摘要

为了改进橡胶木热处理工艺,采用过热蒸汽作为传热介质,进行橡胶木热处理,检测处理过程中,橡胶木释放有机酸的量,并探讨有机酸对材性的影响。结果表明,提高热处理温度,延长高温阶段处理时间,试材释放有机酸量增加;随着有机酸释放量的上升,橡胶木的平衡含水率降低,质量损失率增加,颜色变深,抗弯强度下降,耐腐性改善。

Abstract

In order to improve rubber wood heat treatment technology,the authors investigated the amount of organic acid released and its effect on rubber wood performance during high temperature heat treatment.The results indicated that increasing the temperature and the heat treatment duration increased the amount of organic acid released which improved the color appearance and decay resistance of treated wood.However,it possibly had a negative impact on bending strength.
