Is it right to use chemical knowledge to develop the shell material of Shenzhou 14 spacecraft?

The launch of Shenzhou XIV was also equipped with more than ten kinds of coatings and components, such as inorganic thermal control coatings with long life and low ratio, high-temperature insulation materials and components, anti-ablation pollution coatings for return cabin portholes, thermal protection materials for attitude control engines, high-radiation thermal control coatings for cabin channel lighting and instruments, porthole glass and optical coatings, stray light elimination coatings, stainless steel gray chemical conversion thermal control coatings, return cabin thermal protection antenna windows, etc., which put the spacecraft in all directions. The organic temperature control coating and gyro oil for navigation developed by Shanghai Institute of Organic Chemistry also helped the successful launch of Shenzhou XIV. The 23 rd Institute of China Electric Power Branch has provided a variety of products for this mission, such as high-temperature wires, high-speed data cables, spiral cables, low-noise cables and high-temperature cables at 8℃, which has provided a strong guarantee for the complete success of the space station construction mission.

there is an engine installed in shenzhou 14 propulsion cabin, which provides power, communication and energy guarantee for the spacecraft. Harbin FRP Research Institute Co., Ltd. undertook the development of the main load-bearing structure in the propulsion cabin, including two products: load-bearing truncated cone and gas cylinder mounting bracket, which provided support and interface for the fuel carried into space by Shenzhou XIV. These two products are made of high-performance carbon fiber composite materials. Although the weight of the truncated cone is only over 3 kilograms, it can bear several tons of weight.

the window assembly is the window for astronauts to observe the outside world when they are in outer space, which can be said to be the "eyes" of astronauts. In this manned space mission, there are two sets of window products developed by Zhengzhou University, one is the in-cabin service window worn by astronauts during the launch, and the other is the new generation of space window used by astronauts in space operations.

It is reported that during the mission of Shenzhou XIV, the Tiangong Space Station with the basic configuration of Tianhe core module, Inquisition experimental module and Mengtian experimental module will be completely completed, and the national space laboratory will be built.

among them, the candlestick experimental module is mainly for space life science research, and is equipped with experimental cabinets for life ecology, biotechnology and variable gravity science, which can support the research on the response mechanism of growth, development, heredity and aging of many kinds of plants, animals and microorganisms under space conditions, as well as the experimental research on closed ecosystems, and support molecules, cells, tissues and tissues through various online detection means such as visible light, fluorescence and microscopic imaging.

Mengtian experimental cabin is mainly oriented to microgravity science research, and is equipped with experimental cabinets in the fields of fluid physics, material science, combustion science, basic physics and aerospace technology experiments, which support the research on the essential laws of substances such as multiphase flow and phase change heat transfer, basic combustion process and material solidification mechanism under the cover of gravity, and frontier experimental research such as ultra-cold atomic physics. At the same time, on the basis of Tiangong-2 space cold atomic clock, the world's first set of space cold atomic clock group consisting of hydrogen clock, rubidium clock clock and light clock will be established to form a time-frequency system with the highest frequency stability and accuracy in space, and frontier scientific research such as gravitational redshift and fine structure constant measurement will be carried out.
