摘要

对热处理后的樟子松、落叶松和扭叶松木材,进行室内耐腐性和力学性能检测,结果表明:随着处理温度的升高和处理时间的延长,3种木材的耐腐性明显增强;木材的弹性模量和抗弯强度均随着处理温度的升高,呈现先增后减的趋势。

Abstract

Decay resistance and mechanical properties of heat treated Mongolian Scotch Pine,Dahurese Larch,and Beach Shore Pine solid wood samples were studied.Heat treatment temperatures ranged from 180 to 230 ℃ and the treatment duration ranged from 1 to 3 hours.The results indicated that higher temperature and longer time improved sample decay resistance.However,when compared to the untreated wood,the heat treated samples had increased mechanical properties at lower temperatures and then deteriorated under higher temperatures and prolonged duration.
