Description
Technical field
The present invention relates to a kind of delay powders of delay detonating detonator, and in particular to a kind of delay detonating detonator
High precision tungsten type delay composition 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 explosive and corresponding apparatus to cause bursting, usually also have corresponding shell, be by detonator
After heat or impact energy triggering, explosive will be chemically reacted quickly, i.e. fully burning or decomposition.It is chemically reacting
In, compound, which is decomposed, generates multiple gases, between each not homoatomic of reactant (original chemical compound), with chemical bond
Form stores big energy, and 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.The gas of concentration is greatly being pressed
Rapid expanding under power, heat can accelerate the movement velocity of each gas particle so that pressure higher, in high explosive, and 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 shock wave will be generated.
This pressure can also promote solid fragment to go out at a high speed, with huge strength strike people or building.
Explosive is due to that can make surrounding medium fierce destruction work(, and be often otherwise known as high explosive, and common high explosive is pressed
Composition can be divided into 2 class of single compound explosive and composite explosives.Wherein, the very high explosive of also a kind of sensitivity, is changed into detonation from burning
Time it is extremely short, be usually not directly used for making destruction work(, but for igniting or igniting other explosive wastewaters, referred to as priming.It is fried
By the effect of certain extraneous excitation momentum, detonation is that the spread speed of chemical reaction zone in explosive is more than explosive for the explosion of medicine
Explosion phenomenon during the middle velocity of sound is the typical energy releasing pattern of explosive.Actually in two stages, most of destroy is for explosion
Caused by initial expansion, it can also manufacture a very low region of pressure around explosive source, and gas is quickly displaced outwardly, from
And from explosion, " " center " is inhaled outward, and outward after impact, gas regurgitates the central area of partial vacuum, shape by most of gas
It is smaller interior to energy wave into second destructive power.Chemical reaction velocity is very fast during due to explosive charge, and height is formed in moment
Warm high pressure gas, and with high power (every kilogram of explosive detonation moment output power is up to 5 × 10 kilowatts) to extraneous work done,
Surrounding medium is made to be deformed by strong impact, compression or fragmentation.The process of explosive reaction necessarily leads to a large amount of gases, explosive
Explosion time generates hundreds of to thousands of times that gas volume is explosion front volume, is consumingly compressed in the moment of explosion a large amount of gases
Within intimate original volume, thus the high pressure of hundreds thousand of a atmospheric pressure is generated, along with the exothermicity of reaction, high temperature and pressure
For gas rapidly to surrounding medium expansion working, this has resulted in power possessed by explosive.
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 of explosive is loaded with energy-gathering jetting effect, available 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 used to build dam, dredging river, level land；In railway, highway construction, explosive is used to split
Mountain is opened a way, and digs tunnel, chamber etc.；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.
Priming system is equipped with the miniaturized component or device of explosive, can (such as heat, machinery, electricity and light by certain initial punching
Punching can) effect is incendivity or explosion, to generate expected function, common priming system have Nonel detonator, fuse cord, lead it is quick-fried
Rope, igniter cap, fire in a stove before fuel is added etc..Wherein, Nonel detonator is the abbreviation of plastic detonating tube detonator, it is to rush energy by the shock wave of detonator
Quick-fried detonator is led in the industry of excitation, is assemblied by detonator and blasting cap, for the blasting engineering of explosion danger.Nonel detonator
Include wink hair Nonel detonator and delay detonating detonator again.It sends out Nonel detonator in wink and refers to the detonator having an effect in moment
Thunder, delay detonating detonator refer to the Nonel detonator for playing time-lag action.Delay detonating detonator by action time be divided into millisecond,
Half second, second delay Nonel detonator etc..Nonel detonator has antistatic, anti lightning, anti-radio frequency, water resistant, anti-stray current
Ability, it is safe and reliable, it is simple and practicable.
In civil explosive industry now, half second delay series of delay detonating detonator is mainly using silicon systems or black powder
Formula, such Delay Tube is with regard to long, and again because being pipe male extension mode, so production and use are very inconvenient；Together
When, precision of the formula of silicon systems or black powder in the time of delaying has had reached bottleneck now, time deviation can ±
25ms/mm or so, for best situation also only in ± 20ms/mm, this is for some high-accuracy explosions or inadequate,
Therefore, it is necessary to be directed to the accuracy of delay detonating detonator to be improved.
