China Drying Network Co., Ltd. Recon Eagle Carbon Fiber Co., Ltd. held a new product conference in Shanghai and announced that through independent innovation, the company became the first and only company in China to achieve the industrialization of dry-jet wet-spinning SYT45 (equivalent to T700) carbon fiber. . This indicates that China has obtained the right of international dialogue in the field of high-performance carbon fiber production.
According to reports, this year, the Chinese Condor Eagle has fully started mass production of SYT45-grade high-performance carbon fiber. The average daily output is 12K (12,000 bundles each), about 4 tons of raw silk, 1.8 tons of carbon filament, and the product has a tensile strength of 4.5 GPa or more. , tensile modulus of 240GPa or more. Chairman Zhang Guoliang said: "In September of this year, the company will supply 50 tons of SYT45 grade carbon fiber to the market every month. By 2013, 150 tons of SYT45 grade carbon fiber will be supplied to the domestic market in large quantities every month."
As the largest domestic carbon fiber manufacturer, China Recon Eagle has developed a large number of key technologies and even world-class original technologies through independent innovation. It has achieved localization from equipment to products by 100%. According to reports, after two years of technological breakthroughs, China Recon Eagle has created a polymerization system, and after more than three years of arduous exploration and experimentation, it has achieved stable and high-speed spinning of polymerization spinning solution. At present, its spinning speed is nearly 5 times that of wet spinning, and 80 kg of large shafts are successfully wound. Its self-designed equipment was also successfully matched with its production process, which changed the traditional concept that domestic equipment could not produce high-performance carbon fiber. In addition, Zhongfu Condor has invested 15 million yuan to reform the existing 100-ton production line. After more than six months of research, it overcomes the technical difficulties of high-densification precursor fiber that is difficult to homogenize pre-oxidation.
Academician of the Chinese Academy of Sciences, Academician Shi Changxu of the Chinese Academy of Engineering, Academician of the Chinese Academy of Sciences, and Yang Yuliang, President of Fudan University, etc. More than 30 well-known experts and scholars in the field of carbon fiber at home and abroad have paid great attention to this product's successful industrialization. Experts believe that the dry-jet wet-spinning technology is an efficient spinning technology developed for the ideal PAN-based carbon fiber precursor. It has the advantages of high production efficiency, good carbon fiber quality, low production cost and other wet spinning methods.
High-performance carbon fiber has indispensable advantages in military, aerospace, sports and leisure equipment, oil well mining, construction of large-scale buildings, and transportation equipment. The development of high-performance carbon fiber is not only an urgent need for modernization of national defense, but also a requirement for the development of the national economy.
