Description
Technical field
The present invention relates to a kind of high viscosity explosives, and in particular to a kind of high-viscosity glue shaped explosive charge and preparation method thereof.
Background technology
Explosive is a kind of substance that quickly can be burnt or decompose, and a large amount of heat can be generated in very short time
And gas, typical explosive include integrally explosive and corresponding apparatus to cause bursting, usually also have corresponding shell, are by thunder
After heat or the impact energy triggering of pipe, explosive will be chemically reacted quickly, i.e. fully burning or decomposition.In chemistry
In reaction, compound, which is decomposed, generates multiple gases, between each not homoatomic of reactant (original chemical compound), to change
It learns key-shaped formula and stores big energy, when compound molecule decomposes, product (gas of generation) is possibly also with some of which
Energy (rather than whole energy) forms new keys.The energy of most of " residues " can form high temperature heat, and the gas of concentration is in pole
Rapid expanding under big pressure, heat can accelerate the movement velocity of each gas particle so that pressure higher, in high explosive,
Gas pressure is very big, it is sufficient to destroy building, cause people's injures and deaths.If gas expansion speed is faster than velocity of sound, powerful rush just will produce
Wave is hit, this pressure can also promote solid fragment high speed to go out, and people or building are hit with huge strength.
Explosive because its with it is of low cost, save manpower, engineering construction can be accelerated, because due to it is more and more extensive be applied to state
The economic each department of the people.In terms of mining, Large-scale blasting is carried out using explosive, to exploit metallic ore and open coal mine；Profit
The petroleum perforation charge that explosive is loaded with energy-gathering jetting effect, can be used for oil exploitation；In terms of geological prospecting, made of explosive
Explosive-source explosive post is used for seismic prospecting；In machine building industry, explosive is used for explosive forming, the techniques such as cutting metal, explosive welding；
In hydraulic and electric engineering engineering, explosive is for building dam, dredging river, leveling land；In railway, highway construction, explosive is for splitting
Mountain is opened a way, and tunnel, chamber etc. are dug；Explosive is also largely used to exploit various building stones.Explosive militarily can be used as shell, aviation
The explosive charge of the ammunitions such as bomb, guided missile, land mine, torpedo, grenade, it can also be used to the apparatus to cause bursting and military blasting of nuclear bomb.
Industrially it is widely used in digging up mine, builds the road, build water conservancy projects, engineering explosion, intermetallic composite coating etc., is also widely used for seismic prospecting
Etc. science and technology fields.
In civil explosive industry now, in order to ensure the safety used, the ingredient of explosive is relatively stablized, but it is positive because
It is explosive using more and more extensive, therefore needs in certain specific techniques or use it with a variety of different characteristics, than
As some explosives need certain water-resistance, for another example some explosives to need higher viscosity, be convenient at specific processing in this way
Reason, while the stability of explosive is improved, extend its storage period, therefore, for the different performance requirement of explosive, needs to carry out it
It is correspondingly improved.
