Physical-chemical explanation of fire-fighting efficiency of FHF (fast-hardening foam) based on structured silica particles

Report is dedicated to thermophysical and chemical explanation of the ways of increasing the fire-extinguishing process of solid combustible materials. As a result of research such indicators are obtained as speed of extinguishing, specific consumption, IFFE (index of fire-fighting efficiency) with help of fast-hardening foam. Fire-extinguishing mechanisms of fast-hardening foam are considered and evidences of their positive features are given. Application areas of fast-hardening foam are pointed. At the Fig. 1 thermal insulating capabilities of the fast-hardening foam, which hinder the flame to impact on opened parts of body are clearly presented.
