摘要
木材是一种多孔性、吸湿性和各向异性的天然高分子材料,水分影响着木材多方面的性质。文中从木材组分的角度综述了木材对水分的吸湿机理,介绍了木材对水分吸附的基本理论,解释了木材吸湿滞后现象的基本原因;在上述基础上评述了降低木材吸湿性的基本方法及其实现原因,还分析了机理应用方面存在的不足以及测试方法的不统一,并对未来研究趋势进行了展望。
Wood is a kind of natural polymer material that has porosity,hygroscopicity and anisotropy,and moisture affects many properties of wood. This article reviewed the mechanism of wood moisture absorption from the perspective of wood components,introduced the basic theory of adsorption of wood for moisture,explained the basic reasons of wood sorption hysteresis. Based on the above analysis,the basic method to reduce hygroscopicity of wood and its realization causes were expounded. The article also analyzed the deficiency of the mechanism in application and the variation of testing method,and prospected the future research trend.
