Definitions

  • mixtures include different solid compounds and are formulated by considering the function they must fulfill: primary or secondary explosives, oxidants, metals or reducing compounds, various additives intended either to promote mixing, or to give the composition specific properties such as than electrical conduction, thermostability or sensitivity to certain actions.
  • the manufacture of a pyrotechnic device involves the establishment, or loading, of the elements of the pyrotechnic chain and is done by introducing in the pulverulent solid state quantities perfectly dosed by volume or by mass of each pyrotechnic composition which must be previously shaping.
  • the present invention provides a pyrotechnic device of the latter type, having an easier loading process, in particular in an automatic machine for loading ammunition, and which has improved characteristics of reproducibility, aging and performance, while eliminating the aforementioned drawbacks specific to the known shaping of the various constituents of a pyrotechnic chain.
  • the invention therefore allows the production of a pyrotechnic chain by dosing successively, and in particular volumetrically, in the pulverulent state, of compositions obtained by various known shaping methods, in particular by the process for coating pyrotechnic substances described in French patent No 2309493.
  • the granulation of the delay composition can be carried out in a known manner, by introduction of the composition into a planetary mixer, of a binder and of at least one solvent, until suitable wetting of the composition and obtaining of '' a fluid and homogeneous paste. After drying, this paste is introduced into a rotary granulator actuated from a distance. The granule obtained is spread and dried, then sieved between 80 and 200 ⁇ , to obtain a granulated retarding composition suitable for industrial loading.
  • the reinforcing or uncorking composition is prepared by simple dry mixing with the rotary mixture.
  • a final compression is then carried out with a flat punch under a pressure of 1900 bar.
