Abstract

The invention relates to a water-series fire extinguishing agent and belongs to the technical field of firefighting. The water-series fire extinguishing agent comprises 0.5%-5% of inorganic salt, 0.1%-1% of surfactants, 0.5%-2% of foaming agents, 1%-20% of fire retardants, 10%-20% of antifreeze agents, 0.1%-1% of penetrating agents, 1%-2% of emulsifying agents and 65%-85% of water. The water-series fire extinguishing agent provided by the invention is low in cost, good in fire extinguishing performance, harmless to environment and people and wide in application range, and toxic and hazardous waste gas cannot be produced in the fire extinguishing process.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a water-based fire extinguishing agent. Background technique [0002] A new type of fire extinguishing agent that adds reagents to water or changes the physical properties of water to improve the fire extinguishing performance of water is called water-based fire extinguishing agent. Water has a strong ability to absorb heat and has a significant cooling effect on burning substances. Water vaporization produces a large amount of water vapor, which displaces and prevents air from entering the combustion zone, and can reduce the oxygen content in the combustion zone. In addition, water is cheap and easy to obtain, with a wide range of sources and no pollution to the environment. Therefore, water has become the most important fire extinguishing agent for fighting fires. However, water also has obvious deficiencies. Due to the good fluidity of water, most of the water will b...
