国产麻栎和栓皮栎木材的主要物理性能

Physical Properties of Native Quercus Acutissima and Quercus Variabilis Timber in China

按照国家标准要求,对国产麻栎和栓皮栎木材的主要物理性能进行测试。结果表明:麻栎与栓皮栎木材的密度等级为大,气干密度径向变异均表现为心材密度比边材密度大;麻栎和栓皮栎木材的径向尺寸稳定性优于弦向,边材优于心材。栓皮栎尺寸稳定性稍优于麻栎。

The physical properties of native sawtooth oak(Quercus acutissima)and oriental oak(Q.variabilis)timber in China were tested according to relevant Chinese national standards.The results showed that the air dried wood density of the tested timber were high and increased gradually from bark to pith.The dimensional stability in the radial direction presented better than that in the tangential direction,and the dimensional stability of the sapwood was greater than that of the heartwood.The shrinkage and swelling of Q.variabilis wood samples were less than those of Q.acutissima.Therefore,the dimensional stability of Q.variabilis was little bit better than that of Q.acutissima.
