彩涂卷哪家好哪家好

   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(chang)。熱鍍(du)(du)(du)鋅(xin)基(ji)板(ban)的(de)含(han)鋅(xin)量一般(ban)為180g/m2（雙面(mian)），建筑(zhu)外用熱鍍(du)(du)(du)鋅(xin)基(ji)板(ban)的(de)鍍(du)(du)(du)鋅(xin)量高為275g/m2。，在表面(mian)涂(tu)(tu)敷(fu)一層或幾層有(you)機涂(tu)(tu)料，隨后經過烘烤固化(hua)而成(cheng)的(de)產(chan)品。也因涂(tu)(tu)有(you)各(ge)種不同顏色的(de)有(you)機涂(tu)(tu)料彩色鋼卷板(ban)由此得名，簡(jian)稱彩涂(tu)(tu)卷。

    使(shi)(shi)用(yong)(yong)鍍(du)鋅鋼(gang)板(ban)(ban)為(wei)基板(ban)(ban)的(de)彩(cai)色(se)涂層(ceng)鋼(gang)板(ban)(ban)，除(chu)有(you)鋅保護外，鋅層(ceng)上的(de)有(you)機涂層(ceng)起(qi)了覆蓋隔離作用(yong)(yong)，可防止鋼(gang)板(ban)(ban)生銹，使(shi)(shi)用(yong)(yong)壽命比鍍(du)鋅鋼(gang)板(ban)(ban)更長，據介紹(shao)涂層(ceng)鋼(gang)板(ban)(ban)的(de)使(shi)(shi)用(yong)(yong)壽命比鍍(du)鋅鋼(gang)板(ban)(ban)長50%。 但(dan)是，在不同(tong)(tong)(tong)的(de)地區和(he)不同(tong)(tong)(tong)的(de)使(shi)(shi)用(yong)(yong)部位，采用(yong)(yong)相同(tong)(tong)(tong)鍍(du)鋅量、同(tong)(tong)(tong)種涂料(liao)、相同(tong)(tong)(tong)涂層(ceng)厚度(du)的(de)彩(cai)色(se)涂層(ceng)板(ban)(ban)，其(qi)使(shi)(shi)用(yong)(yong)壽命會有(you)很大的(de)不同(tong)(tong)(tong)。
