Description
Technical field
The present invention relates to a kind of electric initiating explosive devices to belong to electric initiating explosive device technology more particularly to a kind of no bridge electric initiating explosive device.
Background technique
Traditional electric initiating explosive device transducing is first, generally igniter wire or bridge band type structure, they are by means of very thin resistance
Silk (or resistive film), generates Joule heat after energization, the chemistry that Lai Yinfa is attached to the medicament containing energy around igniter wire (bridge band) is anti-
It answers.By taking igniter wire product as an example, from the point of view of its manufacturing process, maximum process difficult point is welding of the igniter wire in payment to a porter,
Necessary firm welding, and unfavorable harm cannot be generated to subsequent product quality.The welding method of use is conventional tin nothing but
Weldering and relatively advanced stored energy welding, ultrasonic bond or Laser Welding.There are the problem of mainly have: solder joint will appear rosin joint, igniter wire resistance
Value spreads big and igniter wire by damage inconspicuous etc., to need reinforcement technique means to detect the quality water of weldering bridge process
It is flat.If then also needing to increase the processes such as cleaning, dehydration, drying, once not washing clean clearly, just will appear using soldering
The corrosion phenomenon of solder joint, causes product quality sharply to decline, and implies the drawbacks of length stores up unstability, life of product cannot be guaranteed.
The production of bridge band is then complex, contains a series of works such as target processing, sputtering, deposition, exposure mask, etching, bonding wire, post-processing
Sequence, directly results in that yields is not high, and cost is higher.
The semiconductive bridge transducing member technology that newly-developed gets up is exactly right using the processing method of electronic device
Monocrystalline silicon doping, obtains the controllable minute yardstick film of electron density, when extraneous inputing power, will undergo temperature rise, melting, gasification
Process forms electric detonation plasma, is applied to the medicament containing energy contacted, can cause medicament burning or explosion, completes initial
Arousal function.The entire production process of semiconductive bridge include: compound pulling single crystal silicon, insulating layer, polycrystalline silicon growth, doping,
(multiple) etching, bonding, painting silver paste etc., very cumbersome and complicated, manufacturing cost certainly will increase, it is difficult to reach what generalization used
Stage.On the basis of semiconductive bridge film, the bridge film containing energy of the bridge of activity containing zirconium and compound thermite is obtained by physical method, they
Also in the technical research stage, still there is a distance from engineering application.
Conducting Composition for Type electric initiating explosive device constitutes Conducting Composition for Type by cladding of the graphite to the medicament containing energy, and previous conductive component is only limited to
Graphite composite powder, the problem of bringing be form medicine resistance value it is very big, it is high to the sensibility of electric energy, in daily production, storage and use
In it is very dangerous, because due to be eliminated.(Zhu Shunguan, Zhang Lin, Li Yan wait carbon crystal coating electric ignition the research of bridge characteristic [J] to document
2015 (2015 03): 1-4.) priming system reports a kind of electric initiating explosive device of the member using carbon crystal as transducing, firing voltage is most
Low to can reach 17.3V, igniting is reliable at 70 DEG C and -50 DEG C, and has preferable antistatic effect.
Summary of the invention
The object of the present invention is to provide a kind of no bridge electric initiating explosive device and its applications.
Realizing the object of the invention technical solution is: the no bridge electric initiating explosive device includes 3~90wt% carbon fiber powder
With 97~10wt% medicament containing energy.
Wherein, further, the carbon fiber powder be carbon fiber is made after ball milling average length be 1 μm~
2000 μm of powder.
Further, the partial size of the medicament containing energy is 200 μm or less.
The medicament containing energy uses single-compound primary explosive or priming composition.
Application of the above-mentioned no bridge electric initiating explosive device as igniting element and detonation element.
Compared with prior art, the invention has the advantages that
1) design without bridge electric initiating explosive device eliminates the welding of igniter wire or semiconductor chip, detection, greatly reduces into
This；
2) can be by the way of pressing without bridge electric initiating explosive device, it can also be different to adapt to by the way of dipping in medicine
Demand；
