HEAT-ABSORBING MATERIAL FOR COOLING HIGH-VELOCITY GAS AND AEROSOL STREAMS Russian patent published in 1998 - IPC

FIELD: heat-absorbing materials. SUBSTANCE: this material is particularly used for reducing temperature of gas-aerosol burning products of fire-suppressing compounds. Material has inorganic binding component in amount of 15-30 mass %, pore- and/or framework-creating additives, and chemical heat-absorbing agent in the form of at least one crystal hydrate of non-toxic salt of metal containing not less than 20 mass % of water. Content of additive in compound is 5-30 mass %. Usable as binding components are clays individual or in mixture with gypsum or cement. Usable as pore-creating additive is ammonium chloride or porofor, and used as framework-creating additive is magnium hydrocarbonate. At location of formed material in body of model generator, recorded was reduction of temperature from 1800-1900 C down to 500-600 C at 10 mm distance from end part of generator and down to 250-35- C at 100 mm distance. EFFECT: high efficiency. 6 cl
