Abstract (en)
[origin: WO2022169918A2] Environmentally-clean fire inhibiting and extinguishing dry powder compositions and products for sorbing flammable liquids while inhibiting ignition and extinguishing fire involving flammable hydrocarbon liquids such as, oils, fuels and non-polar solvents such as ketones and alcohols. The dry powder chemical compositions are made by mixing, blending and milling to suitable powder particle sizes, the following components: a fire extinguishing agent in the form of at least one alkali metal salt of a nonpolymeric saturated carboxylic acid; a powder fluidizing agent to help provide the dry powder composition with excellent fluid flow characteristics; and an oleophilic/hydrophobic composition for absorbing liquid hydrocarbons, while repelling water. A surfactant may be added to promote the formation of anhydrous semi-crystalline metal mineral salt film onto the surface of flammable hydrocarbon liquids involved in fire outbreaks to be extinguished and preferably absorbed by the dry powder chemical compositions.
