Definitions

  • the present invention relates to pyrotechnic mist sets which produce impenetrable mists in the visible and infrared range, as characterized by the claims.
  • mist sets contain corrosive, toxic or strongly acidic components, such as phosphorus pentoxide, hydrochloric acid, sulfuric acid, titanium or zinc salts, which are extremely harmful to humans and plants in the concentration occurring in the mist.
  • phosphorus pentoxide phosphorus pentoxide
  • hydrochloric acid hydrochloric acid
  • sulfuric acid titanium or zinc salts
  • metal oxides, buffer substances and ammonium compounds it has therefore been ensured in most of today's mist sets that the mist generated only is as weakly acidic or neutral as possible. It is therefore an object of the invention to modify the known fog sentences so that they do not react as acidic as possible.
  • 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.
  • a 1.7 kg mmoniumperchlorat, 1,5 kg of zinc oxide, 0.8 kg and 0.5 kg of ammonium chloride polychloroisoprene be made into a paste with a solution of 0.5 kg of dioctyl phthalate in 1 liter of methanol.
  • the mixture is pressed through a sieve with a mesh size of 0.3-0.5 mm and dried on trays.
  • the dried granules are then pressed according to DE-AS 30 31 369 into compacts of approximately 50 g.
  • 20 pressed bodies are combined in a plastic or metal shell to form a charge using an ignition charge according to Example 2 of DE-AS 30 31 369.
  • 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 compacts with a weight of approx. 50 g.
  • 20 compacts are put together with a primer in a shell 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 ⁇ m, 3.5 ⁇ m and 0.6 ⁇ m observed. Mist loads of the above composition are propelled about 40-50 m before the target shot, where a 3-15 m high and 25-40 m wide and deep fog wall forms within seconds. At temperatures of 22 ° C and a relative humidity of 48%, the coverage ratios listed in the following ablelle T 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 coverage is 50-80%.
  • Bad means coverage below 50%, where the goal can still be clearly identified.
  • Example 2 2.5 kg of hexachloroethane, 0.8 kg of zinc oxide, 0.4 kg of silicon powder, 0.3 kg of aluminum powder and 0.3 kg of amorphous boron are mixed intensively and pasted in a kneader with 2 kg of a 10% elastomer binder solution in acetone.
  • the mixture is processed in the same process as in Example 1 into compacts which are isolated by an additional coating of methacrylic resin and combined in accordance with Example 1 to form fog loads.
  • 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.
  • 0.65 kg of red phosphorus, 0.15 kg of iron (III) oxide, 0.15 kg of aluminum powder and 0.15 kg of magnesium powder are kneaded with 0.2 kg of 10% elastomer binder and processed according to Example 1 into compacts.
  • 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.
