以部分竹材和木材为参照,研究了厚壁型巨龙竹的密度、干缩性、湿胀性、吸水性4项物理性质。结果表明:厚壁型巨龙竹的基本密度为0.68g/cm3,比毛竹的密度(0.756g/cm3)小,比龙竹、甜龙竹和其他建筑用木材的密度要大;从竹材干缩性上看,厚壁型巨龙竹的气干体积干缩率为12.47%,比毛竹(3.733%)等竹材、木材的相应值要高;从巨龙竹基部到梢部的纵向变异来看,厚壁型巨龙竹秆材密度呈上升趋势,吸水率呈递减趋势,而干缩性及湿胀性在纵向上的变化规律不明显。
Taking bamboo and timber as reference, the physical properties of density, shrinkage, wet expansibility and water absorption of thick-walled giant dragon bamboo were studied. The results showed that the basic density of thick-walled giant dragon bamboo is 0.68g / cm3, which is lower than the density of bamboo (0.756g / cm3). The density of bamboo is larger than that of bamboo, sweet bamboo and other construction timber. Shrinkage point of view, thick-walled giant bamboo air-dry volume shrinkage rate of 12.47%, than the bamboo (3.733%) and other bamboo, timber corresponding value is high; from giant dragon bamboo base to the tip of the vertical variation Look, thick-walled dragon bamboo densities showed an upward trend, water absorption showed a decreasing trend, while the shrinkage and wettability in the vertical changes in the law is not obvious.
