摘要
基于红外热像和热电偶测温技术,通过建立亮珠模拟发射装置及引燃实验平台,研究不同状态下亮珠的燃烧温度及对典型固体材料的引燃特性。结果表明,直径10 mm亮珠燃烧持续时间2~3 s,燃烧过程中最高温度达1461益。亮珠被发射并飞行32 m后仍在燃烧,且温度为995益。在特定的引燃方式下,亮珠可将聚氨酯泡沫、塑料草坪引燃。通过理论计算与实验测试结果的结合,得到固体材料特征直径计算公式及亮珠引燃判据。该研究结果可为开展礼花燃放过程中的火灾风险评估提供依据。
The burning temperature of pills for display shell is measured by thermocouple infrared thermograph and temperature measure system. The ignition characteristic of pills for display shell on typical solid materials is investigated with simulating emission apparatus and ignition test device. The results show that the highest temperature of 10 mm（ in diameter） burning pills is up to 1 461 ℃,and the burning time is about 2 ~3 s. The pill＆#39;s temperature is about 995 ℃ after being emitted and flying 32 m. All of the solid samples can be ignited by burning pills in special ignition condition. The＆amp;nbsp;pill＆#39;s ignition criterion and the character diameters for solid materials are gained by experimental research and theoretical calculation. The research results are helpful to evaluate the fire risk when the display shell is displayed.
