摘要
对刺楸木材的理化性质进行了研究,分析了刺楸的材性。结果表明:(1)刺楸木材的绝干密度为0.57g/cm3,差异干缩为0.68,说明刺楸的干燥性能较好;(2)根据木材力学性质划分方法,除抗弯弹性模量属低级外,抗弯强度、顺纹抗压强度、综合强度、冲击韧性,均为中等;(3)刺楸的综纤维素含量为82.20%,克见纤维素为43.86%,木素含量为17.6%,符合造纸工业的要求;(4)根据刺楸的理化性质,刺楸可作为优质家具材料、装饰材料、造纸原料。
Wood physicochemical properties of Kalopanax septemlobus were studied and analysed. The resuits showed that. （1） Oven-dry density of Kalopanax septemlobus was 0.57g/cm^3 , differences shrinkage was 0.68, these illustrated that Kalopanax septernlobus has a good dry performance. （2）According to partitioning method of wood mechanical properties, flexural strength, compressive strength parallel to grain, synthetical strength, impact toughness were all at medium level-except for bending modulus of elasticity, which was at the low level. （3）The holocellulose content was 82.20%, lignin content was 17.6 %, these complied with requirements of papermaking industry. （4） On the basis of physicochemical properties of Kalopanax septernlobus, it can be seen that it can be popularized as high-quality furniture material, decoration material, paper raw material.
