摘  要:
利用锥形量热仪器,对毛竹(Phyllostachys heterocycla cv.pubescens)、枇杷(Eriobotrya japonica)、油茶(Camellia oleifera)、栀子(Gardenia jasminoides)、杨梅(Myrica rubra)和茶(C.sinensis)6种浙江省常见经济树种鲜叶片的着火感应时间(TTI)、热释放速率(HRR)、热释放速率峰值(HRRpeak)、热释放总量(THR)、烟释放总量(TSR)、CO释放量(YCO)和CO2释放量(YCO2)7个燃烧性指标进行测定。结果表明:油茶和毛竹的着火感应时间短、热释放速率高、热释放量高,易燃,阻火性能差;而杨梅、茶、枇杷和栀子着火感应时间长,在各项燃烧指标中,峰值较低或最低,热释放速率缓慢,释热量少,是难燃的抗火性强的树种。

摘  要:
To construct the economic fire belt in Zhejiang,six dominant economic tree species in Zhejiang province were selected for experiment,like Phyllostachys heterocycla cv.pubescens,Eriobotrya japonica,Camellia oleifera,Gardenia jasminoides,Myrica rubra and C.sinensis.Their fresh leaves were tested systematically by cone calorimeter to test time to ignition(TTI),heat release rate(HRR),peak of heat release rate(HRRpeak) and total heat released(THR),as well as total smoke release(TSR),CO and CO2 production(YCO,YCO2).Based on the thermal-calorimetric analysis and smoke spread test data,the examined tree species were clustered to 2 groups,one included 4 species(C.sinensis,G.jasminoides,M.rubra and E.japonica),which had characters of relatively longer time to ignition,lower heat release rate and lower total heat release,while the other group included C.oleifera and Ph.heterocycla cv.pubescens,with characters of flammable.
