Modifying of air-mechanical foams using organosilicone compounds

Abstract

The results of studying the fire foams’ modification using organosilicone compounds are presented in this article. The results of comparative fighting flammable liquid fires (diesel fuel) using non-modified foam and modified foam are also studied. It is shown that fire fighting using foam, modified with organosilicone compounds is much more effective, because of the increasing isolating capacity of such foam due to high-solidifying formation of foam which prevent the liquid vapors from getting in the area of chemical reactions and also isolate the flammable liquid from the oxygen of the air. Such a result is possible due to the presence of the mixture of solutions of foaming agent and the organosilicone modifying compound in the structure of the foam – tethraethyl silicate (TES). The results of the study confirm the perspective of using the organic compounds of the silica for improvement the fire extinguishing properties of the foam and its further applying for the fighting with flammable liquid fire.
