Abstract

The invention provides a thermal vacuum device with the function of absorbing condensable volatile pollutants, which includes a vacuum tank and a control device for absorbing condensable volatile pollutants. The control device for absorbing condensable volatile pollutants includes a low-temperature pollution adsorption screen and a movable support , louver shading plate, anti-radiation screen and adsorption screen temperature control system, low-temperature pollution adsorption screen and anti-radiation screen are installed on movable brackets, radiation protection screen is located on the side of the low-temperature pollution adsorption screen facing away from the product, low-temperature pollution adsorption screen is facing One side of the product is equipped with a louver baffle, the louver baffle is fixed with a movable bracket, the movable bracket is installed in the vacuum tank through the guide rail in the tank, and the low-temperature pollution adsorption screen is connected to the adsorption screen temperature control system outside the vacuum tank through the flange assembly. The invention has reasonable thermal design and wide applicability, and effectively reduces the influence of the background temperature on the temperature stability of the surface of the low-temperature adsorption screen.

Description

technical field [0001] The invention relates to the technical field of spacecraft environment simulation equipment, in particular to a thermal vacuum equipment with the function of absorbing condensable volatile pollutants and a method for using it. Background technique [0002] Any deposition of contamination on a spacecraft subsystem will alter the performance of the system to some extent. During the development, assembly, testing, storage, and transportation of spacecraft, they will be polluted by the external environment and the spacecraft itself. During thermal vacuum tests, the non-metallic sheaths, adhesives, thermal control coatings and fillers of cables used on spacecraft will outgas and lose mass due to diffusion and desorption, and some of them will be redistributed on cooler surfaces. Condensation can cause pollution to spacecraft equipment and affect product performance. [0003] Further test results show that typical condensable volatiles include phthalates a...
