Abstract
The invention relates to ignition sets comprising initial explosive substances selected from the group consisting of compounds, in particular compounds of lead, which are derived from trinitropolyphenols, such as trinitrophenol, trinitroresorcinol or hydrazoic acid, for example, in mixture with oxygen-generating substances, wherein further included are initial explosive substances made of alkali metal and/or alkaline-earth metal salts of dinitrobenzofuroxanes and oxygen-generating substances made from nitrates of ammonium, guanidine, aminoguanidine, triaminoguanidine, dicyanodiamidine and from the elements of sodium, potassium, magnesium, calcium, cerium and/or from multivalent metal oxides.
Claims22
Priming charges with initial explosives selected from the group consisting of compounds derived from trinitropolyphenols or hydrazoic acid in a mix with oxygen generators, characterized in that, additionally, initial explosives comprising alkali-metal salts and/or alkaline-earth-metal salts of dinitrobenzofuroxanes are included in an amount of 5%-15% by weight based on the overall mixture,
- wherein the oxygen generators consist of at least one selected from the group consisting of lead dioxide, cerium dioxide, and nitrates of ammonium, guanidine, aminoguanidine, triaminoguanidine, dicyanodiamidine, sodium, potassium, magnesium, barium, calcium, or cerium, and
- wherein the total amount of the initial explosives is 30% to 60% by weight, based on the overall mixture, and the priming charges are ignitable at temperatures below −35° C. and down to −54° C.
A priming charge mixture comprising:
- initial explosives selected from the group consisting of compounds derived from trinitropolyphenols or hydrazoic acid;
- additional initial explosives selected from the group consisting of alkali-metal salts of dinitrobenzofuroxanes and alkaline-earth-metal salts of dinitrobenzofuroxanes, the additional initial explosives being included in an amount of 5%-15% by weight of the mixture;
- and
- oxygen generators,
- wherein the oxygen generators consist of at least one selected from the group consisting of lead dioxide, cerium dioxide, and nitrates of ammonium, guanidine, aminoguanidine, triaminoguanidine, dicyanodiamidine, sodium, potassium, magnesium, barium, calcium, or cerium, and
- wherein the total amount of the initial explosives and the additional initial explosives is 30% to 60% by weight, based on the overall mixture, and the priming charge mixture is ignitable at temperatures below −35° C. and down to −54° C.
