几种木材干燥方法机理及其对木材浸注性的影响*

木材干燥是木材工业应用中必不可少的一环 ,木材的浸注性或渗透性又是关系到木材改性成功与否的重要前提。因此 ,开展不同干燥方法对木材浸注性或渗透性影响的研究 ,将对开展低质人工林木材功能性改良、提高其质量和利用价值的新技术与新方法的研究 ,具有重要理论指导作用。文中就高温干燥、高频 /真空干燥、微波干燥、冷冻干燥和大气干燥等干燥方法的机理及其对木材浸注性或渗透性影响的研究工作进行了全面综述

Mechanism of Several Different Drying Methods and Their Effects on Liquid Impregnation or Permeability of Wood

Wood drying is an indispensable process in wood industry. Liquid impregnation or permeability of wood is an important property related to wood modificatison. Therefore, the studies on the effect of different drying methods on wood impregnation or permeability have fundamental guidance for the reasonable and efficient utilization of low quality plantation wood. This paper introduced the mechanism of several different drying methods(high temperature drying, radio frequency/vacuum drying, microwave drying, freeze drying and air drying) and reviewed the studies on the effect of various drying methods on liquid impregnation or permeability of wood.
