Foam fire extinguishing agent

Abstract

The present invention discloses a foam fire extinguishing agent, wherein a ratio of the foaming agent to the water in the foam fire extinguishing agent is 1:99. According to the present invention, the foam fire extinguishing agent has advantages of safety, no toxic-side effect, strong foam adhesion, long lasting effect, good thermal insulation effect, good heat radiation resistance, effective combustible solid re-combustion control, substantially-reduced operation intensity, on-site fire extinguishing efficiency, and fire extinguishing performance enhancing, wherein the fuel and the oxygen are separated through the steam barrier, such that the fire extinguishing efficiency of the foam fire extinguishing agent is about 10 times than the fire extinguishing efficiency of the pure water.

Description

technical field [0001] The invention relates to the technical field of fire fighting, in particular to a Class A foam fire extinguishing agent with a mass ratio of foam liquid to water of 1:99. Background technique [0002] With the acceleration of urbanization in our country, the phenomenon of insufficient water supply capacity of the fire hydrant system is very prominent. In recent years, due to the widespread use of foam fire extinguishing agent (the water utilization rate of fire extinguishing agent is high, only 1 / 5-1 / 10 of the traditional water consumption), the above phenomenon will be significantly alleviated. The foam fire extinguishing agent contains surfactant. When added to water, it can produce foam liquid. The foam liquid is composed of many small droplets. Compared with direct water fire extinguishing, it has a larger surface area and absorbs heat faster. Its fire extinguishing agent is suitable for areas such as: buildings, textile thickets and pastures, lan...

AI Technical Summary

Problems solved by technology

[0003] But the ratio of the foam liquid and water in the foam fire extinguishing agent of the prior art is all 3% or 6%, and because the surfactant activity used in the blowing agent in the foam liquid is not good enough, brings foaming Insufficient capacity, insufficient foam concentration during fire extinguishing, insufficient foam surface area, etc.

At the same time, due to the insufficient composition of the surfactant in the prior art, the adhesion of the foam is not strong, the durability is low, the heat insulation and heat radiation protection effects are not good enough, and the reburning of the solid cannot be effectively controlled, which increases the difficulty of operation. inefficiency
