| 摘要 |
The present invention relates to a fire extinguishing composition producing fire extinguishing substance by high temperature sublimation, the fire extinguishing composition comprising a fire extinguishing material which, in a heating process, can sublimate and release a fire extinguishing substance with fire extinguishing properties, the content of the fire extinguishing material being at least 80% by mass. When the fire extinguishing composition is in use, a pyrotechnic composition is used as a heat source and power source; by first igniting the pyrotechnic composition, the high combustion temperature of the pyrotechnic composition causes a large quantity of fire extinguishing substance to be produced by the fire extinguishing composition which is sprayed out together with the pyrotechnic composition and thus achieves the purpose of fire extinguishing. When compared with traditional aerosol fire extinguishing systems, gas fire extinguishing systems and water type fire extinguishing systems, the present invention can provide a more efficient and safer fire extinguishing composition. |
