Název v původním jazyce

Study of Initiation Reactivity of some Plastic Explosives by Vacuum Stability Test and Non-Isothermal Differential Thermal Analysis

Popis výsledku v původním jazyce

On the basis of measurements of 18 high explosives by means of the Czech Vacuum Stability Test (VST) STABIL, a relationship has been specified between the results of this test and those of Russian manometric method. The said relationshipwas used to predict the Arrhenius parameters (Ea and log A values) of four plastic explosives based on RDX and one high explosive based on PETN (Semtex). The slopes EaR-1 of Kissinger?s equation were specified by means of non-isothermal differential thermal analysis (DTA) and evaluation of the measurement results by means of the Kissinger method. The role played by binders and plasticizers in thermal decomposition of nitramines was pointed out on the basis of relationship between the Ea values obtained from VST and theEaR-1 values obtained from DTA, both for plastic explosives, eight nitramines, Composition B and PETN. The relationships between the EaR-1 values and thermostability threshold was specified for the given group of explosives. The relations
