Definitions

  • the present invention relates to igniters, processes for their preparation and their use.
  • the object of the present invention was to provide ignition means which do not have the disadvantages of the ignition means known in the prior art.
  • Suitable igniters are water-soluble salts of nitrotetrazole, azotetrazole and nitraminotetrazole, for example cesium nitrotetrazolate, cesium azotetrazolate and potassium nitraminotetrazolate.
  • Suitable binders according to the invention are dispersed or water-soluble binders, for example ethene-vinyl acetate copolymers (for example adhesin) or water-soluble binders, for example gum arabic, polyvinyl alcohols, cellulose derivatives or the like.
  • Organically soluble explosive polymers such as polynitrophenylene, nitropolyether or poly -1- (2,4,6-trinitrophenyl) -5-5'-ditetrazole with or without addition of a binder can also be used according to the invention.
  • Additives from soluble dyes, fluorescent indicators or X-ray tracers, for example sodium tungstate, can be used as additives for revising the igniter.
  • the mixtures according to the invention are very generally suitable for use as igniters. They are particularly suitable as igniters for igniters, for example based on metal layer elements and glow wire, and with the addition of conductive soluble substances such as colloidal silver or colloidal graphite, also for splitters.
  • the mixtures according to the invention can be applied in the form of an ignition layer, for example to metal layer element, glow wire or split igniters.
