我(wo)國建(jian)(jian)筑(zhu)業(ye)中，噪(zao)聲(sheng)污染問題久為人(ren)們所詬(gou)病。輕(qing)型(xing)(xing)樓(lou)承(cheng)(cheng)(cheng)板的(de)應(ying)用(yong)使(shi)得(de)土建(jian)(jian)建(jian)(jian)筑(zhu)物(wu)局面(mian)被打破，集環境(jing)破壞及污染少、材料回收和利用(yong)率高(gao)、符合可持續(xu)發(fa)展(zhan)要(yao)求等(deng)眾(zhong)多(duo)優點于一(yi)身的(de)樓(lou)承(cheng)(cheng)(cheng)板建(jian)(jian)筑(zhu)應(ying)運而生(sheng)，逐步被人(ren)們所接受。輕(qing)型(xing)(xing)樓(lou)承(cheng)(cheng)(cheng)板是近十年來發(fa)展(zhan)較快的(de)領域，在(zai)采用(yong)輕(qing)型(xing)(xing)樓(lou)承(cheng)(cheng)(cheng)板占非住(zhu)宅(zhai)建(jian)(jian)筑(zhu)投資的(de)50%以上。這種結構工業(ye)化(hua)、商品化(hua)程度高(gao)，施工快，綜(zong)合效益高(gao)，市場需求量很大，已引起(qi)結構設計人(ren)員(yuan)認識。樓(lou)承(cheng)(cheng)(cheng)板的(de)研(yan)究開(kai)發(fa)已在(zai)各地試點，是輕(qing)鋼發(fa)展(zhan)的(de)一(yi)個重要(yao)方向(xiang)，目前已經有多(duo)種的(de)低層、多(duo)層和高(gao)層的(de)設計方案和實(shi)例。

由于我國鋅(xin)資源比較豐富，鍍(du)(du)鋅(xin)又是(shi)一種價(jia)(jia)廉、能防銹，又能裝飾(shi)的高性價(jia)(jia)比鍍(du)(du)種，因而在汽(qi)車、機(ji)械、電子、船舶、儀表、輕工等(deng)工業(ye)(ye)部門得到(dao)廣(guang)泛的應用。如機(ji)械零件、低壓電器、高壓開(kai)關、緊固連接件、鋼鐵結構件、建筑五(wu)金、農業(ye)(ye)機(ji)械、輕工產品(pin)等(deng)都(dou)離不開(kai)鍍(du)(du)鋅(xin)鈍化(hua)制品(pin)。鍍(du)(du)鋅(xin)板卷因此可分(fen)為(wei)熱軋(ya)鍍(du)(du)鋅(xin)板卷和冷軋(ya)熱鍍(du)(du)鋅(xin)板卷，它們主要用于建筑、家電、汽(qi)車、容(rong)器、交通及(ji)家業(ye)(ye)等(deng)領域。特(te)別是(shi)鋼結構建筑、汽(qi)車制造、鋼板倉制造等(deng)行業(ye)(ye)。 重慶鍍(du)(du)鋅(xin)卷特(te)點主要為(wei)：耐腐蝕強、表面質(zhi)量好、得利于深(shen)加工、經濟實用等(deng)。

鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)是(shi)(shi)為(wei)防(fang)止鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面遭受(shou)腐蝕，延長(chang)其(qi)使用(yong)壽命(ming)，在鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面涂以一層金(jin)(jin)屬(shu)鋅(xin)(xin)(xin)(xin)，這(zhe)種涂鋅(xin)(xin)(xin)(xin)的(de)(de)(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)稱為(wei)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)。鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)也是(shi)(shi)用(yong)熱浸(jin)(jin)法制(zhi)造(zao)，但(dan)在出(chu)槽后(hou)，立(li)即把(ba)(ba)它(ta)(ta)加熱到500℃左右，使其(qi)生(sheng)(sheng)成(cheng)(cheng)鋅(xin)(xin)(xin)(xin)和鐵(tie)的(de)(de)(de)合(he)金(jin)(jin)被膜。這(zhe)種鍍(du)(du)鋅(xin)(xin)(xin)(xin)卷具(ju)有良(liang)(liang)好的(de)(de)(de)涂料的(de)(de)(de)密著(zhu)性(xing)和焊接性(xing)。合(he)金(jin)(jin)化鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)也是(shi)(shi)用(yong)熱浸(jin)(jin)法制(zhi)造(zao)，但(dan)在出(chu)槽后(hou)，立(li)即把(ba)(ba)它(ta)(ta)加熱到500℃左右，使其(qi)生(sheng)(sheng)成(cheng)(cheng)鋅(xin)(xin)(xin)(xin)和鐵(tie)的(de)(de)(de)合(he)金(jin)(jin)被膜。這(zhe)種鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)具(ju)有良(liang)(liang)好的(de)(de)(de)涂料的(de)(de)(de)密著(zhu)性(xing)和焊接性(xing)。熱浸(jin)(jin)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)浸(jin)(jin)入(ru)熔解的(de)(de)(de)鋅(xin)(xin)(xin)(xin)槽中，使其(qi)表(biao)面粘附一層鋅(xin)(xin)(xin)(xin)的(de)(de)(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。目前(qian)主要采用(yong)連續鍍(du)(du)鋅(xin)(xin)(xin)(xin)工藝生(sheng)(sheng)產，即把(ba)(ba)成(cheng)(cheng)卷的(de)(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)連續浸(jin)(jin)在熔解有鋅(xin)(xin)(xin)(xin)的(de)(de)(de)鍍(du)(du)槽中制(zhi)成(cheng)(cheng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。合(he)金(jin)(jin)、復合(he)鍍(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。它(ta)(ta)是(shi)(shi)用(yong)鋅(xin)(xin)(xin)(xin)和其(qi)他金(jin)(jin)屬(shu)如鉛、鋅(xin)(xin)(xin)(xin)制(zhi)成(cheng)(cheng)合(he)金(jin)(jin)乃至復合(he)鍍(du)(du)成(cheng)(cheng)的(de)(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)既(ji)具(ju)有防(fang)銹性(xing)能，又有良(liang)(liang)好的(de)(de)(de)涂裝(zhuang)性(xing)能。

