摘  要：
以速生杨木为研究对象,采用窑室常压热处理炭化工艺,研究炭化处理后杨木板材的耐热、耐湿尺寸稳定性以及导热性能方面的变化。结果表明,经过该工艺处理后,材料的耐热收缩率和耐湿膨胀率均下降,材料的尺寸稳定性均显著提高。炭化处理后,在湿胀稳定性方面,不同试材长度方向提高了6.67%~81.82%,宽度方向提高了27.47%~80.68%;在干缩稳定性方面,长度方向提高了21.32%~54.22%,宽度方向提高了62.34%~85.67%;材料的导热系数增加27.52%,导热性能显著提高。

摘  要：
In this paper, fast-growing poplar wood was the study object and a study was made on the heat-resistant and wet-resistant dimensional stability and changes in thermal conductivity of the poplar wood panels treated with kiln-type atmospheric pressure heat treatment carbonization techniques. The results showed that the heat-resistant shrinkage rate and wet-resistant expansion rate were both decreased after the treatment, and the dimensional stability of the treated wood improved significantly. For different testing wood, the wet expansion stability of the carbonized wood was increased by 6.67% ~81.82% in the direction of length and by 27.47% ~80.68% in the direction of width. The dry shrinkage stability of the carbonized wood was increased by 21.32%~54.22% in the direction of length and by62.34% ~85.67% in the direction of width. Compared with untreated wood, the thermal conductivity coefficient of the carbonized wood was increased by 27.52%. The thermal conductivity property of the carbonized wood was improved significantly.
