重慶鍍鋅(xin)(xin)板(ban)(ban)近(jin)二十年來(lai)鋼(gang)帶(dai)連續熱鍍鋅(xin)(xin)技術(shu)(shu)、裝備以及相應的(de)控制手段均(jun)有巨大的(de)發展，使鍍鋅(xin)(xin)板(ban)(ban)得以滿足汽車(che)面板(ban)(ban)和家電用(yong)板(ban)(ban)的(de)苛刻要求(qiu)，并從而(er)(er)以其比電鍍鋅(xin)(xin)合(he)金鋼(gang)帶(dai)廉價(jia)、耐蝕性優(you)異而(er)(er)大有取代之勢(shi)。熱鍍鋅(xin)(xin)生產技術(shu)(shu)與裝備開(kai)發技術(shu)(shu)及經驗，通過技術(shu)(shu)創新、優(you)化設計、精密制造以及國(guo)(guo)外(wai)技術(shu)(shu)合(he)作，突破(po)制約(yue)我(wo)國(guo)(guo)高性能(neng)汽車(che)用(yong)熱鍍鋅(xin)(xin)鋼(gang)板(ban)(ban)生產技術(shu)(shu)與裝備發展瓶頸。

鍍鋅鋼批發鍍鋅是一種經常采用的經濟而有效的防腐方法。鋅產量的一半左右均用于此種工藝。鍍鋅卷是為防止鋼板表面遭受腐蝕延長其使用壽命，在鋼板表面涂以一層金屬鋅，這種涂鋅的鋼板稱為鍍鋅卷。資陽鍍鋅鋼鍍鋅卷(juan)主(zhu)要用于建筑、家(jia)電、汽車、容器(qi)、交通及(ji)家(jia)業等(deng)領域(yu)。特別(bie)是鋼(gang)結構建筑、汽車制造(zao)、鋼(gang)板(ban)(ban)倉制造(zao)等(deng)行(xing)業。耐腐蝕強、表面質(zhi)量好、得利于深加工、經濟實用等(deng)。有關產品標準(zhun)(zhun)都列(lie)明鍍鋅卷(juan)推薦的標準(zhun)(zhun)厚(hou)度、長度和寬度及(ji)其允許偏差(cha)。鍍鋅卷(juan)厚(hou)度偏差(cha)一(yi)般(ban)在(zai)0.05mm，長寬偏差(cha)一(yi)般(ban)在(zai)5mm ，板(ban)(ban)材(cai)的厚(hou)度一(yi)般(ban)在(zai)0.2-3.2之間 。

重慶(qing)樓(lou)承(cheng)板(ban)(ban)(ban)的鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)量(liang)沒有一個具體的標(biao)準，制作壓(ya)型鋼(gang)板(ban)(ban)(ban)的冷軋鋼(gang)卷須連續熱(re)浸鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)（或鍍(du)(du)(du)(du)(du)(du)鋁鋅(xin)(xin)(xin)(xin)），鍍(du)(du)(du)(du)(du)(du)（鋁）鋅(xin)(xin)(xin)(xin)量(liang)視(shi)設計要求而定。樓(lou)承(cheng)板(ban)(ban)(ban)用壓(ya)型鋼(gang)板(ban)(ban)(ban)宜選(xuan)擇熱(re)浸鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。不允(yun)許使用電鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)，電鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)僅在(zai)(zai)基材表(biao)面(mian)形成保護(hu)層，防腐能(neng)力有限(xian)。目前市場(chang)上有鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)（鍍(du)(du)(du)(du)(du)(du)層含(han)鋁5%或55%），在(zai)(zai)酸性環境下(xia)的防腐效果(guo)由于熱(re)浸鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)，但在(zai)(zai)混(hun)凝(ning)土的堿性條(tiao)件下(xia)，鍍(du)(du)(du)(du)(du)(du)鋁鋅(xin)(xin)(xin)(xin)的防腐蝕性能(neng)低于熱(re)浸鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)，且鋁會和混(hun)凝(ning)土發生反應，并(bing)降(jiang)低混(hun)凝(ning)土與鋼(gang)板(ban)(ban)(ban)的粘(zhan)結性能(neng)。因此參考國外規(gui)范，及國內外工程，行家壓(ya)型鋼(gang)板(ban)(ban)(ban)不建議使用鍍(du)(du)(du)(du)(du)(du)鋁鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。

