Abstract

The invention provides a fine water mist water fire extinguishing agent. The water fire extinguishing agent is characterized by containing a first fire extinguishing composition and a second fire extinguishing composition. The fire extinguishing time and the recrudescence resisting time of the water fire extinguishing agent are largely improved through the water drop anchoring effect and the paving effect generated by electrostatic attraction between polymer additives with opposite charges; and meanwhile, the water fire extinguishing agent is better than most water fire extinguishing agents in the prior art in degradability, and is lower in environmental protecting influence.

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...
