鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)帶鋼(gang)的(de)(de)(de)鋅(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)特性 電鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)是不能形(xing)成鋅(xin)(xin)(xin)(xin)(xin)(xin)花(hua)的(de)(de)(de)，熱鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)則(ze)有鋅(xin)(xin)(xin)(xin)(xin)(xin)花(hua)，其形(xing)成過程如下：當鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)帶從(cong)鋅(xin)(xin)(xin)(xin)(xin)(xin)鍋(guo)出來后(hou)，經氣刀的(de)(de)(de)噴吹，大量(liang)鋅(xin)(xin)(xin)(xin)(xin)(xin)液(ye)被(bei)吹回鋅(xin)(xin)(xin)(xin)(xin)(xin)鍋(guo)，這(zhe)時帶鋼(gang)表(biao)面還有純鋅(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)，呈液(ye) 態(tai)附在鋼(gang)板表(biao)面，在鋼(gang)板表(biao)面形(xing)成大量(liang)結(jie)晶(jing)核，隨著(zhu)鋼(gang)板上升冷(leng)卻(que)，使(shi)結(jie)晶(jing)核慢慢長成鋅(xin)(xin)(xin)(xin)(xin)(xin)花(hua)。冷(leng)卻(que)速度越快鋅(xin)(xin)(xin)(xin)(xin)(xin)花(hua)越小，冷(leng)卻(que)速度越慢鋅(xin)(xin)(xin)(xin)(xin)(xin)花(hua)越大。熱鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)帶鋼(gang)在我國市場一直是緊缺品種。從(cong)20世紀90年代中期以來，每年都要從(cong)國外進口(kou)80-100萬t左右。隨著(zhu)國內經濟的(de)(de)(de)發展，尤其是汽車、家(jia)電及(ji)建筑(zhu)業的(de)(de)(de)發展，對(dui)鍍(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)帶鋼(gang)的(de)(de)(de)需求(qiu)量(liang)也大大增加。

鍍鋁鋅板廠家鍍鋅鋼板為基板的彩涂鋼板，除有鋅保護外，鋅層上的有機涂層起了覆蓋隔離作用，可防止鋼板生銹，使用壽命比鍍鋅鋼板更長，據介紹涂層鋼板的使用壽命比鍍鋅鋼板長50%。眉山鍍鋁鋅板在連續機組上以冷(leng)軋帶鋼(gang)(gang)，鍍(du)鋅(xin)帶鋼(gang)(gang)（電鍍(du)鋅(xin)和熱鍍(du)鋅(xin)）為(wei)基板(ban)(ban)，經過(guo)表(biao)面預(yu)處理(li)（脫脂和化學(xue)處理(li)），用(yong)輥涂的(de)方法，涂上一(yi)層(ceng)(ceng)或多層(ceng)(ceng)液態涂料(liao)，經過(guo)烘烤和冷(leng)卻所得的(de)板(ban)(ban)材即為(wei)涂層(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)。由于涂層(ceng)(ceng)可以有(you)各種不(bu)同的(de)顏色，習慣上把涂層(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)叫(jiao)做彩色涂層(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)。又由于涂層(ceng)(ceng)是(shi)在鋼(gang)(gang)板(ban)(ban)成型加工之(zhi)前(qian)進行的(de)，在國外這叫(jiao)做預(yu)涂層(ceng)(ceng)鋼(gang)(gang)板(ban)(ban)。

重慶鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)按生產及加工方法可(ke)分為以下(xia)幾類： 熱浸(jin)(jin)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)。將薄鋼(gang)板(ban)(ban)(ban)浸(jin)(jin)入熔解(jie)(jie)的(de)(de)鋅(xin)(xin)槽中(zhong)，使其表面粘附一(yi)層鋅(xin)(xin)的(de)(de)薄鋼(gang)板(ban)(ban)(ban)。目前主要采用(yong)(yong)連續鍍(du)(du)(du)鋅(xin)(xin)工藝(yi)生產，即(ji)把成卷的(de)(de)鋼(gang)板(ban)(ban)(ban)連續浸(jin)(jin)在熔解(jie)(jie)有(you)鋅(xin)(xin)的(de)(de)鍍(du)(du)(du)槽中(zhong)制(zhi)(zhi)成鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)； 合金(jin)化鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)。為克服單面未涂(tu)鋅(xin)(xin)的(de)(de)缺點，又(you)有(you)一(yi)種(zhong)在另面涂(tu)以薄層鋅(xin)(xin)的(de)(de)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)，即(ji)雙面差鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)；合金(jin)、復合鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)。它是用(yong)(yong)鋅(xin)(xin)和(he)其他金(jin)屬如鉛、鋅(xin)(xin)制(zhi)(zhi)成合金(jin)乃至(zhi)復合鍍(du)(du)(du)成的(de)(de)鋼(gang)板(ban)(ban)(ban)。這種(zhong)鋼(gang)板(ban)(ban)(ban)既具有(you)防銹(xiu)性(xing)能，又(you)有(you)良好的(de)(de)涂(tu)裝性(xing)能。
