杨、柳软质木材改性工艺研究及其物理性能比较

Study of Softwood Modification Process and Comparison on Mechanical Properties of Poplar and Willow

杨树、柳树是中原地区主要的速生树种,为充分利用速生林软质木材,研究其改性工艺,提高木材品质。作者通过对杨、柳木干燥改性实验,对软质木材进行改性。改性后木材尺寸稳定性增强、硬度大幅增大,杨树、柳树硬度分别提高49.2%、40.1%;木材的抗弯强度分别提高49.0%、51.5%。

The poplar and willow have been main fast growing species in the central plains.In order to make full use of fast-growing softwood,research on modification process and improving wood quality has been very necessary.In this paper,research on the modification experiment of poplar and willow was made.The dimensional stability and hardness of modified wood increased significantly.The hardness of poplar and willow increased by 49.2% and 40.1% respectively;the bending strength of poplar and willow increase by 49.0% and 51.5% respectively.
