圆盘豆热处理材光稳定性的研究

Study on light stability of heat-treated Cylicodiscus wood

采用热处理和氙灯照射对圆盘豆木材颜色的变化进行研究,以CIE(1976)L*a*b*表色系统表色,分析木材热处理前后、氙灯照射前后颜色变化。结果表明,热处理后木材颜色加深。随着氙灯照射时间延长,未处理材表面颜色逐渐加深,色差△E*逐渐增大。热处理材表面颜色变化不大,色差△E*值变化较小,这表明与未处理材相比,热处理材光稳定性能更好。

The surface color of Cylicodiscus wood is researched by thermal modification and xenon irradiation, the color changes of Cylicodiscus wood between treated and control test specimens are analyzed by CIE（1976）L ＊ a ＊ b parameters color system. The results show that the surface color of Cylicodiscus wood becomes dark after thermal modification. The surface color of control test specimens becomes darker and darker, △E ＊ increases, and the surface color of thermal modified wood changes less, △E ＊ changes little with the increasing of the duration of xenon irradiation.
