Abstract
The invention provides a kind of explosion-guiding-tube type detonator without detonating powdew, especially the initiating equipment used of engineering explosion.The present invention is a kind of nonpriming material detonator, and its used alms giver's medicine is not for containing the pyrotechnic composition of priming explosive, and transitional medicine is Tai An or hexogen or octogen or their modification explosive.The characteristics of this nonpriming material detonator are the waste water that does not only have pharmacy, and performance is good, and cost is low, production, transportation, safe in utilization.All satisfy the standard of industrial detonator through its detonation rate of validation trial, power, moistureproofness, stability.
Description
The present invention relates to the initiating equipment that a kind of engineering explosion is used, particularly a kind of explosion-guiding-tube type nonpriming material detonator.
The priming explosive that Engineering detonator is adorned that adopts primacord to ignite in the engineering explosion mostly is DDNP greatly, and priming explosive is ignited by primacord during use, and priming explosive causes the detonation of detonator secondary explosive again.But to produce a large amount of poisonous and reluctant waste water when producing the DDNP priming, because the mechanical sensitivity of various primings is higher, make the security of detonator aspect manufacturing, transportation and use relatively poor simultaneously.
An important channel that addresses the above problem is responsive priming in the cancellation detonator." published the article of " plastic detonating tube formula nonpriming material detonator " on explosive 》 Za Chi the 3rd phase of nineteen eighty-two, this article proposes filling " 662 " explosive (molecular formula C in detonator in China

7) replace priming, in order to address the above problem.But higher because of this capsular cost, the stability of used " 662 " explosive is relatively poor, causes this design to fail so far to apply in engineering explosion.
The objective of the invention is to provide a kind of new explosion-guiding-tube type nonpriming material detonator, it does not only have the waste water of pharmacy, and performance is good, and cost is low, is suitable for using in the engineering explosion.
The present invention is achieved in that detonating tube primer with non-initiating agent comprises detonator, hoop, plastic bayonet plug, housing, the inner tube with flash hole, alms giver's medicine, transitional medicine, secondary explosive close up, it is characterized in that alms giver's medicine is to mix by two kinds or three kinds in three kinds of components of explosive of combustible, oxidant and non-primary explosive, or add a kind of in adhesive and the deterrent or two kinds and mix, the composition of transitional medicine is peace (molecular formula C too

8) or their modification explosive.Component and proportioning by choose reasonable alms giver medicine, this medicament both easily was detonated, simultaneously again to the mechanism insensitiveness, is equipped with again the inner tube of suitable length and proper wall thickness, make alms giver's medicine and transitional medicine in inner tube, realize COMBUSTION TO DETONATION TRANSITION, thus the secondary explosive in the detonating primer.When igniting with low explosion velocity detonator, though the inert substance in alms giver's medicine such as still really detonation of binder content increase in the detonator, thus guaranteed the reliability that detonator uses.Alms giver's medicine and transitional medicine explosion velocity rapid development, thereby interior length of tube and powder charge dose, outer cover intensity all can be reduced, thus reduced the cost of detonator.
The present invention compared with prior art is characterized in that the security of alms giver's medicine and transitional medicine is good, and promptly friction sensitivity is low, has improved the security of detonator at aspects such as production, transportation, uses; And be easy to again be detonated.All satisfy the industrial detonator standard through this detonator detonation rate of validation trial, power, moisture resistance, stability, thereby be adapted at using in the engineering explosion, to replace existing Engineering detonator.The present invention and the contrast of prior art capsular are seen attached list.
Product structure of the present invention is seen accompanying drawing.
Accompanying drawing is the longitudinal sectional drawing of a kind of concrete structure of the present invention.
The nonpriming material detonator of explosion-guiding-tube type shown in the accompanying drawing is made up of primacord (1), plastics bayonet socket plug (2), close up hoop (3), housing (4), the interior pipe (5) that has flash hole (12), alms giver's medicine (6), transitional medicine (7), secondary explosive (8) and damp-proof membranes (9,10).

7) or when the slaine of explosive or propellant powder, can obtain certain Detonation Initiation Effect.
2. when the length of inner tube (5) is 8-16mm, both satisfy the requirement that detonation forms, reduced again the cost of raw material and processing.
3. when the material of selecting housing is papery or plastics, can satisfy instructions for use, reduce again the cost of raw material.
Flash hole (12) in interior pipe (5) scribble up and down or (with) when being lined with the film that the thick plastics of one deck 0.01～0.02mm or combustiblesubstance form, neither influence is detonated performance, can improve the capsular humidity resistance again.
