摘要：为了定量评价东北地区几种主要工业用木材液体渗透性能,该研究采用常压和减压渗透实验方法,测定了东北地区7 种主要工业用木材液体渗透参数的经时变化规律. 研究结果表明: ①染料种类对木材渗透性能的影响很大. 主要受染料分子大小、染料溶液与木材的亲和性等因素制约. ②边材比心材易渗透. ③弦向渗透比纵向渗透难,比值范围为1/ 3～1/ 20. ④减压渗透比常压毛细管压力渗透效果好,尤其对于弦向渗透效果明显. ⑤真空干燥处理的试件比高温干燥试件的渗透性好.

To quantitatively evaluate the liquid permeability of several kinds of important indust rial woodsproduced in Northeastern China , the authors have made many timedependent measurement s on osmotic coefficient s of stains when they were absorbed by seven kinds of woods used widely in the forestindust ry. The experiment s were performed under normal pressure as well as vacuum condition. The
study indicates that : firstly , the stain type has a great influence on wood permeability. The main factors are size of stain molecule , affinity between stain solution and wood , etc. Secondly , the sapwood is
more permeable than heartwood. Thirdly , tangential penet ration is more difficult than longitudinal ,the ratio ranges f rom 1/ 3 to 1/ 20. Forthly , vacuum percolation is more effective than normalpressure
capillary penet ration , especially in tangentially penet rating experiment s. Fifthly , vacuum seasoning samples are more permeable than high temperature drying ones.
