摘要
对杉木间伐材进行高温压缩密化处理,并分析和评价压缩密化后木材的回复变定过程.结果表明:处理材的厚度吸湿回复率为2.68%,具有良好的尺寸稳定性,说明压缩变定效果好.通过试验研究得出蒸煮工序加入软化添加剂CH,能使处理材的回复率大大降低,为低密劣质杉木间伐材压缩密化的性能改良提供依据.
An effort was made to compress Chinese fir thinning wood by treating it with high temperature, and the recovery of wood compression set process was also analyzed. The result showed that the treated wood had good dimension stability, and the moisture absorption recovery ratio of thickness was 2. 68%, which indicated that the set of compression was almost fixed. Thus, the experiment results can provide basis for modifying the thinning wood. Furthermore, the recovery ratio of treated wood can be decreased considerably by adding the intenerating agent CH in its cooking process.
