Definitions
- the invention relates to a method for producing explosives according to the preamble of patent claim 1.
- explosive includes explosive and / or explosive, in particular solid, liquid and gelatinous substances and
- Explosives, and in particular propellant powder, are required for numerous applications, such as in blasting technology or for driving projectiles.
- the explosive or the propellant charge is present in a certain form, for example as powder or granules, as a cube or in compact form of different sizes, but is based on the explosiveness of the explosive raw material, for example based on nitrocellulose and / or nitroglycerin , poses a particular problem with regard to the processing of the same.
- US 4,963,296 and the corresponding EP 0 288 505 B1 and DE 36 35 296 A1 disclose a process for producing propellant charge powder in a solvent-free process in which a water-moist powder raw material is kneaded at an elevated temperature in a shear roller.
- the raw powder mass is fed continuously, continuously removed as a gelatinized mass at the front end of the shear roller and immediately afterwards continuously granulated.
- the resulting granulate is then fed continuously to an extruder, by means of which it is pressed into powder strands, which are processed into the finished powder by cutting or another final treatment.
- this process represents a considerable improvement of the first-mentioned POL process, whereby the processing of the granules in an extruder could not previously be guaranteed in a safe manner, since high mass pressures are generated in the press when the granules are pressed, which is considerable safety-related concerns and problems.
- the granulate was mixed with original water-moist raw material and only then rolled out into a fur on a roller and processed further. Rolling into a roll and pressing into a desired geometry is carried out using the conventional method already described above.
- the winding produced has inhomogeneities which are based on differently good or less good gelatinization of the raw materials which have been mixed with one another and have already been dewatered and gelatinized or water-moist. These have a qualitatively negative impact, so that a large part of the propellant powder is still produced by the first-mentioned conventional rolling method.
- the object of the invention is to develop a method according to EP 0 288 505 B1 such that dewatered and gelatinized granules are simple and inexpensive, while avoiding the above, in particular safety-related problems can be processed into an explosive based on nitric acid esters, and in particular into a solvent-free propellant powder.
- the object is achieved by a method according to claim 1.
- the object is achieved by a method in which a desensitized, in particular water-moist, explosive raw material is processed into a granulate by dewatering, gelatinizing and processing the explosive raw material, the granulate being formed into a block immediately after granulation by means of an isostatic press, which is then subsequently formed immediately processed in a conventional manner without problems or stored in a heat container for further processing.
- a desensitized, in particular water-moist, explosive raw material is processed into a granulate by dewatering, gelatinizing and processing the explosive raw material, the granulate being formed into a block immediately after granulation by means of an isostatic press, which is then subsequently formed immediately processed in a conventional manner without problems or stored in a heat container for further processing.
- An essential point of the invention is that the granulate is fed to the isostatic press while it is still warm and plastic.
- warm granules according to the invention takes advantage of the fact that it is easily plastically deformable and tends to flow even without or with a slight application of pressure, so that a pressing process can be carried out in a very gentle manner.
- an isostatic press is used to generate the pressing pressure, since it presses on a liquid or a plastic one
- the isostatic press is heated so that a defined temperature and thus plasticity of the
- Explosive can be adjusted. In this way it is avoided that the material to be pressed cools down and / or hardens prematurely, for example by contact with the wall of the press.
- the isostatic pressing can be carried out using a wet or dry die technique, the dry die technique being preferred due to shorter cycle times and the possibility of processing smaller quantities. Due to the shorter cycle time, the dry die technology is also well suited for high throughput and large quantities.
- the multiaxial pressure effect during dry pressing results in a high and almost completely uniform compression behavior, which leads to a very uniform density of the block produced. The productivity and economy of this isostatic pressing process can therefore be assessed as good to very good.
- the temperature control of the pressure vessel can be carried out by means of a thermostat, for example heating elements, but preferably by means of a temperature-controlled water or oil bath or the like known temperature control devices.
- the isostatic press is preferably heated so that the isostatic pressing is carried out at a temperature in the range from 30 ° C. to 130 ° C., preferably at a temperature in the range from 50 ° C. to 110 ° C. and particularly preferably in the range of 70 ° C to 95 ° C is carried out.
- the method according to the invention has the advantage that the generation of heat within the pressed material is practically avoided for block formation due to the extensive avoidance of mutual friction of the granules against one another.
- the confluent plastic is preferably heated so that the isostatic pressing is carried out at a temperature in the range from 30 ° C. to 130 ° C., preferably at a temperature in the range from 50 ° C. to 110 ° C. and particularly preferably in the range of 70 ° C to 95 ° C is carried out.
- Pressed material has a smaller surface area than a granulate, which results in lower heat losses and an associated easier temperature control of the pressed material.
- the above also applies to the explosive block produced.
- one Reaction surface is drastically reduced, which reduces the risk of unwanted burning.
- the isostatic pressing is carried out under a pressure which is reduced in comparison with atmospheric pressure, in particular a vacuum.
- vacuum here encompasses the range from a water jet vacuum to a vapor pressure corresponding to the vapor pressure of the substances used.
- the vacuum actually applied depends on the explosive mixture used, the remaining water content in the same and the desired quality level of the block. For example, by applying negative pressure, it is possible to draw off any remaining water from the mixture to be pressed and to minimize the risk of air influences in the block.
- a pressing pressure in the range from 10 ⁇ 10 6 Pa to 50 ⁇ 10 6 Pa, preferably in the range from 25 ⁇ 10 6 Pa to 35 ⁇ 10 6 Pa and particularly preferably in the range of 28, is applied in the isostatic press x 10 6 Pa to 32 x 10 6 Pa applied.
- the pressure or mass pressure and the resulting density of the compact can be varied within very wide limits, so that, for example, a relatively high water content in the granules means that a higher pressure or a thermodynamically sensitive explosive mixture, a lower pressure can be used.
- the method according to the invention is therefore versatile for processing a wide variety of explosives and explosive mixtures.
- the process according to the invention generally relates to the production of single- and double-base powders, as well as to three-base powders with the premise of one
- nitroguanidine powder and powders of diglycol dinitrate, triglycol dinitrate, methriol dinitrate and butanetriol trinitrate derived from liquid nitric acid esters are also included in the invention.
- the dewatering, gelatinizing and granulating of the explosive raw material is carried out by means of a shear roller and a granulating device immediately following it at a temperature in the range from 30 ° C to 130 ° C, preferably at a temperature in the range from 50 ° C to 110 ° C and particularly preferred performed in the range of 70 ° C to 95 ° C.
- the resultant advantage is that the granulate already has a suitable temperature for further processing in the isostatic press when it leaves the granulating device. This means that neither cooling nor additional heating of the warm granulate is necessary for further processing. In addition, maintaining a relatively constant temperature ensures gentle processing of the explosive.
- the block can be further processed in a conventional manner, for example by means of a hydraulic press.
- the block produced according to the invention can thus be transferred into a strand and cut or processed in any other way to form a finished propellant charge substrate or powder.
- an explosive raw material is initially provided, which is optionally prepared by admixing auxiliaries and additives.
- This explosive raw material is then first dewatered and gelatinized and granulated using a shear roller and a granulating device. This is preferably done at a temperature in the
- the warm plastic granulate is fed to an isostatic dry pressing device, which is tempered to 90 ° C and using a pressure of 25 x 10 6 Pa and a water jet pump vacuum to one Block pressed.
- the block is further processed in a conventional manner by means of a hydraulic press, the block becoming one
- the explosive strand is stretched and then cut.
