摘要
以失重率作为木材高温处理的强度损失因子,研究热处理对西南桦材色的影响,并对失重率与材色变化进行关联分析。结果表明:西南桦木材的明度、色差随处理温度的上升和处理时间的延长而下降、增加,红绿度和黄蓝度变化规律不明显;失重率随处理温度的上升和处理时间的延长而增加,以其为处理强度损失因子对明度变化和处理前后试材色差具有良好的指示性。
Taking mass loss as the intensity damage indictor after the heat treatment was applied to the wood,the impact of heat treatment on the color of Betula alnodies wood was studied,and the correlation analysis between the mass loss and color change was conducted.It was showed that the lightness of the wood was decreased,whereas the color difference was increased along with the increment of treating temperature and treating time duration.There was no distinct rule for the change of the color parameters L*,a*,and b* determined by the CIELAB method.The mass loss was increased with prolonging of the heat treatment,which might be applied as a right index to indicate the lightness change and color difference before and after the heat treatment.
