摘要

系统研究了微波功率密度、辐射时间和木材初含水率（MC）对马尾松木材脱脂率的影响规律。结果表明,脱脂率随微波功率密度的增大和辐射时间的延长而增加,随初含水率的增加呈先增后减的趋势。优化脱脂工艺为:微波功率密度4 000 kW/m,3,、微波辐射5 min、试件初含水率约80%,马尾松木材的脱脂率达56.24%,且试件内外层脱脂率无显著差别。

Abstract

Effects of microwave power density, radiation time and initial wood moisture content（MC） on resin removal from Pinus massoniana lumber were studied. The results showed that the resin removal rate increased by increasing the microwave power density and extending the radiation time. As initial wood MC increased, the resin removal rate increased in the beginning and then decreased. The optimal parameters were: microwave power density of 4 000 kW/m,3, microwave radiation time of 5 min and initial wood MC of about 80%. The resin removal rate of Pinus massoniana lumber reached 56.24% with no significant difference between inside and outside layer of the lumber samples.
