硅灰石纤维添加量对水成膜灭火剂抗烧性能影响的实验研究
|
摘要
通过在水成膜泡沫灭火剂中添加硅灰石纤维粉形成三相泡沫灭火剂,研究了硅灰石纤维粉添加量对三相泡沫灭火剂起泡性、析液时间以及抗烧性的影响,具体介绍了实验方法。结果表明含硅灰石纤维粉的三相泡沫灭火剂在稳定性和抗烧性等方面均有显著提高,当硅灰石粉浓度达到30.00 g/100 mL时,50%析液时间为22.1 min,比两相水成膜灭火剂延长了约13min,实现了完全抗烧。
Three-phase foam fire extinguishing agent was formed by adding wollastonite fiber powder into aqueous film forming foam extinguishing agent. The effect of wollastonite fiber powder content on foaming property, drainage time and burn resistance of the three-phase agent was studied and the experimental method was introduced in detail. The results showed that the stability and anti-burning property of the agent were improved significantly. With the wollastonite powder concentration of 30.00 g/100 ml the 50% drainage time reached 22.1 mins, about 13 mins longer than that of the two-phase aqueous film forming extinguishing agent and the complete anti-burning performance was achieved.
