摘要
利用百度试验法研究了山白兰木材的干燥特性,结果表明:山白兰木材属易干木材,主要干燥缺陷为初期开裂和扭曲变形,两项缺陷等级均达到3级;干燥速度2级,较快;截面变形1～2级,无内裂。参照百度试验缺陷等级以及干燥缺陷对应的干燥条件制定了25～30mm厚山白兰木材干燥基准。
Drying characteristics of Paramichelia baillonii timber were investigated based on the 100℃ test method. The results showed that the timber was easy to be dried, the major drying defects were initial crack and twist deformation with the levels of 3. The drying rate reached at 2, belonging to quick drying grad. Cross-section deformation rate was from grade 1 to 2, no internal cracks. To overcome the defects, it was suggested that the thickness of the timber to be dried should be between 25 to 30 mm.
