采用正交试验方法研究了湿地松脱脂技术。研究表明 ,影响脱脂综合指标的因素主要有 :脱脂液浓度、温度、处理时间、水与木材的体积比。当浓度为 0 5 %,温度为 80℃ ,处理时间为8h ,水与木材体积比为 4时 ,脱脂处理后综合指标最高。经脱脂处理后力学性能降低较小 ,色泽变化不大 ,也不需另外对湿地松进行脱松节油处理 ,即可作家具或装潢材料使用。 Orthogonal test method was used to study the skid removal technology. The research shows that the main factors that affect the comprehensive index of degreasing are: degreasing liquid concentration, temperature, treatment time, water and wood volume ratio. When the concentration is 0 5%, the temperature is 80 ℃, the treatment time is 8h and the volume ratio of water to wood is 4, the comprehensive index after degreasing treatment is the highest. After degreasing the mechanical properties to reduce the smaller, little change in color, and also do not need to separate the pine loose oil-saving treatment, you can make furniture or decorating materials.
