木材脱脂研究现状分析

Research Status on Wood Deresination

有脂木材未进行脱脂处理会造成树脂渗出,从而影响木制品的油漆性能,因此木材脱脂技术在木材工业中起着重要作用。本文通过对比分析有脂材的脱脂方法得知:1)目前研究最多的脱脂方法是高温汽蒸法与碱液法,前者应用较成熟,后者脱脂率较高;2)脱脂研究最多的树种是松科的马尾松与兴安落叶松,而柏木脱脂研究稀少。根据现有的脱脂工艺研究基础与柏木结构特征,本文提出了柏木脱脂研究的若干建议,以期为其提供参考。

The resin-rich wood without deresination process will result in the exudation of resin,which will affect the painting performance of wood products.So it is important to remove resin in the wood industry.Through comparative analysis of the deresination methods,the results show that:(1)At present,the most studied deresination methods are high-temperature steaming method and alkaline liquor method,the former is more mature and the latter has higher degreasing rate;(2)Pinus massoniana and Larix gmelini are the most studied tree species,while cypress degreasing research is rare.According to the available research foundation of deresination technology and structural characteristics of cypress,some suggestions are put forward for providing reference for cypress deresination research.
