某固体云爆剂老化前后的安全性研究

目的研究某型固体云爆剂老化后的使用安全性。方法采用真空安定性试验仪按GJB772A—97方法 501.2测试老化前后样品的安定性、相容性,采用感度设备按GJB 772A—97中的相应方法分别测试老化前后样品的撞击感度、摩擦感度以及火焰感度。结果云爆剂老化前后,每克试样在标准状态下的放气量均远远小于2 mL,安定性均合格。样品老化前后火焰感度试验均未爆,撞击感度和摩擦感度均在样品在失重1%时最高,当样品老化至失重1.5%时,爆炸概率反而比失重1%样品的降低。结论该型固体云爆剂老化前后均具有良好的安全性,老化失重达到1.5%后,仍能满足安全使用要求。

Security Study of a SE-FAE before and after Aging

Objective To study the use security of a SE-FAE after aging. Methods The stability and compatibility of the SE-FAE before and after aging were tested using vacuum stability test instrument according to method 501. 2 in GJB772A—97,at the same time,its impact sensitivity,friction sensitivity and flame sensitivity were tested by Sensitivity equipment according to the corresponding method in GJB 772A—97. Results The outgassing amount per gram samples before and after aging under standard condition were all much smaller than 2 ml,therefore their stability was all qualified. All the samples before and after aging did not explode in flame sensitivity experiment,both the impact and friction sensitivity were highest with an aging loss of 1. 0%. When the aging loss of the samples reached 1. 5%,the explosion probability was lower than the samples with an aging loss of 1. 0%. Conclusion This SE-FAE had good security both before and after aging,and it could still meet the security use requirements after the aging loss reached 1. 5%.
