Description

Technical Field

[0001] The invention relates to the technical field of radiation effect simulation, and in particular to a composite loading sample table for simulating a temperature, humidity, atmosphere and radiation coexistence environment. Background Art

[0002] In aerospace equipment, nuclear power plants and nuclear-powered marine vessels, the degradation of electronic components is usually caused by multiple factors including radiation, temperature, atmosphere and humidity, and this type of degradation is more severe than that caused by a single factor.

[0003] Therefore, to study the aging of electronic devices and materials, it is necessary to load multiple factors such as temperature, atmosphere, and humidity simultaneously in the radiation source, so that the research on the composite radiation effect can be truly composite. However, the traditional composite radiation environment simulation test usually places the device to be tested in the atmosphere environment, humidity environment, and then in the radiation source, and then the temperature box can be directly placed in the radiation source to achieve. This traditional method cannot combine multiple factors at the same time, and the volume of the oven may be large, making it impossible to place the sample to be tested in the correct position.

[0004] The existing technology has the following disadvantages:

[0005] (1) It is impossible to load multiple complex factors at the same time and it is impossible to achieve true compounding.

[0056] In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Figure 1 The present invention is described in detail in conjunction with the embodiments.

[0057] Components and materials in a composite environment are not only affected by ionizing radiation, but also by other environmental factors, such as atmosphere, temperature and humidity. Therefore, composite loading is an important basis for passive units to realize composite environmental effect evaluation and use composite environment to control the properties of components and materials, and has a broad demand base.

[0058] In the simulation test of the composite environment, the traditional methods include:

[0059] Atmosphere factors: Place the sample to be tested in the gas and then put it into the radiation source;

[0060] Humidity factor: Place the sample to be tested in a humidity environment and then irradiate it.

[0061] Temperature factor: The sample to be tested is placed in an oven, and then the entire oven is placed into the radiation source. However, the large size of the oven is not conducive to placement, which in turn affects the dose rate adjustment.

[0062] In order to solve the shortcomings in the above problems, this embodiment provides a composite loading sample platform that simulates the coexistence environment of temperature, humidity, atmosphere, and radiation, including an atmosphere tank, a temperature control component, a salt spray component, a sensor component, a shielding lead box, and a control component.

[0063] The atmosphere tank is a sealed steel tank with pressure resistance and explosion-proof properties. The sample to be tested is placed inside the atmosphere tank, and then the atmosphere tank is placed in a radiation place;

The temperature in the atmosphere tank can be changed by the temperature control component, and the airtightness of the atmosphere tank is utilized. Based on Raoult's law, the concentration of the salt solution in the salt spray pool is regulated by changing the temperature to achieve the humidity atmosphere of the closed cavity.

[0066] Raoult's law is one of the fundamental laws of physical chemistry and can be stated as follows: "At a given temperature, the vapor pressure of the solvent in a dilute solution is equal to the vapor pressure of the pure solvent multiplied by the mole fraction of the solvent in the solution."
