摘要/Abstract

摘要： 为更有效地扑灭密集堆垛火灾,在前期合成试验的基础上,用对比试验的方法,分别将一定浓度的温敏性P(NIPAm/AA-Na)凝胶水溶液和水配比成新型灭火剂,根据《水系灭火剂》标准,将经过密集化处理的、灭火级别为1A的堆垛作为灭火对象,开展密集堆垛火灾灭火试验。结果表明:同等条件下,和水相比,新型灭火剂成功扑灭了密集堆垛火,并且灭明火时间、灭火时间和录像灭火时间都明显缩短;同时在灭火过程中,灭火剂发生溶胶/凝胶相转变,但未检测到新的毒害气体。

Abstract: In order to extinguish the dense stacking fire effectively, based on the previous synthesis experiment, contrast tests on extinguishing dense stacking fire were carried out with temperature sensitive P (NIPAm/AA-Na) gel aqueous solution and water respectively. The stacking used in the tests was densified based on Water Beased Extinguishing Agent standard of fire rating for 1A stacking. The results of the tests show that the dense stacking fire was extinguished successfully with P (NIPAm/AA-Na) gel aqueous solution, that the flame extinguishing time, the extinguishing time and the video fire extinguishing time recorded when the P (NIPAm/AA-Na) gel aqueous solution is used as the extinguishing agent are all significantly shorter than water those recorded when water is used as the extinguishing agent under the same conditions, that a sol/gel phase transition occurs when the temperature sensitive P (NIPAm/AA-Na) gel water solution is used, and that no new toxic gas is detected during the fire extinguishing process with the temperature sensitive P (NIPAm/AA-Na) gel aqueous solution.

Key words: dense stacking, temperature sensitive, extinguishing agent, extinguishing time, fire suppression efficiency
