鍍(du)鋅(xin)鋼板(ban)按用(yong)(yong)(yong)途(tu)又可分(fen)為(wei)一般用(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)、建(jian)筑外(wai)側板(ban)用(yong)(yong)(yong)、結構用(yong)(yong)(yong)、瓦壟板(ban)用(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)和深沖用(yong)(yong)(yong)等鍍(du)鋅(xin)鋼板(ban)。熱鍍(du)鋅(xin)板(ban)主要(yao)應用(yong)(yong)(yong)于建(jian)筑外(wai)用(yong)(yong)(yong)，建(jian)筑內用(yong)(yong)(yong)，民用(yong)(yong)(yong)，門窗，家(jia)具，機械，電子及(ji)家(jia)用(yong)(yong)(yong)電器等領域。也(ye)有機箱用(yong)(yong)(yong)這(zhe)個(ge)(ge)，不過熱鍍(du)鋅(xin)板(ban)不放輻(fu)射的(de)(de)(de)。空調，冰箱，微波爐及(ji)其類(lei)似(si)家(jia)電背(bei)面(mian)的(de)(de)(de)那個(ge)(ge)板(ban)就是熱鍍(du)鋅(xin)板(ban)。鍍(du)鋅(xin)層(ceng)(ceng)通過鈍(dun)化處(chu)理(li)(li)(li)，可減少(shao)潮溫(wen)貯運條(tiao)件下產生折銹蝕(白銹) 。但這(zhe)種化學處(chu)理(li)(li)(li)的(de)(de)(de)防(fang)腐蝕性(xing)能是有限(xian)的(de)(de)(de)，而且，妨礙大(da)多數涂(tu)料的(de)(de)(de)附著性(xing)。這(zhe)種處(chu)理(li)(li)(li)一般不用(yong)(yong)(yong)在鋅(xin)鐵合金鍍(du)層(ceng)(ceng)，除光(guang)整表面(mian)外(wai)，作為(wei)常(chang)規，生產廠對其他(ta)類(lei)型的(de)(de)(de)鍍(du)鋅(xin)層(ceng)(ceng)均(jun)進行鈍(dun)化處(chu)理(li)(li)(li)。

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(suo)口(kou)(kou)板(ban)(ban)(ban)和閉口(kou)(kou)板(ban)(ban)(ban)，只需(xu)要總的樓板(ban)(ban)(ban)厚(hou)度大于等于110即可，但是縮(suo)口(kou)(kou)板(ban)(ban)(ban)雖然在(zai)防火方面(mian)比開口(kou)(kou)板(ban)(ban)(ban)要好。但是底部(bu)還(huan)是需(xu)要加(jia)板(ban)(ban)(ban)底受力筋，而閉口(kou)(kou)板(ban)(ban)(ban)則不需(xu)要。

鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)按用(yong)(yong)(yong)途又可分為一(yi)般(ban)用(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)、建(jian)筑外(wai)側(ce)板(ban)用(yong)(yong)(yong)、結構用(yong)(yong)(yong)、瓦壟板(ban)用(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)和深沖用(yong)(yong)(yong)等鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)。對(dui)于(yu)一(yi)般(ban)防(fang)保護(hu)用(yong)(yong)(yong)鍍(du)(du)(du)層，可以采(cai)用(yong)(yong)(yong)堿(jian)性(xing)鋅(xin)(xin)(xin)(xin)酸鹽鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)彩色(se)(se)鈍化(hua)工(gong)藝(yi)。有(you)時為了產品(pin)的配色(se)(se)需要，也可以采(cai)用(yong)(yong)(yong)藍白色(se)(se)鈍化(hua)工(gong)藝(yi)，比如軍綠色(se)(se)鈍化(hua)、黑(hei)色(se)(se)鈍化(hua)等。為提高鋼(gang)(gang)管(guan)的耐腐蝕(shi)(shi)性(xing)能，對(dui)一(yi)般(ban)鋼(gang)(gang)管(guan)進行(xing)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)。鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)卷分熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)和電(dian)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)兩種，熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)層厚，電(dian)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)成(cheng)本低，表面不是很(hen)光(guang)滑。吹氧焊管(guan)：用(yong)(yong)(yong)作(zuo)煉鋼(gang)(gang)吹氧用(yong)(yong)(yong)管(guan)，一(yi)般(ban)用(yong)(yong)(yong)小口徑的焊接鋼(gang)(gang)管(guan)，規格由3/8-2寸八種。用(yong)(yong)(yong)08、10、15、20或者195-Q235的鋼(gang)(gang)帶制作(zuo)成(cheng)的，為了防(fang)腐蝕(shi)(shi)，有(you)得進行(xing)滲鋁處理(li)。鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)其防(fang)護(hu)作(zuo)用(yong)(yong)(yong)更(geng)強，抗腐蝕(shi)(shi)能力(li)強。整個結構由鋅(xin)(xin)(xin)(xin)，形成(cheng)致(zhi)密的四元結晶體，此結晶體在鋼(gang)(gang)板(ban)上形成(cheng)一(yi)層屏障(zhang)， 因(yin)而有(you)效的防(fang)止腐蝕(shi)(shi)因(yin)子穿透。 耐腐蝕(shi)(shi)性(xing)來自鋅(xin)(xin)(xin)(xin)的障(zhang)礙層保護(hu)功(gong)能強。

熱(re)鍍鋅(xin)(xin)卷板(ban)(ban)現(xian)(xian)貨消息(xi)：熱(re)鍍鋅(xin)(xin)產品(pin)廣(guang)泛用于建筑、家電、車(che)船、容器制(zhi)造業、機電業等，幾乎涉及到(dao)衣食住行各個(ge)領域。近(jin)年來(lai)，世界鍍鋅(xin)(xin)鋼(gang)板(ban)(ban)需求(qiu)量(liang)不斷(duan)增加(jia)，產量(liang)增長也很快，在(zai)(zai)美(mei)、日等鋼(gang)材生(sheng)產大國，熱(re)鍍鋅(xin)(xin)鋼(gang)板(ban)(ban)在(zai)(zai)鋼(gang)材中所占比例(li)已(yi)高達13%-15%。 熱(re)鍍鋅(xin)(xin)卷板(ban)(ban)現(xian)(xian)貨消息(xi)：近(jin)來(lai)，汽車(che)行業越(yue)(yue)來(lai)越(yue)(yue)重視材料的使用壽命，用涂漆(qi)冷軋鋼(gang)板(ban)(ban)已(yi)不能滿足(zu)耐腐(fu)蝕(shi)方面的要求(qiu)。在(zai)(zai)這種情(qing)況下(xia)，耐腐(fu)蝕(shi)性優良(liang)且成本低廉的熱(re)鍍鋅(xin)(xin)板(ban)(ban)開(kai)始(shi)普遍受(shou)到(dao)了汽車(che)廠(chang)家的青睞。
