提高落叶松材渗透性的工艺研究

Effect of Heat on Osmosis of Larch Timber

落叶松材改性处理的关键研究是它的渗透性 [2 ]。在常温条件下对落叶松板材进行加压处理 ,因温度不能调整 ,试验的动态环境系数变少 ,很难取得预期的处理效果。加热加压法与常温加压法相比 ,把温度作为一个可变参量 ,使用正交分析法进一步研究落叶松材的渗透性。

Larch is one of the most important tree which grows fleetly.The use of larch is limitted to lower grade for a long time.The primary research of modifying larch is to explore osmosis of timber.The result of which Larch timeber is treated with under normal temperature and pressure is hard to obtain prospectively,because temperature is not altered and dynamic parameter is lessened.The means of heat and pressure is used to study larch timber osmosis when temperature is regarded as a transformable parameter under all cross method.
