彩涂卷哪家好規格

   彩涂卷是以把有機涂料涂復在熱鍍鋅鋼板上得到的產品即為熱鍍鋅彩涂板。熱鍍鋅彩涂板除具有鋅的保護作用外，表面上的有機涂層還起了隔絕保護、防止生銹的作用，使用壽命比熱鍍鋅板更長。熱(re)鍍(du)鋅(xin)基板(ban)的含鋅(xin)量一般為180g/m2（雙面(mian)），建(jian)筑(zhu)外(wai)用熱(re)鍍(du)鋅(xin)基板(ban)的鍍(du)鋅(xin)量高為275g/m2。，在表(biao)面(mian)涂敷一層或幾(ji)層有(you)機涂料(liao)，隨后經(jing)過烘烤固化而成的產(chan)品。也因(yin)涂有(you)各種(zhong)不同(tong)顏色(se)的有(you)機涂料(liao)彩色(se)鋼卷板(ban)由此得名，簡稱彩涂卷。

    使用(yong)鍍(du)鋅鋼(gang)板(ban)(ban)(ban)(ban)為基板(ban)(ban)(ban)(ban)的(de)彩(cai)色涂(tu)(tu)(tu)層(ceng)(ceng)鋼(gang)板(ban)(ban)(ban)(ban)，除有鋅保護外，鋅層(ceng)(ceng)上(shang)的(de)有機涂(tu)(tu)(tu)層(ceng)(ceng)起了覆蓋隔(ge)離作用(yong)，可防止(zhi)鋼(gang)板(ban)(ban)(ban)(ban)生銹，使用(yong)壽(shou)命比鍍(du)鋅鋼(gang)板(ban)(ban)(ban)(ban)更長，據介紹涂(tu)(tu)(tu)層(ceng)(ceng)鋼(gang)板(ban)(ban)(ban)(ban)的(de)使用(yong)壽(shou)命比鍍(du)鋅鋼(gang)板(ban)(ban)(ban)(ban)長50%。 但是，在(zai)不(bu)(bu)同(tong)(tong)的(de)地(di)區和(he)不(bu)(bu)同(tong)(tong)的(de)使用(yong)部位，采(cai)用(yong)相同(tong)(tong)鍍(du)鋅量、同(tong)(tong)種涂(tu)(tu)(tu)料(liao)、相同(tong)(tong)涂(tu)(tu)(tu)層(ceng)(ceng)厚度(du)的(de)彩(cai)色涂(tu)(tu)(tu)層(ceng)(ceng)板(ban)(ban)(ban)(ban)，其(qi)使用(yong)壽(shou)命會有很大的(de)不(bu)(bu)同(tong)(tong)。
