摘要
研究了铁木豆的干燥特性,根据干燥缺陷等级试验确定出了适合铁木豆的干燥基准,结果表明:铁木豆的主要干燥缺陷为初期开裂、截面变形,此外,铁木豆的初期开裂、截面变形、内部开裂、扭曲变形的等级分别为5、3、1、2级,铁木豆属于难干木材。
Based on 100℃ drying test, the article studies the drying characteristics of swartizia. According to the grades of drying defects, the drying schedules for swartizia are established. The results show that swartizia's main drying defects are the initial check and the cross section deformation, tn addition, the grade of swartizia's initial check, cross section deformation,inner crack and the twist deformation is respectively 5,3,1 and 2. Therefore,the swartizia is a kind of wood which is difficult to be dried.
