Explosive substance solution critical explosion temperature testing container

Abstract

The invention belongs to the technical field of explosive safety testing, and particularly relates to a novel explosive substance solution critical explosion temperature testing container. The container is used for testing the critical explosion temperature of an explosive mixture of one or more impurities in different solvents with different concentrations. The container comprises a container barrel, a barrel cover and a barrel bottom, wherein a pressure release valve and a non-contact infrared temperature sensor are arranged on the barrel cover, a reaction tank is arranged at the bottom of the container barrel, a reaction pool is arranged in the reaction tank, an electric heating wire is disposed outside the reaction pool, a contact type temperature sensor is disposed at the bottom of the reaction tank, a pressure sensor is disposed at the bottom of the container barrel, a non-contact infrared temperature sensor is arranged on the barrel cover, a sealing cover is arranged on the upper portion of a sensor hole, and transparent tempered glass is arranged on the lower portion of the sensor hole. The container has the main advantages that the required volume of the reaction container can be designed according to the TNT equivalent of the actual reaction, the design program is clear, and calculation and processing are easy; the equivalent is convenient to adjust, the experiment cost is greatly reduced and the safety performance is high.

Description

technical field [0001] The invention belongs to the technical field of safety testing of explosives, and in particular relates to a novel critical explosion temperature test container of an explosive substance solution. Background technique [0002] At present, the research on explosive substances is mainly focused on the synthesis, refinement, production and other processes based on the thermal decomposition behavior and mechanism in solid and gas phases. In the actual production process, the synthesis and preparation of most explosive substances , Purification and other processes are all carried out in the solution, and explosive substances have different thermal safety properties in different solvents. Under the stimulation and influence of external factors, the thermal stability of the solution will change under different temperatures and pressures. The degree is not the same. [0003] Taking ammonium nitrate as an example, as a common chemical fertilizer and industrial...

Problems solved by technology

Solve the problem that the explosion limit moisture of the existing water-containing liquid mixture has a great influence on the results, and there are obvious differences between the composition of the steam and the natural volatile gas phase composition of the liquid mixture during production, storage, transportation and use during the test, and the test results are meaningless question

However, the internal volume of the device is small, the single test volume is small, and it is inconvenient to use
