長春彩涂卷板

彩涂卷板是以熱鍍鋅板、熱鍍鋁鋅板、電鍍鋅板等為基板，經表面預處理（化學脫脂及化學轉化處理）之后，在表面涂敷一層或幾層有機涂料，隨后經過烘烤固化而成的產品。也因涂有各種不同顏色的有機涂料彩色鋼卷板由此得名，簡稱彩涂卷。

使用鍍鋅鋼板為(wei)基板(ban)的(de)(de)彩色涂(tu)層(ceng)鋼(gang)板(ban)，除有(you)鋅(xin)(xin)保護(hu)外，鋅(xin)(xin)層(ceng)上的(de)(de)有(you)機涂(tu)層(ceng)起了覆蓋隔(ge)離作用(yong)，可防止鋼(gang)板(ban)生銹，使(shi)(shi)用(yong)壽命(ming)比鍍鋅(xin)(xin)鋼(gang)板(ban)更長，據介紹涂(tu)層(ceng)鋼(gang)板(ban)的(de)(de)使(shi)(shi)用(yong)壽命(ming)比鍍鋅(xin)(xin)鋼(gang)板(ban)長50%。 但(dan)是，在不(bu)同(tong)(tong)(tong)的(de)(de)地區和不(bu)同(tong)(tong)(tong)的(de)(de)使(shi)(shi)用(yong)部位，采用(yong)相同(tong)(tong)(tong)鍍鋅(xin)(xin)量、同(tong)(tong)(tong)種涂(tu)料、相同(tong)(tong)(tong)涂(tu)層(ceng)厚(hou)度的(de)(de)彩色涂(tu)層(ceng)板(ban)，其使(shi)(shi)用(yong)壽命(ming)會有(you)很大的(de)(de)不(bu)同(tong)(tong)(tong)。
