A breakthrough in carbon fiber technology is a strategic step

Carbon fiber is a high-performance fiber closely related to national security and national economy. As carbon fiber is involved in the military industry, the complete production process and production equipment of carbon fiber in developed countries are still in a stage of strict blockade and strict embargo. China's carbon fiber equipment manufacturing is later than carbon fiber production, the overall level of the industry is still relatively low, to a certain extent, restricting the development of domestic carbon fiber to high performance and high productivity. In order to accelerate the industrialization of carbon fiber, ease the domestic supply and demand contradiction, reverse the passive situation of carbon fiber in China, promote the textile chemical fiber industry to accelerate structural adjustment, technological progress and industrial upgrading, and promote China's high-performance fiber and advanced composite materials as well as aviation and aerospace. In the development of related industries such as new energy, Zhongfu Shenying began to cooperate with Donghua University in 2006 to develop carbon fiber industrialization and equipment research and development projects.

In May 2016, China's first thousand tons of T800 raw silk was put into production. This was completed by Zhongfu Shenying Carbon Fiber Co., Ltd., Donghua University and Jiangsu Yingyou Textile Machinery Co., Ltd. The results of the project of spinning high-performance carbon fiber industrialization key technologies and independent equipment. The project independently developed dry-jet wet-spun carbon fiber technology, designed and developed key production equipment, and broke the long-term foreign technology monopoly. Zhongfu Shenying has become the third company in the world to realize the industrialization of high-performance dry-jet wet-spun carbon fiber. On September 29, Zhongfu Shenying Carbon Fiber Co., Ltd. held the “1000-ton SYT55 (T800) carbon fiber new line project” in Lianyungang, Jiangsu Province, which was put into operation in Zhongfu Shenying, which marked the entry of Zhongfu Shenying into a new era. A key step in the world of carbon fiber. “Dry-jet wet spinning is the most advanced technology recognized for the preparation of high-performance carbon fiber. Its products are widely used in the aviation field and national defense industry. After years of persistence and unremitting efforts, Zhongfu Shenying has broken the monopoly of foreign countries and achieved independence. Chemical production. Zhongfu Shenying has undertaken a number of key tasks of the National Defense Science and Technology Bureau. At present, the SYT49 and SYT55 carbon fiber independently developed by Zhongfu Shenying have already provided stable and continuous supply for the military industry such as strategic weapons and equipment. Capability.” Zhang Guoliang, Chairman of Zhongfu Shenying Carbon Fiber Co., Ltd., said in 2016 that he accepted the “Textile Light” 2016 China Textile Industry Federation Science and Technology First Prize in the Great Hall of the People.

New filtration system meets major national strategic needs in the field of environmental protection

High-temperature waste incineration, the generated smoke contains dioxin in addition to dust. Dioxin is a primary carcinogen, 900 times more than arsenic, and 130 times more than cyanide. It also causes a decrease in sperm count, early puberty in women, infant and lactation disorders, decreased immune function, decreased IQ, and spirit. Diseases and other hazards. In the world, bag dust removal (BF), activated carbon adsorption (ACR) and catalyst catalytic decomposition (SCR) are commonly used to treat flue gas. Most of China lacks SCR devices, resulting in high-level emissions of gaseous dioxins.

The project, completed by Zhejiang University of Science and Technology and Zhejiang Geertais Environmental Protection Special Technology Co., Ltd., has developed a filtration system that combines dust removal and dioxin catalytic decomposition without changing the garbage incineration conditions. The PTFE fiber with stable chemical properties of the important material for preparing the filter bag is solved, and the dust filtering precision is low, and the problem that the gaseous dioxin cannot be retained is solved. The technology can be widely used in industrial production of coal-fired power generation, garbage incineration, cement, metallurgy and other flue gas containing a large amount of dust, so that the ubiquitous and indispensable atmosphere in people's lives is a little healthier. It is worth mentioning that the project is combined with industry, university and research, combined with capital strength, and close cooperation between the parties is the guarantee for the smooth implementation of the project. In addition, the implementation of the project has improved the production process and equipment level of environmentally friendly filter materials in China, laying a material and technical foundation for the development of China's international advanced emission standards , and meeting the important strategic needs of the national environmental protection field is of great significance.

Ultra-high speed digital printing significantly reduces sewage discharge

The printing and dyeing wastewater generated during the traditional printing and dyeing process has a long production cycle and low printing precision, which has seriously hindered the sustainable development of China's printing and dyeing industry . The ultra-high-speed digital printing is formed once, the production cycle is short, the printing precision is high, the batch consistency is good, and the use of chemical dyes and sewage discharge can be greatly reduced. Ultra-high-speed digital printing has major technical problems such as large data flow, easy deformation of printed fabrics, easy clogging of nozzles, and difficulty in automatic detection of printing quality. Its technology has been monopolized by Japan and the European Union , and it is difficult to promote in China. Ultra-high-speed digital printing equipment with independent intellectual property rights .

Under the support of the National Science and Technology Support Program and the provincial special project, the project is the first in China to form an industry-university research team consisting of Zhejiang University, Hangzhou Honghua Digital Technology Co., Ltd., Ningbo University and Zhejiang University of Science and Technology. The key technology of equipment has been developed, and a real-time parallel processing engine for digital printing data has been invented, which realizes ultra-high-speed real-time processing and transmission of digital printing data. Invented the video-based problem for the problem of fabric deformation and nozzle clogging during printing. The real-time monitoring and control method of the printing process; the automatic detection method of the quality defect of the printed image based on the image quality evaluation model was invented, and the working state of the device was remotely monitored through video coding and network transmission, and the ultra-high speed digital was successfully developed. Printing equipment. The products and technologies of the project were included in the “Twelfth Five-Year Plan” of the Industrial Energy Conservation Department of the Ministry of Industry and the “Environmental Protection Technology Catalogue encouraged by the State” of the Ministry of Environmental Protection, which made important contributions to China's energy conservation, emission reduction and environmental protection. Experts believe that the technical achievements have filled the domestic gap and the overall level has reached the international leading level.
