高分子水凝胶灭火剂扑救建筑火灾研究

为测试高分子水凝胶灭火剂扑救建筑火灾的灭火效果，以GB 17835-2008《水系灭火剂》中A类火灭火试验相关规定为参照，搭建木垛实验平台，模拟火灾荷载密度为2 395.008 MJ/m2（相当于一家服装店的火灾荷载）的建筑火灾，且在相同条件下，对比测试高分子水凝胶与水两种灭火剂的灭火效果，并利用车泵压、流量等相关关系计算得出高分子水凝胶灭火剂在建筑火灾扑救中的灭火强度。试验对比分析结果表明，高分子水凝胶灭火剂的灭火时间比水灭火剂的灭火时间短，其灭火效果优于水；同时依据相关计算得出高分子水凝胶灭火剂扑救建筑火灾的灭火强度约为0.059 L/（s.m2）。

Experimental study on macromolecule hydrogel fire extinguishing agent fighting building fire

Abstract: In order to test the fire-extinguishing effect of macromolecule hydrogel fire-extinguishing agent in the fire-fighting of buildings, a kind of fire-fighting test in GB 17835-2008,Water System Fire-extinguishing Agent was used as reference, and a wooden crib test platform was set up, under the same conditions, the fire suppression effects of two kinds of fire extinguishing agents, macromolecule hydrogel and water, were compared and tested in the building fire with the simulated fire load density of 2 395.008 MJ/m2(equivalent to the fire load of a clothing store), the fire-extinguishing intensity of the polymer hydrogel fire-extinguishing agent in building fire-fighting is calculated by using the correlation relations of vehicle pump pressure and flow rate. The results show that the fire extinguishing time of polymer hydrogel is shorter than that of water, and its effect is better than that of water. At the same time, according to the relevant calculation, the fire-fighting intensity of the polymer hydrogel fire-extinguishing agent is about 0.059 L/(s.m2).
