| 摘 要： | 研究硼琢处理对橡胶木热改性材颜色和力学性能的影响。结果显示，1％浓度硼砂溶液预处理，对热改性材的颜色没有影响，当硼砂浓度增加到4％或8％时，木材材色有偏红的趋势。在185℃的热改性条件下，经硼预处理的热改性材的抗弯强度高于对照，在200℃条件下热改性后则无此规律。分析认为，硼预处理对热改性过程有一定影响，但并不是影响热改性材颜色和力学性能的主要因素。

| Abstract: | The color and strength of heat-treated rubber wood which were impregnated by sodium borate were evaluated. Wood treated with 1% sodium borate solution showed no significant difference compared with control samples; when treated with 4% or 8% sodium borate solution, the color of wood turned red slightly. When the temperature of heat treatment was at 185℃, borate impregnation had a positive effect on wood strength, but when the temperature of heat treatment went as high as 200℃, the positive effect could not be observed. Borate impregnation affected the property of heat-treated wood, but it was not one of the fatal factors. |
