After many years of efforts, Chinese scientists have finally overcome the technical difficulties of directly producing polymethyl methacrylate (PMMA) mutant plastic optical fibers from bulk polymerization, and mastered the continuous production of plastic optical fiber technologies. The reporter learned from the Physical and Chemical Technology Research Institute of the Chinese Academy of Sciences on the 16th that the Institute has now produced millions of meters of low-loss mutant plastic optical fiber, which has broken the monopoly position of Japanese companies in the world. In recent years, the demand for global plastic optical fiber has rapidly increased. In 2005, the international sales of PMMA plastic optical fiber have reached billions of dollars. The low-loss PMMA plastic optical fiber that is suitable for data transmission is currently only produced by Mitsubishi Corporation of Japan. Every year, China imports a large amount of PMMA plastic optical fiber from Japan. According to the project's principals, Zhen Zhen and Liu Xinhou, the Institute of Physics and Chemistry of the Chinese Academy of Sciences has mastered the complete set of fiber optic technology from raw material purification and bulk polymerization. Its core technology is high-purity fiber grade PMMA optical molding compound (core material) and skin material preparation technology. During the development process, the Institute of Physics and Chemistry, Chinese Academy of Sciences has developed a new technology for the purification of single molecular diffusion and transfer materials with independent intellectual property rights, and the bulk polymerization of flat-push thin-layer tubular and twin-screw composite systems to produce high-purity fiber-grade PMMA materials. The cladding material technology that is matched with it successfully solves the problems related to industrialization. It is reported that at present, the institute has successfully developed a fully automatic assembly line for producing 100,000 meters of PMMA plastic optical fiber. PMMA optical fiber with a light attenuation of 170-200dB/km has been produced for several months in a stable manner. Cumulative production of millions of meters of low-loss plastic optical fiber has been demonstrated. This industrialization technology has matured. At the same time, the institute also possesses step-by-step PMMA fiber potential with mass production of optical attenuation of 150dB/km, and its product specifications have reached the best level of similar products in the world. The advent of low-attenuation PMMA fiber continuous mass production technology marks China's rank among the world's advanced players in this field. The development of today's information technology is in urgent need of optical fiber materials with large information capacity, and the demand for communication network bandwidth is getting higher and higher. Plastic optical fiber has the advantages of large core diameter, soft texture, easy connection, light weight, low price, large transmission bandwidth, etc., in broadband access network systems, home intelligent network systems, data transmission systems, automotive intelligent systems, industrial control systems, and textiles There are huge market potentials for applications such as lighting, solar energy utilization systems, etc. Worm Gear System Hydraulic Universal Testing Machine Tensile Tester,Bone Plate Testing Machine,Wire Pole Testing Machine,Worm Gear System Testing Machine Jinan Chenda Testing Machine Manufacturing Co., Ltd. , https://www.jncdtester.com
