摘要

利用不同能量密度的高能微波对50 mm厚杉木和白梧桐锯材进行预处理，分析其对锯材干燥速率和干燥质量的影响。微波预处理后，两种锯材的干燥均匀度提高，厚度上的含水率偏差和残余应力值降低，但干燥速率基本不变。综合考虑锯材的干燥质量、微波预处理过程功率效率和微波预处理锯材表面缺陷情况，50 mm厚杉木和白梧桐锯材优选微波能量密度分别为168.5、330.2 MJ/m,3,。

Abstract

High-energy microwave with different energy density was used to treat Chinese fir,(,Cuninghamia lanceolate,),and,Obeche,(,Triplochiton scleroxylon,) lumber with 50 mm-thickness. The effects of these treatments on the wood drying rate and drying quality were analyzed. After microwave pretreatment, the drying evenness of two species were improved; the deviation of moisture content in thickness and the residual drying stress value were decreased; while the drying rate remained basically unchanged. Considering the wood drying quality, power efficiency of microwave pretreatment process, and surface defects of pretreated wood, the optimum energy density value was 168.5 MJ/m,3, for Chinese fir and 330.2 MJ/m,3, for Obeche wood respectively.
