Abstract
The invention discloses a preparation method for dual-purpose forest fire extinguishing agents. According to the formula, the dual-purpose forest fire extinguishing agents include 50-100 parts of ammonium monohydric phosphate, 75-150 parts of disodium hydrogen phosphate, 15-30 parts of urea, 0-300 parts of calcium carbonate, 50-150 parts of ammonium carbonate, 1-5 parts of sodium dodecyl benzene sulfonate and 475-550 parts of water. According to the preparation steps, the raw materials are added into a reactor, mixed and stirred for 0.5-1 h, and obtained mixed slurry is injected into barrels and then sealed and packaged. The preparation method for the dual-purpose forest fire extinguishing agents has the advantages that the dual-purpose forest fire extinguishing agents can be directly sprayed for fire extinguishing or build a fireproof zone, and are prepared by mixing various agents with an excellent fire extinguishing effect, the fire extinguishing effect is good, and the fire extinguishing agents can be prepared in different proportions according to the forest fire behavior and then used for fire extinguishing.
Description
Technical field
The invention belongs to fire service inventory fire-fighting quipment field, the preparation method being specifically related to a kind of dual-purpose fire-extinguishing agent for forest.
Background technology
Forest fire is first of forest three the Nature disaster, it is prevented that fire conserves forests exactly. In forest fire, often as water source is rare and fetches water difficulty and lead to miss the best period of putting out mountain fire, therefore the importance of fire-extinguishing agent for forest becomes increasingly conspicuous. Fire-extinguishing agent for forest employs a lot of year in many countries, and American points out that cellulosic burning, pyrolysis, flameless combustion are maximally effective fire extinguishing reagent by ammonium phosphate, diammonium phosphate. In recent years, the research of fire-extinguishing agent for forest is paid attention to mixed effect that the formula to fire-extinguishing agent for forest improves with various fire extinguishing reagent mostly study, and in the use of fire-extinguishing agent for forest, existing fire-extinguishing agent for forest major part is mainly paid attention to the directly injection of forest fire is put out to have data to show, and the building research of fire guard is considerably less, therefore, injection method is used to stamp out a fire once out of control being not enough to of the intensity of a fire, fire extinguishing procedure will be produced huge pressure, the forest reserves and ecological environment are caused serious infringement. For this problem, research and develop and a kind of not only may be used for directly spraying fire extinguishing but also can the extinguishing chemical of Building Fire Protection band be significantly thing.
Summary of the invention
The present invention be directed to that forest fire provides a kind of not only may be used for directly spraying fire extinguishing but also can the extinguishing chemical of Building Fire Protection band, this extinguishing chemical extinguishing effect is excellent, it is possible to adopt different proportioning extinguishing chemicals to put out a fire according to the different forest intensity of a fire.
The technical scheme is that a kind of forest extinguishing chemical is made up of by following percentage by weight following various materials:
Diammonium phosphate 50-100 part
Disodium hydrogen phosphate 75-150 part
Carbamide 15-30 part
Calcium carbonate 0-300 part
Ammonium carbonate 50-150
Dodecylbenzene sodium sulfonate 1-5 part
Water 475-550 part.
Fire-extinguishing agent for forest of the present invention is prepared according to the following steps:
(1) diammonium phosphate of above-mentioned weight proportion, disodium hydrogen phosphate, carbamide, calcium carbonate, ammonium carbonate, dodecylbenzene sodium sulfonate, water are added reactor mix and blend 0.5-1 hour;
(2) mixed serum of gained in step one is carried out a point bucket perfusion;
(3) mixed serum of in step 2 point of bucket perfusion is carried out sealing packing processes.
The calcium carbonate content that fire-extinguishing agent for forest prepared by the present invention can pass through to regulate in component in forest fire uses flexibly. When there is forest fire, the extinguishing chemical containing low weight percentage calcium carbonate can be used to carry out ejecting extinguishing, using the fire extinguishing serosity Building Fire Protection band containing high percentage by weight calcium carbonate simultaneously. In use, ammonium carbonate decomposes discharges carbon dioxide and ammonia to extinguishing chemical prepared by the present invention, it is possible to starvation rapidly, and diammonium phosphate and carbamide have P-N to work in coordination with fire extinguishing function simultaneously, therefore have efficient fire extinguishing function; The existence of calcium carbonate can improve the adhesion property of extinguishing chemical, and dodecyl can accelerate the dispersion of these solid constituents, makes preparation time shorten; In extinguishing agent storage process, disodium hydrogen phosphate is dissolved in and wherein can form buffer solution, makes extinguishing fluid have stable pH thus ensureing the storage time.
Present invention is characterized in that the calcium carbonate content that can pass through to regulate in component is thus using flexibly, both the extinguishing chemical containing low weight percentage calcium carbonate can have been used to carry out ejecting extinguishing, the fire extinguishing serosity Building Fire Protection band containing high percentage by weight calcium carbonate can be used again, thus substantially increasing fire-fighting efficiency.
Detailed description of the invention
Detailed description of the invention one
(1) it is equipped with by following percentage by weight: diammonium phosphate 80 parts, disodium hydrogen phosphate 80 parts, 17 parts of carbamide, calcium carbonate 0 part, ammonium carbonate 75 parts, dodecylbenzene sodium sulfonate 1 part, 500 parts of water, adds reactor mix and blend 0.5 hour;
(2) mixed serum of gained in step one is carried out a point bucket perfusion;
(3) mixed serum of in step 2 point of bucket perfusion is carried out sealing packing processes.
Extinguishing chemical prepared by present embodiment is used for can be used for injecting type fire extinguishing.
Detailed description of the invention two
Present embodiment and detailed description of the invention one institute the difference is that: the percentage by weight of step one Raw is diammonium phosphate 75, disodium hydrogen phosphate 80, carbamide 17, calcium carbonate 300, ammonium carbonate 75, dodecylbenzene sodium sulfonate 5,550 parts of water, and other and detailed description of the invention one are identical.
Fire extinguishing serosity prepared by present embodiment can be used for Building Fire Protection band.
The present invention is not limited to above-mentioned embodiment, and all employings realize all technical schemes of the present invention with the same or similar method of the present invention and structure, all should in protection scope of the present invention.
