FIELD: mining industry; other industries; production of the high-temperature electric detonators.
SUBSTANCE: the invention is pertaining to production of the high-temperature electric detonators. It presents the high-temperature electric detonator consisting of the tube, containing the cap charged with the blasting explosive and the electric spark igniter fixed in the tube by the method of compaction of its mouth. The electric igniter contains the igniting composition containing potassium perchlorate, potassium picrate, polyphenylsilane resin and polybutylmethacrylate resin. The invention has the purpose to ensure the reliable operation of the electrical detonator at the temperatures of 200-210°С.
EFFECT: the invention ensures the reliable operation of the electrical detonator at the temperatures of 200-210°С.
