The problem of thermal safety research of 1 kilogram of explosive under semi restriction condition at present is solved, and whole-process visualized observation and recording of testing phenomena and real-time qualitative analysis of cooking-off process gas products are achieved. The visualized explosive cooking-off and gas product analysis device mainly consists of three parts including a high-definition image pickup system, an explosive cooking-off system and a gas analysis system. The device adjusts and records the cooking-off temperature of a tested explosive by adopting a program control method. The reaction phenomena in the explosive testing process are recorded through the high-definition image pickup system. The qualitative analysis is conducted on decomposed gas products at different stages in the cooking-off process through the gas analysis system. The visualized explosive cooking-off and gas product analysis device is mainly used for thermal safety research of an energy-containing material / formula.

Description

technical field [0001] The invention relates to a visual explosive cook-off and gas product analysis device, which is mainly used for thermal safety research of 1 kg level of explosive under semi-constrained conditions. Background technique [0002] The thermal safety of explosives is an important aspect of explosive safety research. For the development of new formulations, understanding thermal safety indicators such as reaction phenomena, reaction grades, lag periods, and critical explosion temperatures of explosives under different heating conditions is of great importance for determining the corresponding process parameters and understanding the safety boundary when the process is scaled up. Guiding significance. Furthermore, combined with specific model items, the thermal safety of explosive formulations also has an important practical effect on safe and reliable use issues such as its popularization and application, daily maintenance, and storage management.

AI Technical Summary

Problems solved by technology

Due to the small amount of sample used by DSC, TG, etc., it is difficult to include all components when sampling under the condition of ensuring the particle shape of the components

The resulting decomposition curve is distorted in comparison with the decomposition history of the mixed sample, which may form a wrong judgment

The sample size of the thermal explosion tank test is on the order of 50g, which is still small compared with the actual situation, and the reaction phenomenon during the test cannot be observed

The fast and slow cook-off test is on the order of kilograms, but the test is constrained by a closed steel shell, which is obviously different from the actual process, and the subtle phenomena of the reaction cannot be observed

[0004] Furthermore, none of the above research methods can obtain the reaction phenomena of the tested explosives during the test and the real-time analysis of the decomposition gas products in different reaction stages.
