Industrial Base: Zhongfu Shenying 10000 Ton Carbon Fiber Production Base Was Established

　　 During the Mid Autumn Festival National Day holiday, Xinhua News Agency published a report titled "Finance and Economics Deeply", which deeply introduced the development of domestic carbon fiber and its achievements in expanding into high-end industrial manufacturing and cutting-edge science and technology, boosting and inspiring the confidence in the development of China's new material industry.

　　 After oxidation, carbonization and other processes, the milky polyacrylonitrile precursor turns from white to yellow, from yellow to brown, and finally becomes a shiny black carbon fiber... Recently, the reporter walked into the 10000 ton carbon fiber production base of Zhongfu Shenying Carbon Fiber Xining Co., Ltd. to experience the surging high-quality development vitality here.

　　 zero 1、 "King of New Materials"

　　 The carbon fiber is as thin as a hair and as light as a feather. The diameter of a single fiber is only 5 to 7 microns, about one tenth of the thickness of a human hair, and the density is about one fourth of that of steel. At the same time, it is as strong as steel. A bundle of one meter long T1000 carbon fiber weighs about 0.5g, but it can bear about 500kg of tension.

　　 With superior mechanical properties, corrosion resistance, oxidation resistance, non rusting and other characteristics, carbon fiber is now added to resin, metal, ceramics, concrete and other materials, becoming an important reinforcement material for manufacturing advanced composite materials. Its application range is increasingly wide, and it has become the "king of new materials" in many people's minds.

　　 From baseball bats and tennis rackets, to bicycles, cars, wind power blades, to large aircraft, carrier rockets... In the exhibition hall of the Zhongfu Shenying Carbon Fiber Production Base in Xining, Qinghai Province, there are numerous physical objects and model exhibits, which shows that the application of this new material is expanding towards high-end industrial manufacturing and cutting-edge science and technology.

　　 As an important market of carbon fiber, China once relied heavily on imports of carbon fiber, which was very expensive. Therefore, carbon fiber is also called "black gold". At that time, the high-performance T700 carbon fiber in the market once sold at a high price of several million yuan per ton. Later, when the domestic high-performance carbon fiber "bloomed and bore fruit", the price of carbon fiber in the international market fell back.

　 　 zero 2、 Break through the dilemma of industrialization

　　 The development and preparation of thin and lightweight carbon fiber is quite complicated.

　　 When entering the workshop, the automated production line is running at full power. Workers are busy at their posts. Bundles of filaments extend in an orderly manner to the distance. After low-temperature carbonization, high-temperature carbonization, drying and other processes, they are wound into a shaft of high-performance black carbon fibers.

　　 Carbon fiber equipment technology is a systematic project integrating materials science, chemistry, textile science, mechanical automation and other disciplines. "The whole production process of the base includes more than 100 processes, involving more than 300 key technologies and more than 3000 process parameters. Each parameter change may cause a chain reaction and affect product performance," said Lian Feng, general manager of Zhongfu Shenying Xining Company.

　　 In fact, although scientific researchers have done a lot of work and accumulated a large number of scientific research achievements, due to the strict patent protection and comprehensive technical blockade of carbon fiber in foreign countries, Chinese enterprises have gone through an extremely difficult road of carbon fiber industrialization.

　　 It is reported that over the years, Zhongfu Shenying has always followed the most advanced carbon fiber manufacturing technology in the world, targeted the T700 and T800 products most needed by the market, continued to increase research and development investment, and constantly carried out key core technology research.

　　 Fortunately, we have achieved success - Zhongfu Shenying has successfully achieved breakthroughs in key core technologies of carbon fiber dry jet wet spinning and the localization of core equipment, systematically mastered the large-scale production technology of high-performance carbon fiber, and achieved the coverage of multi category carbon fiber products. At the same time, it took only 700 days to build a 10000 ton carbon fiber production base on a wasteland on the plateau.

　　 zero 3、 Let more new materials "fly into ordinary people's homes"

　　 In the eyes of industry insiders, China's carbon fiber industry still has shortcomings such as backward basic research, and still lags behind international industry giants in cost control and quality stability.

　　 "Our goal is to build a world-class carbon fiber enterprise with global competitiveness." The head of Zhongfu Shenying said that the enterprise will demand itself with higher standards, strengthen scientific research and development, improve business efficiency, achieve sustainable development, and constantly improve the international competitiveness of domestic carbon fiber.
