On the 19th, it was confirmed from Director Chen Donghong of the Military Affairs Office of the China Petroleum and Chemical Industry Association that domestic chemical materials accounted for 90% of the total mass of the "Shenzhou VI" manned spacecraft, and the localization rate of these chemical products used in "Shenzhou VI" reached 100% is entirely our own independent innovation product.
According to Chen Donghong, there are 110 companies directly involved in the "Shenzhou VI" research and development, but more than 3,000 indirectly involved companies. Coatings, adhesives, high-performance lubricants, rubber seals, propellants (rocket fuels), high-performance lubricants, and high-performance instrument oils produced by chemical companies have made tremendous contributions to the successful launch and successful return of “Shenzhou VI”.
Chen Donghong said that the success of the Shenzhou-series spacecraft not only promoted the independent innovation of China's chemical technology, but also drove China's chemical companies to create high-quality products. Among them, the dozens of solid and liquid propellant materials researched and developed by the Liming Chemical Research Institute have filled many gaps in China's aerospace industry and national defense construction. The five propellants used by the "Shenzhou VI" and dozens of tons of fuel, high-performance materials for manufacturing spacecraft, and almost all seals were developed and produced by Dawn Chemical Research Institute. These products were used in "Shenzhou VI", which undoubtedly improved the popularity of Limingyuan and the credibility of its products.
Chen Donghong also said that the J series adhesive developed by the Heilongjiang Research Institute of Petroleum Chemistry firmly bonds certain special and critical non-metal materials and components in the spacecraft to ensure that they do not come off and fly away after launch. This time, the J series adhesives have demonstrated their skill in the “Shenzhou VI”, which shows that China’s petrochemical industry and research level are moving closer to the world’s advanced level through independent innovation capabilities.
The paints used on the "Shenzhou VI" manned spacecraft and the "Changzheng II" F-type launch vehicle are all manufactured by Tianjin Lighthouse Paint Co., Ltd., and lighthouse paints are also known to the world.
Chen Donghong said that the first National Chemical Science and Technology Conference organized after the establishment of the Association will be held in Beijing on the 19th. What is worth celebrating is that the outstanding achievements China's chemical industry has made in independent innovation have not only given the best gift to “Shenzhou VI”, but also to the National Chemical Technology Conference.

Boiler Membrane Wall

Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Water wall tubes are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the boiler.
