Abstract
The invention discloses a fire extinguishing agent which consists of the following components in percentage by weight: 5-40% of at least three kinds of salt containing carbonate, bicarbonate, ammonium, nitrate or nitrite, 5-20% of phosphate, 3-15% of active agent and the balance of water. In the invention, with the components such as at least three or more kinds of salt containing carbonate, bicarbonate, ammonium, nitrate or nitrite, polyphosphate and active agent, when the fire extinguishing agent is applied to a fire scene, some components react at low temperature to absorb heat and generate inert gases and realize the functions of cooling and isolating oxygen; along with the heat absorption of the fire extinguishing agent, the components needing relatively high temperature start reaction to further absorb heat and generate inert gases and realize a continuous fire extinguishment effect of the fire extinguishing agent; and meanwhile, through the components such as phosphate and active agent, an effect of covering the burning materials and retarding flame is realized.
Description
Technical field
The invention belongs to technical field of fire control, particularly relate to a kind of content extinguishing chemical for fire extinguisher.
Background technology
Extinguishing chemical mainly includes three classes, respectively powder extinguishing agent, carbon dioxide extinguishing agent and fire foam, and wherein carbon dioxide extinguishing agent is because preparation cost is high, but traceless feature after fire extinguishing, it is mainly used in the fire of the valuables such as electric, instrument; Fire foam is mainly used in putting out a fire to save life and property and is unsuitable for the fire such as the oil product put out a fire with water, and powder extinguishing agent is applicable to some small-sized fire. But the composition of these three extinguishing chemical is substantially single, such as powder extinguishing agent is to be covered on comburant by non-combustible matter to make flame suffocate; Carbon dioxide extinguishing agent is to carry out the mode of starvation by carbon dioxide to reach the purpose of fire extinguishing, and same fire foam is also by starvation and covers the foam not fired in combustible substance and realize fire extinguishing.
But when fire formula is bigger, the temperature in the scene of a fire quickly raises so that some incombustible also are able to burning at a certain temperature, so, the fire-fighting efficiency of single extinguishing chemical is relatively low, it is necessary to substantial amounts of extinguishing chemical could be put out a fire, and to fire fighter, the transport of extinguishing chemical is brought bigger burden.
Being found by scientific research, effectively reduce the temperature in the scene of a fire, the efficiency improving extinguishing chemical is improved a lot, therefore, the fire extinguishing of science should include reducing the temperature in the scene of a fire, starvation and cutting off comburant to realize quick extinguishing.
Reduce fire scene temperature, by studying, by extinguishing chemical in fire extinguishing procedure, it it is the effective way reducing fire scene temperature by the endothermic reaction, therefore, exploitation reaction equation extinguishing chemical, in the scene of a fire, the endothermic reaction is there is by extinguishing chemical, release noble gas and generation non-combustible matter are covered in combustible substance simultaneously, it it is the research direction of existing extinguishing chemical, technology is now also had to propose this type of extinguishing chemical, such as CN201310302230.9, what claim is a kind of throwing type fire annihilator and preparation method thereof, extinguishing chemical in this technical scheme is to pass through fluorine surfactant, potassium carbonate, ammonium sulfate, carbamide, APP, anion surfactant, sodium lauryl sulphate and water composition, this technical scheme is to be dissolved in above-mentioned each composition in the water of uniform temperature preparing extinguishing chemical, the advantage of this extinguishing chemical is to pass through potassium carbonate, ammonium sulfate, carbamide, APP, anion surfactant, sodium lauryl sulphate is when running into flame, decompose such as nitrogen, ammonia and carbon dioxide etc. go out noble gas, realize starvation, and said components can absorb substantial amounts of heat when decomposing, effectively reduce the temperature of flame, and generate non-combustible matter and surfactant and sodium lauryl sulphate generation foam, the surface being covered in combustible substance realizes fire-retardant.
But the extinguishing chemical of this technical scheme still has following weak point, first weak point is to need hot water in preparing, and in the process of breaking out of fire, the source of hot water can be affected, and then has influence on the efficiency of extinguishing chemical; Second weak point is, in this extinguishing chemical, the decomposition temperature of each composition is higher, and only when fire formula is bigger, the efficiency of extinguishing chemical just can embody, and when fire formula from the beginning of time, the effect of extinguishing chemical is not high.
