A study of kinetic behaviours of the effective centralite/stabilizer consumption reaction of propellants using a multi-temperature artificial accelerated ageing test
Using a multi-temperature artificial ageing testing apparatus and a standard method of determining the effective centralite/stabilizer content, the effective centralite/stabilizer content for varying time period in propellants heated at 95 °C, 90 °C, 85 °C, 75 °C and 65 °C was measured. Bethelot...

Summary: | Using a multi-temperature artificial ageing testing apparatus and a standard method of determining the effective centralite/stabilizer content, the effective centralite/stabilizer content for varying time period in propellants heated at 95
°C, 90
°C, 85
°C, 75
°C and 65
°C was measured. Bethelot's equation and Semenov's equation in the temperature range of 65–95
°C for 81 propellants were established. The safe storage life at 30
°C, kinetic parameters [the apparent activation energy (
E) and the pre-exponential constant (
A)] and isolife temperatures obtained from the established equations and the activation energy (
E
α=0.5) obtained by integral isoconversional non-linear method for 81 propellants: single-base gun propellants (DF-01–DF-16), double-base gun propellants (SF-01–SF-13), tri-base gun propellants (SG-01–SG-02), nitramine gun propellants (GSF-01–GSF-18), double-base propellants (ST-01–ST-13), and composite modified double-base propellants (GST-01–GST-19), were given. Information was obtained on the effective centralite/stabilizer consumption reaction and the kinetic compensation effect. |
