Definitions
- the invention relates to a method according to the preamble of patent claim 1.
- DE-PS 21 31 282 is the combination of a casting and printing process for the production of explosive
- the invention has for its object to provide a method for producing explosive charges of high explosive power from non-pourable explosive mixtures.
- the charges produced according to the invention are technically at the upper limit of performance
- the cargo owes this performance to the high proportion of highly explosive HE explosives (HMX, BDX, PETN).
- HMX highly explosive HE explosives
- BDX highly explosive HE explosives
- PETN highly explosive HE explosives
- the load In order to use die casting technology, the load must contain at least 7.5% TNT, TNB or TNCB.
- the load to reduce the vulnerability must contain care-enhancing additives in order to guarantee safe processing and the load property against
- a plastic content of 0.5 to 2.5% improves the nourishing properties, since it surpasses the TNT's workability. This plastic content in particular reduces the sensitivity to shock and sensitivity to shards.
- the commercially available explosive mixture used as the starting substance, the z. B. consists of 90% HMX as a solid component and 10% TNT as a fusible component, is first in a heatable mixer to the processing temperature of about 80 ° C
- TNB or TNCB used, with the weight ratios: RDX / TNT: 85/12; 90/10; 92.5 / 7.5,
- detonation speed is selected as a measure of the performance, particularly high values for RDX / TNT: 90/10 (detonation speed: 8620 m / s) and 92.5 / 7.5 (detonation speed: 8660 m / s) ) reached.
- the explosive mixture is heated just below the melting point of the meltable component, so that the mixture remains free-flowing.
- This procedure has the advantage that the free-flowing explosive mixture can be metered very easily, so that it can be reproduced in a simple manner
- the individual HE explosive grains are first coated directly with the thermoplastic binder and only then is the fusible component (e.g. TNT) added.
- the fusible component e.g. TNT
- the layering of the HE grains with the binder can be carried out, for example, using the so-called slurry process.
- an aqueous suspension of the HE particles is prepared by vigorous stirring.
- a polymer solution is metered into this suspension.
- the polymers are coated by affinity forces for the solid particles.
- the solvent is then stripped off by dilution.
- the entire suspension (slurry) has to
- the suspension is filtered and the residue is dried in vacuo at temperatures of 40 ° C. Particles of any grain size can be coated.
- a corresponding grain is shown in Fig. 2a.
- the grain of the solid explosive component e is denoted by 5 and the shell of the thermoplastic binder (polymer) by 6.
- HMX explosive granules suspended in distilled water with stirring. This suspension was called
- Solvent content can be kept low since a sufficiently good solvation is achieved quickly. After evaporation of the solvent, the
- the HE particles were first coated with TNT in an upstream process step.
- a suspension of the HE particles in water was created.
- the TNT amount of 1 to 2% based on the explosive is dissolved in a solvent.
- the solvent should not or only slightly dissolve the solid explosive particles.
- This TNT solution is added to the suspension and the solvent removed again by heating the slurry to 80 ° C and distilling.
- the TNT covers it
- the coated material is then cooled and filtered.
- This pretreated, TNT-coated explosive material is then - as described above - further treated and provided with a binder layer.
- a corresponding layer structure of such particles is shown in Fig. 2b.
- the HE grain is denoted by 5, the TNT coating by 7 and the binder layer by 8.
- the particular advantage of the particle structure shown in Fig. 2b is that the TNT explosive component is initially liquefied by the processing temperature. Due to its ease of movement, all cracks, gaps, holes etc. on the solid HE explosive are completely filled with material. This effect is desirable because an explosive charge structure that is as compact as possible makes a decisive contribution to reducing the sensitivity to dangerous external influences.
- Made polymer solution Processing takes place by preparing the polymer solution in which the desired TNT content (1 to 2%) is introduced and dissolved. The further procedure from the start takes place according to the example in FIG. 2a.
