Embodiment Construction

[0016] Attached below figure 1 The present invention will be further described in detail with specific embodiments. as the picture shows:

[0017] The production example is: Weighing and mixing: Weigh 50 grams of potassium picrate (water content less than 0.1%), 50 grams of lead, silicon and iron powder (ratio: 9:1), measure 15ml of polyvinyl alcohol aqueous solution, and pour them in turn Put it into a 300ml glass beaker, stir it evenly with a bakelite stick, then sieve it, and continue stirring for 40 minutes. After mixing evenly, let it stand for use.

[0018] Wipe the primer: spread the above-mentioned viscous agent evenly around the bridge wire of the electric ignition head. Pores, cracks, defects, and exposed bridge wires are not allowed to appear on the good ignition powder. The weight of the ignition powder Between 8 and 12mg. Drying at 35-45°C until the moisture content is less than 0.1%, the manufacture of the ignition powder of the present invention is completed....

Abstract

The invention aims to provide a manufacturing method of a potassium picrate-red lead silicon series electric ignition charge. The manufacturing method comprises the steps of: weighing, mixing, smearing the ignition charge and the like, so that the ignition charge has better flame sensitivity and lower mechanical strength; and thus, the ignition capacity of the electric ignition charge is high, and the intrinsic safety and reliability during production and use can be effectively improved.

Description

1. Technical field: [0001] The invention relates to the field of industrial explosive production, in particular to a method for manufacturing potassium picrate-lead-dan-silicon electric ignition powder. 2. Background technology: [0002] At present, the ignition method of industrial electric detonators mainly adopts electric heating. The electric ignition powder is coated with ignition powder around the metal bridge wire. Under the action of a certain intensity of detonation current (minimum ignition current ≤ 450mA), it uses the thermal effect of the current to ignite quickly and reliably through the burning of the bridge wire, and outputs a certain intensity. The flame charge is used to ignite the pyrotechnic element of the delay charge or the primer. It generally consists of four parts: foot line, sealing plug, bridge wire, and ignition powder. The pyrotechnic powder is a pyrotechnic powder that has a low ignition point, high combustion temperature, high thermal sensiti...
