Abstract

The invention relates to a class A foam fire extinguishing agent based on C4 twinned fluorosurfactant, which mainly consists of the following components in terms of mass percentage: fluorosurfactant 2-5%, foaming agent 5-15%, and the foam is stable Agent 1-3%, water 70-95%, wherein the fluorosurfactant is an anionic twinned fluorosurfactant with a fluorocarbon chain length of 4 carbons. The Class A foam fire extinguishing agent of the invention can effectively control the re-ignition of solid combustibles, greatly reduce the operation intensity, improve the on-site fire extinguishing efficiency, have a wide fire extinguishing range, and have a high utilization rate of fire-fighting water.

Description

technical field [0001] The invention relates to a foam fire extinguishing agent, in particular to a foam fire extinguishing agent for Class A fire. Background technique [0002] Class A fires are solid substance fires. This substance often has the nature of organic substances, and generally produces glowing embers when burned, such as fires such as wood, coal, cotton, wool, hemp, and paper. As cities become larger and more expensive, Class A fires cause more and more losses to the society, making it more difficult to fight fires, posing a huge threat to life and property. The fire extinguishing method of Class A fire generally adopts water cooling method and ordinary foam fire extinguishing agent, but for substances that avoid water, such as cloth, paper, etc., the loss caused by water stains should be minimized, and carbon dioxide, halogenated alkanes, and dry powder fire extinguishing agents are generally used Extinguishing. But these several kinds of fire extinguishing...
