Description

Technical Field

[0002] Foam fire extinguishing agent is an effective fire extinguishing agent for extinguishing flammable and combustible liquids. It mainly generates a condensed foam floating layer on the surface of the liquid, which has a suffocating and cooling effect. Foam fire extinguishing agent is divided into chemical foam, air foam, fluoroprotein foam, water film-forming foam and anti-soluble foam.

[0003] Plant-based composite flame retardant fire extinguishing agent is a multifunctional and multi-purpose composite flame retardant fire extinguishing agent made of water, natural plants and wood ash as the main raw materials together with combustion aids. It can achieve the purpose of safety and protection of human environment while achieving flame retardant and fire extinguishing. Plant-based composite flame retardant fire extinguishing agent is completely different from other fire extinguishing agents. Its technical breakthrough is to use biochemical and physical and chemical principles and technologies to produce flame retardant activity, forcing the combustion properties of the burning material to be fundamentally changed, changing it from flammable to difficult to burn and non-flammable, thereby achieving the purpose of fire extinguishing.
