彩涂卷哪家好專賣

   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)(du)鋅(xin)基板(ban)的(de)含鋅(xin)量(liang)一般為(wei)180g/m2（雙面），建筑外用熱(re)鍍(du)(du)鋅(xin)基板(ban)的(de)鍍(du)(du)鋅(xin)量(liang)高為(wei)275g/m2。，在表面涂(tu)敷(fu)一層或幾層有機(ji)涂(tu)料(liao)，隨后經過烘(hong)烤固化(hua)而成的(de)產品。也因涂(tu)有各種不同顏色(se)的(de)有機(ji)涂(tu)料(liao)彩色(se)鋼(gang)卷(juan)板(ban)由此(ci)得(de)名，簡稱彩涂(tu)卷(juan)。

    使(shi)用(yong)(yong)鍍(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)為基板(ban)(ban)(ban)(ban)的彩色涂(tu)層(ceng)(ceng)鋼(gang)板(ban)(ban)(ban)(ban)，除有鋅(xin)保護外，鋅(xin)層(ceng)(ceng)上的有機涂(tu)層(ceng)(ceng)起了覆蓋(gai)隔離作用(yong)(yong)，可防止鋼(gang)板(ban)(ban)(ban)(ban)生銹，使(shi)用(yong)(yong)壽命(ming)(ming)比鍍(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)更長，據介紹涂(tu)層(ceng)(ceng)鋼(gang)板(ban)(ban)(ban)(ban)的使(shi)用(yong)(yong)壽命(ming)(ming)比鍍(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)長50%。 但(dan)是，在不(bu)同的地區和(he)不(bu)同的使(shi)用(yong)(yong)部位，采用(yong)(yong)相(xiang)同鍍(du)鋅(xin)量、同種涂(tu)料(liao)、相(xiang)同涂(tu)層(ceng)(ceng)厚度(du)的彩色涂(tu)層(ceng)(ceng)板(ban)(ban)(ban)(ban)，其(qi)使(shi)用(yong)(yong)壽命(ming)(ming)會有很(hen)大(da)的不(bu)同。
