China's long-chain nylon production has successfully leapt to 10,000 tons. The reporter learned from Shandong Guangsheng New Materials Co., Ltd. last week that after one month of trial production, China's first 10,000-ton-class long-chain carbon nylon production line was officially put into operation at the company. The advent of domestic long carbon chain nylon breaks the dominance of imported products and has important demonstration significance for the development of high-performance engineering plastics in China. According to the company's chief engineer Fang Yongmin, the production line to produce nylon 1212, nylon 1012, nylon 1313, nylon 1014, nylon MXD12-based, raw materials using biological method long carbon chain dibasic acid, with low cost, variety, performance High, versatile features. At present, the product has been trialed by a number of domestic and foreign customers, and has achieved satisfactory results. The market price of the product is 10%~20% lower than that of imported products. The long carbon chain nylon has excellent performance, wide application, and high added value. However, due to complicated process routes, harsh production conditions, many synthetic steps, and high cost factors, long-term carbon nylon production in China has been almost blank. China consumes a large amount of foreign exchange long carbon chain nylon annually, and the current import price has reached more than 100,000 yuan per ton. In order to promote wider use of long carbon chain nylon in China, and get rid of the difficulties caused by imported products, in 2011, Guangsheng Company and the Key Laboratory of Engineering Plastics of the Chinese Academy of Sciences jointly established a long carbon chain nylon research and development technology. High-performance engineering plastics research and development center. Prior to this, Zibo Guangtong Chemical Co., Ltd. (the parent company of Guangsheng Company) has continued the practice of R&D and industrialization of long-chain carbon nylon for 15 years. The system has overcome the stability control of the polymerization process and the flexible control and accuracy of the polymerization degree. Control and other technical problems, the long-chain nylon in the automotive, energy, coating, spinning, clothing and other fields of application research has also made real progress, the company currently has seven long-chain nylon national invention patent technology. According to reports, long carbon chain nylon mainly includes nylon 11, nylon 12, nylon 1212, nylon 1012, nylon 1313, nylon 1014, nylon MXD12 and other series products, with low water absorption, good low temperature resistance, dimensional stability, high strength, toughness Good, wear-resisting and shock-absorbing advantages have an irreplaceable role in key areas such as automobile, communications, machinery, electronic and electrical, aerospace, and military. During the "12th Five-Year Plan" period, the rapid development of solar energy and ocean engineering and other fields will also greatly increase the demand for long carbon chain nylon.
