The green environment-friendly water-based extinguishing agent adopts C6 series fluorocarbon surfactant as a key raw material, and does not produce any substances harmful to the environment after being used; the deionized water does not contain ionic components, so that the shelf life of the water-based fire extinguishing agent can be prolonged.
Description
Technical Field
The invention belongs to the technical field of water-based extinguishing agents, and particularly relates to a green environment-friendly water-based extinguishing agent.
Background
The water-based fire extinguishing agent is added with additives in water to increase the fire extinguishing function of the water. The water solution of the water-based fire extinguishing agent is filled with a large amount of gas through chemical and physical actions to form countless bubbles which cover the surface of the flammable liquid, so that on one hand, the heat of the liquid is captured, the temperature of the liquid is reduced, on the other hand, the foam has certain viscosity, the flammable liquid is not easy to contact with air, and the purpose of extinguishing fire is achieved. The fluorocarbon surfactant is an essential additive in the water-based fire extinguishing agent. In the prior art, the chemical formulas of fluorocarbon surfactants all contain 8 carbon atoms, and perfluorooctane sulfonyl compounds (PFOS) and perfluorooctanoic acid (PFOA) are generated after the fluorocarbon surfactants are used. PFOS is the most recalcitrant organic pollutant, and has been extensively limited in export product materials; PFOA has carcinogenic activity and is already among the class 2B carcinogens list. Therefore, there is a need for an environmentally friendly water-based fire extinguishing agent that does not generate PFOS and PFOA after use.
