- Fire extinguishing composition for producing fire extinguishing substances by sublimation at high temperature
- the present invention relates to the field of fire protection, and relates to a fire extinguishing composition, the use of a chemical fire extinguishing substance, and more particularly to a fire extinguishing composition for producing a fire extinguishing substance by sublimation at a high temperature.
- Gas fire extinguishing systems, dry powder fire extinguishing systems and water fire extinguishing systems are widely used as substitutes for halon fire extinguishing agents because they are environmentally friendly.
- the extinguishing mechanism of carbon dioxide, IG541 and other inert gas fire extinguishing systems is mainly physical fire extinguishing.
- the fire extinguishing is suffocated by reducing the oxygen concentration in the fire zone. This kind of fire extinguishing method is easy to pose a threat to the personal safety of the personnel.
- the dry powder fire extinguishing system is operated by the pressurized gas. The sprayed powder is in contact with the flame, and physicochemical inhibition occurs to extinguish the fire.
- the water mist extinguishing system achieves the purpose of controlling fire, suppressing fire and extinguishing fire by the triple action of cooling by fine water mist, suffocation and heat radiation. .
- next-generation fire-fighting technology project team of the Center for Building and Fire Research of the American Institute of Standards and Technology has published many articles in this regard. They use nitrogen, carbon dioxide or CF 3 H gas as the carrier gas. These gases at high temperature heat the test substance and act on the flame together with the carrier gas to study the fire extinguishing ability of the test substance.
- some substances can be sublimated under the action of high temperature gas, which can produce fire extinguishing substances after sublimation, which can significantly improve the fire extinguishing efficiency of carrier gas (Proceeding of the Combustion Institute, Volume 28, 2000/pp. 2965-2972, Flame inhibition by ferrocene and blends of inert and catalytic agents, Halon Options Technical Working Conference 2-4 May
- the existing aerosol fire extinguishing agents mainly include S-type and K-type fire extinguishing agents.
- the existing aerosol fire extinguishing agents all use a fire extinguishing agent to generate a large amount of gas by redox reaction.
- the active particles through the chain scission reaction of the active particles, cover the suffocation of a large amount of gas, and achieve the purpose of combining fire and chemical.
- the aerosol fire extinguishing agent releases a large amount of heat at the same time as the combustion reaction releases the aerosol.
- the cooling system In order to effectively reduce the temperature of the device and the aerosol, and avoid secondary fires, the cooling system needs to be added, resulting in a complicated and cumbersome structure and complicated process flow.
- the high cost due to the existence of the cooling system, inactivates a large number of active particles, resulting in greatly reduced fire extinguishing performance.
- the fire extinguishing composition of the present invention comprises a fire extinguishing material which can be sublimed at a high temperature to produce a fire extinguishing substance, and the content thereof is 80% by mass or more.
- the fire extinguishing composition of the present invention can be used as a fire extinguishing material which can produce a fire extinguishing substance by high temperature sublimation as a main fire extinguishing material, and various additives commonly used in the art can be appropriately added.
- the fire-extinguishing composition capable of generating fire-extinguishing substances by sublimation at high temperature is sublimated into a flame-inhibiting substance upon heating, and the substance can be physically or chemically inhibited, or physically and chemically neutralized.
- the fire extinguishing composition is heated under high temperature, The heat absorption and sublimation can be quickly formed, the heat released by the pyrotechnics combustion can be effectively and quickly reduced, the temperature of the spout and the discharge material of the fire extinguishing device is greatly reduced, the complicated cooling system of the fire extinguishing device is eliminated, and the secondary fire is eliminated.
- the dangers; Fourth, the fire extinguishing composition is easy to process and form, and can be used alone or in combination with physical coolant; 5. Stable performance, easy to store for a long time; 6. Low toxicity or non-toxicity, excellent environmentally friendly performance.
- the fire extinguishing composition of the present invention comprises a fire extinguishing material which produces a fire extinguishing substance by sublimation at a high temperature and has a content of 80% by mass or more.
- the flame suppression mechanism of the fire extinguishing composition for producing fire extinguishing substances by sublimation at high temperature is as follows:
- the fire extinguishing composition can be sublimated into a gaseous flame suppressing substance at a high temperature, and the gaseous fire extinguishing substance can pass the reaction necessary for radical and chain combustion reaction.
- ⁇ One or more of OH., H. radicals react to cut off the chain combustion reaction, or reduce the partial pressure of oxygen by physical action to suppress the flame, or simultaneously achieve physical and chemical inhibition.
- the fire-extinguishing effect at the same time, produces a synergistic effect with the pyrotechnic agent, further improving the fire-extinguishing performance of the fire extinguishing agent and greatly shortening the effective fire-extinguishing time.
- the fire extinguishing material preferably has a melting point above 100 ° C, and may be: 2,4,6-tribromophenyl shrinkage Glyceryl ether, dinonyl tetrabromophthalate, pentabromobenzyl bromide, 2,4,6-tribromophenyl maleimide, pentachlorochlorocyclohexane, tris(2,3 -dibromopropyl)isocyanate, tetrachlorophthalic anhydride, hexachlorobenzene, hexachloroethane, melamine, cyanuric acid, red phosphorus, tin dioxide, ammonium bromide, ferrocene cobalt.
- the fire extinguishing composition of the present invention may further add various additives as needed, for example, it may be stearate, graphite, water-soluble high polymer compound solution or a mixture thereof, and the content is 20 mass or less. %.
- the components of the fire extinguishing composition of the present invention and the content thereof are preferably: fire extinguishing material: 80% by mass to 90% by mass,
- Additive 10% by mass to 20% by mass.
- the fire extinguishing composition of the present invention can be formed into a spherical shape, a sheet shape, a strip shape, a block shape, a honeycomb shape by a process such as pelleting, molding, extrusion, and the like, and can be subjected to surface coating treatment.
- a process such as pelleting, molding, extrusion, and the like
- it is preferred to add hydroxymethylcellulose or hydroxyethylcellulose as a surface coating agent.
- the surface coating agent can improve the surface finish of the composition system, and improve its strength, wear resistance and shock resistance, and prevent the occurrence of powdering of the fire extinguishing composition during transportation, slag dropping and overflow of the fire extinguishing device.
- the comparative example is that a fire extinguishing device sample containing only 20 g of a commercially available S-type aerosol fire extinguishing agent or a K-type aerosol fire extinguishing agent, respectively, is subjected to a distributed fire extinguishing test in the same 1.0 m3 test box, and each set of samples is tested. 3 rounds, record the amount of fire extinguishing and residual amount.
- the experimental test results are shown in Table 1.
- the fire extinguishing condition in the above table is the number of fire extinguishings of at least one of the three tests performed, and the residual amount is the average value of three experiments.
