EXTINGUISHING OF THE MULTICOMPONENT COMPOSITE FUELS BY AQUEOUS FILM FORMING FOAM BY SUBLAYER WAY

It is shown that for suppression of the composite fuels by sublayer way we should use foaming agents which structure along with fluorinated stabilizers includes polymeric components. Results of laboratory researches on detection of the optimal concentration of foaming agent with polymeric component for sublayer extinguishing of the composite fuels are given. It is determined that concentration of foaming agent in a water solution exerts influence on the period of suppression and foam rate. It is also determined that thermal stability of foam grows in proportion to concentration of a polymeric component. As a result of researches it is offered the mechanism of a foam layer formation for sublayer extinguishing of the composite fuels.
