The Oxidizing and Reducing Agents of existing trigger is solid, need to mix in process of production, and is made bulk, Or loaded with belt body；Trigger of the present invention enters reaction material using inflation mechanism pressurising, is loaded in advance also in its filled cavity Former agent, overcritical oxygen（Oxidant）Fill at the scene；Trigger of the present invention in production process without being pre-charged with mixing Material（Reaction material）, it is avoided that compound burns or explode in production, storage and transportation because friction, high temperature, electrostatic trigger, this The frame mode of invention avoids the potential safety hazard that transportation is brought.
Existing trigger is mainly carries out the reaction material bag packed after batch mixing using solid-state reactants, is had The sealing of effect and protection against the tide, against shock, high temperature-proof, antifriction treatment, easily occur that reaction material is made moist, reaction material and heating wire are stripped off There is gap in separation, cause to produce miso-fire；Trigger of the present invention, the overcritical oxygen in its filled cavity is uniformly inhaled It is attached in reducing agent, overcritical oxygen uniformly mixes with reducing agent, heating wire is being ignited by overcritical oxygen and the uniform attached collection of reducing agent When can realize 100% detonation, the generation of miso-fire can be prevented effectively from.
Reaction material is needed to mix under low temperature environment in existing trigger, and for solid granulates mix, its mixture homogeneity is deposited In larger limitation, after detonation, its reaction speed is slower, and the adequacy of reaction is poor, there is substantial amounts of residual, heat energy release effect Rate is below 40%；Trigger of the present invention, has the double properties of gas and liquid concurrently due to overcritical oxygen, in filled cavity Reducing agent adsorb overcritical oxygen after, can jointly be flowed with overcritical oxygen with the molecular state for dissolving, overcritical oxygen and reducing agent High uniformity mixes, and can realize fully reaction in the short time after the ignition that is powered, and heat energy release efficiency reaches more than 95%.
It is existing by the way of activator ignition, it is necessary in process of production, activator component is prepared in advance, it is typically high The strong reductant such as the strong oxidizers such as potassium chlorate and aluminium powder, it is necessary to weigh, batch mixing, stirring, type processed；Frame mode of the invention, leads to Cross and be filled with overcritical oxygen to filled cavity, make overcritical oxygen absorption on reducing agent, save conventional detonator devices（Activator）Production During required batch mixing, spice, the production technology of type processed；Meanwhile, potassium hyperchlorate, potassium permanganate are used using overcritical oxygen ratio It is lower with al powder mixt cost.
Existing trigger（Activator）, after igniting, during the course of the reaction, its reaction heat continues to be conducted to periphery, conduction To in the liquid carbon dioxide on periphery, and heat is outwards spread by surrounding liquid carbon dioxide, this kind of conduction process, carbon dioxide Temperature distributing disproportionation, heat absorption efficiency is relatively low, and carbon dioxide gasification expansion pressure is relatively low；Trigger of the present invention, its is anti- Should expect there is sealed tube body constraint, its reaction material can occur sufficient exothermic reaction under the constraint of sealed tube body, and reaction is produced High temperature and high pressure gas thing cause body moment to burst, and be instantaneously mixed into liquid carbon dioxide, high temperature and high pressure gas and two Carbonoxide moment mixes, and realizes carbon dioxide moment endothermic gasification, this kind of detonation way, relative to existing, its liquid dioxy The heat absorption speed for changing carbon is fast, and heat absorption efficiency reaches more than 98%, and the heat that its trigger is produced can sufficiently by liquid carbon dioxide Absorb, can largely lift gas blaster plasting damage effect.
Trigger of the present invention, its reaction material can fully react, and product can realize fully oxidized, its reaction product Thing is mainly nontoxic gas, pollution-free to demolition site, can effectively reduce the poisoning hidden danger of field personnel, realizes Safety blasting, it is pollution-free, produced without toxic and harmful, at once can construction operation after explosion.
After explosion, outer tube is broken gas blast device of the present invention by expansion air pressure, but in the company of connector Connect under effect, two ends termination still keeps connecting, the phenomenon that termination will not be caused to fly out, during explosion filling, blast hole Filling out husky thickness only needs the 5-15cm, top layer rock by explosion fragmentation, effectively to prevent the generation of large rock mass.
Beneficial effect：Gas blast trigger of the present invention has processes simple, low cost of manufacture, reaction material mixing The uniformity is high, exothermal efficiency is high, Transport Safety is good, without miso-fire hidden danger, liquid vapour endothermic effect is good and prevents explosion The advantage that device termination flies out.