蘭州攀鋼鍍鋅隨著鋼結構在建筑材料中的興起，越來越多的人選擇使用鋼結構樓承板了，鋼結構構件工廠產業化生產大大縮短了工程工期，而樓板的施工方法卻成為影響工期的重要因素。采用那一代樓承板對于樓板的耐火性能也有區別。鍍鋅批發樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)的厚(hou)度(du)(du)一般(ban)都是(shi)(shi)按保險起見設計的比較厚(hou)，正常情況(kuang)下鋼(gang)梁之(zhi)間的跨度(du)(du)在2m以內(nei)樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)厚(hou)度(du)(du)在0.75-0.8mm就可(ke)以了，2-2.5m樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)厚(hou)度(du)(du)用(yong)0.8-1.0就可(ke)以了，跨度(du)(du)在3-4米樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)厚(hou)度(du)(du)用(yong)1.5mm，超(chao)過5m的跨度(du)(du)是(shi)(shi)用(yong)臨時支撐，因素就是(shi)(shi)混(hun)泥土澆(jiao)筑的高(gao)度(du)(du)，混(hun)泥土澆(jiao)筑的越高(gao)，樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)所需(xu)要的厚(hou)度(du)(du)也就越厚(hou)，還有一個(ge)大家容易忽略的因素就是(shi)(shi)螺釘的好壞也是(shi)(shi)決定樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)厚(hou)度(du)(du)的，螺釘越好樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)的承(cheng)(cheng)(cheng)載力就越強(qiang)。

熱鍍(du)(du)(du)(du)鋅(xin)板(ban)(ban)(ban)和(he)電鍍(du)(du)(du)(du)鋅(xin)板(ban)(ban)(ban)在鍍(du)(du)(du)(du)鋅(xin)量上有很(hen)大(da)的差別，就像山(shan)東彩涂(tu)卷）。熱鍍(du)(du)(du)(du)鋅(xin)的鍍(du)(du)(du)(du)鋅(xin)量不可能太小，一般(ban)(ban)較(jiao)小為雙(shuang)面50～60g／m2，較(jiao)大(da)可達600g／m2。電鍍(du)(du)(du)(du)鋅(xin)板(ban)(ban)(ban)的鍍(du)(du)(du)(du)鋅(xin)層可以很(hen)薄(bo)，較(jiao)小達15g／m2，但要求鍍(du)(du)(du)(du)層較(jiao)厚的話則生產線速度很(hen)慢(man)，不適(shi)應(ying)現代(dai)化機組的工藝特點，一般(ban)(ban)較(jiao)大(da)為lO0g／m2左右。正(zheng)因(yin)為如此，電鍍(du)(du)(du)(du)鋅(xin)板(ban)(ban)(ban)的生產受到很(hen)大(da)的限制。工一般(ban)(ban)電鍍(du)(du)(du)(du)鋅(xin)比較(jiao)多，適(shi)用于(yu)小部(bu)件；熱鍍(du)(du)(du)(du)鋅(xin)一般(ban)(ban)用于(yu)電力設(she)(she)備(bei)和(he)構件，適(shi)用于(yu)大(da)的部(bu)件和(he)設(she)(she)備(bei)。當(dang)然他們的價格也相(xiang)對便(bian)宜一些。建設(she)(she)部(bu)已正(zheng)式下文(wen)，淘汰(tai)技術落(luo)后的冷鍍(du)(du)(du)(du)鋅(xin)管，不準(zhun)用冷鍍(du)(du)(du)(du)鋅(xin)管作水、煤氣管。

熱(re)鍍(du)鋅卷板(ban)現貨(huo)消(xiao)息：熱(re)鍍(du)鋅產(chan)品廣泛用(yong)于建筑、家(jia)電、車(che)(che)船、容器制造業(ye)、機電業(ye)等，幾乎涉(she)及到衣(yi)食(shi)住行各個(ge)領域。近年來(lai)(lai)，世界鍍(du)鋅鋼板(ban)需求量不(bu)斷增加，產(chan)量增長也很快，在美、日等鋼材生產(chan)大國，熱(re)鍍(du)鋅鋼板(ban)在鋼材中所占比(bi)例已高(gao)達13%-15%。 熱(re)鍍(du)鋅卷板(ban)現貨(huo)消(xiao)息：近來(lai)(lai)，汽車(che)(che)行業(ye)越來(lai)(lai)越重視(shi)材料的(de)使用(yong)壽命，用(yong)涂漆(qi)冷軋鋼板(ban)已不(bu)能(neng)滿足耐腐蝕(shi)方面的(de)要求。在這種(zhong)情況下，耐腐蝕(shi)性優良且成本(ben)低廉(lian)的(de)熱(re)鍍(du)鋅板(ban)開始普(pu)遍(bian)受到了汽車(che)(che)廠家(jia)的(de)青睞。
