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 VIâ€.
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 VIâ€, 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 VIâ€, but also to the National Chemical Technology Conference.
A diesel engine is an internal combustion engine similar to a thermobulb engine.Crude oil engines can be powered by a variety of oils, such as engine waste and vegetable oils.You can even use peanut oil and butter for fuel if necessary.Like thermal bulb engines, crude oil engines are primarily used as stationary engines or in boats/ships.They can run for long periods of time; for example, at the Milan World's Fair in 1906, a FRAM engine was started and ran until the end of the exhibition more than a month later.A crude engine is a low revving engine that is sized for continuous operation and can last a long time if properly maintained.
Large industrial diesel engines are capable of running on unrefined crude oil and are widely used in the oil and gas industry.In addition, many large diesel engines, such as the medium and low speed engines used on large ships, can also run on crude oil, although the crude oil requires extensive filtering and treatment before being pumped into the engine.
