引火元件质量对雷管延期精度影响的研究

On How the Weight of Igniter Element Affects the Delay Precision of Detonator

电引火头药量和允许误差是延期雷管设计中的一个重要问题;通过实验,在引火药同一配方、延期体相同切长及相同的装配的条件下分别研究电引火头质量的大小对硅系、硼系和钨系延期元件延期精度的影响;结果表明:随着电引火头质量的增大,硅系、硼系和钨系的延期时间出现了相同的递变规律,而硅系和硼系延期精度的变化与钨系变化不同。

The weight and allowable deviation of fusehead is an important part in the design of delay detonator.On the condition of homology formula,identical length of delay tube and the same fitting the paper researches the weight of fusehead on effect of delay precision of delay element of silicon type,boron type and tungsten type.The results indicate that,with the increasing weight of fusehead,the delay time of silicon type,boron type appears the same alternation rule,but the delay precision of silicon type and boron type differs to the tungsten type.
