Abstract
Gasproof electric detonator containing no detonating agent.The present invention relates to is a kind ofly having the Gasproof electric detonator that uses under the environment of gas, particularly Gasproof electric detonator containing no detonating agent.Be characterized in not containing in the detonator priming, main charge adopts the high explosive that adds blast reducer, and powder squib longer dimension, therefore eliminate the factors that produce flame, reduced the mechanical sensitivity of detonator, made this detonator performance safety, produce the problem of contaminated wastewater in having avoided producing, through evidence, its every index is all up to specification, can be used for coal mine underground explosion safely.
Description
The present invention is the civil engineering explosive, particularly has the no detonating capsule of anti-gas performance.
At present institute's Gasproof electric detonator of producing and using generally is made up of following part: have delay element, priming, shell, the strengthening cap of anti-gas performance and be added with the high explosive of blast reducer, delay element must have the very little performance of gunpowder flame, thereby need adopt more special processing method to it, as draw lead pipe or change the prescription etc. of delay powder, this must cause cost of anti-gas detonator to increase.In addition, the medicament that detonates that adopts in the thunder production has mercury fulminate, lead azide, lead azide and lead styphnate eutectic (DS eutectic), dinitrodiazophenol (DDNP) etc.Above-mentioned some priming can produce a large amount of poisonous waste water in manufacture process, these waste water are difficult to handle, seriously contaminated environment.And the mechanical sensitivity of various primings is all higher, all has unsafe factor to exist in production, transportation and the use.For this reason, Nanjing Science ﹠ Engineering Univ has proposed a kind of nonpriming material detonator (number of patent application: CN66200656U), this kind detonator solved detonator in producing pollution problem and safety problem in production, transportation and the use, but being changed in the detonation process by burning, it can produce a large amount of flames, therefore, be unfavorable under the environment that has gas to exist, using.
In view of the foregoing, the purpose of this invention is to provide a kind of performance safety, cost is low, and anti-gas performance is arranged, the detonator of no contaminated wastewater in the production process.
Implementation of the present invention: will be loaded on the length that powder squib in the outer pipe shell is made 14～28mm, the burning of its inside and detonation wave developmental process are had in certain-length and the interior pipe than the strong constraint condition at one carry out, no flame outwards releases.Simultaneously, main charge adopts the high explosive that adds blast reducer, and the flame that produces in the blast is eliminated, thereby reaches the purpose of anti-gas.
Below in conjunction with several embodiment of shown in the drawings electric cap, the invention will be further described.

Embodiment 1, sees Fig. 1, and powder squib 2 is placed in the multiple copper steel outer pipe shell 1, ignites pipe range 28mm, the one end opening, the delay powder 3 of packing into, ignition charge 4 and change quick-fried medicine 6, the other end has a flash hole 5.Changeing behind the quick-fried medicine is booster explosive 7 and the main charge 8 that is loaded in the outer pipe shell, and electric ignition medicine head 9 is loaded on the outer pipe shell top.Delay powder is 250 milligrams of silicon series postponing medicines, and ignition charge is potassium hyperchlorate (kClO
4), plumbous rhodanate (Pb(CNS)
2) and aluminum fluoride (AlF
3) mixture, or potassium hyperchlorate and lead ferrocyanide (Pb
2(Fe(CN)
6)) 80 milligrams in mixture, change quick-fried medicine and booster explosive and be Qin'an (PETN), each is with 300 milligrams and 200 milligrams, main charge is the hexogen (RDX) that contains 15% potassium chloride, its dose is 500 milligrams, and is added with blast reducer.Assemble 100,50 series connection lead plate perforation tests are all qualified; 50 are carried out the gas blasting test, and gas ignition rate is 0/50.
Embodiment 2; See Fig. 2, its outer pipe shell is a papery, and powder squib length is 14～20mm.Ignition charge 4 is housed in the powder squib and changes quick-fried medicine 6, all the other medicaments put in order and composition identical with embodiment 1.Ignition charge is 60 milligrams, changes 250 milligrams of quick-fried medicines, 50 milligrams of booster explosives, 500 milligrams of main charges.Because of this example does not add delay powder, thus can promote explosive accelerated combustion to change detonation, as wink hairdo detonator use.Assemble 80,20 series connection lead plate perforation tests are all qualified; The 10 quick-fried 2# rock explosives of carrying out the coffin upon burial are all ignited 50 and are carried out gas and ignite experiment, and gas ignition rate is 0/50.
Embodiment 3; See Fig. 3, outer pipe shell is a papery, ignites pipe range 25mm, wherein various medicaments are arranged with embodiment 1, delay powder is 300 milligrams of silicon series postponing medicines, and the ignition charge composition is with embodiment 1,90 milligrams of doses, changeing quick-fried medicine is 300 milligrams of Tai'an, booster explosive is 200 milligrams of Tai'an, and main charge is 500 milligrams of RDXs that contain 10% calcirm-fluoride, assembles 85,10 series connection lead plate perforating experiments are all qualified; 25 outbreak defer time determination tests, other requirement of level under satisfying; 50 are carried out gas ignition experiment, and its gas ignition rate is 0/50.
Embodiment 4; Shown in Fig. 4 structure, outer pipe shell material is a steel, the ignition charge composition is with embodiment 1,60 milligrams of doses, booster explosive and change quick-fried medicine and be all Tai'an, each 200 milligrams and 300 milligrams, main charge is the hexogen that contains 8% calcirm-fluoride, ignites pipe range 16mm, assembles 70,20 series connection lead plate perforating experiments are all qualified; 50 gas are ignited experiment, and gas ignition rate is 0/50.
