Definitions
- This invention relates to an igniting substance for electric and non-electric detonators for industrial purposes, where a primary explosive with explosion delay time from 0 to 9000 ms after ignition is used.
- the igniting substance will be compacted in a casing of a delay-action device, fuse or sleeve, for detonators ignited by an electric fuse head by an impulse generated by an exploder, as well as for detonators ignited by a non-electric detonation tube by means of a shock wave or a spark generated by an exploder.
- This invention also relates to two independent methods of the igniting substance manufacture.
- this invention relates to electric detonators in series or series-parallel connection.
- non-electric detonator with a firing circuit consisting of connected detonation tubes of non-electric detonators, particularly for surface destruction of rocks, mining in quarries, underground mining of rocks and tunnel excavation.
- the detonators according to the invention are to be used together with the igniting substance.
- Explosives are a group of chemical compounds that are ignited easily and start burning or explode quickly by means of external mechanical impulses (friction, impact, spearing) or by virtue of fire, heat, light, an electric spark or sound (generally by means of a uniform initial impulse).
- the output is then a shock wave or flame, depending on the explosive properties and design of the ignition device.
- the type of the output impulse is always selected according to the actual ignition system. In case of detonators, for instance, the desirable type of the output is a shock wave, while in case of caps, igniter and fuse head it is flame.
- the explosives using an igniting substance in detonators must meet a number of stringent requirements so that the substance can be used to the given purpose. These requirements include, in particular, high ignition strength, i.e. the explosive should explode at the lowest weight by means of a uniform initial impulse and in the given design.
- the detonation of the explosive generates a shock wave that must have sufficient intensity to initiate the other members of the ignition chain, in case of detonators, it is less sensitive secondary filling of penthrite C 5 H 8 N 4 O 12 , hexogene C 3 H 6 N 6 O 6 or hexanitrostilbene (HNS).
- HNS hexanitrostilbene
- lead(II) azide Pb(N 3 ) 2 is used as the explosive for detonators. This explosive has high ignition strength and proven technology of its production. Lead(II) azide, however, contains lead in its molecule, which is released by detonation in metallic form as vapour. Lead is a heavy metal, which deposits in human body with highly toxic effects on human organism. Therefore, the research in the field of explosives is today focussed on compounds that have no toxic effects on humans and are environmentally acceptable.
- a natural substitute of lead(II) azide is silver azoimide AgN 3 .
- Silver azoimide is characterised by high ignition strength surpassing that of lead(II) azide.
- Silver azoimide can be prepared using the same process equipment in a manner similar to that of lead(II) azide - by simple precipitation of silver azoimide in reaction of aqueous solutions of sodium azoimide and silver nitrate.
- silver azoimide produced in this way has an unsuitable, highly sensitive and very fine form preventing its industrial use. Therefore, in the 1950s, a new method of its production based on slow crystallisation of ammoniac solution was developed.
- the process equipment differs from the process equipment used for the production of lead(II) azide ( Taylor G. W. C.: The manufacture of silver azide RD 1336; 2/R/50 accession No. ADA 474242; ERDE, Waltham Abbey; 1950 ; GB 781 440 from 1957 ; GB 887 141 from 1962 ).
- Patent US 7 375 221 from 2008 describes the preparation of alkali salts of 4,6-diazide- N -nitro-1,3,5-triazine-2-amine.
- Rubidium and caesium salts of 4,6-diazido- N- nitro-1,3,5-triazine-2-amine were tested as potential substitutes of lead explosives ( Hirlinger J. M., Bichay M.: New primary explosives development for medium caliber stab detonators, report SERDP PP-1364, US Army ARDEC, 2004 ). Nevertheless, both salts showed low brisance in the plate dent test (0.5 mm pro for caesium salt and 0.8 mm for rubidium salt, vs. 37.3 for lead(II) azide).
- Millar Millar R. W.: Lead-free initiator materials for small electro-explosive devices for medium caliber munitions, report PP-1306, QinetiQ/FST/CR032702/1.1; 2003 ) tested silver azoimide, silver salt of 5-nitro-1 H -tetrazole, potassium salt of dinitroacetonitrile and copper(II) salt of ethylendinitramine. The first two compounds were assessed as prospective for further research, while the other two were excluded for their low brisance.
- Cyanuric triazide a compound which has been known for more than one hundred years, has also been tested recently as a substitute of lead(II) azide ( Mehta N., Cheng G., Cordaro E., Naik N., Lateer B., Hu C., Stec D., Yang K.: Performance testing of lead-free stab detonator, proceeding of NDIA fuze conference, 2006 ).
- Cyanuric triazide is characterised by high ignition strength. What is more, it could be produced using the same process equipment as that for lead(II) azide. The substance has low physical stability though. The melting temperature is only 94°C and the substance sublimes at mere 30°C ( Danilov J. N., Ilyusin M.
- Tselinsky I. V. Promyshlennye vzryvchatye veshchestva; Part I. Iniciiruyushchie vzryvshchatye veshchestva, Sankt-Peterburgskii gosudarstvennyi tekhnologicheskii institut, Sankt-Peterburg 2001 ).
- the present invention aims at providing a substitute for lead(II) azide currently used as an igniting substance in detonators which is environmentally objectionable. Another aim is to develop a simple production method for the new substance. The invention also aims at developing an electric detonator and a non-electric detonator that would be suitable for use with the new igniting substance according to this invention.
