On April 16, 2022, the return capsule of China's Shenzhou 13 manned spacecraft successfully landed, and the manned mission was a complete success.
The high-performance thermal insulation material used in the return cabin: phenolic hollow microspheres, developed by SDSQ Advanced Materials Technology Corporation. Since the Shenzhou 8 spacecraft, the phenolic hollow microspheres developed by SDSQ have continued to "escort" China's Shenzhou series of spacecraft.
Phenolic hollow microsphere is a new material with a special hollow structure, the core is air or other gas, and the outer layer is phenolic resin. It has the characteristics of small particle size and low density…
The friction between the return cabin and the atmosphere will generate a lot of heat, which can reach a high temperature of thousands of degrees. After the phenolic hollow microspheres are applied to the outer layer of the return cabin, the temperature in the return cabin can be kept within a safe range, so that the components of the return cabin can work normally. , astronaut safety escort. The product has been successfully applied to the Shenzhou series spacecraft return capsule and the Long March 5B carrier rocket, helping my country's aerospace industry.
As a leading enterprise in synthetic resin materials in China, SDSQ owns a national invisible champion demonstration enterprise in the field of phenolic resin. For many years, SDSQ has been committed to the research and development of high-end phenolic materials. The R&D and application of phenolic resins and phenolic composite materials for field use are at the leading level in the industry. At present, the overall production capacity of SDSQ phenolic resins has reached 600,000 tons/year, ranking first in the world.
