鍍(du)(du)(du)(du)鋅(xin)鋼(gang)板按用(yong)(yong)(yong)(yong)途(tu)又可(ke)(ke)分為(wei)一般用(yong)(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)(yong)、建(jian)筑外側(ce)板用(yong)(yong)(yong)(yong)、結構用(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)(du)(du)(du)鋅(xin)鋼(gang)板。熱鍍(du)(du)(du)(du)鋅(xin)板主要應用(yong)(yong)(yong)(yong)于建(jian)筑外用(yong)(yong)(yong)(yong)，建(jian)筑內用(yong)(yong)(yong)(yong)，民用(yong)(yong)(yong)(yong)，門窗，家具，機械，電(dian)(dian)子及(ji)家用(yong)(yong)(yong)(yong)電(dian)(dian)器等領(ling)域。也有機箱(xiang)用(yong)(yong)(yong)(yong)這(zhe)個，不(bu)過(guo)(guo)熱鍍(du)(du)(du)(du)鋅(xin)板不(bu)放輻射的。空調(diao)，冰(bing)箱(xiang)，微波爐及(ji)其類似家電(dian)(dian)背面的那個板就是熱鍍(du)(du)(du)(du)鋅(xin)板。鍍(du)(du)(du)(du)鋅(xin)層(ceng)通(tong)過(guo)(guo)鈍(dun)化(hua)處理，可(ke)(ke)減少潮溫貯運條(tiao)件下產生折(zhe)銹(xiu)蝕(白銹(xiu)) 。但這(zhe)種(zhong)化(hua)學處理的防腐蝕性(xing)能是有限的，而且，妨(fang)礙大多數涂料(liao)的附著性(xing)。這(zhe)種(zhong)處理一般不(bu)用(yong)(yong)(yong)(yong)在鋅(xin)鐵合金鍍(du)(du)(du)(du)層(ceng)，除光整表(biao)面外，作為(wei)常規，生產廠(chang)對(dui)其他類型(xing)的鍍(du)(du)(du)(du)鋅(xin)層(ceng)均進行鈍(dun)化(hua)處理。

首先，在鋼結構樓層板中要達到耐火1.5小時，總的來說可以選擇開口板、縮口板、閉口板三大類。孝感鍍鋅鋼規范上混凝土要高于開口板肋頂之上80mm，并且板底需配置板底受力筋。還有一種就是再開口板底部刷防火涂料，涂料厚度大于等于15,這樣的話，只要達到構造要求高于肋頂5公分就可以了。鍍鋅鋼批發而縮口(kou)板和閉口(kou)板，只需(xu)(xu)要總的樓(lou)板厚度大于(yu)等于(yu)110即可，但是縮口(kou)板雖(sui)然(ran)在防火(huo)方面(mian)比開(kai)口(kou)板要好。但是底(di)部還是需(xu)(xu)要加板底(di)受(shou)力筋，而閉口(kou)板則(ze)不需(xu)(xu)要。

鍍鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)按(an)用(yong)(yong)(yong)(yong)途又可分(fen)為一般(ban)用(yong)(yong)(yong)(yong)、屋(wu)頂(ding)用(yong)(yong)(yong)(yong)、建(jian)筑外側板(ban)(ban)(ban)用(yong)(yong)(yong)(yong)、結(jie)構用(yong)(yong)(yong)(yong)、瓦壟板(ban)(ban)(ban)用(yong)(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)(yong)和深沖用(yong)(yong)(yong)(yong)等鍍鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。對(dui)于一般(ban)防保(bao)護用(yong)(yong)(yong)(yong)鍍層，可以(yi)采(cai)用(yong)(yong)(yong)(yong)堿性鋅(xin)(xin)(xin)酸鹽鍍鋅(xin)(xin)(xin)彩色鈍化工(gong)(gong)藝。有時(shi)為了產品的(de)配(pei)色需(xu)要，也可以(yi)采(cai)用(yong)(yong)(yong)(yong)藍白色鈍化工(gong)(gong)藝，比如軍綠色鈍化、黑色鈍化等。為提高鋼(gang)管(guan)(guan)的(de)耐腐蝕性能，對(dui)一般(ban)鋼(gang)管(guan)(guan)進行(xing)(xing)鍍鋅(xin)(xin)(xin)。鍍鋅(xin)(xin)(xin)卷分(fen)熱鍍鋅(xin)(xin)(xin)和電(dian)鍍鋅(xin)(xin)(xin)兩(liang)種(zhong)，熱鍍鋅(xin)(xin)(xin)鍍鋅(xin)(xin)(xin)層厚(hou)，電(dian)鍍鋅(xin)(xin)(xin)成(cheng)本低，表面(mian)不是(shi)很(hen)光滑。吹(chui)氧(yang)焊管(guan)(guan)：用(yong)(yong)(yong)(yong)作(zuo)煉鋼(gang)吹(chui)氧(yang)用(yong)(yong)(yong)(yong)管(guan)(guan)，一般(ban)用(yong)(yong)(yong)(yong)小口(kou)徑的(de)焊接(jie)鋼(gang)管(guan)(guan)，規格(ge)由3/8-2寸八種(zhong)。用(yong)(yong)(yong)(yong)08、10、15、20或者195-Q235的(de)鋼(gang)帶制作(zuo)成(cheng)的(de)，為了防腐蝕，有得進行(xing)(xing)滲鋁處理。鍍鋅(xin)(xin)(xin)其防護作(zuo)用(yong)(yong)(yong)(yong)更強(qiang)，抗腐蝕能力強(qiang)。整個結(jie)構由鋅(xin)(xin)(xin)，形(xing)成(cheng)致密的(de)四元結(jie)晶體，此結(jie)晶體在鋼(gang)板(ban)(ban)(ban)上形(xing)成(cheng)一層屏障， 因而有效的(de)防止腐蝕因子穿(chuan)透。 耐腐蝕性來自鋅(xin)(xin)(xin)的(de)障礙層保(bao)護功能強(qiang)。

熱鍍(du)鋅(xin)(xin)卷板現貨消(xiao)息：熱鍍(du)鋅(xin)(xin)產(chan)(chan)品廣泛用(yong)于建筑、家(jia)電、車船(chuan)、容器制(zhi)造(zao)業、機電業等，幾乎涉及到(dao)衣食住(zhu)行各個領域(yu)。近年來(lai)，世(shi)界鍍(du)鋅(xin)(xin)鋼(gang)(gang)板需求量不斷增(zeng)加，產(chan)(chan)量增(zeng)長也很快，在美、日等鋼(gang)(gang)材(cai)生產(chan)(chan)大國，熱鍍(du)鋅(xin)(xin)鋼(gang)(gang)板在鋼(gang)(gang)材(cai)中(zhong)所占比(bi)例已高達13%-15%。 熱鍍(du)鋅(xin)(xin)卷板現貨消(xiao)息：近來(lai)，汽車行業越來(lai)越重(zhong)視(shi)材(cai)料的使(shi)用(yong)壽命，用(yong)涂漆冷軋鋼(gang)(gang)板已不能滿足耐腐(fu)蝕方面(mian)的要求。在這(zhe)種情(qing)況下，耐腐(fu)蝕性優良(liang)且成(cheng)本低廉的熱鍍(du)鋅(xin)(xin)板開始普遍受到(dao)了汽車廠家(jia)的青(qing)睞。
