大白藤和小白藤纤维形态及主要物理力学性质
|
摘要
以大白藤和小白藤为研究对象,统计分析了2种藤材纤维径向变异特性,并研究了其主要物理力学性质,为其加工利用提供参考。结果表明,纤维形态在由藤皮到藤芯方向上,大白藤和小白藤的纤维长度均逐渐下降,分别为1 885.78μm和1 528.94μm。小白藤纤维长宽比>90,壁腔比<1.3,比较适宜作为造纸原料。与小白藤相比,大白藤具有较高的密度和较低的干缩性。两者均有着较好的抗弯性能,且大白藤抗压性能优异。
Rattan canes of Calamus faberii and C.balansaeanus were chosen as experimental materials,the fiber characteristics of them in radial directions were counted and analyzed,and the main physico-mechanical properties of the rattan canes were studied in order to provide references for the cane processing and utilization.The results showed that the fiber length of C.faberii and C.balansaeanus were 1 885.78 and 1 528.94 μm,respectively.Both of them declined gradually from outside to inside in radial direction.The length-width ratio of C.balansaeanus was over 90,and the cell wall-lumen ratio was below 1.3,so C.balansaeanus cane was suitable for papermaking raw material.Compared with C.balansaeanus,C.faberii had a higher density and lower shrinkage.Both had good flexural behavior,and C.faberii had excellent compressive properties.
