摘要
利用百度试验法研究灰木莲木材的干燥特性,结果表明:灰木莲属易干木材,干燥速度2级;截面变形程度轻,为1～2级;初期开裂2～3级,扭曲等级2～3级,无内裂,弦径向干缩差异小。根据试验结果,提出25～30mm厚灰木莲木材的干燥基准。
Manglietia glauca drying characteristics were investigated using 100 ℃ constant temperature. The results showed that Manglietia glauca was relatively easy to dry with a Grade 2 drying speed. It was noticed that the main drying defects included initial checks and distortions （from grades 2 and 3）, and cross-section deformation （between grades 1 and 2）. No internal cracks were found in this study and there was little shrinkage difference between tangential and radial directions. Based on these results, a drying schedule for 20～30 mm thick Manglietia glauca was proposed.
