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)。
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.
