On April 24, Bai Chunli, executive vice president of the Chinese Academy of Sciences, accompanied by Deng Maicun, Deputy Secretary General of the Chinese Academy of Sciences and general manager of Guoke holdings, Li Ding, director of the Bureau of infrastructure, and relevant leaders of the Chemical Institute, came to Zhongke printing brush Co., Ltd, A survey was conducted on the research and development site of a new generation of printing plate making technology based on nano materials, which is undergoing intensive industrialization experiments here

Bai Chunli and his entourage investigated the experimental site of green printing plate making technology of nano materials. Bai Chunli pointed out that since the outbreak of the financial crisis, the CPC Central Committee and the State Council have made a series of combinations to deal with the crisis, and the tearing and expanding speed is directly related to the stretching speed of the gripper. They have also taken an important measure in the opinions of the State Council on giving play to the role of scientific and technological support to promote steady and rapid economic development. Recently, in order to implement the relevant requirements of the CPC Central Committee and the State Council and mobilize the whole academy to serve the development of enterprises, the Chinese Academy of Sciences also timely launched the special action plan for scientific and technological innovation to promote economic and social development, and included the green printing and plate making technology originally created by the Institute of chemistry of the Chinese Academy of Sciences in the action plan

it is understood that the printing industry is one of the industries that have an important impact on China's national economy. In 2007, the total output value of China's printing industry exceeded 400billion yuan, accounting for about 2.2% of GDP; In 2008, the total output value of China's publishing industry exceeded 850billion yuan, equivalent to the output value of the automobile industry. At present, the principle of the mainstream plate making technology in China and the world is still the photosensitive imaging of plates. Therefore, it is inevitable that there are complex processes and cumbersome processes such as photosensitivity, development, fixing, and washing, which are costly, time-consuming, and environmental pollution caused by chemical cleaning

Bai Chunli pointed out that the emergence of Laser Phototypesetting Technology has made the printing industry bid farewell to lead and fire, but it has not yet solved the pollution and cumbersome process problems; Although the computer direct plate making technology, which represents the development direction of advanced printing plate making in the world, omits the steps of film, its technical principle is still the photosensitive imaging of plates. At present, China's printing plate making industry discharges hundreds of thousands of tons of heavy metal waste liquid every year, including 600 tons of silver and tens of tons of aluminum, causing serious waste of resources and environmental pollution. In the current situation of the financial crisis, this series of problems has also become a key bottleneck for the printing industry to adjust the structure, promote development and deal with the financial crisis

in recent years, researchers from the Institute of chemistry of the Chinese Academy of sciences have invented a new generation of printing and plate making technology based on nano materials. Through the development of new materials industry in our province, the main innovation body is the new nano transfer materials of scientific research institutes, which can directly print and plate making, so as to realize the real digitalization of printing and plate making and see what you hit. The relevant project leader said that at present, this technology has obtained a number of core patents, has relatively systematic independent intellectual property rights, and has preliminarily completed the design and construction of the transfer material pilot line. Through cooperation with relevant companies of Zhongke printing, the R & D unit has successfully used this technology to carry out many monochrome and color printing experiments on different types of printing machines, and is conducting relevant pilot experiments

Bai Chunli said that the scientific research personnel of the Institute of chemistry of the Chinese Academy of Sciences first proposed and developed a green printing plate making technology completely without photosensitive process, which is a revolutionary technology in the printing industry. In July 2007, the Party group of the Academy discussed the exploration of major projects through the application of nanotechnology in several important fields. Among them, the green direct printing plate making technology based on the consumption demand of nano materials, which shows rigid materials, is one of the project topics. After more than a year of efforts, the research has made important progress and solved some key problems, such as the completion of the development of direct plate making plates: through the systematic research on the surface structure of plates and nano composite transfer materials, the super hydrophilic plates with a water contact angle of less than 10 degrees have been successfully developed. Through the synergy with nano composite transfer materials, the transfer area has changed from super hydrophilic to super lipophilic, It meets the requirements of direct plate making and printing process; The development and pilot design of nanocomposite transfer materials have been completed: nanocomposite transfer materials are the key materials that affect the plate making accuracy and printing resistance; Through the realization of nano and micro scale wettability transformation, the image and text areas and non image and text areas with opposite wettability (super lipophilic/hydrophilic) are formed to directly form the base plate for printing, which completely abandons the idea of photosensitive imaging, effectively shortens the plate making process, greatly reduces the cost, and the used plates can be recycled. It is a green high-quality and fast plate making technology. Therefore, it is hoped that the R & D units can continue to cooperate closely with the industry, improve the relevant process level, go to the market as soon as possible, and fundamentally get rid of the passive situation that China's high-end printing industry is led by foreign enterprises; Form core technologies with international competitiveness, provide a broader space for independent innovation and sustainable innovation, and walk out of the road of leapfrog development with the help of the "peacock plan". He emphasized that relevant national departments should further increase investment, support the large-scale industrialization of relevant nano materials, promote the system optimization and technology integration of the new generation of printing plate making technology, and promote the industrial structure adjustment of China's printing industry, so as to make substantive contributions to the response of relevant industries to the financial crisis

according to the relevant person in charge of the Institute of chemistry, Chinese Academy of Sciences, after more than a year of efforts, the research has completed the development of direct plate making, the development and pilot design of nanocomposite transfer materials, developed a direct plate making prototype, and cooperated with Chinese Academy of Sciences to successfully carry out many printing experiments. At present, the monochrome plate making accuracy of the technical laboratory can reach 175 lines, and the plate making accuracy with industrial raw materials can reach lines, with more than 50000 single board prints

Bai Chunli said that although the research at the laboratory stage of the technology has been basically mature, and some technologies have reached the pilot test stage, it is a complex and arduous process from laboratory technology innovation to industrialization. Many engineering links such as technology integration, production process and quality control must be solved, and a complete system of quality standards must be established to form a replicable industrialization promotion technology and scheme. At present, the Chinese Academy of Sciences has begun to prepare for the establishment of the nano material green plate making technology engineering center of the Chinese Academy of Sciences, but it is also necessary to establish a system pilot test line including transfer materials, plate preparation, equipment modification, plate making and printing test workshops, and formulate a time roadmap, define the time nodes, form a perfect technology integration and demonstration scheme, and accelerate the large-scale industrialization

finally, Bai Chunli stressed that the green printing plate making technology may fundamentally solve the problems of environmental pollution and resource waste in China's printing plate making industry. He hoped that through the close cooperation between R & D personnel and relevant enterprises, the nano material green plate making technology engineering center of the Chinese Academy of Sciences under preparation would be built into the original place of China's environmentally friendly printing new material technology, the drafting of standards for environmentally friendly printing materials and technologies It is the integration place of authoritative evaluation and testing institutions and the training place of relevant senior professionals. The Chinese Academy of Sciences should continue to provide technical support and talent support for improving the independent innovation ability and international competitiveness of China's printing industry, and make a real contribution to scientific and technological innovation for China's printing industry to finally bid farewell to pollution and cast aside the dark (without exposure)
