鍍鋅廠家鍍鋅鋼板的表面鍍鋅主要采用的方法是熱鍍鋅。云南鍍鋅熱(re)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)是由較(jiao)古老(lao)的(de)(de)(de)熱(re)鍍(du)(du)(du)(du)(du)(du)(du)方(fang)法發(fa)展而來(lai)的(de)(de)(de)，自從(cong)1836年(nian)法國把(ba)熱(re)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)應用于工(gong)(gong)業(ye)以來(lai)，已經有(you)一百七十年(nian)的(de)(de)(de)歷史了(le)(le)。然而，熱(re)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)工(gong)(gong)業(ye)是近三十年(nian)來(lai)伴隨冷軋帶鋼的(de)(de)(de)飛速發(fa)展而得(de)到了(le)(le)大規模發(fa)展。鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)溶液(ye)有(you)氰(qing)(qing)(qing)化(hua)物鍍(du)(du)(du)(du)(du)(du)(du)液(ye)和(he)無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)(du)(du)(du)液(ye)兩類(lei)。氰(qing)(qing)(qing)化(hua)物鍍(du)(du)(du)(du)(du)(du)(du)液(ye)中分(fen)微(wei)氰(qing)(qing)(qing)、低氰(qing)(qing)(qing)、中氰(qing)(qing)(qing)、和(he)高氰(qing)(qing)(qing)幾(ji)類(lei)。無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)(du)(du)(du)液(ye)有(you)堿性鋅(xin)酸(suan)鹽(yan)鍍(du)(du)(du)(du)(du)(du)(du)液(ye)、銨鹽(yan)鍍(du)(du)(du)(du)(du)(du)(du)液(ye)、硫酸(suan)鹽(yan)鍍(du)(du)(du)(du)(du)(du)(du)液(ye)及無氨(an)氯化(hua)物鍍(du)(du)(du)(du)(du)(du)(du)液(ye)等(deng)。氰(qing)(qing)(qing)化(hua)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)溶液(ye)均(jun)鍍(du)(du)(du)(du)(du)(du)(du)能力好(hao)，得(de)到的(de)(de)(de)鍍(du)(du)(du)(du)(du)(du)(du)層(ceng)光滑細(xi)致，在(zai)生(sheng)產中被長期采(cai)用。但由于氰(qing)(qing)(qing)化(hua)物劇毒，對環(huan)境污染嚴重，近年(nian)來(lai)已趨向于采(cai)用低氰(qing)(qing)(qing)、微(wei)氰(qing)(qing)(qing)、無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)(du)(du)(du)鋅(xin)溶液(ye)。

鍍鋅鋼板(ban)按(an)用(yong)途又(you)可分(fen)為一般(ban)(ban)用(yong)、屋頂用(yong)、建筑(zhu)外側板(ban)用(yong)、結構(gou)用(yong)、瓦壟板(ban)用(yong)、拉伸(shen)用(yong)和深(shen)沖用(yong)等(deng)鍍鋅鋼板(ban)。熱鍍鋅板(ban)主要應用(yong)于建筑(zhu)外用(yong)，建筑(zhu)內用(yong)，民用(yong)，門窗，家(jia)(jia)具，機械，電子及(ji)家(jia)(jia)用(yong)電器(qi)等(deng)領域(yu)。也有機箱用(yong)這個，不過熱鍍鋅板(ban)不放(fang)輻射的(de)。空調，冰箱，微波(bo)爐及(ji)其類似(si)家(jia)(jia)電背面(mian)的(de)那個板(ban)就是(shi)熱鍍鋅板(ban)。鍍鋅層通(tong)過鈍化(hua)處(chu)理，可減少(shao)潮溫貯運條件下(xia)產生折(zhe)銹蝕(shi)(白銹) 。但這種化(hua)學(xue)處(chu)理的(de)防腐蝕(shi)性能(neng)是(shi)有限的(de)，而(er)且，妨礙(ai)大多數涂料的(de)附著性。這種處(chu)理一般(ban)(ban)不用(yong)在鋅鐵合金鍍層，除光整表面(mian)外，作為常規(gui)，生產廠對其他類型的(de)鍍鋅層均進行鈍化(hua)處(chu)理。