- Fig. 1 shows a skeletal formula of the metallic salt of 4,6-diazido-N-nitro-1,3,5 -triazine-2-amine, where M is a metal selected from a group comprising silver and copper:
- Fig. 2 is a schematic representation of the production reaction for the preparation of silver salt of 4,6-diazido-N-nitro-1,3,5 -triazine-2-amine from 4,6-diazido-N-nitro-1,3,5 -triazine-2-amine.
- Fig. 3 is a schematic representation of the production reaction for the preparation of silver salt of 4,6-diazido-N-nitro-1,3,5 -triazine-2-amine from sodium salt of 4,6-diazido-N-nitro-1,3,5 -triazine-2-amine.
- Fig. 4 shows an industrial electric delay-action detonator while
- Fig. 5 shows an industrial non-electric delay-action detonator
- the subject of the first independent invention is an igniting substance to be used mainly in industrial detonators. It is based on the principle that the igniting substance is made of a metallic salt of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine selected from a group of salts containing silver salt, copper(I) salt and copper(II) salt, with the following skeletal formula where M is a metal selected from a group comprising silver and copper:
- the igniting substance may be a combination of silver salt and/or copper(I) salt and/or copper(II) salt and it may be complemented with other substances.
- the major advantage of the igniting substance according to this invention is that it substitutes lead(II) azide currently produced and used as an igniting substance in detonators. It reduces the environmental load of the use of explosives as no lead is released into the natural environment.
- the detonation products contain no toxic heavy metals.
- the detonation of the aforementioned salts of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine generates silver and copper in their elemental states which, contrary to lead, are not toxic.
- Substance Lead content in detonation products (mg) Silver salt of 4,6-diazido- N -nitro-1,3,5-triazine-2-amine 0 Copper(I) salt of 4,6-diazido- N -nitro-1,3,5-triazine-2-amine 0 Copper(II) salt of 4,6-diazido- N -nitro-1,3,5-triazine-2-amine 0 Lead(II) azide 42.7
- the essence of the second independent invention which is the production method of silver salt of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine, lies in that the heated aqueous solution of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine is mixed with the aqueous solution of silver nitrate AgNO 3 and, while stirring vigorously, the silver salt of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine is precipitated and then filtered off and dried at laboratory temperature
- the solution of 0.5 g of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine in 20 ml of water (2.24 mmol) is heated at the temperature of 45°C ⁇ 3°C, then the solution of 0.44 g of silver nitrate AgNO 3 in 20 ml of water (2.59 mmol) is added and the produced precipitate of silver salt of 4,6-diazido-N-nitro-1,3,5 -triazine-2-amine is left in the solution for 35-55 minutes while stirring it vigorously and then filtered off and let dry.
- the essence of another independent invention which relates to the production method of the silver salt of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine, lies in that the heated aqueous solution of the sodium salt of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine is mixed with the aqueous solution of silver nitrate AgNO 3 and, while stirring vigorously, the silver salt of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine is precipitated and then filtered off and dried at laboratory temperature
- An independent invention is also a non-electric industrial detonator which is designed only for use with the igniting substances according to the invention. It has a casing in the form of a cup with an inserted detonation tube and a space for secondary explosive at the bottom of the cup closed with a lid. The space is closed at the top with a time-delay device with a cylindrical case containing delay-action composition and with the primary explosive below it, above the space for the secondary explosive.
- the primary explosive as the igniting substance is made of a metallic salt of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine selected from a group of salts containing silver salt, copper(I) salt and copper(II) salt, with the following skeletal formula where M is a metal selected from a group comprising silver and copper:
- Another independent invention is an electric industrial detonator which has a casing in the form of a cup with an inserted electric fuse head and supply cables.
- the casing is space for at least the secondary explosive and a time-delay device with a cylindrical case containing delay-action composition and with the primary explosive below it, above the space for the secondary explosive.
- the primary explosive as the igniting substance is made of a metallic salt of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine selected from a group of salts containing silver salt, copper(I) salt and copper(II) salt, with the following skeletal formula where M is a metal selected from a group comprising silver and copper:
- An advantage of both inventions relating to industrial detonators is that they use a modified design of the existing detonators and no new equipment for their manufacture has to be developed.
- the igniting substance silver salt of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine was used as the primary explosive in the electric instantaneous detonator.
- the igniting substance was filled in the fuse in the amount of 0.045 to 0.060 g together with penthrite C 5 H 8 N 4 O 12 in the amount of 0.030 to 0.35 g. Both substances were compressed with the force of 56 to 69 MPa.
- the secondary explosive of the instantaneous electric detonator was penthrite C 5 H 8 N 4 O 12 in the amount of 2x 0.360 to 0.380 g compressed with the force of 64 to 70 MPa in an aluminium or copper cup.
- the secondary explosive can also be hexogen C 3 H 6 N 6 O 6 in the amount of 2x 0.380 to 0.400 g compressed with the force of 64 to 70 MPa in an aluminium or copper cup.
- the instantaneous electric detonator was fitted with an electric igniter.
- the igniting substance silver salt of 4,6-diazido-N-nitro-1,3,5-triazine-2-amine, was used as the primary explosive in the delay-action electric detonator.
- the igniting substance was filled in the case of the delay-action device in the amount of 0.045 to 0.060 g together with penthrite C 5 H 8 N 4 O 12 in the amount of 0.030 to 0.035 g.
