摘要

对落叶松木材进行热处理,探讨热处理温度和时间对试材颜色指数和力学性能的影响。结果表明:随着处理温度的升高和处理时间的延长,木材的颜色变深,密度和质量降低,各项力学性能亦有下降。

Abstract

Larch lumber was treated at 160 to 220 ℃ for 1 to 4 hours and then evaluated for aberration（ΔE*）,（ΔH*）,（ΔC*）and mechanical properties.The test results showed that the high temperature and duration had remarkable effects on the specimen’s ΔE*,ΔH*,and ΔC*.The treated samples density,weight loss,and mechanical properties changed considerably as the temperature increased and the heating time was extended.
