Definitions
- the invention is concerned with the production or release of the active as camouflage mist alkali metal or alkaline earth metal chloride aerosols by the implementation of plastic-bound pyrotechnic active compounds in particular in smoke particles.
- Pyrotechnic mixtures for the production of inorganic aerosols for military camouflage purposes often contain toxicologically harmful substances.
- the pyrotechnic active materials can be relatively easily replaced by finely ground inorganic substance / mineral mixtures in the above-mentioned quick-fog casting bodies, which are then applied via the Zerlegerladung.
- the masses of the respective applications can be well simulated in the given volume via the bulk density of the powdered substance / mineral mixtures and / or their compaction in the specified volume in the area of the quick-mist hand-throwing bodies.
- the burnup characteristic of pyrotechnic fogging compositions which generate the inorganic substances which act as fog in conjunction with atmospheric moisture only by reacting them in the form of condensation aerosols, can be achieved by applications involving pyrotechnic heating beds for sublimation of organic (color smoke) or inorganic (eg alkali metal chlorides) Use substances, only to be simulated conditionally.
- the invention is based on the idea of using a plastic-bound pyrotechnic mixture analogously to the known condensation aerosol mist-producing pyrotechnic active compounds, with which relatively less toxic, camouflage-active alkali metal or alkaline earth metal chloride aerosols are generated "in situ" by reaction
- the corresponding perchlorates as alkali metal or alkaline earth metal chloride source in the implementation of the proposed pyrotechnic mixtures of the contained chlorinated rubber in conjunction with the alkali metal or Erdalkalimetall- carbonates or phosphates contained additionally generates the corresponding alkali metal or alkaline earth metal chloride mixed in such a ratio to one another that a neutral mist in the range of pH 5 - 7 (based on aerosol) is formed.
- a misting set having the above features of the invention includes, for example
- the mist effect of the active compositions can be increased by the addition of ammonium perchlorate with the correspondingly required amounts of alkali metal or alkaline earth metal carbonates or phosphates.
- This effect is due to the additional release of water vapor which favors the mist condensation. This can u on customer requirements u. a. be reacted with respect to fog performance, toxicity and pH neutrality of the aerosol in a simple manner.
- a fog set in continuation of the invention includes, for example
- the heat of reaction liberated in the implementation of the pyrotechnic active material is used for the sublimation of the alkali metal or alkaline earth metal chlorides which act as aerosol.
- the plastic-bound pyrotechnic mixture according to the invention therefore has at least one oxidizing agent, a carbonate and / or phosphate or a mixture of carbonates and / or phosphates from the group of alkali or alkaline earth metals, a chlorinated rubber and a plasticizer. This may optionally be added to a further binder and / or graphite.
- the oxidizing agent should preferably be a perchlorate or a mixture of perchlorates from the group of alkali metals or alkaline earth metals. Additionally or alternatively, ammonium perchlorate can be included as an oxidizing agent.
- the plasticizer is preferably an organic substance or a substance mixture from the group of adipates, citrates or phthalates.
- the plasticizer may be an organic phosphoric acid ester or a phosphoric acid ester mixture.
- an organic titanate or an organic titanate mixture is preferably used as an additional binder.
- plastic-bound pyrotechnic active material which is suitable for use purposes by varying the composition for the production of camouflage nebulas to vermedoxischen camouflage.
- the plastic-bonded pyrotechnic Active mass like other nebulising masses, can also be used in projectiles / ammunition, hand-held objects or stationary applications.
- the proposed plastic-bonded active material is particularly suitable for use as a shell-less body, so that, among other things compared to z. B. Farbrauchap dutiesen more powerful hand-throwing bodies with masses up to 300 g are available.
- Envelopeless hand-throwing bodies on the basis of the proposed plastic-bound pyrotechnic mixtures are similar in geometry, mass, erosion characteristics and time to nearly 4 of the corresponding, likewise plastic-bound, NT nebulizing agent application whose mist-active component is zinc chloride or complexed zinc chloride (NT nebula, see http: // www.brandstoff-passin.de/download/Merkblatt NT Nebel Archives. This allows a realistic training with reduced toxicity potential, ie the proposed plastic-bound active materials allow in connection with the NT-Nebelwirkmasse the provision of a handling etc. complete deployment and training system for fog hand throwing body.
