摘要:
为确保聚碳硅烷粉尘作业安全,避免发生火灾爆炸事故,本文按照相应国家测试标准,采用标准测试仪器,对聚碳硅烷粉尘的最小点火能、最低着火温度、爆炸下限浓度3个火灾爆炸特性参数进行了测试。结果表明:聚碳硅烷粉尘最小点火能1.5 mJ<Emin<2 mJ,最低着火温度MIT=320 ℃,爆炸下限浓度12 g/m3<Cmin<13 g/m3。结合常见涉爆粉尘火灾爆炸特性参数范围比对分析,结果表明:聚碳硅烷粉尘最低着火温度和最小点火能均较低、爆炸下限浓度也小,说明该粉尘极易被引爆,安全风险较高。

Abstract:
To ensure polycarbosilane work safely,according to relevant national testing standards and instruments,three fire and explosion characteristic parameters of polycarbosilane dust were tested,including minimum ignition energy,minimum ignition temperature and minimum explosion concentration using the standard instrument.The results show that minimum ignition temperature is 320 ℃,the minimum ignition energy is 1.5 mJmin<2 mJ,minimum explosion concentration is 12 g/m3<Cmin<13 g/m3.Combined with the fire and explosion characteristics of common explosive dust,the minimum ignition energy is low and the minimum explosion concentration is small, indicating that the polycarbosilane dust is easy to be detonated.
