Abstract

The invention provides a fine water mist-type water based extinguishing agent. The fine water mist-type water based extinguishing agent comprises a first fire extinguishing composition and a second fire extinguishing composition. According to the fine water mist-type water based extinguishing agent, water based extinguishing agent fire-extinguishing time and anti-reflash time are improved greatly because of water drop anchoring effect and spreading effect caused by electrostatic attraction among polymer additives with opposite charges; and at the same time, the degradability of the fine water mist-type water based extinguishing agent is much better than that of most water based extinguishing agents in the prior art, and less environmental influence is caused.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and relates to a water-based fire extinguishing agent and a use method thereof, more specifically, to a fine water mist type water-based fire extinguisher and a use method thereof. Background technique [0002] According to the theory of fire-fighting and combustion, fire is a combustion reaction of combustibles, which requires three conditions: combustibles, combustibles and ignition sources. Therefore, the basic principle of fire prevention and control is to destroy one or several conditions of combustion. When combustibles are burned, corresponding fire extinguishing methods must be adopted to interrupt the burning and reduce the fire hazard to a certain extent. Fire extinguishing can be carried out through four basic principles of cooling, suffocation, isolation, and chemical suppression. The usual fire extinguishing agent is that two or more basic principles work together. [0003...
