鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)是(shi)(shi)電鍍(du)或熱(re)鍍(du)一(yi)層(ceng)(ceng)約5~12μm金屬鋅(xin)(xin)的(de)鋼(gang)板(ban)(ban)(ban)(ban)。為防(fang)止鋼(gang)板(ban)(ban)(ban)(ban)表(biao)(biao)面(mian)遭受腐蝕(shi)，延長(chang)(chang)其(qi)使(shi)用(yong)(yong)(yong)壽命，在鋼(gang)板(ban)(ban)(ban)(ban)表(biao)(biao)面(mian)涂(tu)以一(yi)層(ceng)(ceng)金屬鋅(xin)(xin)，這種(zhong)涂(tu)鋅(xin)(xin)的(de)鋼(gang)板(ban)(ban)(ban)(ban)稱為鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)或鍍(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)廣泛用(yong)(yong)(yong)于建筑、輕(qing)工(gong)、汽(qi)車(che)、家電、電子、農牧(mu)漁業(ye)、商品包(bao)裝等行(xing)業(ye)。近幾年(nian)，我國建筑、家電等行(xing)業(ye)對(dui)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)需(xu)(xu)求增(zeng)長(chang)(chang)很快，市場潛力較(jiao)大，尤(you)其(qi)是(shi)(shi)近年(nian)來隨著建筑輕(qing)型結構的(de)迅速發展，轎車(che)產(chan)(chan)量的(de)逐(zhu)年(nian)增(zeng)加(jia)，家用(yong)(yong)(yong)電器的(de)普(pu)及，合資(zi)、獨資(zi)企業(ye)電子產(chan)(chan)品的(de)大量出口，使(shi)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)的(de)消(xiao)費量增(zeng)長(chang)(chang)較(jiao)快。按生產(chan)(chan)方式鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)分為熱(re)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)和電鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)。目前國內(nei)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)的(de)生產(chan)(chan)無論是(shi)(shi)數量還是(shi)(shi)品種(zhong)均不(bu)能(neng)滿足市場需(xu)(xu)求，每年(nian)需(xu)(xu)要大量進口，國內(nei)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)生產(chan)(chan)市場占有率較(jiao)低，國內(nei)市場供不(bu)應求，市場潛力巨大。鍍(du)鋅(xin)(xin)風(feng)管是(shi)(shi)早使(shi)用(yong)(yong)(yong)的(de)風(feng)管材(cai)料(liao)之一(yi)，采用(yong)(yong)(yong)鍍(du)鋅(xin)(xin)鐵皮加(jia)工(gong)而成，適用(yong)(yong)(yong)于含(han)濕量小的(de)一(yi)般(ban)性氣體的(de)輸送(song)，是(shi)(shi)目前消(xiao)防(fang)工(gong)程中防(fang)排煙工(gong)程中的(de)首選(xuan)。
