摘要：探究高场强微波处理过程中,樟子松试材含水率、微波功率、处理时间对试材吸收微波能量和宏观裂纹的影响。结果表明,试材处理前的含水率、微波功率对试材吸收的微波能量有显著影响;当含水率为40%-60%、微波功率为140kW、处理时间为120s时,樟子松试材横截面的裂纹面积比和裂纹数量最大。建议根据功能化材料的应用领域,选择不同的微波处理工艺。
Microwave treatment can cause macroscopic cracks in wood. The effects of moisture content,microwave powers, and treatment times on macroscopic cracks in the cross section of Mongolian scotch pine(Pinus sylvestris var. mongolica Litv.) after microwave treatment were investigated. Results showed that the moisture content and microwave powers had a significant influence on the microwave energy absorption by the Mongolian scotch pine samples. The number of cracks in the cross section of Mongolian scotch pine samples and crack area ratio reached the largest at 40%~60% of the moisture content, 140 k W of the microwave power and 120 seconds of the treatment time. It was suggested that different microwave treatment processes should be chosen accordingly based on the application of materials.
