Explosive explosion-proof tube device for thermal analysis experiments

Abstract

The invention relates to an explosive explosion-proof tube device for thermal analysis experiments, comprising a cylinder body (1). An end of the cylinder body (1) is provided with an opening (2), atwhich an end cap (3) is connected cooperatively. A set of lateral explosion venting holes (4) are arranged on the sidewall of the cylinder body (1); a set of bottom explosion venting holes (5) are arranged at the bottom of the cylinder body (1); and a set of end explosion venting holes (6) are arranged on the end cap (3). The invention has the following advantages: as the cylinder body of the device is in the shape of a cylinder, the cylinder body can simulate a blast hole of a blasting engineering practice, and the experimental result is closer to the engineering practice; the cylinder body is made of high-strength stainless steel to ensure rigidity of the cylinder body, and the cylinder body is rust-proof and corrosion resistant, the life is long; and with the arrangement of the lateralexplosion venting holes, the bottom explosion venting holes and the end explosion venting holes, blast wave generated by explosive blasting can be effectively released, the amount of explosive samplesfor thermal analysis experiments is increased, and safety of the experimental process is guaranteed.

Description

technical field [0001] The invention relates to the field of thermal analysis experiments of explosives, in particular to an explosion-proof cylinder device for explosives used in thermal analysis experiments. Background technique [0002] Explosive thermal analysis technology is a kind of technology to measure the dependence of explosive properties on temperature. This technology not only explores the thermal decomposition principle of explosives, but also uses thermal stability analysis methods to study the reaction kinetics of explosives under heat, so as to ensure that explosives are Safety and reliability during production and process blasting. At present, the experimental methods of thermal analysis of explosives are: differential scanning calorimetry (DSC), accelerated reaction calorimetry (ARC), photothermal analysis (DTA), microcalorimeter C 80 However, when these methods are used to study the thermal stability of explosives, the amount of explosive samples used in...
