Abstract

The invention discloses a constant-capacity combustion pressure testing device for a micro-nano energetic material, the constant-capacity combustion pressure testing device is used for testing the combustion performance of a small-quantity micro-nano energetic material, the constant-capacity combustion pressure testing device includes a micro-closed bomb vessel, a nut igniter, the micro-nano energetic material and a piezoelectric sensor, the nut igniter is fixedly connected with a micro-closed bomb vessel combustor, the micro-nano energetic material is loaded into the micro-closed bomb vesselcombustor, and the other end of the micro-closed bomb vessel is connected with the piezoelectric sensor. The constant-capacity combustion pressure testing device has the advantages of simple structure, strict sealing and convenient operation, and can meet the testing requirements of millimeter-scale micro-nano energetic materials.

Description

technical field [0001] The invention belongs to the field of performance testing of energetic materials, in particular to a constant-volume combustion pressure testing device for micro-nano energetic materials. Background technique [0002] Micro-nano energetic materials are the products of the application of micro-nano technology in the field of energetic materials in recent years. Due to their particularity in size and structure, micro-nano energetic materials have excellent physical and chemical properties that ordinary energetic materials do not have. Compared with traditional large-particle energetic materials, micro-nano energetic materials have been significantly improved in terms of sensitivity and reaction rate, and have broad application prospects in national defense and other fields. [0003] Due to the micronization of energetic material particles, the number of atoms and molecules on the particle surface increases, and the surface energy increases accordingly, m...
