圆盘豆热处理材光稳定性的研究

摘要

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.%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.
