改性处理对黄藤及单叶省藤主要物理力学性质的影响

棕榈藤作为一种重要的生物质材料,其利用对部分替代木材和保护森林资源发挥着重要作用。以黄藤和单叶省藤为研究对象,通过对其改性处理前后主要物理力学的性质变化进行研究,提高我国棕榈藤资源高附加值加工利用水平。研究结果表明,两种藤材通过改性处理后,除部分吸湿率升高之外,其他物理力学性质均有所改善,如抗弯弹性模量、抗弯强度、抗压弹性模量、抗压强度、密度、体积干缩率、吸水体积膨胀率以及材质均匀度等。

Effect of modification on the main physical and mechanical properties of Daemonorops margaritae and Calamus simplicifolius

As a kind of biomaterial,the use of rattan has very important function in replacing wood partly and protecting forest resources.In order to improve the levels of high value-added processing and utilizing for Chinese rattan resources,Daemonorops margaritae and Calamus simplicifolius were chosen as experimental ma-terials and the main physical and mechanical properties were studied before and after the modification.The results show that after being modified,all the physical & mechanics properties such as MOE,MOR,compression modulus & strength,density,shrinkage,swelling of sorption,degree of homogeneity are significantly improved than untreated rattans.
