The object of the present invention is to provide a kind of forest extinguishing that is suitable for, the effective dry chemical powder extinguishing chemical of putting out a fire.
Solution of the present invention is that to set about said dry powder from the composition that changes the dry powder chemical extinguishing chemical and micrograined texture be not fine pressed powder, is 0.5～1.5 millimeter dry powder particle but make a kind of particle diameter.Said dry powder particle has a centronucleus that accounts for particle total amount 80～85%, also has a clad on the centronucleus surface.For preventing that dry powder from producing caking phenomenon in storing, and also is added with 0.5～2%(weight % in the dry powder) anticaking agent.It is loose that the powder extinguishing agent of making like this can keep in storage, good fluidity.
The centronucleus that an important feature of the present invention is said dry powder particle is made up of acid ammonium phosphate salt and ammonium sulfate, and both ratios are 1.2～1.5: 1.Wherein the content of acid ammonium phosphate salt accounts for 45～50%(weight % of particle total amount).And the content of ammonium sulfate accounts for 35～45% of total amount.
The clad of said dry powder particle wherein contains compositions such as barium sulfate, silica, trichloro-ethylene, silicones, dibutyl tin dilaurate and pigment.Its content ratio is: barium sulfate accounts for 44～47%, and silica accounts for 30～37%, and trichloro-ethylene accounts for 10～15%, and silicones accounts for 5～10%, and dibutyl tin dilaurate accounts for 0.3～1%, pigment a little.So just constitute extinguishing chemical dry powder particle of the present invention, this particle grain size is 0.5～1.5 millimeter and preferably is controlled at 0.8～1.2 millimeter.This dry powder particle increases greatly than the weight of common dry powder attritive powder, is generally 1.5～2 milligrams/.For preventing that powder extinguishing agent from luming in storing, the present invention is an anticaking agent with a kind of talcum powder and mica powder mixture, and both ratios are 1: 1, so just constitute said fire-extinguishing agent for forest.
The production stage that the present invention prepares fire-extinguishing agent for forest comprises:
(a) barium sulfate, silica, trichloro-ethylene, silicones, dibutyl tin dilaurate and pigment are mixed in proportion, under agitation heat gel, gelatinization temperature is controlled at 90～110 ℃, makes covering.
(b) acid ammonium phosphate salt and ammonium sulfate are pulverized, made granularity less than 0.1 millimeter, fully mix in proportion, mix the medicine temperature and be not higher than 70 ℃, the centronucleus of dry powder particle is made in granulation thereafter.
(c) under constantly stirring, the covering that (a) made takes advantage of heat to join equably on the centronucleus that (b) step makes, and makes centronucleus wrap one deck clad, and mixed medicine temperature is about 60～70 ℃.
(d) add anticaking agent at last
Can be mixed with particle diameter by the manufacture method of fire-extinguishing agent for forest provided by the invention is 0.8～1.2 millimeter, and particle weight is 1.5～2 milligrams/a graininess powder extinguishing agent, uses in the portable forest extinguishing device that CN912315059 provides.The particle powder extinguishing agent is drawn in the injector, from the nozzle ejection, sprays to the scene of a fire together with the air of suction.Because dry powder particle diameter of the present invention is big, every dry powder is easy to enter the burning things which may cause a fire disaster root than great under the propelling of injector air stream.The impulsive force of dry powder particle also plays a suppression fire extinguishing effect to flare, has improved fire extinguishing and has renderd a service.Dry powder is pressed close to after the burning things which may cause a fire disaster root, activity-NH under flame because in the centronucleus
2The initiation reaction of base, dry powder particle is blasted once more and is emitted a large amount of gases, and forms flame-out separation layer at the burning things which may cause a fire disaster root, plays effective fire extinguishing effect.
The extinguishing chemical that the present invention is mixed with can also be made a kind of fire extinguisher bomb, is used for fire extinguishing with delivery mode.For example use a paper web packaging bag, every the 0.5 kilogram of medicament of packing into, the fire extinguisher bomb of launching during use, in the flame sky, paper web is burnt to break, and the dry powder particle of the inside relies on the gravity of self to scatter on the burning things which may cause a fire disaster, forms the fire extinguishing separation layer, produces the fire extinguishing effect.Certainly can also make fire extinguisher bomb with additive method.
Done fire extinguishing effectiveness mensuration according to the professional standard ZBC84006-87 of People's Republic of China (PRC) regulation.Do the fire attack test with the portable forest extinguishing device of CN91231505.9 and extinguishing chemical of the present invention, 15 ℃ of environment temperatures, wind speed is greater than 5 meter per seconds, and jet length can reach 7～8 meters, is 100% to the rate of putting out of A, category-B fire.
The invention will be further described to use a concrete instance below again.
In a reactor, drop into 46 kilograms in barium sulfate, stir down and drops into 31 kilograms in silica respectively, 14.6 kilograms of trichloro-ethylenes, 8 kilograms of silicones, 0.4 kilogram of dibutyl tin dilaurate and red pigment a little.Be heated to 100 ℃, 100 kilograms of said coverings are made in gel under agitation 80 minutes.
