摘要
通过酸腐蚀法和涂覆涂层法对堇青石蜂窝陶瓷载体进行表面改性,并采用孔径测定仪(BET)﹑扫描电镜(SEM)﹑X射线衍射仪(XRD)和能谱分析仪(EDS)分别测试了酸腐蚀法和涂覆涂层法对堇青石蜂窝陶瓷载体表面的改性效果。结果显示,经酸预处理后的堇青石蜂窝陶瓷再涂覆改性氧化铝溶胶并在800℃煅烧之后,可以增加堇青石蜂窝陶瓷的介孔数量,从而提高堇青石蜂窝陶瓷的表面特性。
The modification of cordierite honeycomb ceramics surface by acid corrosion and coating method was mainly studied in this paper. The cordierite honeycomb ceramics carrier surface modification effect was detected by BET, SEM, XRD and EDS, respectively. The results showed that the cordierite honeycomb ceramics coating modified alumina sol after 800℃ calcination was beneficial to increase the quantity of cordierite honeycomb ceramics mesoporous, so as to improve the surface performance of cordierite honeycomb ceramics.
