摘要
在分析了杨树木材与干燥有关的材性和干燥特性的基础上,指出其在干燥过程中易产生皱缩、开裂等干燥缺陷。若采用预处理和前后期调湿或两段干燥式工艺可在一定程度上减少或避免木材的皱缩。还讨论了杨树木材皱缩研究的发展趋势。
This paper analyzed the drying properties and characteristics of Poplar. Collapse and cracks were main defects in drying process. After the treatment, such as pre-freezing, heating, later conditioning and two-stage drying process, the collapse could be diminished. The development tendency about wood collapse was discussed.