樓(lou)承(cheng)板(ban)的使用(yong)(yong)(yong)是(shi)需(xu)(xu)要(yao)安裝的，那么(me)如果要(yao)安裝就(jiu)要(yao)選擇合適的小配件，焊后栓(shuan)(shuan)釘(ding)(ding)高(gao)(gao)度(du)(du)大于(yu)壓型鋼(gang)板(ban)波高(gao)(gao)30MM(留(liu)(liu)意挑選樓(lou)板(ban)的類型);栓(shuan)(shuan)釘(ding)(ding)頂面(mian)混凝(ning)土保護層不小于(yu)15MM(留(liu)(liu)意樓(lou)板(ban)總(zong)厚(hou)(hou)(hou)度(du)(du))直徑(jing)不宜大于(yu)19MM。樓(lou)承(cheng)板(ban)栓(shuan)(shuan)釘(ding)(ding)類型有(you)ф8、ф10、ф13、ф16、ф19、ф22、ф25，栓(shuan)(shuan)釘(ding)(ding)一般在鋼(gang)結(jie)構(gou)(gou)修建中(zhong),遍及使用(yong)(yong)(yong)在柱腳(jiao)和樓(lou)板(ban)中(zhong),一般剛度(du)(du)要(yao)求(qiu)高(gao)(gao)的柱腳(jiao)都選用(yong)(yong)(yong)鋼(gang)柱內伸至混凝(ning)土中(zhong)，鋼(gang)柱埋入混凝(ning)土的部(bu)位四周(zhou)均布栓(shuan)(shuan)釘(ding)(ding)。樓(lou)承(cheng)板(ban)輕鋼(gang)結(jie)構(gou)(gou)常用(yong)(yong)(yong)厚(hou)(hou)(hou)度(du)(du)為0.8mm,1.0mm，1.2mm,荷載較大的情況(kuang)下會用(yong)(yong)(yong)到(dao)1.5mm。一般需(xu)(xu)要(yao)用(yong)(yong)(yong)栓(shuan)(shuan)釘(ding)(ding)與鋼(gang)梁銜接，板(ban)中(zhong)配少(shao)量鋼(gang)筋，上面(mian)澆混凝(ning)土層，總(zong)厚(hou)(hou)(hou)度(du)(du)約在100-200mm之間。

鍍(du)(du)(du)(du)鋅(xin)(xin)鋼板(ban)的(de)(de)表(biao)面(mian)鍍(du)(du)(du)(du)鋅(xin)(xin)主要采(cai)用(yong)的(de)(de)方(fang)法(fa)是(shi)熱鍍(du)(du)(du)(du)鋅(xin)(xin)。熱鍍(du)(du)(du)(du)鋅(xin)(xin)是(shi)由較(jiao)古(gu)老(lao)的(de)(de)熱鍍(du)(du)(du)(du)方(fang)法(fa)發展而來的(de)(de)，自從1836年法(fa)國把熱鍍(du)(du)(du)(du)鋅(xin)(xin)應用(yong)于工(gong)業(ye)以(yi)來，已(yi)經有(you)一百(bai)七十年的(de)(de)歷史(shi)了。然而，熱鍍(du)(du)(du)(du)鋅(xin)(xin)工(gong)業(ye)是(shi)近(jin)三(san)十年來伴隨冷軋帶鋼的(de)(de)飛速發展而得到了大(da)規模發展。鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)(rong)液(ye)(ye)(ye)有(you)氰(qing)化(hua)物鍍(du)(du)(du)(du)液(ye)(ye)(ye)和無氰(qing)鍍(du)(du)(du)(du)液(ye)(ye)(ye)兩(liang)類(lei)。氰(qing)化(hua)物鍍(du)(du)(du)(du)液(ye)(ye)(ye)中(zhong)分(fen)微氰(qing)、低氰(qing)、中(zhong)氰(qing)、和高(gao)氰(qing)幾類(lei)。無氰(qing)鍍(du)(du)(du)(du)液(ye)(ye)(ye)有(you)堿性鋅(xin)(xin)酸鹽(yan)鍍(du)(du)(du)(du)液(ye)(ye)(ye)、銨鹽(yan)鍍(du)(du)(du)(du)液(ye)(ye)(ye)、硫(liu)酸鹽(yan)鍍(du)(du)(du)(du)液(ye)(ye)(ye)及無氨氯(lv)化(hua)物鍍(du)(du)(du)(du)液(ye)(ye)(ye)等。氰(qing)化(hua)鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)(rong)液(ye)(ye)(ye)均鍍(du)(du)(du)(du)能(neng)力好，得到的(de)(de)鍍(du)(du)(du)(du)層光滑細(xi)致(zhi)，在生產中(zhong)被長期采(cai)用(yong)。但由于氰(qing)化(hua)物劇(ju)毒，對環境(jing)污(wu)染嚴重，近(jin)年來已(yi)趨向(xiang)于采(cai)用(yong)低氰(qing)、微氰(qing)、無氰(qing)鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)(rong)液(ye)(ye)(ye)。

