Title Study on the fire extinguishing of perfluorinated surfactants water-based additives

Abstract This paper introduces the kinds of water extinguishing agent, compares the in water base extinguishing agent adding perfluorinated surfactant with common hydrocarbon surfactants effect on the fire extinguishing performance。 The results show that perfluorinated surface active agent than hydrocarbon surfactants for water-based fire extinguishing performance of larger, perfluorinated surface active agent is better。 Formula of water-based extinguishing agent were studied by the orthogonal test, formulation selected surface active agent, urea, diammonium phosphate, ammonium carbonate, disodium EDTA, ethylene glycol, polyethylene glycol (PEG) seven substances as additives, which the proportion of various additives were 6:6:3:3:6:4:2。 In accordance with the national standards for preparation of water-based fire extinguishing agent of the technical performance testing of various aspects and fire extinguishing experiment。 The results showed that the water base extinguishing agent is fully in line with the state regulations of the technical requirements and fire extinguishing performance。
