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

Embodiment Construction

[0015] Attached below figure 1 And embodiment the present invention is described further.

[0016] 1.1 Manufacture of the present invention

[0017] The oven-burning box (16) of the present invention measures 70cm (length)×60cm×60cm, the overall heat-resistant temperature of the box is not less than 300°C, the temperature control accuracy is 0.1-10°C / min, and the heat preservation accuracy is ±1°C. HD camera (1) recording resolution ≥ 720P. The gas analyzer (12) can realize the addition and combination of gas detection sensors according to different explosives to be tested.

[0018] 1.2 Assembly of the present invention

[0019] Sample assembly: put the explosive powder to be tested into the round bottom flask (6), shake gently to make the assembled explosive particles as dense as possible, and limit the explosive sample to the inner mouth of the throat of the round bottom flask. After the sample assembly is completed, put the round-bottomed flask (6) into the reserved sma...

Abstract

The invention discloses a visualized explosive cooking-off and gas product analysis device. 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.
