The nitrocellulose emission explosive that is arranged in emission cartridge bag or cartridge is easy to light and preferably reaches neutral oxygen balance according to amount than determining ammonium nitrate explosive like this, making.This is favourable on energy and is avoided owing to oxygen excess ail gun being produced possible corrosion.Because ammonium nitrate explosive and nitrocellulose emission explosive are isolated, the igniting of nitrocellulase powder can not be subjected to the interference of ammonium nitrate explosive uncertain distribution in nitrocellulose emission explosive.By ammonium nitrate explosive and nitrocellulose emission explosive is separated, also can realize being full of definitely emission cartridge bag or cartridge man-hour adding.Ammonium nitrate is owing to the Volume Changes that phase-state change causes recedes into the background fully in addition because since ammonium nitrate emission explosive and nitrocellulose to launch explosive arranged apart and do not relate to the nitrocellulose crude granule.In addition, replace the arranged apart of ammonium nitrate emission explosive and nitrocellulose emission explosive, also ammonium nitrate is packed on watertight ground fully.The very easily wettability of ammonium nitrate is receded into the background.Therefore provide a kind of emission cartridge bag for use, it be environmental protection and have a high emission effciency.
In another favourable expansion structure of the present invention, two chambers ground, front and back on body is axial are provided with.Preferably at first be arranged on the bottom section of emission cartridge bag at this ignition charge, nitrocellulose emission explosive is arranged in the face of in the chamber of ignition charge and ammonium nitrate explosive is arranged in the chamber that deviates from ignition charge of forefront.Make ignition charge, nitrocellulose emission explosive and ammonium nitrate constitute an igniting chain by this measure.Is extraordinary according to the present invention for the ignition condition of ammonium nitrate, because can provide the pressure of the ignition energy of about 200J, about 2500 ℃ temperature, about 1000Bar and high flow velocity for using.After for example lighting a fire in ail gun, the mixture by the nitrocellulose emission explosive and the ammonium nitrate explosive of burning are formed mixes during burning in the turbulence chamber of ail gun constantly.This lasting mixing is very favorable for good combustion.In addition advantageously, combustion volume almost keeps constant during combustion process.This burning under constant volume and high loading density condition is very favorable for the sound response of whole explosives.
In a favourable expansion structure of the present invention, two chambers are inner by a partition member separately at body.This measure is the very favorable simple processing that also can realize according to emission cartridge bag of the present invention on manufacturing process.
In another expansion structure of the present invention, partition member disc shaped ground constitutes and is made of the nitrocellulose cardboard.This has advantage, that is, the nitrocellulose cardboard can burn and can not produce the problem of the partition member residue that may exist thus.
In another advantageous embodiments, the emission cartridge bag is made of medicine bubble or bubble formula cartridge, that is, body is made of vacuolar membrane.This can realize processing economically and having the advantage that the vacuolar membrane of explosive is easy to blow in combustion process.
In addition, be favourable if partition member alms bowl shape ground constitutes and made by thin-film material, for example vacuolar membrane.This partition member is particularly useful for steeping the formula cartridge, because body and partition member can for example be welded to each other in its end or be bonding mutually, and therefore makes two chambers produce outstanding sealing each other.
Other advantage of the present invention and measure are provided by dependent claims, following description and accompanying drawing.
Description of drawings
With two embodiment forms the present invention is shown in the accompanying drawings.Wherein:
Fig. 1 illustrates the longitudinal sectional drawing according to first embodiment of emission cartridge bag of the present invention;
Fig. 2 illustrates the longitudinal sectional drawing according to second embodiment of emission cartridge bag of the present invention.
The specific embodiment
Constitute cartridge and comprise a body 10 at the emission cartridge bag shown in Fig. 1, its inner room is divided into two chambers 11,12.The explosive that is arranged in the emission cartridge bag is launched explosive 13, is formed as the ammonium nitrate explosive 14 of nitrocellulase powder and chamber 12 by the nitrocellulose of chamber 11, their ground, front and back on axial direction 20 is provided with, the bottom 17 of its middle chamber 11 next-door neighbour's emission cartridge bags.On emission cartridge bag bottom 17, body 10 thickly seals by cover envelope 18 preferable medium sealing/liquid.Body 10 and cover envelope 18 are made of plastics in the present embodiment.But they also can be made by metal or other suitable material.Certainly the granularity of ammonium nitrate can be from unusual particulate to relative coarse grain.
