鍍(du)鋅(xin)板的分(fen)類和用途(tu)
按生產(chan)及加工(gong)方(fang)(fang)法(fa)可(ke)分為(wei)以(yi)下(xia)幾類：①熱浸(jin)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。將薄鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)浸(jin)入熔解(jie)的(de)(de)鋅(xin)(xin)(xin)(xin)槽中(zhong)，使其(qi)表面(mian)(mian)粘附一層(ceng)鋅(xin)(xin)(xin)(xin)的(de)(de)薄鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。目(mu)前主要采用(yong)連續鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)工(gong)藝生產(chan)，即(ji)把成卷的(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)連續浸(jin)在(zai)(zai)熔解(jie)有(you)(you)鋅(xin)(xin)(xin)(xin)的(de)(de)鍍(du)(du)(du)(du)(du)槽中(zhong)制(zhi)成鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban);②合(he)金(jin)化(hua)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)也(ye)是用(yong)熱浸(jin)法(fa)制(zhi)造(zao)，但(dan)在(zai)(zai)出槽后，立(li)即(ji)把它加熱到500 ℃左右，使其(qi)生成鋅(xin)(xin)(xin)(xin)和(he)鐵的(de)(de)合(he)金(jin)被(bei)膜(mo)。這(zhe)種鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)具(ju)有(you)(you)良(liang)好(hao)的(de)(de)涂料的(de)(de)密著性(xing)和(he)焊接性(xing);③電鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。用(yong)電鍍(du)(du)(du)(du)(du)法(fa)制(zhi)造(zao)這(zhe)種鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)具(ju)有(you)(you)良(liang)好(hao)的(de)(de)加工(gong)性(xing)。但(dan)鍍(du)(du)(du)(du)(du)層(ceng)較薄，耐(nai)腐蝕(shi)性(xing)不如(ru)熱浸(jin)法(fa)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban);④單面(mian)(mian)鍍(du)(du)(du)(du)(du)和(he)雙面(mian)(mian)差(cha)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。單面(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，即(ji)只在(zai)(zai)一面(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)的(de)(de)產(chan)品。在(zai)(zai)焊接、涂裝、防(fang)銹處理、加工(gong)等方(fang)(fang)面(mian)(mian)，具(ju)有(you)(you)比雙面(mian)(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)更(geng)好(hao)的(de)(de)適應性(xing)。為(wei)克服單面(mian)(mian)未涂鋅(xin)(xin)(xin)(xin)的(de)(de)缺(que)點，又有(you)(you)一種在(zai)(zai)另面(mian)(mian)涂以(yi)薄層(ceng)鋅(xin)(xin)(xin)(xin)的(de)(de)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)，即(ji)雙面(mian)(mian)差(cha)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)(ban)(ban);⑤合(he) 金(jin)、復合(he)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。它是用(yong)鋅(xin)(xin)(xin)(xin)和(he)其(qi)他金(jin)屬(shu)如(ru)鉛(qian)、鋅(xin)(xin)(xin)(xin)制(zhi)成合(he)金(jin)乃至復合(he)鍍(du)(du)(du)(du)(du)成的(de)(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)既具(ju)有(you)(you)卓越的(de)(de)防(fang)銹性(xing)能，又有(you)(you)良(liang)好(hao)的(de)(de)涂裝性(xing)能。
除上述五種外，還有彩色鍍(du)鋅(xin)鋼板(ban)、印花涂裝(zhuang)鍍(du)鋅(xin)鋼板(ban)、聚氯乙烯疊層鍍(du)鋅(xin)鋼板(ban)等(deng)。但(dan)目前(qian)最常用(yong)的(de)仍為熱浸鍍(du)鋅(xin)板(ban)。
鍍鋅鋼(gang)板(ban)(ban)按用(yong)(yong)(yong)(yong)途又可分為(wei)一(yi)般用(yong)(yong)(yong)(yong)、屋頂(ding)用(yong)(yong)(yong)(yong)、建筑外(wai)側板(ban)(ban)用(yong)(yong)(yong)(yong)、結構用(yong)(yong)(yong)(yong)、瓦壟板(ban)(ban)用(yong)(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)(yong)和深沖用(yong)(yong)(yong)(yong)等鍍鋅鋼(gang)板(ban)(ban)。
