Abstract

Purpose. To study of the dependence of the surface tension of fluorinated surfactants of various chemical nature on their concentration and determine the most suitable fluorinated surfactant for use in film-forming foam concentrates.

Methods. The surface tension of the solutions was measured using a KRÜSS K20 automatic tensiometer using the Du Noüy ring method described in ISO 304. The determination of the critical micelle concentration of surfactant solutions in aqueous systems was carried out according to the State Standard 29232-1991.

Findings. The results of research of the surface tension of aqueous solutions of anionic, nonionic and amphoteric fluorinated surfactants from various manufacturers are presented. The most promising fluorinated surfactants and co-solvents being used as a part of film-forming foam concentrate for fire extinguishing have been established. The choice of a fluorinated surfactant for the creation of a targeted foaming agent, which makes it possible to obtain an aqueous film on the surface of n-heptane, is substantiated.

Application field of research. The results obtained can be used in the development of a formulation of a targeted foaming agent for extinguishing fires.
