China Aerogels Material Technology Has Reached the World Advanced Level
In the field of new insulation materials, "aerogels" have become the hot words of ever-increasing frequency in recent two years. Research institutes continue to make new developments in research and development and make new progress in application. So, as the aerogels materials industry, the first echelon members, the development of China's aerogels materials industry, how? What is the status of commercialization? What is the direction of technology development?
China aerogels materials is in the top tier in the world
The 2014 World Congress proposed that aerogels materials, consisting of more than 90% air and less than 10% solids, can withstand pressures equivalent to thousands of times its own mass and will melt at temperatures up to 1200 ° C. In addition, its thermal conductivity and refractive index is very low, the insulation capacity of the best fiberglass is also stronger than 39 times. Because of these characteristics, aerogels materials has become an irreplaceable material in space exploration. Both Russia's space station and the Mars Pathfinder probe insulate it.
In addition to aerospace applications, aerogels are also widely used in military, petrochemical, power, metallurgy, construction, clothing and other fields, a revolutionary alternative to traditional insulation materials.
Made of aerogels materials material cold jacket, only 3mm thick, but with 40mm duck coat with the same insulation effect. In the liquid-nitrogen test at -196 ° C, the temperature inside the jacket is still about 31.6 ° C. Aerogels materials is a magical nanomaterial that can change the world. The reason why aerogels have this nature is mainly due to their special nano-porous structure.
China's industrial level of aerogels materials is almost synchronized with the world, and showed a good catch-up situation. It is understood that the establishment of ASPEN, which is closely related to NASA in 2001, is the beginning of the industrialization of aerogels materials; and the research on China aerogels materials has started from the 90s of last century. The first commercialized company was established in 2004 . At present, the aerogels materials industry leads the United States and China. China has reached the international advanced level.
On November 3, 2016, the "Long March 5" carrier launch vehicle for the new generation of China Grand Canal successfully made its first flight in Hainan's Wenchang Satellite Launch Center. Among them, the rocket gas pipeline system to provide thermal insulation is self-developed high performance nano aerogels materials insulation blankets. Aerogels materials applications in China in addition to aerospace, but also used in petrochemical, high-speed rail, oil fields and other fields, the application of a wide range of markets.
