Embodiment 1

[0105] Example 1: Performance evaluation of energetic material A:

[0106] This embodiment is a performance evaluation method of energetic material A, including:

[0107] Step 1: Determine the material type;

[0108] The energetic material A is a hydroxylamine salt containing a nitrofurazan structure, and the structure contains nitrogen-rich explosive groups such as a nitro group and a furoxan ring, and its type belongs to high-energy explosives;

[0109] Step 2: Determine the development stage;

[0110] Through the structural design and theoretical calculation, it is estimated that the energetic material A has a high energy density. After the design of the synthetic route, the laboratory preparation has been completed and a stable sample has been obtained. The structural characterization is consistent with the design. ; It can be seen that the energetic material A is in the stage of synthetic exploration and research;

Embodiment 2

[0129] Example 2: Performance evaluation of energetic material B:

[0130] The present embodiment provides a performance evaluation method for energetic material B, including:

[0131] Step 1: Determine the material type

[0132] Energetic material B is an ionic energetic compound with a white crystal in appearance, lower sensitivity than RDX, no chlorine element, very little smoke generated during combustion, higher heat of formation, but more sensitive to light and moisture . Energetic material B is rich in oxygen element, and the oxygen balance is 25.8%. It can be used as an oxidant in the formulation of explosives. Therefore, the type of energetic material B is an energetic oxidant.

[0133] Step 2: Determine the development stage

[0134] Energetic material B can be prepared through a variety of synthetic routes, two of which have industrial prospects. At present, key technologies such as low-temperature nitrification, separation and purification, and safe drying have...

According to the method, evaluation indexes and methods are selected for different types of energetic materials in each development stage, and the principle and process of performance evaluation are established, and the method is suitable for performance evaluation work of specific energetic materials.

Description

technical field [0001] The invention belongs to the field of performance evaluation of energetic materials, and mainly relates to a basic step and process for carrying out performance evaluation for a specific energetic material. Background technique [0002] Energetic materials are the common basis for the development and production of weapons and equipment, and are the core elements to achieve high-efficiency damage to weapons. Energetic materials, as an important component of explosive formulations such as mixed explosives, solid propellants, and propellants, are used in weapons and equipment. To have actual combat effectiveness, it needs to go through various stages such as material R&D and production, formula development, charging process development, and equipment performance verification. Among them, the R&D and production of materials is the basis for all subsequent applications, and the performance of the material itself determines whether it can be used in weapons a...
