Abstract
The invention discloses an energetic material simulator, which aims to solve the problems of unstable equipment operation and high safety risk and injury to equipment and field operators in a commissioning process of new equipment, installation and debugging before formal production of a new process and possibly in a commissioning process and in a state of unreliable parameter control by adopting an energetic material. The energetic material simulant of the invention consists of a binder, a plasticizer, an oxide simulant, an energetic material simulant, a density regulator and a thickening agent. The simulant has strong adaptability and can simulate the real materials of casting explosives and powders.
Description
Technical Field
The invention relates to an energetic material simulant, in particular to an energetic material simulant for pouring, which is mainly used as a material for equipment for producing and developing explosive products in research and development, installation and debugging, trial production processes and new process application.
Background
The production process of the explosive product mainly comprises the working procedures of raw material pretreatment, mixing, kneading, molding, curing, post-treatment and the like. The devices involved in these processes are mainly dryers, screening machines, mixing machines, kneaders, casting machines, stretching machines, extruders, ovens, shaping machines, and the like. In the process of developing or newly building the equipment, material tests are required, and the equipment is directly tested by adopting energetic raw materials under the condition that the equipment is not adjusted to a normal working state, so that the existing safety risk is higher. Therefore, the general method is to replace real materials with non-energetic simulants, so that the danger is reduced. The most important characteristic of energetic material simulants is that they are close in nature to the simulant, with closer being better.
The traditional energetic material simulant still contains energetic material Nitrocellulose (NC) (document 1, development of Korean, Zhukai jin, Chenya Li modified double-base propellant substitute, solid rocket technology [ J ],2011,4(34): 478-.
