Title (EN) FIRE SUPPRESSANT COMPOSITIONS
(FR) COMPOSITIONS D'EXTINCTION D'INCENDIES
Abstract:
(EN) Fire suppressant compositions which are substantially free of ammonium nitrate and which comprise potassium nitrate in an amount sufficient to generate at least about 10 wt.% potassium carbonate when combusted. Most preferably, a guanidine salt, such as guanidine nitrate, is used in combination with the potassium nitrate. The compositions employed in the present invention have low pressure exponents, high burning rates and low flame temperatures.
(FR) L'invention concerne des compositions d'extinction d'incendies sensiblement sans nitrate d'ammonium et qui comprennent du nitrate de potassium en quantité suffisante pour générer au moins environ 10 % en poids de carbonate de potassium en combustion. De préférence, un sel de guanidine tel que le nitrate de guanidine est utilisé en combinaison avec le nitrate de potassium. Les compositions utilisées dans la présente invention présentent des exposants à basse pression, de grandes vitesses de combustion et des températures à faible inflammabilité.
