压缩率对杨木重组木表面硬度的影响
Effect of compression ratios on the surface hardness of poplar wood scrimber
[目的]以人工速生林杨木为研究材料,采用定向重组技术开发高硬度重组木,揭示压缩率对杨木重组木表面硬度的影响规律,以期为杨木的表面改性和重组木制备工艺的优化提供可靠的方法和科学依据。[方法]采用定向重组技术制备压缩率为 1.00、1.22 和 1.44 的三种杨木重组木,并以杨木、红榉和俄罗斯柞木作为对照样,采用万能力学试验机测定三种木材和三种不同压缩率杨木重组木样品表面的金氏硬度值;采用超景深三维显微镜、场发射扫描电镜观察样品表面的宏观和微观形貌…查看全部>>
[Objective]In order to provide reliable methods and scientific basis for the modification of poplar wood surface and the optimization manufacturing process of wood scrimber,the directional recombination technology was applied to manufacture the wood scrimber of poplar with high-hardness,and then the effect of compression ratios(CR)on the surface hardness of wood scrimber was studied.[Method]The wood scrimber with compression ratios of 1.00,1.22 and 1.44 were…查看全部>>
