FIRE EXTINGUISHING EFFICIENCY OF FOAMS BASED ON AQUEOUS SOLUTION OF SODIUM ALKYL SULFATES
Abstract
Fire extinguishing efficiency of low expansion foam based on aqueous solutions of sodium alkyl sulfates is investigated. Superficial activity of aqueous solutions of foaming agents on the border with heptane are researched and on the basis of these measurements it were calculated spreading coefficients of water solution on a heptane and a heptane on the solution. It is shown that the behavior of the foam received from solutions of alkyl sulfates in contact with burning heptane is considerably differs. It is established that fire extinguishing efficiency of homologs among sodium alkyl sulfates correlates with superficial activity of solutions of these SAS (surface-active substances) on a border with heptane and air.
