摘　　要：为了研究温度对数码电子雷管延期时间的影响,模拟数码电子雷管在实际使用时环境温度,同时参考国家相关标准要求,把数码电子雷管分别在-20、25、70℃温度下放置2 h后立即试验,考察温度对其延期时间的影响。试验结果表明,同一生产企业的数码电子雷管在-20℃温度下对延期时间的影响比在25、70℃更大,不同企业的引火药剂的不同配方和工艺对延期时间也有一定程度的影响。In order to study the influence of temperature on the delay time of the industrial digital electronic detonator,the ambient temperature when digital electronic detonators are actually used is simulated.At the same time,according to the relevant national standards,the digital electronic detonators are tested immediately after being placed at-20℃,25℃and 70℃for 2 hours,to investigate the influence of temperature on its delay time.The test result shows that the influence of temperature at-20℃on delay time is greater than that at 25℃or 70℃for the digital electronic detonator from the same manufacturer,and the different formulations and processes of ignition agents in different enterprises also have some influence on the delay time.
