Abstract

The invention discloses a device and a method for measuring dissolution heat of a high-mechanical sensitiveness energetic material. The problem that dissolution heat cannot be measured or cannot be accurately measured due to a dangerous accident caused by operations such as puncture and impact when the dissolution heat of the high-mechanical sensitiveness energetic material is measured by using a conventional calorimeter is solved. According to the device, the energetic material is contained in a sample tank, a solute is dissolved in a solvent by virtue of centrifugation and infiltration actions after stirring by using a motor, the sample and the reference heat difference are transmitted to a recorder by virtue of a sensor, and the recorder records a heat change signal in a heat flow form. The method for measuring the dissolution heat of the high-mechanical sensitiveness energetic material, disclosed by the invention, comprises six steps. The device and the method disclosed by the invention can be used for measuring the dissolution heat of the energetic material by using the calorimeter, the uniform stirring can be realized, the dangerous operations such as the puncture and the impact are avoided, the risk in the test process is reduced, and the accuracy of testing data is improved.

Description

technical field [0001] The invention belongs to the field of physical and chemical testing, and mainly relates to a measuring device and method for the heat of dissolution of energetic materials with high mechanical sensitivity. Background technique [0002] The heat of solution refers to the heat generated when a certain amount of solute is dissolved in a certain amount of solvent under certain conditions. Compared with the preparation process of energetic materials, the heat of solution is an important parameter, which is related to the process safety and quality control of energetic materials in the process of synthesis and preparation. Energetic materials with high mechanical sensitivity refer to materials with high energy and high mechanical sensitivity, which are easy to decompose and cause deflagration under the action of mechanical stimuli such as impact and friction. For example Ottokin, 1,3,3,5,7,7-hexanitro-1,5-diazacyclooctane, nitroglycerin, polynitrofuran expl...
