摘要:
选取木荷、红楠、北美枫香、红果冬青等12种彩色树种,测定叶片的含水率、抽提物含量、抽提后余物发热量、着火点以及枝条的含水率、残炭生成率、发热量、残炭发热量、着火点等指标;以鲜叶中乙醚抽提物燃烧释放出来的热量与水分蒸发所消耗的热量之差作为叶易燃性综合指标,并以鲜枝有焰燃烧释放出来的热量作为枝易燃性综合指标,得出12个彩色树种的易燃性顺序为红果冬青>茶树>油樟>北美枫香>红楠>桂花>油茶>红叶石楠>杨梅>红花深山含笑>木荷>檫树。对可燃性指标较低的檫树、木荷、红叶石楠、红花深山含笑和杨梅等5树种的枯枝叶分别进行火烧强度测定,其中檫树、木荷、红叶石楠3树种的火烧强度最低,抗火烧效果好。
Abstract:
The flammability of fresh leaves of 12 colore woody species (Schima superba,Machilus thunbergii,Liquidambar styraciflua,Ilex purpurea,Cinnamomum longipaniculatum,Myrica rubra,Osmanthus fragrans,Camellia oleifera,C. sinensis,Photinia × fraseri,Michelia maudiae and Sassafras tsumu ) was evaluated by means of comparing the differences between the heat released from the burning of fresh leaf extracts and consumed by moisture evaporation from the same extracts. The flammability of their living branches was also evaluated by comparing their heat released in the process of flaming combustion. It was showed that their flammability was ranked, from high to low, as I. purpurea,C. sinensis,C. longipaniculatum,L. styraciflua ,M. thunbergii,O. fragrans,C. oleifera,P. × fraseri,M. rubra,M. maudiae, S. superba,and S. tsumu. With the latter 5 species to further compare the fire intensity in dry sample burning, we got their fire suppression order, from strong to weak, as S. tsumu, S. superba,P. × fraseri,M. rubra,and M. maudiae, that was, for fire suppression, S. tsumu was regarded as preferable to S. superba.
