The results of the development of a new universal fire-extinguishing agent with wetting, foaming and flame retardant properties
Wetting agents and foaming agents currently used in the fight against forest fires, do not have flame-retardant properties and can not provide non-combustible properties for forest combustible materials processed by them for longer than 24 hours. At the same time, the compositions of the long-term impacts of having high fire-extinguishing ability despite the content of a certain amount of surfactants, can wet forest combustible materials very bad and can not create foam. During the patent search it was found that universal extinguishing agents with high wetting and foaming properties and at the same time having ability preventing a burning of forest combustible materials more than 1 day - had not proposed currently. The result of this work created a new universal fire-extinguishing agent having wetting, foaming agent and flame-retardant properties. A technical specification containing the requirements for the new universal fire-extinguishing composition and its solutions, and its technical and operational characteristics has been developed. In 2015 the optimal recept were selected and a sample of the new universal fire-extinguishing composition in the form of a liquid concentrate was made in the laboratory. Experiments to determine the necessary characteristics, as well as full- scale field tests confirmed that the parameters of the new composition meets the requirements of the technical specifications and it can be used in the fight against forest fires. Comparative data showing that the main technical parameters of the universal fire-extinguishing agents are on the level of the best existing samples are presented. It is noted that new fire extinguishing chemical has a very high ability to stay on combustible forest materials and its main advantages are considered.
