Description
Technical Field
The invention belongs to the technical field of energetic material product tests, and particularly relates to a multi-temperature-zone hot baking test device for an energetic material product.
Background
The energetic materials, including explosives, propellants, etc., are widely used in the fields of aerospace, military, etc. Various unexpected factors exist in the production, transportation and use processes of related products, such as fire accidents caused by unexpected transportation of roads and railways, fuel combustion accidents caused by the spaceflight launching process and the like, so that the energetic materials face thermal safety risks, and combustion and even explosion conditions can occur when the energetic materials are serious. Therefore, by conducting a related test, it is necessary to evaluate the safety of energetic materials in a hot baking environment.
The importance of developing the thermal safety evaluation test of the energetic materials is recognized by related units at home and abroad for a long time, and related test standards are even formed after years of development. Foreign standards include: american army standard MIL-STD-2105C, english standard MHSMP-84-22UC-45June1984. Domestic standards include: WJ2243-94 "weapon Industrial Co Standard- -explosive test method, rapid fire test", GJB5309.29-2004 "initiating explosive device test method part 29: baking explosion test, etc.
Meanwhile, in order to research the reaction mechanism of the energetic materials in the hot baking environment and the like of multiple units such as Beijing university, shaanxi applied physical chemistry institute, china engineering physical institute and the like, various test devices are independently researched and developed according to the various test standards, the pertinence is improved, the indexes and the functions are advanced, various tests are carried out by means of the test devices, and the researches on the reaction mechanism of the energetic materials in the hot baking environment and the like of different materials, the heating rate and the energetic materials in different structures are researched.
The hot bake test can be classified into a fast bake test and a slow bake test. The test with a typical heating rate of less than 0.05 ℃/s is referred to as a slow bake test. And the test with a temperature rise rate of more than 1 deg.c/s is called the quick bake test. Test equipment for achieving the rate of temperature rise index can be broadly divided into the following modes:
One device is a baking furnace with good heat exchange performance. And (3) putting the product into a test furnace with a temperature control function, and controlling the temperature rising rate of the furnace temperature so as to finish a hot baking test. The test device can generally complete slow baking tests with small size, small dosage and slow heating rate.
For large-size products, a large-size temperature box can be adopted for the slow baking test, and the principle of the slow baking test is similar to that of a baking furnace. For the quick-baking test, a special burning pool is generally built, a burning medium such as coal oil is injected into the pool, and a product and a bracket are placed in the middle of the burning pool, so that the quick-baking test under the burning state is completed.
The technical means can realize the hot baking test of the product. Through the technical means, the reaction mechanism of the energetic material in the hot baking environment, the adaptability assessment of the product in the hot environment and the like are all significantly explored, but some aspects which can be improved exist.
The equivalent degree of the hot baking environment simulation needs to be improved;
The temperature in the closed space is utilized to exchange heat with the product, so that the temperature rise response rate of the product is obtained. The existing stage of the baking furnace and the temperature box are all single temperature control environments, namely, the products are placed anyway, the postures of the products are adjusted, and the surrounding temperature field environments are the same. Such laboratory environments are necessary for the characterization of a single material, such as an explosive of a certain nature. However, when the weapon ammunition of full-size grade with different structures is subjected to fire environment and aerodynamic heat environment, the response temperature rise conditions of different parts of the product and different control surfaces at the same position are different. While the reaction of explosives is concerned with the formation of localized hot spots. For explosive products, the part which reaches the reaction temperature conditions such as explosion, deflagration and the like in the temperature distribution is the most concerned part for product examination. Therefore, a temperature field simulation technology for temperature response of different parts of an energetic material product in a hot baking environment is an important aspect to be improved in the prior art.
Accurate and comprehensive simulation, and insufficient means for providing mechanistic analysis;
The fire test can truly simulate the heated temperature field condition of the energetic material in the fire environment, is a real simulation of a thermal accident scene, and can realize an effective means of the rapid baking test of the energetic material. However: 1. the fire test device can only simulate the flame field environment, and other environments are not enough to simulate, such as the surrounding of the storage area of the energetic material product is ignited, and the slow baking effect on the energetic material is realized; 2. the fire test generally refers to a field fire test for safety, and is easily affected by weather environment in the implementation process; 3. under the fire environment, the heating range and the heating rate of the product are all characterized by a quick baking test, and the heating range and the heating rate are not easy to control and can not finish a slow baking test. Through research documents, no slow baking test aiming at high-dose energetic material products is found at the current stage at home and abroad. For the whole-grade product, the reaction environment of the energetic material is also influenced by factors such as structural characteristics of the product, use environment and the like, and the prior art means needs to improve another aspect.
The process detection technology needs to be improved;
Because of the limitations of technical means, the reaction mechanism of the whole-grade energetic material product in the hot baking environment is not fully researched at the present stage. For example, the relation between the response temperature and the material state of the energetic material in the whole process of the heat baking test is reflected on the characteristic parameters, and the change history curve of the parameters along with the temperature and the time, the explosion combustion critical interval and the like are still to be further studied.
Therefore, it is highly desirable to develop a multi-temperature zone hot bake test device for energetic material products to solve the above problems.

The present application is provided with:
1. Integrated design of multi-temperature zone fast/slow baking test equipment
According to the scheme, through integrated design, the fast and slow baking tests under different indexes can be realized. According to different heat baking test types, the multi-temperature-zone heat loading terminal 7 with different specifications and models can be selected.
