彩(cai)涂(tu)板，業(ye)(ye)內又稱彩(cai)鋼(gang)(gang)板，彩(cai)板。彩(cai)色涂(tu)層(ceng)鋼(gang)(gang)板是以(yi)冷軋鋼(gang)(gang)板和鍍鋅鋼(gang)(gang)板為基板，經(jing)過(guo)表面預處理（脫(tuo)脂(zhi)、清洗、化(hua)學轉化(hua)處理），以(yi)連續的(de)方法涂(tu)上涂(tu)料（輥涂(tu)法），經(jing)過(guo)烘烤和冷卻而制成的(de)產品。涂(tu)層(ceng)鋼(gang)(gang)板具(ju)有輕質、美觀和良好的(de)防腐蝕性(xing)能(neng)，又可直接加工，它給建筑(zhu)業(ye)(ye)、造(zao)船業(ye)(ye)、車輛制造(zao)業(ye)(ye)、家具(ju)行業(ye)(ye)、電氣行業(ye)(ye)等提供了(le)一(yi)種新型原(yuan)材料，起到了(le)以(yi)鋼(gang)(gang)代木、高效施(shi)工、節約能(neng)源、防止污染等良好效果。

彩(cai)涂(tu)板基本概(gai)念：在連續機組上(shang)以冷(leng)軋帶鋼(gang)，鍍(du)鋅帶鋼(gang)（電鍍(du)鋅和(he)熱鍍(du)鋅）為基板，經(jing)(jing)過(guo)表面(mian)預處(chu)理（脫脂和(he)化學處(chu)理），用輥涂(tu)的(de)方法，涂(tu)上(shang)一層(ceng)(ceng)(ceng)或多層(ceng)(ceng)(ceng)液(ye)態涂(tu)料，經(jing)(jing)過(guo)烘烤和(he)冷(leng)卻所得的(de)板材即為涂(tu)層(ceng)(ceng)(ceng)鋼(gang)板。國(guo)內(nei)有背(bei)（底）漆(qi)(qi)(qi)和(he)面(mian)（正面(mian)）漆(qi)(qi)(qi)涂(tu)層(ceng)(ceng)(ceng)，一般國(guo)內(nei)是背(bei)漆(qi)(qi)(qi)一層(ceng)(ceng)(ceng)，面(mian)漆(qi)(qi)(qi)兩層(ceng)(ceng)(ceng)，國(guo)外業務面(mian)漆(qi)(qi)(qi)背(bei)漆(qi)(qi)(qi)均是兩層(ceng)(ceng)(ceng)。由于涂(tu)層(ceng)(ceng)(ceng)可以有各種(zhong)不(bu)同(tong)的(de)顏色，習慣上(shang)把(ba)涂(tu)層(ceng)(ceng)(ceng)鋼(gang)板叫做彩(cai)色涂(tu)層(ceng)(ceng)(ceng)鋼(gang)板。

產(chan)品用途

使(shi)用(yong)(yong)(yong)(yong)(yong)鍍(du)鋅(xin)(xin)鋼(gang)板為基(ji)板的(de)(de)(de)彩色涂(tu)(tu)層(ceng)鋼(gang)板，除(chu)有鋅(xin)(xin)保護外，鋅(xin)(xin)層(ceng)上(shang)的(de)(de)(de)有機涂(tu)(tu)層(ceng)起(qi)了(le)覆(fu)蓋隔離作用(yong)(yong)(yong)(yong)(yong)，可防止(zhi)鋼(gang)板生銹，使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)(shou)命(ming)(ming)(ming)比鍍(du)鋅(xin)(xin)鋼(gang)板更長(chang)，據介紹涂(tu)(tu)層(ceng)鋼(gang)板的(de)(de)(de)使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)(shou)命(ming)(ming)(ming)比鍍(du)鋅(xin)(xin)鋼(gang)板長(chang)50%。但是，在(zai)不(bu)同的(de)(de)(de)地區(qu)和不(bu)同的(de)(de)(de)使(shi)用(yong)(yong)(yong)(yong)(yong)部(bu)位，采用(yong)(yong)(yong)(yong)(yong)相同鍍(du)鋅(xin)(xin)量、同種涂(tu)(tu)料、相同涂(tu)(tu)層(ceng)厚度的(de)(de)(de)彩色涂(tu)(tu)層(ceng)板，其使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)(shou)命(ming)(ming)(ming)會有很大的(de)(de)(de)不(bu)同。例如，在(zai)工(gong)業區(qu)或(huo)(huo)沿(yan)海地區(qu)，由(you)于(yu)受(shou)到空(kong)氣中二氧化硫氣體(ti)或(huo)(huo)鹽分的(de)(de)(de)作用(yong)(yong)(yong)(yong)(yong)，腐蝕速度加(jia)快(kuai)，使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)(shou)命(ming)(ming)(ming)受(shou)到影(ying)(ying)響。在(zai)雨季(ji)，涂(tu)(tu)層(ceng)長(chang)期(qi)受(shou)雨水浸濕、或(huo)(huo)者在(zai)日夜溫差太大易結露(lu)的(de)(de)(de)部(bu)位，都會較快(kuai)地受(shou)到腐蝕，使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)(shou)命(ming)(ming)(ming)均(jun)會降低。用(yong)(yong)(yong)(yong)(yong)彩色涂(tu)(tu)層(ceng)鋼(gang)板制造的(de)(de)(de)建筑物(wu)或(huo)(huo)廠房，經常受(shou)到雨水沖(chong)洗時(shi)(shi)使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)(shou)命(ming)(ming)(ming)較長(chang)，否則(ze)，由(you)于(yu)受(shou)二氧化硫氣體(ti)、鹽和灰塵的(de)(de)(de)作用(yong)(yong)(yong)(yong)(yong)而影(ying)(ying)響使(shi)用(yong)(yong)(yong)(yong)(yong)。因此，在(zai)設計時(shi)(shi)，若屋頂的(de)(de)(de)傾斜度越(yue)(yue)大，則(ze)越(yue)(yue)不(bu)容易積(ji)聚灰塵等(deng)污物(wu)，使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)(shou)命(ming)(ming)(ming)越(yue)(yue)長(chang)；對(dui)于(yu)那些(xie)不(bu)受(shou)雨水經常沖(chong)洗的(de)(de)(de)區(qu)域(yu)或(huo)(huo)部(bu)位，應定期(qi)用(yong)(yong)(yong)(yong)(yong)水沖(chong)洗。家(jia)電：31%建筑：63%其他：6%，彩鋼板應(ying)用比較廣泛(fan)。具有無污染(ran)、優秀的耐候性、抗(kang)腐蝕(shi)、高加(jia)工等特性。彩鋼板廣泛(fan)應(ying)用于(yu)建筑、家(jia)電、運(yun)輸、包裝、機(ji)械加(jia)工、室內(nei)裝修、醫療、汽車工業等。
