Cheng Zhong, fin play the role of stabilized flight, and fin has deceleration system concurrently so that are slowed down when fire extinguisher bomb spraying fire-extinguishing agent.
Wherein the preparation method of solid carbon dioxide extinguishing chemical is by following steps：
Step 1：Aerosil HB-630 is handled using hexamethyldisilazane (HDMS), forms hydrophobic gas phase
Silica, a kind of this high-purity white powder.
Step 2：Surfactant is added into deionized water, until solute all dissolves.
Step 3：With electronic balance weighing silica and aqueous solution with 1:20 ratio be (silica and solution quality
Than), it is added into high speed agitator stirring a period of time.
The mechanism of action of solid carbon dioxide extinguishing chemical is described as follows：
When solid carbon dioxide extinguishing chemical in the present invention is put out a fire, due to being heated, original stable state is broken, the water in extinguishing chemical
Divide and release, reduces the temperature of comburant, make it that burning point be not achieved, while SiO 2 powder can be attached to comburant
Surface plays the role of completely cutting off oxygen in air, and the surfactant of addition can decomposite free amino, can be fired with flame
The OH free radicals burnt in reaction combine, and reduce and terminate the free radical of combustion reaction generation, reduce the reaction rate of burning.Cause
This, solid carbon dioxide extinguishing chemical has physics cooling and organoselenocyanate under detonation, has shock wave fire extinguishing feature, composite fire extinguishing concurrently
Ability is strong.Solid carbon dioxide extinguishing chemical can put out closed space on fire, also can be suitably used for the local fire extinguishment of open area.
The present invention has the following advantages：

For carbon solid fire, combustible liquid fire, fuel gas fire, electrification burning fire.Solid carbon dioxide extinguishing chemical is by gas phase titanium dioxide
Silicon and water are mixed according to a certain percentage, and the obtained high covering property of solid carbon dioxide extinguishing chemical water content is good, and mobility is small, and table is added
Face activating agent rear stability enhancing.
(2) shell of explosive snuffing bullet uses modified ABS plastics, fin to use high density polyethylene (HDPE), explosion in the present invention
It not will produce lethal fragmentation afterwards and personnel and instrument caused to damage.
(3) the bullet portion of explosive snuffing bullet is short and mellow and full in the present invention, and single tail is slightly long and is tapered, and this structure is advantageous
In reducing air drag, flight stability is improved.
(4) fin of explosive snuffing bullet is arranged symmetrically in the present invention, can be increased and be played head weight, reduces Quality of Tail.
(5) the powder charge pipe of explosive snuffing bullet uses the ladder-like charge constitution of transition type in the present invention so that solid carbon dioxide extinguishing chemical
When shedding be in inverted pyramid shape, most of extinguishing chemical radially and slightly downwards shed trend, advantageously form flat
Cloud and mist, it is more preferable compared with traditional charge constitution extinguishing effect.
(6) the solid carbon dioxide extinguishing chemical in the present invention not only can in a fire quickly, efficiently put out burning things which may cause a fire disaster, but also can also absorb
The gases such as carbon dioxide, carbon monoxide in air prevent dense smoke from being played effectively to the interference for the personnel that put out a fire to purify air
Ground acts on.
(7) the ratio dose of explosive snuffing bullet is 1.2%~1.6% in the present invention, commonly uses the best of forest big gun fire extinguisher bomb
It is 2% than dose, but the shell of forest big gun fire extinguisher bomb is metal-back, explosive snuffing body material is adopted in patent of the present invention
With ABS plastic and high density polyethylene (HDPE), therefore dose is suitably reduced, best results in preferably 1.2%~1.6% range.
(8) the explosive snuffing bullet fire extinguishing procedure in the present invention includes physics and chemical process：Water in solid carbon dioxide extinguishing chemical exists
Absorption heat can be evaporated after being crushed under intense shock wave effect, reduces the temperature of scene of fire；The surfactant that is added in liquid or
Other chemical addition agents can block combustion reaction chain.
