Definitions

  • the invention relates to a pyrotechnic mixture for producing a camouflage mist.
  • Hygroscopic compounds such as metal chlorides (ZnCl2, FeCl3, AlCl3, TiCl4, SiCl4) or phosphorus oxides P2O3, P2O5) are generated and evaporated, which then hydrolyze with the air and form suitable clouds of fog.
  • ZnCl2, FeCl3, AlCl3, TiCl4, SiCl4 or phosphorus oxides P2O3, P2O5 are generated and evaporated, which then hydrolyze with the air and form suitable clouds of fog.
  • mist formed especially from so-called HC mist sets containing hexachloroethane, but also from phosphor mist sets, is extremely acidic due to hydrolysis in humid air, since hydrochloric acid (HG mist) and phosphoric acids are formed, and therefore toxic and plant-intolerant.
  • the heavy metal zinc is introduced into the environment in the most commonly used fog mixture based on hexachloroethane (HC) and zinc or zinc oxide.
  • the object of the invention is therefore to produce a camouflage mist which is particularly suitable for training purposes and which consists of a non-toxic aerosol, which therefore cannot have a toxic effect on humans and animals, and on the other hand is environmentally compatible.
  • the mist mainly consists of macronutrients suitable for plants.
  • a non-toxic mist of sufficient optical density is formed by the invention.
  • the fog is formed in the following way:
  • the components magnesium powder, potassium nitrate and potassium perchlorate already produce fog-like clouds when converted in the range of 2500 °.
  • the fog density is particularly characterized by the proportion of potassium chloride and / or sodium chloride, whose sublimation point at 1500 or boiling point at 1450 ° C are far below the reaction temperature of the reaction of magnesium and potassium nitrate.
  • the reaction products of the chemical conversion from magnesium with potassium nitrate, potassium perchlorate, calcium carbonate etc. form a useful training fog with the subliming potassium chloride or the evaporating sodium chloride without toxic or environmentally incompatible ingredients.
  • the energy (E) released in the three basic conversions mentioned is used for sublimation / evaporation of potassium chloride and sodium chloride.
  • nitrogen-releasing substances such as azodicarbonamide, oxamide or dicyandiamide are added to the mixture. This results in a continuous gas flow for better transport of the aerosol particles and a higher aerosol yield, since the permanently formed gases prevent the slag from flowing together and promote sublimation and evaporation by increasing the surface area.
  • a pure white aerosol which mainly consists of the components potassium chloride, magnesium oxide, calcium hydroxide, calcium carbonate, sodium chloride and potassium carbonate. These components are environmentally friendly and non-toxic and apart from NaCl macronutrients for plants.
  • the pH of the generated fog is highest at the point of origin (9).
  • chemical reactions of the primary oxides K2O and CaO (equations 1, 3) with components of the air, especially H2O and CO2 to form KHCO3, K2CO3, Ca (OH) 2 and CaCO3 and by dilution it quickly decreases and reaches the pH of the ambient air ( ⁇ 6) at a distance of 5-10 m from the fog source.
  • a pyrotechnic mixture with the same components as the mixture for producing the camouflage mist can be used as the ignition mixture, but in which the content of magnesium and oxidizing agent is increased to increase the sensitivity to ignition and transmission reliability.
  • the primer can e.g. consist of the following proportions: 25% Mg, 35% KNO3, 10% KClO4, 20% CaCO3, 10% KCl.
  • mist set and the primer are pressed into sleeves in a manner known per se and reacted with conventional igniters.
  • the drawing shows an embodiment of a mist body with the new mixture.
  • a sleeve 1 with bottom 3 there is the compressed mixture 4, which carries the ignition mixture 5 pressed on with it as a conclusion.
  • the embodiment of the drawing has a recess 6 for the use of an igniter known per se.
