FIRE-EXTINCTION PROPERTY OF AEROSOLS OF AQUEOUS SOLUTIONS OF COPPER (ІІ) CHLORIDЕ

Abstract

In article the results of laboratory experiments on a fire-extinction of a hydrocarbonaceous flame using aerosols of aqueous solutions of copper (ІІ) chloride of different concentration are demonstrated. The experiments have shown, that short-term effect of 40 % aerosol of an aqueous solution of copper(ІІ) chloride (CuCl2) on front of carbon flame causes its effective suppression, up to complete quenching. Minimum consumption volume of 40% of an aqueous solution of copper(ІІ) chloride on fire-extinction of ethanolamine flame is (0,80 l/m2). It is determined, in case of quenching of the burning hydrocarbons with the help of aqueous 40% aerosol CuCl2 the expenditure of this aqueous fire-extinction substance is 6,3 times (for ethanolamine) and 3,6 times (for hexane) less than standard expenditure of sprayed water.
