鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板按用(yong)(yong)(yong)(yong)途又可分為(wei)一(yi)般用(yong)(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)(yong)、建筑外(wai)側板用(yong)(yong)(yong)(yong)、結(jie)構用(yong)(yong)(yong)(yong)、瓦壟板用(yong)(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)(yong)和深沖用(yong)(yong)(yong)(yong)等鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板。對于一(yi)般防保(bao)(bao)護用(yong)(yong)(yong)(yong)鍍(du)層(ceng)(ceng)，可以采(cai)用(yong)(yong)(yong)(yong)堿(jian)性鋅(xin)(xin)(xin)酸鹽鍍(du)鋅(xin)(xin)(xin)彩(cai)色鈍(dun)化工(gong)藝。有時為(wei)了(le)產品的配色需要(yao)，也(ye)可以采(cai)用(yong)(yong)(yong)(yong)藍白色鈍(dun)化工(gong)藝，比如軍綠色鈍(dun)化、黑色鈍(dun)化等。為(wei)提高鋼(gang)(gang)管(guan)(guan)的耐腐(fu)蝕(shi)(shi)性能(neng)，對一(yi)般鋼(gang)(gang)管(guan)(guan)進行鍍(du)鋅(xin)(xin)(xin)。鍍(du)鋅(xin)(xin)(xin)卷(juan)分熱鍍(du)鋅(xin)(xin)(xin)和電(dian)鍍(du)鋅(xin)(xin)(xin)兩種(zhong)，熱鍍(du)鋅(xin)(xin)(xin)鍍(du)鋅(xin)(xin)(xin)層(ceng)(ceng)厚，電(dian)鍍(du)鋅(xin)(xin)(xin)成(cheng)本低，表面不是很光滑。吹氧(yang)焊管(guan)(guan)：用(yong)(yong)(yong)(yong)作(zuo)煉鋼(gang)(gang)吹氧(yang)用(yong)(yong)(yong)(yong)管(guan)(guan)，一(yi)般用(yong)(yong)(yong)(yong)小口(kou)徑的焊接(jie)鋼(gang)(gang)管(guan)(guan)，規格由(you)3/8-2寸(cun)八種(zhong)。用(yong)(yong)(yong)(yong)08、10、15、20或者195-Q235的鋼(gang)(gang)帶制(zhi)作(zuo)成(cheng)的，為(wei)了(le)防腐(fu)蝕(shi)(shi)，有得進行滲鋁(lv)處理。鍍(du)鋅(xin)(xin)(xin)其(qi)防護作(zuo)用(yong)(yong)(yong)(yong)更(geng)強(qiang)，抗腐(fu)蝕(shi)(shi)能(neng)力強(qiang)。整個結(jie)構由(you)鋅(xin)(xin)(xin)，形成(cheng)致(zhi)密(mi)的四元結(jie)晶(jing)體，此結(jie)晶(jing)體在(zai)鋼(gang)(gang)板上形成(cheng)一(yi)層(ceng)(ceng)屏(ping)障(zhang)， 因(yin)而有效的防止腐(fu)蝕(shi)(shi)因(yin)子(zi)穿透。 耐腐(fu)蝕(shi)(shi)性來自鋅(xin)(xin)(xin)的障(zhang)礙(ai)層(ceng)(ceng)保(bao)(bao)護功能(neng)強(qiang)。

