Abstract

L'invention concerne une mousse efficace pour combattre un incendie de liquide hydrophile ou polaire tel que les alcools inférieurs, des cétones, etc. La mousse de l'invention est obtenue à partir d'un concentré contenant un agent épaississant thixotrope dissous en grande quantité, dont la viscosité reste acceptable notamment sous agitation. L'hétéropolysaccharide-7 ou ses formes à chaîne modifiée conviennent à cette fin. Le concentré peut aussi être préparé sous une forme qui convient pour combattre des incendies de liquides hydrophobes, par addition de surfactants qui entraînent la formation d'une pellicule aqueuse sur ces liquides.Disclosed is a foam effective in fighting a hydrophilic or polar liquid fire such as lower alcohols, ketones, etc. The foam of the invention is obtained from a concentrate containing a thixotropic thickening agent dissolved in large quantities, the viscosity of which remains acceptable, in particular with stirring. Heteropolysaccharide-7 or its chain modified forms are suitable for this purpose. The concentrate can also be prepared in a form suitable for fighting fires of hydrophobic liquids by the addition of surfactants which cause the formation of an aqueous film on these liquids.
