摘要

对兴安岭落叶松髓心方材采用纵向切口处理后,进行高频/真空干燥试验。结果表明,落叶松髓心方材切口处理,能明显减少表面开裂,总表裂长度降低了39%,5,0%;对干燥速度、含水率分布以及干燥收缩均无显著影响。

Abstract

After kerfing treatment along the longitudinal direction,boxed-heart larch lumbers was dried through a series of radio frequency vacuum drying schedules.We found that kerfing could considerably decrease surface checks and reduce the average length of surface check by 39%～50%.However,the kerfing treatment didn’t have any noticeable effects on the drying rate,moisture content distribution dryings or shrinkage.
