摘要： Inert and hydrocarbon gases, such as propellant gases, maintain a pressure in a bottle to ensure that a formed composition can be dispensed to an intended destination. The carrier releases soluble hydrocarbon gases and the water drops dissolve inert gases, so the liquid is inflated and creates upstanding foam. This foam maintains the texture and water content up to 6-24 hours, depending on the ratio of the fire-resistant component. As heat reaches the foam, the heat-resistant silicate component becomes activated. Strong heat causes evaporation of the moisture of the carrier, and then the bound water of the silicates evaporates from the foam, with a honeycomb-structure left behind which is a good thermal insulator and is able to protect the object. Above approximately 350° C., a ceramic protective layer forms, while the water content of the foam inside the foam migrates outwards towards the dry crust.

摘要： The invention relates to nitrogen-generating compositions for saturation fire-extinguishing and to methods for producing same. The composition comprises: 25.0-45.0% by mass of a heavy metal oxide, 12.0-18.0% by mass of a combustion modifier in the form of aluminium oxide modified with cobalt (II) nitrate (Co(NO3)2), with accelerating additives of nickel oxide and copper oxide, with an alkali metal azide making up the remainder to 100% and 0.07-2.0% by mass of a carboxylic acid ester as moistener (residue after drying) above 100%. The composition is produced by mixing aluminium oxide with cobalt nitrate and with the moistener, allowing the mixture to stand and dry out so as to produce a first mixture, separately mixing the first mixture with the heavy metal oxide and the moistener until a second mixture is produced, separately preparing a mixture of alkali metal azide powder with the moistener until a third mixture is produced and then mixing the second mixture and the third mixture simultaneously with copper oxide and nickel oxide, drying out the produced mass and forming granules.

摘要： The present invention relates to a fire-extinguishing composition containing an alcohol/phenol compound and its derivative. The fire-extinguishing composition releases a great quantity of active fire-extinguishing particles by making use of the heat generated from combustion of a pyrotechnic agent. The fire-extinguishing composition containing an alcohol/phenol compound and its derivative in the present invention reacts at a high temperature to generate a great quantity of nanoscale active fire-extinguishing particles, takes reaction with one or more of O-, OH-, H-free radicals necessary for a chain combustion reaction, so as to cut off the chain combustion reaction and take physical and chemical inhibiting effects to jointly achieve a fire extinguishing effect at the same time. Meanwhile, it takes a synergistic interaction effect with pyrotechnic agent to further raise the fire extinguishing efficiency of the fire extinguishing agent and greatly shorten the effective fire extinguishing time.

摘要： A metal-carbonyl-containing fire extinguishing composition comprises metal carbonyl complexes. The fire extinguishing composition uses a pyrotechnic agent as a heat source and a power source. A high temperature in combustion of the pyrotechnic agent enables the fire extinguishing composition to decompose or react under heat; produced fire extinguishing substances are sprayed out together with the pyrotechnic agent, thereby achieving a fire extinguishing objective. In the fire extinguishing composition, by selecting preferable components and optimizing contents of the components, an optimum formula of the fire extinguishing composition is determined, thereby greatly improving the efficacy of the fire extinguishing composition. In addition, efficacies of the components in the fire extinguishing composition are fully utilized, which improves an effective utilization rate of the fire extinguishing composition.
