Research on the performance parameters variations of SCB initiator with lead thiocyanate during storage

In order to find SCB initiators' performance parameters variations during storage, this paper used the accelerated life test to do performance testing. The results showed that there was no significant change in burst time and burst energy of SCB initiators. But the ignition time of SCB initiators had delayed. According to the XRD of ignition powder, decomposition of the powder results in a long time of ignition, which is mainly due to the ingredients change of lead thiocyanate.
