Synergism and antagonism in the action of powder inhibitors on propane-air flames

摘要

Experimental data on the flame-extinguishing ability of multicomponent mixtures of powder inhibitors regarding propane-air flames are presented. It is demonstrated that mixtures exhibiting synergism and high flame-extinguishing ability can be used as the active component in fire-fighting powders (mixtures of potassium carbonate with sodium fluoride or sodium hydrocarbonate). The procedure for selecting the components of effective multicomponent mixtures is analyzed.
