Definitions

  • the invention relates to a method for the preparation of mercury compounds, potassium chlorate and antimony trisulfide containing primers of cartridges and similar assemblies of military products.
  • the treatment process removes the ignition effect of primers in primers and similar assemblies by converting the initial explosive contained in inert, non-ignitable compounds or substances and by converting the potassium chloride contained in the primer, which serves as an oxygen carrier, into potassium chloride.
  • the invention thus relates primarily to the field of military technology and relates to the desensitization of detonators, such as those used in primers, ignition screws, detonating devices and chemical initiators of various ammunition, locking and clearing agents, for the purpose of safely removing such military products, to ensure the safe transportation of assemblies containing such primers, as well as the safe processing of these mixtures or assemblies and products.
  • detonators such as those used in primers, ignition screws, detonating devices and chemical initiators of various ammunition, locking and clearing agents
  • CS-A 267 047 describes the recovery of mercury from mercury-fulminate waste from explosives.
  • the waste is reacted in a water suspension with Mg powder.
  • the Mg / Hg ratio is (1 to 5) to 10.
  • the Mg fulminate obtained and the excess Mg are concentrated using a Mineral acid, especially HCL, decomposes, and the mercury is separated.
  • JP-A-60 222 190 also describes the disposal of waste water containing mercury.
  • a solution containing iron ions is added to the waste water.
  • the pH is adjusted to 10 to 12 with an alkaline solution.
  • the reaction which is constantly ventilated, produces Hg ferrite.
  • the mercury ions in the water are reduced to metallic mercury by reducing agents.
  • the resulting degradation products must in any case be sent to a special waste landfill or pollute the user due to environmental damage in the form of wastewater pollution or contamination of scrap, earth, etc.
  • the aim of the invention is to find an economically justifiable and reliable process alternative for canceling the ignition effect of primers in primers and assemblies or products of a similar purpose and thus to enable their safe transport and rational processing.
  • the invention has for its object to find a simple, safe and rational method for desensitizing large quantities of primers and similar assemblies based on primers containing mercury fulminate and thus to enable the environmentally friendly disposal of this mercury-containing waste from ammunition development.
  • the primary task for the environmentally friendly disposal of the mercury-containing primers was to remove the ignition effect by chemical conversion of the explosives contained. Subsequent demercurization of the resulting mercury-containing waste is possible with the current state of the art.
  • the iron passing into the ionic form largely precipitates as Fe2O3.
  • the primers in cartridge cases are pretreated in a water bath heated to 90 ° C for 2 h. In a subsequent thermal aftertreatment, the residual water adhering to the parts is evaporated.
  • the evaporation temperature is kept at 100 ° C.
  • the prolonged exposure to water vapor at approx. 100 ° C loosens the connection between the cartridge and primer.
  • the conversion of mercury fullminate into pyrofulmin is initiated.
  • the grain boundaries of the rhombic fulminate crystals are partially destroyed and the reaction areas are enlarged.
  • the primers pretreated in this way, still pressed into the cartridge cases, are separated from the cartridge case within 3 to 12 hours and subjected to a treatment in the following manner: 8 kg of iron in the form of the anvil parts are added to a quantity of 10 kg primer (basic primer with mercury fullminate).
  • a weakly alkaline soap solution (pH 7.5 to 8.5; 1 kg of industrial soap to 400 l of water) is poured over this mixture until the liquid is about 5 cm above the solid.
  • the batch must stand until the hard-pressed primer in the primer has completely penetrated the medium and the conversion of the mercury fullminate with reaction with iron ions into an inert mercury compound or metallic mercury and the conversion of the potassium chlorate into potassium chloride has taken place.
