摘要
选取我国实木家具和实木地板生产所用的热带硬木风车木(Conbretum imberbe)为试材,进行温度和湿度分别为72℃、42%及67℃、45%的常规干燥工艺试验,探讨了2种干燥条件下木材的干燥速度、含水率分布、干燥应力及木材的干缩情况。研究结果表明:1)试验1和试验2的干燥速度基本一致。2)试验1的表心层含水率分布与应力指标略优于试验2。3)两种工艺都适合风车木的干燥,试验1的基准更加合适。
In this paper,tropical Conbretum imberbe as solid wood furniture and solid wood flooring pro-duction material was conducted with the conventional drying. The drying condition of temperature and hu-midity were 72 ℃,42% and 67 ℃,45%,respectively. The drying speed,moisture content distribution,drying stress and dry shrinkage of the wood under two drying conditions were discussed. The resultsshowed that：1）The drying speeds of test 1 and test 2 were basically the same. 2）The moisture content ofthe surface layer and the stress index of test 1 was slightly better than that of test 2. 3）Both drying sched-ules are suitable for the drying of Conbretum imberbe and the schedule 1 of the test 1 is more better.
