摘要

Reduced Sensitivity RDX (RS-RDX) for use in cast-cured and pressable PBX compositions have received a lot of attention and interest from the explosive community in the recent years. There are several producers of RS-RDX, using two different nitration processes for the RDX synthesis (the Woolwich process and the Bachmann process). In addition there are different processes for obtaining the Reduced Sensitivity properties. In one case it has been reported that RS-RDX produced by the Bachmann process will loose its insensitivity towards shock initiation during ageing. RS-RDX produced by Dyno Nobel by the Bachmann process has therefore undergone extensive accelerated ageing testing. The samples have been aged at 60°C and 70°C and the shock sensitivity tested by the Small Scale Water Gap-test (BICT Gap-test) and the Intermediate Scale Gap-test according to STANAG 4488. The results demonstrate that the Dyno Nobel RS-RDX from the Bachmann process retains the insensitivity towards shock during ageing. No degradation of the shock sensitivity has been observed. Dyno Nobel has recently published the results from the first major study of Reduced Sensitivity HMX (RS-HMX) of different particle size distributions. The shock sensitivity is at the same level as for RS-RDX in comparable compositions. Shock sensitivity results for RS-HMX used in both pressable and cast-cured compositions will be presented. Accelerated ageing testing of RS-HMX have been initiated. Such studies have never been reported in the literature. Initial results from the ageing study will be presented.
