【摘要】 本文回顾和分析了桉树木材与干燥有关的材性和干燥特性 ,指出桉木的密度、含水率和干缩率变异性大、渗透性差 ,在干燥过程中易产生皱缩、开裂等干燥缺陷 ,若采用预冻处理和前后期调湿处理可减少木材的皱缩 ;同时建议研究各种桉木不同规格板材的干燥基准和两段式干燥工艺更多还原

【Abstract】 This paper reviewed and analysed the drying properties and characteristics of Eucalyptus. It indicated that variations of density, moisture content and shrinkage of Eucalyptus were distinct. Collapse and checks were main defects in drying process. The pre freezing treatment and conditioning before and after drying could reduce wood collapse. Some suggestions for further research of drying schedule and two stage drying technology for various kinds of Eucalyptus lumbers in different sizes were put forward.更多还原
