Abstract

The invention relates to a technical method for staining an ignition bridgehead of an electronic with an explosive. The method comprises the following steps: (1) explosive mixing: preparing an explosive head raw material which comprises an M explosive, a P explosive and an F explosive; (2) M explosive staining: extending a bridge wire of the ignition bridgehead into the M explosive obtained by explosive mixing to stain with the explosive and drying the bridge wire once each time, and staining with the M explosive and drying the bridge wire alternately twice; (3) P explosive staining: extendingthe bridge wire, dried in step (2), of the ignition bridgehead into the P explosive to stain with the explosive, drying the bridge wire, and staining with the P explosive and drying the bridge wire alternately for three to four times; (4) F explosive staining: extending the bridge wire dried in step (3), of the ignition bridgehead into the F explosive to stain with the F explosive, drying the bridge wire, and staining with the F explosive and drying the bridge wire alternately; (5) final drying: performing final drying on the ignition bridgehead dried in step (4). The ignition bridgehead sensitivity produced according to the method provided by the invention is moderate in sensitivity, and reliable in quality, safety in production, transportation and use is ensured, and the cost of an electronic detonator delay module is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of production of firing bridge heads of electronic detonators, in particular to a process method for dipping the firing bridge heads of electronic detonators with medicine. Background technique [0002] In recent years, due to the wide application of blasting technology, electronic detonators are widely used in the blasting process. The ignition part is also called the ignition bridge head, including the bridge wire and ignition powder. Drop-shaped ignition element. [0003] The ignition bridgehead produced by the existing ignition bridgehead dipping method is either too insensitive to increase the cost of the electronic detonator delay module and has poor ignition reliability; or it is too sensitive to cause production, transportation and use safety problems, and even cause accidents. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide an electronic deto...
