摘要：利用锥形量热仪对磷酸铵盐处理的人工林杉木、杨木和马尾松木材的燃烧性能进行研究。结果表明 :磷酸铵盐阻燃处理木材的引燃时间与阻燃剂量有关 ,对 3种木材而言 ,阻燃剂量超过 10 0kg·m- 3,木材才不会被点燃 ;磷酸铵盐对降低木材的释热性能效果明显 ,释热速度降低 ,释热总量减少 ,气相燃烧放热降低 ,而且随着阻燃剂量的增加 ,降低程度更加明显 ;经磷酸铵盐阻燃处理 ,木材失重降低 ,这对保证结构外形的稳定性具有重要作用 ;磷酸铵盐阻燃剂的抑烟作用不理想 ,虽然降低了最强发烟过程的强度 ,但是也提高了最弱发烟过程的强度 ,而且随着阻燃剂量的增加 ,发烟量呈增加的趋势 ;在阻燃研究中 ,阻燃剂在木材内分布状态是一个不可忽视的影响因素 ,特别是木材这种非均质性材料 。
The burning behaviour of the plantation wood (two softwoods and one hardwood) treated with ammonium phosphate (NH 4H 2PO 4) was tested by cone calorimeter in the study. The sample with size of 100 mm by 100 mm (LT or LR section) by 10 mm (thickness) was prepared for fire retardant treatment and cone calorimeter test. The heated area was on LT or LR section, heat flux was 50 kW·m -2. The results showed that the ignition time of the treated wood depended on the amount of the fire retardant and the treated wood could not be ignited when the amount of fire retardant was higher than 100 kg·m -3. The fire retardant was efficient in reduction in the heat release and mass loss and the efficiency in reduction in the heat release was increased with the amount of the fire retardant increased. But the fire retardant was unsatisfactory in retarding smoking. The smoke of the treated wood appears on the whole process of heating, and the strongest and stronger process of smoke production was reduced. However, the weakest process of smoke production became stronger and it was increased with the amount of the fire retardant increase. The distribution of the fire retardant in wood structure was important and it could affect the burning behaviour as a material.
