摘要

The thermolysis of HMX, Estane and two of their plastic bonded explosives (PBXs) namely HXE 9505 and HXE 9010 were investigated using non-isothermal TG-DTG and DSC under an inert gas (N-2) atmosphere. Non-isothermal TG, isothermal TG and DTA were also undertaken in air atmosphere on the above-said samples. Lowering of decomposition temperature of HMX has been observed when Estane was coated over it, to make their PBXs. The extent of lowering was increased as the amount of Estane increased in the PBX. Kinetic analyses of isothermal TG data has been made by using model fitting methods as well as by using a model free isoconversional method. The merits and demerits of both modes of kinetic analysis have been critically evaluated by making use of the kinetic parameters obtained there from to explain the thermal characteristics of the samples studied. Explosion delay measurements have been made on HMX and its PBXs and the kinetic parameters were also evaluated from this data. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 40]
