REGULARITIES FOR FIRE FIGHTING OF COMBUSTIBLE WATER-REPELLENT MATERIALS AND OIL PRODUCTS BY THERMO-FOAMING COMPOSITIONS

The aim is to reveal the fighting process regularities of the water-repellent solid combustible materials and oil products by the thermo-foaming compositions and to develop the fire-extinguishing agent compounding on their base. The physical-mathematical modelling and laboratory experiments have been carried out. The model for formation and failure of the foam layer under action of the heat flow has been developed. The mechanism for thermic formation and failure of foam has been described. The thermo-foaming composition parameters characterizing the thermic foam formation process have been proposed. The basic fighting regularities of the water-repellent combustible materials and oil products by thermo-repellent compositions have been revealed. The nature and content influence of the thermo-foaming composition components on its fire-fighting efficiency has been determined, and the conditions of using saturated hydrocarbons as the propellents in the thermo-foaming compositions have been determined. The thermo-foaming compositions for fighting of the water-repellent combustible materials and oil products have been developed. The trial-commercial batch of thermo-foaming composition has been made in the Scientific-Production Association of State Applied Chemistry Institute (St.-Petersburg)Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