樓(lou)(lou)承板(ban)(ban)鍍(du)(du)鋅(xin)(xin)首要起(qi)到防腐的(de)效果，按標準(zhun)組(zu)(zu)(zu)合(he)樓(lou)(lou)板(ban)(ban)與非組(zu)(zu)(zu)合(he)樓(lou)(lou)板(ban)(ban)壓型鋼板(ban)(ban)應選(xuan)用(yong)熱鍍(du)(du)鋅(xin)(xin)，不(bu)該選(xuan)用(yong)電鍍(du)(du)鋅(xin)(xin)鋼板(ban)(ban)，其雙(shuang)面鍍(du)(du)鋅(xin)(xin)層總含(han)量(liang)(liang)要滿足在使(shi)用(yong)期間不(bu)致銹(xiu)損的(de)要求。當作為(wei)(wei)非組(zu)(zu)(zu)合(he)樓(lou)(lou)承板(ban)(ban)時，鍍(du)(du)鋅(xin)(xin)層含(han)量(liang)(liang)可(ke)選(xuan)用(yong)較(jiao)低值;當為(wei)(wei)組(zu)(zu)(zu)合(he)樓(lou)(lou)承板(ban)(ban)時，鍍(du)(du)鋅(xin)(xin)層含(han)量(liang)(liang)不(bu)該小于150g/m2。當為(wei)(wei)組(zu)(zu)(zu)合(he)樓(lou)(lou)板(ban)(ban)且使(shi)用(yong)環境條件(jian)較(jiao)為(wei)(wei)惡劣時，鍍(du)(du)鋅(xin)(xin)層含(han)量(liang)(liang)應選(xuan)用(yong)上限值或更高值。更高的(de)鍍(du)(du)鋅(xin)(xin)要求，如雙(shuang)面鍍(du)(du)鋅(xin)(xin)量(liang)(liang)為(wei)(wei)300g/m2、350g/m2或鍍(du)(du)鋁(lv)鋅(xin)(xin)(5%鋁(lv))275g/m2、300g/m2等，較(jiao)高的(de)鍍(du)(du)層量(liang)(liang)使(shi)組(zu)(zu)(zu)合(he)樓(lou)(lou)板(ban)(ban)有更長耐(nai)久性，同等量(liang)(liang)的(de)鍍(du)(du)鋁(lv)鋅(xin)(xin)的(de)防銹(xiu)蝕才(cai)能大約兩倍于一(yi)般熱鍍(du)(du)鋅(xin)(xin)。鍍(du)(du)鋅(xin)(xin)量(liang)(liang)也不(bu)是越厚越好(hao)，當鍍(du)(du)鋅(xin)(xin)量(liang)(liang)較(jiao)厚時，抗(kang)剪連接件(jian)栓釘的(de)焊(han)接質量(liang)(liang)就很(hen)難(nan)保證(zheng)，焊(han)接時，宜選(xuan)用(yong)局部除鋅(xin)(xin)處理措施。

鍍鋅鋼板廠家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。昆山鍍鋅鋼板鍍鋅卷(juan)主(zhu)要用于建筑(zhu)、家(jia)電、汽車(che)、容(rong)器(qi)、交(jiao)通及家(jia)業等領域。特(te)別是鋼結構建筑(zhu)、汽車(che)制造、鋼板倉制造等行業。耐腐蝕強、表面質量好、得利于深(shen)加工、經濟實用等。有關產品(pin)標準(zhun)都列明(ming)鍍鋅卷(juan)推薦的(de)標準(zhun)厚度(du)、長度(du)和寬度(du)及其允許偏(pian)差。鍍鋅卷(juan)厚度(du)偏(pian)差一般在0.05mm，長寬偏(pian)差一般在5mm ，板材的(de)厚度(du)一般在0.2-3.2之間 。

鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼板的表面鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)主要采用(yong)的方法(fa)是(shi)熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)。熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)是(shi)由較古老的熱鍍(du)(du)(du)(du)(du)方法(fa)發展而(er)來的，自從1836年法(fa)國(guo)把熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)應用(yong)于(yu)(yu)工業(ye)以來，已經有(you)一百七十年的歷史了(le)。然而(er)，熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)工業(ye)是(shi)近(jin)三(san)十年來伴隨冷軋帶鋼的飛速發展而(er)得到(dao)了(le)大規模發展。鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)(rong)液(ye)(ye)(ye)(ye)(ye)有(you)氰(qing)(qing)化物(wu)鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)和(he)無(wu)氰(qing)(qing)鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)兩類。氰(qing)(qing)化物(wu)鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)中分微氰(qing)(qing)、低(di)氰(qing)(qing)、中氰(qing)(qing)、和(he)高氰(qing)(qing)幾類。無(wu)氰(qing)(qing)鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)有(you)堿性鋅(xin)(xin)(xin)酸鹽鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)、銨鹽鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)、硫酸鹽鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)及(ji)無(wu)氨氯化物(wu)鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)(ye)(ye)等(deng)。氰(qing)(qing)化鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)(rong)液(ye)(ye)(ye)(ye)(ye)均鍍(du)(du)(du)(du)(du)能力好(hao)，得到(dao)的鍍(du)(du)(du)(du)(du)層(ceng)光滑細致，在生(sheng)產中被(bei)長期采用(yong)。但由于(yu)(yu)氰(qing)(qing)化物(wu)劇毒，對環境污染嚴重，近(jin)年來已趨向于(yu)(yu)采用(yong)低(di)氰(qing)(qing)、微氰(qing)(qing)、無(wu)氰(qing)(qing)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶(rong)(rong)液(ye)(ye)(ye)(ye)(ye)。
