为优化藤材改性处理的方案、提高其加工利用水平,以钩叶藤、高地钩叶藤为研究对象,对其改性处理前后主要物理性质的变化进行分析。结果表明,与素材相比,经过120℃热处理后,钩叶藤密度略有增加;钩叶藤和高地钩叶藤抗胀(缩)率分别为11.94%和1.98%,阻湿率分别为4.80%和5.50%,此外高地钩叶藤的抗吸水率为1.80%。按最佳工艺改性处理后,气干密度、绝干密度和基本密度钩叶藤分别增加了9.71%、9.03%和11.70%,高地钩叶藤分别增加了23.57%、22.11%和18.18%;钩叶藤的抗胀(缩)率为5.40%,钩叶藤和高地钩叶藤抗吸水率分别为13.25%和34.16%。经过上述改性工艺处理后,对钩叶藤和高地钩叶藤密度、尺寸稳定性、阻湿性和抗吸水性有着不同的影响。
In order to optimize the plan of modification treatment of rattan and improve its processing and utilization level, the changes of the main physical properties before and after the modification were analyzed by taking the Hook-leaf rattan and the Hookley highland as the research objects. The results showed that the density of Hookweed increased slightly after heat treatment at 120 ℃ compared with the control; the anti-dilatation and deflation rates of Hookweed and Hookweed were respectively about 11.94% and 1.98%, and the moisture resisting rates were 4.80% And 5.50% respectively. In addition, the anti-water absorption rate of Hookwort was 1.80%. The average dry density, absolute dry density and basic density of Hookweed increased by 9.71%, 9.03% and 11.70%, respectively, and Hook increased by 23.57%, 22.11% and 18.18% respectively. The anti-swelling (contracting) rate of Hook’s leaf vine was 5.40%, the anti-water absorption rate of Hook’s leaf vine and Hook’s hook was 13.25% and 34.16% respectively. After the above-mentioned modification process, the density and dimensional stability, moisture resistance and water absorption of Hookweed and Hookweed have different effects.
