Definitions

  • the present invention relates to a device for generating artificial fog in a predetermined target area, wherein a plurality of briquetted smoke sets are stored in a container and can be simultaneously ignited and distributed by means of a centrifugal charge, and wherein the fog sets comprise at least one metal oxide and at least one oxygen carrier and / or have a halogen carrier, and a method for producing these fog sets.
  • red phosphorus with an oxygen carrier (DE-OS 2048 583) or metal / metal oxides with halogen carriers (DE-OS 3 037 053) serve as fog sentences.
  • this is achieved in that the individual fog sets are encased on all sides by a hydrophobic ignition layer.
  • the hydrophobic ignition layer mentioned in the claim is insensitive to moisture, i.e. mist sets covered with it resist the moisture that is present in practical use, for example in rainy weather, on wet grass, etc. - This insensitivity to moisture increases the safety of burning the smoke sets enormously.
  • a reaction mixture consisting of ammonium chloride and zinc oxide in a total amount of 70 to 90 kg is mixed and then dried in a first process step in a first process step, and ammonium perchlorate, polyvinyl chloride and zinc oxide are added to this reaction mixture in a second process step, the total amount being 8 up to 12 kg and this is mixed in a tumble mixer, and in a third process step binder in the form of nitrocellulose and acetone is added in a mechanical mixer at low speed, in a fourth process step the still moist mix is pre-dried on a flat surface, then granulated and finally dried in vacuo for 1.5 to 2.5 hours at 50 ° C. to 65 ° C. and briquetted in molds in a fifth and final process step.
  • the moisture-resistant ignition layer has a double function; it ensures a quick, safe peripheral ignition of the individual fog sets by the spin charge and is also a protective layer for the hygroscopic mixtures of the fog sets.
  • the spherical design according to claim 2 increases the surface of the ignition layer and thus additionally improves the ignition safety and is very cheap on the outside.
  • An advantageous mixture for the fog sets is described in claim 3; it has no toxic substances, so that both the mist generated from it and any combustion residue are non-toxic.
  • the following substances are suitable as organic binders: acrylic resin, halogenated hydrocarbons, condensed polyamides, synthetic rubbers, vinyl ether polymers.
  • the nitrocellulose mentioned in claim 4 influences the firing behavior of the device and regulates its burning time.
  • Collodion wool according to claim 5, has proven to be very advantageous.
  • a further improvement is made by shooting cotton, cf. Claim 6 achieved.
  • organic binders listed in claims 8 and 9 are preferably higher hydrocarbons, natural proteins, polyglycols, polysaccharides.
  • the ignition layers according to claims 10, 11, 13 and 14 have the advantage of being non-toxic.
  • An ignition layer according to claim 12 has proven useful, but is slightly toxic in the non-ignited state due to the lead coatings.
  • the method of claim 16 is very economical and reliable.
  • the mass of an ignition layer produced according to claim 17 is also easy to handle and process.
  • the ignition layer, claim 18, according to claim 19, can be applied in a simple manner to the mist sets in the desired thickness.
  • the device is expediently designed directly as an ammunition body, cf. Claim 20.
  • Fig. 1 is a fog sentence. This mist set 1 is completely enclosed with an ignition layer 2.
  • Fog set 1 consists of a mixture of 12.5% by weight ammonium chloride, 31.7% by weight zinc oxide, 36.1% by weight ammonium perchlorate, 17.7% by weight polyvinyl chloride and 2.0% by weight. -% organic binders.
  • the organic binders are 5% by weight paraffin and 95% by weight nitrocellulose in the form of collodion wool.
  • This mist set 1 is encased with an ignition layer 2, consisting of a mixture of 15 to 35% by weight boron, 5 to 25% by weight silicon powder, 50 to 70% by weight manganese dioxide and 1 up to 5% by weight of organic binders which are added during coating.
  • the silicon powder was used in a grain size of approx. 25 ⁇ m.
  • This arrangement has the great advantage of being insensitive to moisture. It is very easy to ignite, is reliable and quick with regard to the formation of a dense, ground-covering mist, and guarantees total combustion of the sets.
  • An ammunition 5, Fig. 2 includes a plurality of fog sets 1 and 1 ', which are encased by a previously described ignition layer 2. The spaces make it easier to ignite the individual pill-shaped or spherical mist sets 1, 1 '.
  • the ammunition 5 consists essentially of a tubular housing 6, in which a base plate 7 with a jacket 8 are inserted.
  • a detonator flange 9 there is a known glow starter 10 with an initiator charge 11, both of which can act on a centrifugal charge 4. - This arrangement is ignited by a current source, not shown, applied to the ignition lines 12.
  • the igniter flange 9 is non-positively fixed by a base ring 13.
  • a cover plate 14 is inserted, which closes the jacket 8 airtight with a sealing film 15 and a flange 16.
  • the fog sets 1 have a diameter of 13 mm and a height of 8 mm; the radius of the spherical cap is 9.5 mm.
  • Ammunition bodies of this type are used on vehicles, primarily on tanks, and allow these to be used to atomize their area of application within wide limits.
  • flying distances of 70 m plus and minus 20 m are easily mastered in practice.
  • the launch angle is approximately 45 °; the spreading range 40 to 50 m in diameter; the fog duration per shot 30 seconds to 60 seconds
  • the different sizes of the fog sets have different burning times and different aerodynamic resistances, so that with their suitable size and shape selection a target area can be fogged within wide limits.
  • ammunition bodies can also be created, or those that are suitable for use as throwing bodies, bombs, etc.
  • mist sets are processed in large quantities by dry premixing in a mechanical mixer and mixed wet using liquid binders such as nitrocellulose and acetone, then pre-dried, granulated and finally dried in vacuo so that they can be pressed into molds.
  • liquid binders such as nitrocellulose and acetone
  • the preferably spherical mist sets with diameters of 10 to 15 mm and total heights of up to 15 mm are provided with the viscous mixture of the ignition layer by means of a plate granulator and granulated until the ratio of ignition layer to mist set is approx. 1:10.
  • the device according to the invention and the method can be adapted to the respective needs in any variation; Large sets of mists produced by the same steps are conceivable, as well as those for small-caliber ammunition bodies (from caliber 4.5 cm).
