摘要
本文以杉木(Cunninghamia lanceolata(Lamb.)Hook)为实验材料,分别对木材进行高温热处理和超声波预处理,然后再分别对预处理材进行负离子浸渍处理,并对不同预处理条件下得到的浸渍处理材的尺寸稳定性、负离子释放过程和微观结构进行探究,并对负离子释放过程进行模拟。结果表明,两种预处理方式均能提高浸渍材的尺寸稳定性,并且浸渍材的负离子释放效果显著。其中,高温热处理对尺寸稳定性改善效果最佳,且其负离子释放量最为理想;另外,通过电镜图片看出,负离子能够进入木材内部。本研究对提升杉木等速生材的附加值具有重要价值。
Chinese fir （Cunninghamia lanceolata （Lamb.） Hook）was taken as specimens in this paper. Specimens were pretreated by high temperature ultrasound, and then negative ions were impregnated into specimens. The dimensional stability and the negative ion release process and the microstructure of specimens were also analyzed. Results indicate that both ultrasound and high temperature pretreatment could increase wood dimensional stability, and the pretreated specimens could release negative ion, and the high temperature pretreatment has a good effect. Additionally, negative ion could impregnated into wood by microstructure analysis. This study could improve the added value of Chinese fir.
