采用锥形量热研究了5A分子筛与聚磷酸铵(APP)复合在木材燃烧过程中的阻燃性能和烟气转化作用。结果表明:5A分子筛与APP复合使用能有效降低杨木的热释放速率(HRR)、总热释放量(THR)、烟生成速率(SPR)和总烟释放量(TSP),可促进炭的生成,表现出优异的阻燃与抑烟特性。同时,5A分子筛对阻燃过程中释放的烟气具有转化作用,能够有效的降低CO的浓度,具有减毒作用。

　　The flame retardancy and smoke-suppressant effect of flame retardants with the molecular sieve 5A and APP in the wood burning process, in this paper, were studied.The results of CONE showed that: the heat release rote (HRR), the total heat release (THR), the smoke production rate (SPR) and the total smoke production (TSP) decreased remarkably while the charring drastically increased, which indicated that the compound of 5A molecular sieve and APP have excellent inflame-retarding and smoke inhibition effects for wood.Meanwhile, 5A molecular ...