樓(lou)承(cheng)板(ban)(ban)(ban)鋼(gang)(gang)筋桁(heng)(heng)(heng)架(jia)是將(jiang)樓(lou)板(ban)(ban)(ban)中(zhong)(zhong)的(de)(de)(de)鋼(gang)(gang)筋在工(gong)廠采用進(jin)口(kou)設(she)備(bei)加工(gong)成(cheng)鋼(gang)(gang)筋桁(heng)(heng)(heng)架(jia)，并(bing)將(jiang)鋼(gang)(gang)筋桁(heng)(heng)(heng)架(jia)與(yu)鍍鋅鋼(gang)(gang)板(ban)(ban)(ban)在工(gong)廠焊(han)接成(cheng)一(yi)體的(de)(de)(de)組合(he)模(mo)板(ban)(ban)(ban)，使其在施工(gong)階段(duan)可作為(wei)鋼(gang)(gang)梁的(de)(de)(de)側向(xiang)(xiang)支撐(cheng)使用！樓(lou)板(ban)(ban)(ban)連接采用扣合(he)方(fang)式，板(ban)(ban)(ban)與(yu)板(ban)(ban)(ban)之間的(de)(de)(de)拉(la)鉤連接應緊密，保(bao)(bao)證澆筑混凝(ning)土時(shi)不漏漿(jiang)，同(tong)時(shi)注(zhu)(zhu)意排(pai)板(ban)(ban)(ban)方(fang)向(xiang)(xiang)要一(yi)致(zhi)，桁(heng)(heng)(heng)架(jia)節點間距為(wei)200㎜，注(zhu)(zhu)意不同(tong)模(mo)板(ban)(ban)(ban)的(de)(de)(de)橫向(xiang)(xiang)節點要對齊。我們仔細觀察的(de)(de)(de)話會(hui)發現很(hen)多高(gao)層(ceng)建(jian)(jian)筑上都會(hui)設(she)置鋼(gang)(gang)筋桁(heng)(heng)(heng)架(jia)樓(lou)承(cheng)板(ban)(ban)(ban)，我們雖然經常用到該(gai)(gai)樓(lou)承(cheng)板(ban)(ban)(ban)，但很(hen)少有(you)人知道(dao)這(zhe)種板(ban)(ban)(ban)材為(wei)什么會(hui)用于高(gao)層(ceng)建(jian)(jian)筑中(zhong)(zhong)。下面小編將(jiang)為(wei)您介紹一(yi)下該(gai)(gai)板(ban)(ban)(ban)材在高(gao)層(ceng)建(jian)(jian)筑中(zhong)(zhong)的(de)(de)(de)使用優勢！鋼(gang)(gang)筋樓(lou)承(cheng)板(ban)(ban)(ban)的(de)(de)(de)搭(da)接是有(you)著嚴格的(de)(de)(de)施工(gong)要求的(de)(de)(de)，為(wei)保(bao)(bao)障樓(lou)承(cheng)板(ban)(ban)(ban)安(an)裝牢固，該(gai)(gai)板(ban)(ban)(ban)材的(de)(de)(de)搭(da)接需要按照(zhao)說(shuo)明(ming)書正(zheng)確進(jin)行，搭(da)接過(guo)程中(zhong)(zhong)還需要注(zhu)(zhu)意，沿順肋方(fang)向(xiang)(xiang)，壓型鋼(gang)(gang)板(ban)(ban)(ban)如果可以滿足正(zheng)截面承(cheng)載力及剪(jian)切(qie)粘結承(cheng)載力的(de)(de)(de)要求，可以不用配順肋方(fang)向(xiang)(xiang)的(de)(de)(de)鋼(gang)(gang)筋，這(zhe)時(shi)候(hou)要注(zhu)(zhu)意計算(suan)剪(jian)切(qie)粘結承(cheng)載力。

鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)是(shi)(shi)為防止鋼(gang)(gang)板(ban)(ban)(ban)(ban)表面遭受腐蝕，延(yan)長其使(shi)用(yong)(yong)壽命，在(zai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)表面涂以一層(ceng)金屬鋅(xin)(xin)，這種涂鋅(xin)(xin)的薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)稱為鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)。按生(sheng)產(chan)及加(jia)工(gong)方法可分為以下幾類：熱(re)(re)浸(jin)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)浸(jin)入熔 微商貨源(yuan)解的鋅(xin)(xin)槽中(zhong)(zhong)，使(shi)其表面粘附一層(ceng)鋅(xin)(xin)的薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。目前(qian)主要采用(yong)(yong)連(lian)續鍍(du)(du)(du)鋅(xin)(xin)工(gong)藝(yi)生(sheng)產(chan)，即把成卷(juan)的鋼(gang)(gang)板(ban)(ban)(ban)(ban)連(lian)續浸(jin)在(zai)熔解有(you)鋅(xin)(xin)的鍍(du)(du)(du)槽中(zhong)(zhong)制成鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)；合金化鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。這種鋼(gang)(gang)板(ban)(ban)(ban)(ban)也(ye)是(shi)(shi)用(yong)(yong)熱(re)(re)浸(jin)法制造，但在(zai)出槽后，立即把它加(jia)熱(re)(re)到５００℃左右，使(shi)其生(sheng)成鋅(xin)(xin)和(he)鐵(tie)的合金被膜(mo)。這種鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)具有(you)良好的涂料的密著性和(he)焊接性。

