摘要
以3.4mm厚水曲柳弯翘木皮为研究对象,研究采用不同温度的湿空气和不同时间处理对弯翘木皮扭曲度恢复程度的影响。结果表明:在干湿球温差1℃情况下,当处理温度从70℃上升到100℃,温度越高,木皮扭曲度恢复效果越好,从1h延长到3h,处理时间越长,木皮扭曲度恢复效果也越好。结合实际生产需求,生产上较佳的工艺参数为:温度90℃、干湿球温差1℃、处理时间2h。
Taking 3.4mm warped Fraxinus Mandshurica wood veneer as the research object,the authors of this paper studied the effect of wet air treatment under different conditions（different air temperature,and different treatment time）.The research result showed that：under the situation of 1℃of dry-wet bulb temperature difference,along with the treating temperature increasing from 70℃to 100℃and the treating time lasting from 1h to 3hs,the recover effect was strengthened.In consideration of the actual production situations,the authors suggest that the optimum technological parameters should be：90℃of temperature,1℃of dry-wet bulb temperature difference,and 2hs of processing time.
