A variety of key coatings and materials developed by Shanghai Academy of Sciences Shanghai Silicate were successfully applied to Tianzhou -4 freight ships

In this space task, the thermal control coating developed by Shanghai Siliconate solved the heat control problem of the large -area complex parts of the freight ships; the thermal protection of high -temperature feathers was successfully achieved; the smooth development of the solar wings was ensured; The bidirectional stretching polypelide film and its composite thermal control materials realize the localization of the entire process process, which is used as a sub -system for the insulating material as the sub -system of the cargo spacecraft.

As part of the structure of the cargo spacecraft, the front cabin portholes are not only a pressure -sealing function, but also provides good optical windows for astronauts. At the same time, for the harsh service conditions of the Long March VII Yaozhuo Rocket Oxygen/Meeting Oil engine turbine, the sealing ring -resistant coating developed by the sealing ring, which effectively solves the starting process of the engine special pump body. The problem of friction and wear of the secret cover.
