Abstract

The raw material composition of the invented high-concentration aqueous film-forming foam extinguishing agent includes fluorocarbon surfactant, hydrocarbon surfactant, organo-silicon surfactant, stabilizing coupler, chelating agent, spreading burn-resisting agent, bacteriostatic agent and water. It can be used for quickly extinguishing oil fire.

Description

Technical field: [0001] The invention relates to a foam fire extinguishing agent, in particular to a foam fire extinguishing agent with high concentration, which can mix and foam with seawater or fresh water at a ratio of 1:99 at a low temperature of -17°C, and efficiently extinguish oil fires. Background technique: [0002] The fire extinguishing agent used to extinguish oil fires at home and abroad is mainly foam fire extinguishing agent, and the aqueous film-forming foam fire extinguishing agent (AFFF for short), because the foam layer produced by it can spread and form a film on the oil surface, it can quickly burn the burning oil. The surface is extended to cover and isolate the air, so as to quickly extinguish the fire. And because the main components of the aqueous film-forming fire extinguishing agent and the auxiliary agent added are non-toxic and non-polluting, it is an environmentally friendly product. Therefore, the aqueous film-forming foam fire extinguishing a...
