(de)應用使得土建建筑物局(ju)面被(bei)(bei)打破，集環境破壞及污染少、材(cai)料(liao)回收和(he)利用率高、符合可持續發展要求(qiu)(qiu)等(deng)眾(zhong)多(duo)優點于一(yi)身(shen)的(de)(de)(de)樓承(cheng)板(ban)(ban)建筑應運而生，逐步被(bei)(bei)人們(men)所接受。輕型樓承(cheng)板(ban)(ban)是近十年來發展較(jiao)快的(de)(de)(de)領域(yu)，在(zai)采用輕型樓承(cheng)板(ban)(ban)占非住宅建筑投資的(de)(de)(de)50%以上。這種(zhong)結構工(gong)業化、商品化程度高，施工(gong)快，綜合效(xiao)益高，市場需求(qiu)(qiu)量很大，已(yi)(yi)引起結構設計人員認識。樓承(cheng)板(ban)(ban)的(de)(de)(de)研究(jiu)開(kai)發已(yi)(yi)在(zai)各地試點，是輕鋼發展的(de)(de)(de)一(yi)個重要方向，目前已(yi)(yi)經有(you)多(duo)種(zhong)的(de)(de)(de)低層、多(duo)層和(he)高層的(de)(de)(de)設計方案和(he)實(shi)例。

彩涂板價格鍍鋅鋼板的表面鍍鋅主要采用的方法是熱鍍鋅。巴中彩涂板熱鍍(du)(du)(du)(du)鋅(xin)是(shi)由較古老的(de)熱鍍(du)(du)(du)(du)方法(fa)發(fa)展而(er)來(lai)的(de)，自從1836年(nian)(nian)(nian)法(fa)國(guo)把熱鍍(du)(du)(du)(du)鋅(xin)應用(yong)于工業以來(lai)，已(yi)經(jing)有(you)一百七十年(nian)(nian)(nian)的(de)歷史了。然而(er)，熱鍍(du)(du)(du)(du)鋅(xin)工業是(shi)近三十年(nian)(nian)(nian)來(lai)伴隨冷軋(ya)帶(dai)鋼的(de)飛速發(fa)展而(er)得到了大(da)規模發(fa)展。鍍(du)(du)(du)(du)鋅(xin)溶(rong)液(ye)有(you)氰(qing)(qing)(qing)(qing)(qing)(qing)化(hua)(hua)物(wu)鍍(du)(du)(du)(du)液(ye)和無氰(qing)(qing)(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)兩類。氰(qing)(qing)(qing)(qing)(qing)(qing)化(hua)(hua)物(wu)鍍(du)(du)(du)(du)液(ye)中分(fen)微氰(qing)(qing)(qing)(qing)(qing)(qing)、低氰(qing)(qing)(qing)(qing)(qing)(qing)、中氰(qing)(qing)(qing)(qing)(qing)(qing)、和高氰(qing)(qing)(qing)(qing)(qing)(qing)幾類。無氰(qing)(qing)(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)有(you)堿(jian)性(xing)鋅(xin)酸鹽鍍(du)(du)(du)(du)液(ye)、銨鹽鍍(du)(du)(du)(du)液(ye)、硫酸鹽鍍(du)(du)(du)(du)液(ye)及無氨氯化(hua)(hua)物(wu)鍍(du)(du)(du)(du)液(ye)等。氰(qing)(qing)(qing)(qing)(qing)(qing)化(hua)(hua)鍍(du)(du)(du)(du)鋅(xin)溶(rong)液(ye)均鍍(du)(du)(du)(du)能(neng)力好，得到的(de)鍍(du)(du)(du)(du)層光(guang)滑(hua)細(xi)致，在(zai)生產中被長期(qi)采用(yong)。但由于氰(qing)(qing)(qing)(qing)(qing)(qing)化(hua)(hua)物(wu)劇毒(du)，對環境污染嚴重，近年(nian)(nian)(nian)來(lai)已(yi)趨向于采用(yong)低氰(qing)(qing)(qing)(qing)(qing)(qing)、微氰(qing)(qing)(qing)(qing)(qing)(qing)、無氰(qing)(qing)(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)鋅(xin)溶(rong)液(ye)。
