Abstract

ABSTRACT Pinus wallichiana and Dalbergia sissoo wood is widely used in the construction and furniture industry in Pakistan. However, directional variability of physical properties, which can be important for wood-based industry, remains poorly documented. In both wood types, water and moisture uptake, water contact angle, and compressional strength varied significantly along the three directions. Water and moisture uptake was found significantly higher in tangential direction while water contact angle, and compressional strength was found the highest along the longitudinal direction in both wood types. Furthermore, thermal conductivity and diffusivity were found the highest along longitudinal direction however, specific heat capacity was found the highest in radial direction. Based on the results it can be concluded that although, dimensional variability was more pronounced in Dalbergia sissoo wood however, studies on site-specific variations in physical properties need further investigations for better recommendations.

南亚原产油松和黄檀木材特性的方向性变异
摘要在巴基斯坦,白松木和黄檀木材被广泛用于建筑和家具行业。然而,对于以木材为基础的工业来说很重要的物理性质的方向变化,仍然缺乏文献记录。在两种木材类型中,吸水率、吸湿率、水接触角和抗压强度沿三个方向变化显著。两种木材的吸水性和吸湿性在切向上显著高于水接触角,抗压强度在纵向上显著高于水接触角。纵向导热系数和扩散系数最高,径向比热容最高。基于这些结果,我们可以得出结论,尽管黄檀木材的尺寸变异性更为明显,但是,对物理性质的具体地点变化的研究需要进一步研究以获得更好的建议。
