摘要
A modified manometric vacuum stability test (MVST) apparatus as well as a differential thermal analyzer (DTA) and a thermogravimetric analyzer (TGA) were used to study the decomposition of nitrocellulose (NC) and pentaerythritol tetranitrate (PETN) and their mixtures. Two NC samples with different nitrogen contents (12.6% and 13.4%) were investigated. The MVST apparatus was operated isothermally at three temperatures (100, 110 and 120-degrees-C) for 40 h, and the DTA and TGA experiments were performed with a constant heating rate (10-degrees-C min-1). The activation energies of the thermal decomposition reactions were determined from both the MVST and DTA test results. It was found that the activation energies for the decomposition of the mixtures fell between those of PETN and NC. The compatibility between NC and PETN was confirmed by the experiments.
