摘要:
为解决当前磁电雷管生产工艺复杂、成本较高的问题，设计了一种新型磁电雷管。首先，阐述了磁电雷管的设计原理。在此基础上，分析了感应电流I2与次级绕组匝数n2、次级端脚线及桥丝电阻R2、磁导率μ、电流频率f的关系，确定了n2、R2、μ和f等的取值。生产中，采用了磁环、脚线定位注塑措施；确定了磁电雷管的磁环材料，初、次级绕组匝数和电线材质；优化了点火药配方和桥丝的直径，点火药选择m(苦味酸钾)∶m(高氯酸钾)＝47.30∶44.65的零氧配方，桥丝直径为0.03 mm,解决了规模生产的一致性问题。结果表明：本产品生产工艺简单，能够实现大批量生产，同时具有很强的可靠性，满足了行业的需求。
Abstract:
A new kind of magnetic electric detonator was designed with respect to the challenges of complex production process and high cost in current production of magnetic electric detonator. Design principle of the magnetic electric detonator was introduced at first. Based on this, relationship between inductive current I2 and number of secondary winding turns n2,inductive current I2and bridge wire resistance R2, induced current I2 and magnetic conductivity μ, inductive current I2 and current frequency f were analyzed and the value of n2, R2, μ and f were determined. Magnet ring, wire positioning and mold injection were used in the production. Magnet ring material, number of primary or secondary winding turns, and wire material were also determined. Ignition formula and diameter of bridge wire were optimized. Zero oxygen balance was chosen in the ignition, in which m(potassium picrate)∶m(potassium hyperchlorate) =47.30∶44.65. Dia meter of bridge wire was 0.03 mm. Consistency of scale production has been solved. All the results show that this produc tion process is simple and could achieve large scale production, and it has a high reliability. It could meet the needs of various industries simultaneously.
