Manufacturing method of nickel hydrazine nitrate-minium silicon series igniting powder

Abstract

The invention relates to a manufacturing method of nickel hydrazine nitrate-minium silicon series igniting powder, relating to a manufacturing method of igniting powder contained in an electric firing head of an industrial electric detonator. The nickel hydrazine nitrate-minium silicon series igniting powder comprises minium-silicoferrite. The nickel hydrazine nitrate-minium silicon series igniting powder is characterized in that a base stock of the igniting powder comprises the following components in the terms of the weight of 100 grams: 85-92 grams of nickel hydrazine nitrate and 8-15 grams of minium-silicoferrite, wherein the apparent specific gravity of the nickel hydrazine nitrate is 0.75-1.10 grams / cm<3>, and the water content is less than 0.1%; and the proportion of the minium to the silicoferrite of the minium-silicoferrite is 75%:25%. The manufacturing method comprises the following steps of: uniformly mixing the nickel hydrazine nitrate with the minium-silicoferrite; then taking 15 ml of a water solution with the main component of polyvinyl alcohol and the concentration of 8-10 percent to be uniformly mixed with the base stock, and stirring to generate the viscous igniting powder. The invention has the advantages of high igniting capacity, high firing reliability under the action of currents, lower mechanical sensitivity, no corrosion on a leg wire and an igniter wire of the electric firing head, higher shaping degree and rigidity and waste water recycling and is beneficial to environmental protection.

Description

Technical field: [0001] The invention relates to a method for manufacturing an ignition powder in an electric fuse head of an industrial electric detonator, in particular to a method for manufacturing an ignition powder of nickel-hydrazine nitrate-lead-dan-silicon system. Background technique: [0002] The industrial electric detonator is a glowing bridge wire type electric detonator. The electric fuse is coated with igniting powder around the metal bridge wire. Can, the pyrotechnic element used to ignite the delay charge or the primer. It generally consists of four parts: foot line, sealing plug, bridge wire, and ignition powder. The ignition powder is a pyrotechnic powder with high heat sensitivity and strong ignition ability, which acts as a fire starter. In the industrial electric detonator, the role of the ignition powder is to generate a flame that ignites the delay charge or the primer, and is sensitive to electric heat, that is, a high sensitivity to the hot wire. ...
