冷軋板廠家鍍鋅鋼板按用途又可分為一般用、屋頂用、建筑外側板用、結構用、瓦壟板用、拉伸用和深沖用等鍍鋅鋼板。攀鋼冷軋板廠家熱(re)鍍鋅(xin)板(ban)(ban)主要應用(yong)(yong)(yong)于(yu)建(jian)筑外用(yong)(yong)(yong)，建(jian)筑內(nei)用(yong)(yong)(yong)，民(min)用(yong)(yong)(yong)，門窗(chuang)，家(jia)(jia)具，機械，電(dian)子及家(jia)(jia)用(yong)(yong)(yong)電(dian)器(qi)等領域。也有機箱用(yong)(yong)(yong)這個，不(bu)過(guo)熱(re)鍍鋅(xin)板(ban)(ban)不(bu)放輻射的。空調，冰箱，微波爐及其(qi)類(lei)似(si)家(jia)(jia)電(dian)背面(mian)的那(nei)個板(ban)(ban)就是熱(re)鍍鋅(xin)板(ban)(ban)。鍍鋅(xin)層通(tong)過(guo)鈍(dun)化處理(li)，可(ke)減(jian)少潮溫貯運(yun)條件(jian)下產(chan)生折銹蝕(白銹) 。但這種化學處理(li)的防腐蝕性能是有限的，而且，妨礙大多(duo)數涂料的附著(zhu)性。這種處理(li)一(yi)般不(bu)用(yong)(yong)(yong)在鋅(xin)鐵合(he)金鍍層，除光整(zheng)表(biao)面(mian)外，作為常(chang)規，生產(chan)廠對其(qi)他類(lei)型(xing)的鍍鋅(xin)層均(jun)進行鈍(dun)化處理(li)。

熱鍍(du)(du)鋅(xin)(xin)板和(he)電(dian)鍍(du)(du)鋅(xin)(xin)板在鍍(du)(du)鋅(xin)(xin)量上有很大(da)(da)(da)的(de)(de)(de)差別，就(jiu)像山東彩涂卷(juan)）。熱鍍(du)(du)鋅(xin)(xin)的(de)(de)(de)鍍(du)(du)鋅(xin)(xin)量不(bu)(bu)可能(neng)太小(xiao)(xiao)，一般(ban)較(jiao)(jiao)(jiao)小(xiao)(xiao)為(wei)雙面50～60g／m2，較(jiao)(jiao)(jiao)大(da)(da)(da)可達600g／m2。電(dian)鍍(du)(du)鋅(xin)(xin)板的(de)(de)(de)鍍(du)(du)鋅(xin)(xin)層可以很薄，較(jiao)(jiao)(jiao)小(xiao)(xiao)達15g／m2，但(dan)要求鍍(du)(du)層較(jiao)(jiao)(jiao)厚的(de)(de)(de)話則生產線速度很慢，不(bu)(bu)適應現代化(hua)機(ji)組的(de)(de)(de)工藝(yi)特點，一般(ban)較(jiao)(jiao)(jiao)大(da)(da)(da)為(wei)lO0g／m2左(zuo)右。正因(yin)為(wei)如此(ci)，電(dian)鍍(du)(du)鋅(xin)(xin)板的(de)(de)(de)生產受(shou)到很大(da)(da)(da)的(de)(de)(de)限制(zhi)。工一般(ban)電(dian)鍍(du)(du)鋅(xin)(xin)比(bi)較(jiao)(jiao)(jiao)多，適用于(yu)小(xiao)(xiao)部件(jian)；熱鍍(du)(du)鋅(xin)(xin)一般(ban)用于(yu)電(dian)力(li)設(she)備和(he)構件(jian)，適用于(yu)大(da)(da)(da)的(de)(de)(de)部件(jian)和(he)設(she)備。當然(ran)他們的(de)(de)(de)價(jia)格也相對便宜一些。建設(she)部已正式下文，淘汰技術落(luo)后的(de)(de)(de)冷鍍(du)(du)鋅(xin)(xin)管(guan)，不(bu)(bu)準用冷鍍(du)(du)鋅(xin)(xin)管(guan)作水、煤氣(qi)管(guan)。

熱(re)鍍(du)鋅卷(juan)(juan)板(ban)(ban)現貨(huo)消息：熱(re)鍍(du)鋅產品廣泛用(yong)于建筑、家電、車(che)(che)船、容器制造(zao)業、機電業等，幾乎(hu)涉及到衣食住行(xing)各個領(ling)域。近(jin)年來(lai)，世界鍍(du)鋅鋼板(ban)(ban)需求量不斷(duan)增加，產量增長也很快，在美、日等鋼材生產大國，熱(re)鍍(du)鋅鋼板(ban)(ban)在鋼材中(zhong)所(suo)占比例已(yi)高(gao)達13%-15%。 熱(re)鍍(du)鋅卷(juan)(juan)板(ban)(ban)現貨(huo)消息：近(jin)來(lai)，汽(qi)車(che)(che)行(xing)業越(yue)來(lai)越(yue)重視材料(liao)的(de)使用(yong)壽命，用(yong)涂漆冷軋(ya)鋼板(ban)(ban)已(yi)不能滿(man)足耐(nai)(nai)腐蝕(shi)方(fang)面的(de)要(yao)求。在這種情(qing)況下，耐(nai)(nai)腐蝕(shi)性(xing)優良且(qie)成本(ben)低廉(lian)的(de)熱(re)鍍(du)鋅板(ban)(ban)開始(shi)普遍受到了(le)汽(qi)車(che)(che)廠(chang)家的(de)青睞(lai)。
