Definitions

  • the present invention relates to pyrotechnic mist sets which produce impenetrable mists in the visible and infrared range.
  • EU-A 0 037 515 it is also known to combine mist from halogen donors / metal powders or phosphor mist with a further secondary mist from organic acids or microballoons in order to produce larger agglomerates which also have a light absorption in the range of> 8 ⁇ m .
  • the alkali salts sodium, potassium, lithium nitrate used as oxidizing agents in these mixtures cause, among other things. also a signal effect (coloring of the flame), but are not suitable for changing the infrared absorption.
  • cesium salts in the near infrared range up to 12 ⁇ m have no absorptions that can be attributed to vibration in which the cesium ions are involved (cesium halides have none, cesium nitrate only shows the vibration of the nitrate group at 7.2 ⁇ m ), direct absorption of the IR light cannot be considered for the effect. Because the amounts used are based on the total amount Mist rate only correspond to an average of 25%, and correspondingly the other mist-forming components are present in smaller quantities, the increase in the number of particles in the dispersed system cannot be held responsible for the effect.
  • the present invention has also set itself the task of increasing the fog yield of phosphorus-containing fog sets.
  • the effectiveness can be further increased by adding ammonium chloride.
  • the primer has the following components: magnesium powder (1.2 kg) iron blue (0.9 kg), boron amorphous (2.39 kg), powdered chlorinated paraffin (0.8 kg) and black powder (4.71 kg).
  • the magnesium powder and iron blue were premixed; the chlorinated paraffin, dissolved in 2 liters of perchlorethylene, was added and mixed.
  • the amorphous boron was added and the mixing process repeated for 5 minutes.
  • the black powder was added as the last component, mixed with the other components for 10 minutes, dried and pressed at 1500 bar.
  • the same mixture as above is additionally mixed with 0.4 kg of cesium nitrate and processed in the same way to form pressed bodies with a weight of approx. 50 g.
  • 20 compacts are put together with a primer in a casing to form a charge.
  • 3 white plates heated to approx. 40 ° C are set up in the terrain at a distance of 10 m and from a distance of 100 m with infrared and optical viewing devices at wavelengths of 10 Ilm, 3.5 pm and 0.6 ⁇ m observed.
  • Fog charges of the above composition are fired with a propellant charge approx. 40-50 m in front of the target, where within 3 seconds a 3-15 m high and 25-40 m wide and deep fog wall forms.
  • the coverage ratios listed in the following table are determined.
  • a very good coverage of 95-100% is understood, ie the goal can no longer be distinguished from the background.
  • a good coverage of 80-95% is understood, ie the goal is almost impossible to identify.
  • Moderate is a coverage of 50-80%. Bad means coverage below 50%, where the goal can still be clearly identified.
  • the fog effect is determined according to Example 1, the results of Table 2 below being obtained.
  • the mists formed have a pH of approx. 5-7.
  • the elastomer consisted of butadiene. Polybutadiene can also be used.
  • the fog effect is determined according to Example 1, the results of Table 3 below being obtained.
  • 0.65 kg of hexachloroethane, 0.2 kg of silicon powder and 0.15 kg of aluminum powder are mixed and pressed into a casing under low pressure, which is connected to a propellant and ignition charge.
  • Butadiene (polybutadiene) is used as the binder.
