Problems solved by technology

[0002] Various additives are added to water-based fire extinguishing agents, and the surfactants added are usually relatively stable, but during long-term storage, the surfactants are also prone to hydrolysis, which will cause the water to harden
It is more common to add ethylene glycol as a pour point depressant in water-based fire extinguishing agents. The more ethylene glycol is added, the more the freezing point of the system will be lowered. It has the effect of supporting combustion, not only will not extinguish the fire, but will also increase the intensity of the fire
[0003] In the existing water-based fire extinguishing agents, the amount of ethylene glycol is generally controlled within 15%, and a large amount of inorganic salts are added to obtain a fire extinguishing agent with a lower freezing point. This method adds many types of inorganic salts and requires the addition of various additives In order to obtain a transparent and storage-stable fire extinguishing agent, if the content of ethylene glycol is increased, the fire extinguishing efficiency will be poor due to the combustion-supporting effect of ethylene glycol. At the same time, the addition of ethylene glycol will also make the inorganic salt easy to precipitate
In addition, the existing water-based fire extinguishing agents cannot efficiently extinguish the initial fires of Class A combustible solids, Class B combustible oils, Class C combustible gases, and live equipment below 1000V at low temperatures, and there are limitations in use
