摘要
为了解葡萄藤材的基本材性,提高我国非木材类植物资源高附加值加工利用水平,应用X射线衍射法测定了葡萄藤材的微纤丝角和结晶度。结果表明:微纤丝角变化范围在38.4—50.0°之间,平均值约为44.1°,与木材的微纤丝角相比偏大;纤维素结晶度变化范围在32.6%—41.0%之间,平均值约为37.4%,与木材的结晶度相比偏小。实验为葡萄藤材的加工利用提供了理论依据。
In order to find out the properties of grapevine and improve the levels of high value-added processing and utilization of Chinese non-wood resources,the microfibril angles（MFA） and crystallinity index（CrI） were measured through X-ray diffraction method.The results showed that the MFA of the grapevine varied from 38.4°to 50.0°with the average value of 44.1°,which was larger than that of wood;the CrI was in the range of 32.6%-41.0%,and the average CrI was 37.4%,which was lower than that of wood.The research provides theoretical basis for development and utilization of grapevine.
