鍍鋅價格熱鍍鋅板和電鍍鋅板在鍍鋅量上有很大的差別，就像山東彩涂卷）。熱鍍鋅的鍍鋅量不可能太小，一般較小為雙面50～60g／m2，較大可達600g／m2。江津鍍鋅電鍍(du)鋅(xin)(xin)板的(de)鍍(du)鋅(xin)(xin)層可(ke)以很(hen)薄，較小(xiao)達15g／m2，但要求鍍(du)層較厚的(de)話則(ze)生產線速度很(hen)慢，不適應現代化機(ji)組的(de)工藝特點(dian)，一(yi)般(ban)(ban)較大為(wei)lO0g／m2左右。正因為(wei)如此，電鍍(du)鋅(xin)(xin)板的(de)生產受到很(hen)大的(de)限制。工一(yi)般(ban)(ban)電鍍(du)鋅(xin)(xin)比較多，適用于(yu)小(xiao)部(bu)件；熱(re)鍍(du)鋅(xin)(xin)一(yi)般(ban)(ban)用于(yu)電力設備和構(gou)件，適用于(yu)大的(de)部(bu)件和設備。當(dang)然他們的(de)價格也相對便宜一(yi)些。建設部(bu)已正式下文，淘(tao)汰技術落后(hou)的(de)冷鍍(du)鋅(xin)(xin)管，不準用冷鍍(du)鋅(xin)(xin)管作水、煤氣管。

鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)帶鋼(gang)(gang)(gang)的(de)鋅(xin)(xin)(xin)(xin)層特性 電鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)層是不(bu)能形(xing)成鋅(xin)(xin)(xin)(xin)花(hua)(hua)的(de)，熱鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)層則有(you)鋅(xin)(xin)(xin)(xin)花(hua)(hua)，其形(xing)成過程如(ru)下(xia)：當(dang)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)帶從(cong)(cong)鋅(xin)(xin)(xin)(xin)鍋出來后，經氣刀的(de)噴吹(chui)，大量(liang)鋅(xin)(xin)(xin)(xin)液被吹(chui)回鋅(xin)(xin)(xin)(xin)鍋，這時帶鋼(gang)(gang)(gang)表(biao)(biao)面還有(you)純鋅(xin)(xin)(xin)(xin)層，呈液 態附在鋼(gang)(gang)(gang)板(ban)表(biao)(biao)面，在鋼(gang)(gang)(gang)板(ban)表(biao)(biao)面形(xing)成大量(liang)結晶核，隨著鋼(gang)(gang)(gang)板(ban)上(shang)升冷卻，使結晶核慢慢長成鋅(xin)(xin)(xin)(xin)花(hua)(hua)。冷卻速度越(yue)快鋅(xin)(xin)(xin)(xin)花(hua)(hua)越(yue)小，冷卻速度越(yue)慢鋅(xin)(xin)(xin)(xin)花(hua)(hua)越(yue)大。熱鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)帶鋼(gang)(gang)(gang)在我國(guo)市場(chang)一直(zhi)是緊缺品種(zhong)。從(cong)(cong)20世紀90年(nian)代中(zhong)期以來，每年(nian)都要(yao)從(cong)(cong)國(guo)外進口80-100萬t左右。隨著國(guo)內經濟的(de)發(fa)展(zhan)，尤其是汽車、家電及建筑業的(de)發(fa)展(zhan)，對鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)帶鋼(gang)(gang)(gang)的(de)需(xu)求(qiu)量(liang)也大大增加(jia)。
