Abstract
A fire extinguishing agent for ultralow temperature is disclosed. The fire extinguishing agent comprises following components by mass: 2-5% of perfluoroalkylsulfonyl quaternary ammonium iodide, 2-5% of fluoroalkylbetaine, 5-10% of decylalkylbetaine, 0.3-0.8% of xanthan gum, 5-10% of laurylimidazoline betaine and 40-60% of triethanolamine phosphate, with the balance being water. An application of the fire extinguishing agent for ultralow temperature is further disclosed. The fire extinguishing agent can rapidly extinguish fire and is suitable for ultralow-temperature environments.
Description
Technical field
The present invention relates to a kind of ultralow temperature extinguishing chemical.
Background technology
In prior art, because flame combustion temperature is higher, usual fire scene temperature reaches more than 1100 DEG C, and when fire foam is sprayed onto on ignition point, extinguishing chemical moment is evaporated, thus does not reach covering buffer action, impact fire extinguishing.Therefore, when need wait until that ignition temperature reduces, the foam ability stable existence that extinguishing chemical produces, could quick extinguishing.Described temperature reduces the evaporation of dependence moisture and absorbs heat, and cooling effect is bad, makes blow-off velocity slower.
Meanwhile, the extinguishing chemical of prior art is subzero 50 degrees Celsius time, and extinguishing chemical is solidified, and makes to be applicable to low temperature environment, and its adaptability is more weak.
Summary of the invention
The object of the present invention is to provide a kind of ultralow temperature extinguishing chemical, can quick extinguishing, and go for ultra-low temperature surroundings.
For reaching above-mentioned purpose, solution of the present invention is:
A kind of ultralow temperature extinguishing chemical, be made up of by mass percentage following component: perfluoro capryl Tetrumethylammonium Iodide compound 2%-5%, fluorinated alkyl betaine 2%-5%, ten alkyl betaine 5%-10%, xanthans 0.3%-0.8%, lauryl imidazolinium betaine 5%-10%, triethanolamine phosphate 40%-60%, surplus is water.
A kind of application of ultralow temperature extinguishing chemical, will by mass distribution ratio perfluoro capryl Tetrumethylammonium Iodide compound 2%-5%, fluorinated alkyl betaine 2%-5%, ten alkyl betaine 5%-10%, xanthans 0.3%-0.8%, lauryl imidazolinium betaine 5%-10%, triethanolamine phosphate 40%-60%, surplus is that the extinguishing chemical of water composition is mixed with the aqueous solution that mass fraction is 6%.
After adopting such scheme, the present invention, by adding triethanolamine phosphate, absorbs the photon discharged when burning, cut off luminous energy to thermal energy by way of, control the temperature of combustion reaction release from root, ignition temperature is reduced to below burning-point instantaneously, serves the extinguishing effect be exceedingly fast.Again by fully wetting infiltration emulsification combustible, forms thin film, reach starvation, nip off the object that the chain type rapidly response that burns is put out a fire in the middle of combustible with froth bed, blow-off velocity soon and not resume combustion.
Meanwhile, freezing point can be reduced to subzero 50 degrees Celsius by the triethanolamine phosphate added, and ensures, in low temperature environment, not freeze, and enhance the boisterous adaptability of extinguishing fluid, its adaptability is stronger.
