沈陽彩涂卷哪家好

   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。熱鍍(du)鋅(xin)基板的(de)含鋅(xin)量(liang)一(yi)般為180g/m2（雙(shuang)面），建筑外用熱鍍(du)鋅(xin)基板的(de)鍍(du)鋅(xin)量(liang)高為275g/m2。，在表(biao)面涂(tu)(tu)敷(fu)一(yi)層(ceng)或幾層(ceng)有(you)機涂(tu)(tu)料，隨(sui)后(hou)經過烘(hong)烤(kao)固化而成(cheng)的(de)產品(pin)。也(ye)因涂(tu)(tu)有(you)各種不同顏色(se)的(de)有(you)機涂(tu)(tu)料彩色(se)鋼卷(juan)板由(you)此(ci)得名，簡稱(cheng)彩涂(tu)(tu)卷(juan)。

    使(shi)用(yong)鍍(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)為(wei)基板(ban)(ban)(ban)的彩色(se)涂(tu)層鋼(gang)板(ban)(ban)(ban)，除有(you)(you)鋅(xin)保護外，鋅(xin)層上的有(you)(you)機涂(tu)層起了覆(fu)蓋(gai)隔離作用(yong)，可(ke)防止鋼(gang)板(ban)(ban)(ban)生(sheng)銹，使(shi)用(yong)壽(shou)(shou)命比(bi)鍍(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)更長，據介(jie)紹涂(tu)層鋼(gang)板(ban)(ban)(ban)的使(shi)用(yong)壽(shou)(shou)命比(bi)鍍(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)長50%。 但(dan)是，在不(bu)(bu)同(tong)的地區和不(bu)(bu)同(tong)的使(shi)用(yong)部位，采用(yong)相同(tong)鍍(du)鋅(xin)量、同(tong)種涂(tu)料、相同(tong)涂(tu)層厚度的彩色(se)涂(tu)層板(ban)(ban)(ban)，其使(shi)用(yong)壽(shou)(shou)命會有(you)(you)很大(da)的不(bu)(bu)同(tong)。
