[0002] Aqueous film-forming foam (AFFF) is a foam extinguishing agent based on hydrocarbon and fluorocarbon surfactants that can form a water film on the surface of certain hydrocarbon liquids. It is suitable for extinguishing fires caused by non-water-soluble liquid fuels. AFFF should be sealed in iron or plastic drums with a corrosion-resistant coating. AFFF should be stored in a well-ventilated, cool, and dry place; the storage temperature should be below 40°C and 5°C above the freezing point of AFFF.

[0003] However, existing devices suffer from low stirring efficiency, simple stirring rod structure, and limited stirring effect, which prolongs the stirring time and reduces production efficiency. Therefore, a stirring and mixing device for fluorine-free aqueous film-forming foam fire extinguishing agent is proposed. Utility Model Content