鍍鋅(xin)鋼板(ban)按(an)用(yong)(yong)(yong)途又可(ke)(ke)分為一(yi)般(ban)(ban)用(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)、建(jian)筑外側板(ban)用(yong)(yong)(yong)、結(jie)(jie)構用(yong)(yong)(yong)、瓦壟板(ban)用(yong)(yong)(yong)、拉伸(shen)用(yong)(yong)(yong)和深沖用(yong)(yong)(yong)等(deng)鍍鋅(xin)鋼板(ban)。對于一(yi)般(ban)(ban)防保護用(yong)(yong)(yong)鍍層，可(ke)(ke)以采(cai)用(yong)(yong)(yong)堿性(xing)(xing)鋅(xin)酸鹽鍍鋅(xin)彩色(se)(se)鈍(dun)(dun)化(hua)工(gong)藝(yi)。有(you)(you)時為了(le)產(chan)品的(de)(de)配色(se)(se)需要，也可(ke)(ke)以采(cai)用(yong)(yong)(yong)藍白(bai)色(se)(se)鈍(dun)(dun)化(hua)工(gong)藝(yi)，比如軍綠色(se)(se)鈍(dun)(dun)化(hua)、黑色(se)(se)鈍(dun)(dun)化(hua)等(deng)。為提高鋼管(guan)(guan)的(de)(de)耐腐蝕(shi)性(xing)(xing)能，對一(yi)般(ban)(ban)鋼管(guan)(guan)進(jin)行鍍鋅(xin)。鍍鋅(xin)卷分熱鍍鋅(xin)和電鍍鋅(xin)兩種，熱鍍鋅(xin)鍍鋅(xin)層厚，電鍍鋅(xin)成(cheng)(cheng)本低(di)，表面不是很光滑。吹(chui)氧焊管(guan)(guan)：用(yong)(yong)(yong)作(zuo)煉鋼吹(chui)氧用(yong)(yong)(yong)管(guan)(guan)，一(yi)般(ban)(ban)用(yong)(yong)(yong)小口徑的(de)(de)焊接(jie)鋼管(guan)(guan)，規(gui)格由3/8-2寸八種。用(yong)(yong)(yong)08、10、15、20或者195-Q235的(de)(de)鋼帶制作(zuo)成(cheng)(cheng)的(de)(de)，為了(le)防腐蝕(shi)，有(you)(you)得進(jin)行滲鋁處理。鍍鋅(xin)其防護作(zuo)用(yong)(yong)(yong)更強，抗腐蝕(shi)能力強。整個(ge)結(jie)(jie)構由鋅(xin)，形(xing)成(cheng)(cheng)致密(mi)的(de)(de)四(si)元結(jie)(jie)晶(jing)體，此結(jie)(jie)晶(jing)體在鋼板(ban)上形(xing)成(cheng)(cheng)一(yi)層屏障(zhang)， 因而有(you)(you)效的(de)(de)防止腐蝕(shi)因子穿透。 耐腐蝕(shi)性(xing)(xing)來自鋅(xin)的(de)(de)障(zhang)礙層保護功能強。
