Method for testing performances of initiating explosive material changing with temperature

Abstract

The invention discloses a method for testing the performances of an initiating explosive material changing with temperature. According to the invention, a method of combined usage of a high-definition digital camera and a differential scanning calorimeter is employed; a cover of the differential scanning calorimeter is opened, and a small amount of an initiating explosive material sample is placed in a crucible; the differential scanning calorimeter is continuously heated or cooled from a normal temperature at a certain temperature varying rate; the high-definition digital camera is used to shoot pictures to record physical appearance of the sample, and thus, continuous testing of physical changes of the initiating explosive material with temperature is realized. With the method provided by the invention, analysis of changes of chemical performances of initiating explosive materials with temperature can be realized, and analysis of changes of physical performances of loose or compact initiating explosive materials with temperature can also be realized; the method has the characteristic of easy and safe operation, can realize more comprehensive analysis of changes of the initiating explosive material with temperature, is applicable to both analysis of changes of a variety of initiating explosive materials with temperature and analysis of changes of other reagent samples with temperature and has good versatility.

Description

technical field [0001] The invention relates to a method for testing the performance of pyrotechnic agents, in particular to a method for testing the performance of pyrotechnic agents as a function of temperature, and belongs to the technical field of pyrotechnic products. Background technique [0002] Pyrotechnic agent is a special energetic material for pyrotechnic products. Its function is to accept the weak stimulation energy given by the transducing element of pyrotechnic products, undergo a rapid chemical reaction, and release combustion, deflagration or explosion energy, so that pyrotechnic products can achieve Ignition, fire transmission, detonation, explosion transmission, delay, work and pyrotechnic effects are widely used in pyrotechnic devices such as attitude control, separation and unlocking of various rockets, missiles, spacecraft, satellites and other aircraft. Pyrotechnic agents are a class of energetic materials with extremely special properties. Compared w...
