摘要: 为提升水系灭火剂的灭火效率,设计实验室测试方法并搭建实物模型,研究高分子水凝胶灭火剂的应用性能。首先,分析高分子水凝胶灭火剂的保水性、黏附性等基础性能;然后,在水凝胶灭火剂中添加5大类24种添加剂,在实验室分别测试其性能,并与原灭火剂做对比,筛选出黏附性、耐高温性最佳的添加剂;最后,搭建实物模型,验证改进后的水凝胶灭火剂的性能。结果表明:凹凸棒土对水凝胶灭火剂的黏附性和耐高温性的提升效果最佳;添加凹凸棒土的改进灭火剂能降低罐壁峰值温度,并延迟罐壁达到峰值温度的时间,对相邻罐的冷却效果良好。

Abstract: In order to improve the efficiency of water extinguishing agents, a laboratory test method is designed and a physical model is established to study the application performance of polymer hydrogel extinguishing agents. Firstly, the basic properties of polymer hydrogel extinguishing agents, such as water retention and adhesion, were analyzed. Then, twenty four additives of five categories were added to the hydrogel extinguishing agent before their properties were tested separately in the laboratory and comparison was made with the original extinguishing agent to select the additives which feature the best adhesion and high temperature resistance. Finally, a physical model was built and the performance of the improved hydrogel fire extinguishing agent was verified. The results show that attapulgite has the best effect on improving the adhesion and high temperature resistance of hydrogel fire extinguishing agents; the improved fire extinguishing agent with attapulgite can lower the peak temperature of tank walls, delay the time it takes to reach the peak temperature and proves good in cooling the adjacent tank.

Key words: polymer hydrogel, fire extinguishing agent, tank fire, adhesion, test method
