基于响应面法的氨复配碱液柚木软化工艺研究

Study on Softening of Teak Plantation with Ammonia Compounding Alkali Liquor Based on Response Surface Method

  • 摘要: 采用响应面法探讨氨复配碱液对柚木蒸汽软化处理工艺,分析药剂含量、水热温度和水热时间对软化性能的影响。结果表明:氨复配碱液能提高柚木软化性能,最优的工艺参数为增重率为37%,处理温度为115 ℃,处理时间为5.8 h,最佳软化条件得到的柚木弯曲性能为0.082,说明本研究的氨复配碱液可用于柚木软化弯曲处理。

     

    Abstract: The response surface method was used to study the steam softening of teak plantation with ammonia compounding alkali liquor, and the effects of wood weight gain rate, hydrothermal temperature and hydrothermal time on the bending performance of wood were analyzed. The results showed that bending property of the teak plantation can be significantly increased by the ammonia compounding alkali liquor. The optimal conditions contained: 37 % weight gain rate, 115 ℃ hydrothermal temperature and 5.8 h hydrothermal time. The measured bending performance has an h/r value of 0.082. It is concluded that ammonia compounding alkali liquor can be applied to the bending of teak plantation.
