摘要
利用锥形量热仪,在50kW.m-2的热辐射功率下,对1~6年生的毛竹Phyllostachyspubescens人工林竹材的燃烧性能指标进行了测定。结果表明:随着竹龄的增加,毛竹材的点燃时间、释烟总量和比消光面积均有所增大,质量损失率和第一释热峰有所下降,第二释热峰与竹龄无显著相关,但出现的时间延迟;4年生以上的毛竹材各项燃烧性能指标趋于稳定。
Combustion properties of wood of Phyllostachys pubescens aged between 1 year and 6 years were tested with cone calorimeter under the heat radiation of 50 kWm^(-2). The results showed that with the increase in age, ignition time, total smoke release and extinction area of bamboo wood increased while the weightlessness rate and the first heat release peak decreased. There was no significant correlation between the second heat release peak and the age of wood, but the appearance of the second peak was delayed. The combustion properties of Phyllostachys pubescens wood tended to stabilize after the age of 4 years.[Ch,3 fig.2 tab.8 ref.]
