摘要: 对常见软垫家具填充物软质聚氨酯泡沫(FPUF)的燃烧特性及其燃烧烟气中窒息性气体组分生成量的变化特性展开实验研究,并采用有效剂量分数FED 模型对烟气毒性进行评价。结果表明:无论是在强制点火模式抑或是非强制点火模式中,不同盐湿度雾滴沉降作用下FPUF 热释放速率(HRR)曲线的发展规律基本相似。FPUF 的着火时间在无强制点火模式中随着空气中雾滴盐度的增加而延长,而在强制点火模式中则基本相近;不同盐湿度空气中FPUF 燃烧生成的各烟气组分生成量的变化规律具有相似性,当量比Φ 值在0.9~1.6 时,高盐湿度空气对各烟气组分生成量影响较大。并且高盐湿度空气中NaCl 的存在将促进窒息性气体组分的生成;高盐湿度空气中盐度的增加对于FPUF 燃烧产生的烟气毒性具有一定的增强作用。

Abstract: Made a experimental study of combustion characteristics of flexible polyurethane foam (FPUF) as a common upholstered furniture filler and variation characteristics of asphyxiating gas components in combustion flue gas. Also the effective dose fraction FED model was used to evaluate the smoke toxicity. The results show that the development law of FPUF heat release rate (HRR) curves under the action of droplet deposition with different salt humidity is basically similar in both forced ignition mode and non- forced ignition mode.The ignition time of FPUF lengthens with the increase of fog droplet salinity in the non-forced ignition mode, but it is similar in the forced ignition mode. The variation rules of each flue gas component produced by FPUF combustion in air with different salt humidity are similar. When the equivalence ratio is 0.9 ~ 1.6, the high salt humidity air has a great influence on the formation of each flue gas component. Moreover, the presence of NaCl in the air with high salt humidity will promote the formation of asphyxiating gas components; the increase of salinity in the air with high salt humidity can enhance the toxicity of flue gas produced by FPUF combustion.