首先(xian)，在鋼結(jie)構(gou)(gou)樓(lou)層(ceng)板(ban)中要(yao)達(da)到耐火1.5小時(shi)，總的來說可(ke)以選擇開口(kou)(kou)(kou)板(ban)、縮口(kou)(kou)(kou)板(ban)、閉口(kou)(kou)(kou)板(ban)三大類。規范上混凝土要(yao)高于(yu)開口(kou)(kou)(kou)板(ban)肋頂(ding)之(zhi)上80mm，并且板(ban)底(di)(di)需(xu)(xu)配置板(ban)底(di)(di)受力(li)筋(jin)。還有一種就(jiu)是再開口(kou)(kou)(kou)板(ban)底(di)(di)部(bu)刷防火涂料，涂料厚(hou)度大于(yu)等于(yu)15,這樣的話，只要(yao)達(da)到構(gou)(gou)造要(yao)求(qiu)高于(yu)肋頂(ding)5公(gong)分就(jiu)可(ke)以了。而(er)縮口(kou)(kou)(kou)板(ban)和閉口(kou)(kou)(kou)板(ban)，只需(xu)(xu)要(yao)總的樓(lou)板(ban)厚(hou)度大于(yu)等于(yu)110即可(ke)，但(dan)是縮口(kou)(kou)(kou)板(ban)雖然在防火方面比開口(kou)(kou)(kou)板(ban)要(yao)好。但(dan)是底(di)(di)部(bu)還是需(xu)(xu)要(yao)加板(ban)底(di)(di)受力(li)筋(jin)，而(er)閉口(kou)(kou)(kou)板(ban)則不需(xu)(xu)要(yao)。

鍍(du)鋅(xin)(xin)(xin)(xin)方管(guan)是(shi)一種(zhong)具以熱軋或(huo)冷軋鍍(du)鋅(xin)(xin)(xin)(xin)帶鋼(gang)(gang)或(huo)鍍(du)鋅(xin)(xin)(xin)(xin)卷板為(wei)坯料經(jing)(jing)冷彎曲(qu)加(jia)工成型(xing)(xing)后再經(jing)(jing)高頻焊(han)接制成的(de)(de)(de)(de)(de)方形(xing)(xing)截面形(xing)(xing)狀尺寸的(de)(de)(de)(de)(de)空心(xin)方形(xing)(xing)的(de)(de)(de)(de)(de)截面型(xing)(xing)鋼(gang)(gang)鋼(gang)(gang)管(guan)；鍍(du)鋅(xin)(xin)(xin)(xin)卷或(huo)將事(shi)先(xian)做好的(de)(de)(de)(de)(de)冷彎空心(xin)型(xing)(xing)鋼(gang)(gang)管(guan)再經(jing)(jing)熱浸鍍(du)鋅(xin)(xin)(xin)(xin)加(jia)工而(er)成的(de)(de)(de)(de)(de)鍍(du)鋅(xin)(xin)(xin)(xin)方矩(ju)管(guan)。鍍(du)鋅(xin)(xin)(xin)(xin)量是(shi)表示鍍(du)鋅(xin)(xin)(xin)(xin)板鋅(xin)(xin)(xin)(xin)層厚度的(de)(de)(de)(de)(de)一個(ge)普遍采用(yong)的(de)(de)(de)(de)(de)有效方法(fa)。鍍(du)鋅(xin)(xin)(xin)(xin)量的(de)(de)(de)(de)(de)單位(wei)為(wei)g/m2。鍍(du)鋅(xin)(xin)(xin)(xin)層通過鈍化處理，可(ke)減(jian)少潮溫貯運條件下(xia)產生折銹蝕(白銹) 。但這種(zhong)化學(xue)處理的(de)(de)(de)(de)(de)防腐(fu)蝕性能是(shi)有限(xian)的(de)(de)(de)(de)(de)，而(er)且(qie)，妨(fang)礙大多數(shu)涂料的(de)(de)(de)(de)(de)附著(zhu)性。這種(zhong)處理一般(ban)不用(yong)在(zai)鋅(xin)(xin)(xin)(xin)鐵合(he)金鍍(du)層，除光整表面外(wai)，作為(wei)常規，生產廠(chang)對其(qi)他類(lei)型(xing)(xing)的(de)(de)(de)(de)(de)鍍(du)鋅(xin)(xin)(xin)(xin)層均進行鈍化處理。
