Problems solved by technology

[0003] Traditional energetic material simulants still contain energetic material nitrocellulose (NC) (Document 1, Han Minyuan, Zhu Kaijin, Chen Yali, Development of Modified Double Base Propellant Substitute Materials, Solid Rocket Technology [J], 2011,4 (34):478-481) and highly active metal powder (aluminum powder) (document 2, Ma Ning, Chen Song, Jiang Haolong and other high-viscosity explosive simulant acoustic resonance mixing experiment research, Guangzhou Chemical Industry [J], 2015,19(43):46-49), the existence of these substances makes the energetic material simulants not completely non-energetic simulants, and there are still safety risks during the experiment

Embodiment 1

[0018] The present embodiment is implemented with reference to the following weight percentage composition:

[0019]

[0020] Preparation of this example

[0021] This embodiment is used for pouring molding of pouring equipment. Weighing - mixing - pouring. The specific operation process is:

[0022] a. Weighing

[0023] The components of the simulant were weighed according to the weight percent of Example 1, 0.8 kg of hydroxyl-terminated polybutadiene, 0.4 kg of dioctyl adipate, 2.9 kg of gypsum powder, 5.8 kg of sodium sulfate, and 0.07 kg of glass microspheres. kg, lecithin 0.03kg.

[0024] b. mix

[0025] Pour all the anhydrous sodium sulfate and gypsum powder into the kneading pot, then pour in hydroxyl-terminated polybutadiene and dioctyl adipate, close the lid of the kneading pot, turn on the stirring paddle and run for 90 minutes, then stop the machine and add lecithin Finally, run for another 30 minutes, stop the machine, discharge the material, and pour it i...

Embodiment 2

[0029] The present embodiment is implemented with reference to the following weight percentage composition:

[0030]

[0031] This example is used for continuous kneading process test. Pour gypsum powder into hopper I, anhydrous sodium sulfate into hopper II, hydroxyl-terminated polybutadiene into tank I, and dioctyl adipate into tank Body II. The solid material metering and feeding device is connected under the feeding hopper, and the material in the tank is connected to the peristaltic metering pump through the pipeline. Start the continuous kneader, adjust the process parameters to the required value, start the solid material metering and feeding device, start the peristaltic pump, start the control program, press The formula ratio of the simulants is used to set the feeding rate of each material, and when the feeding is started, each material will be continuously fed to the continuous kneader at the set rate.

Abstract

The invention discloses an energetic material simulant, and aims at solving the problems that in the installation, debugging and trial operation processes before formal production of new equipment andnew processes, equipment operation is possibly unstable, high safety risks exist when energetic materials are adopted for trial run in the unreliable parameter control state, and harm is brought to the equipment and on-site operators. The energetic material simulant is composed of an adhesive, a plasticizer, an oxide simulant, an energetic material stimulant component, a density regulator and a thickener. The simulant is high in adaptability and can simulate pouring of real materials of explosives and powders.

Description

technical field [0001] The present invention relates to an energetic material simulant, in particular to an energetic material simulant for pouring, which is mainly used for the materials used in research and development, installation and commissioning, trial production process and new process application of equipment for producing propellant and explosive products . Background technique [0002] The production process of explosives products mainly includes raw material pretreatment, mixing, kneading, molding, curing, post-treatment and other processes. The equipment involved in these processes mainly includes dryers, screening machines, mixing machines, kneading machines, pouring machines, stretching machines, extruders, ovens, shaping machines, etc. In the process of developing or building the above-mentioned equipment, material tests are required. When the equipment has not been adjusted to the normal working state, the test of energetic raw materials is directly used, a...
