“Without quantitative production, experimental materials will not have life.†This is what the graphene discoverer, Professor Andre Heim of the University of Manchester in England once said. Indeed, when an industry or an industry does not form a relatively complete industrial chain, then it is not a field with “lifeâ€, and it is also true for graphene that is still in the laboratory. When talking about graphene, people in the industry will give a thumbs up and say that this is a "good thing", it is a magical substance that can change the world. However, it is such a magical substance that has been developed in China for more than a decade, but still faces a deadly bottleneck of limited production. In fact, not only is China facing such a short board, the widespread use of graphene has now become a problem worldwide. The advantages of graphene, which is known as “industrial MSGâ€, are self-evident, but why is the development of industrialization “walkingâ€? Graphene walked on the "altar" and said that graphene was on the "altar" and there was no exaggerated composition. As the former director of the Energy Development Bureau of the National Development and Reform Commission and the State Council Counselor Xu Dingming said at a relevant meeting recently, the graphene field will make great achievements in specific aspects such as energy conservation, new energy and green energy. Academician of the Chinese Academy of Sciences recently said in an interview with the media that in the future, graphene materials similar to carbon fiber will be used in high-end equipment manufacturing such as aerospace and graphite-like materials similar to plastics will be widely used in people's daily lives. It may even become a universal material like plastic in the future; on the other hand, graphene materials similar to silicon materials will be applied to the field of integrated circuits, which is expected to accelerate the development of the integrated circuit industry and promote the re-industry revolution of the entire information industry. According to the reporter, graphene is a two-dimensional crystal that is stripped from graphite and composed of carbon atoms and has only one atomic thickness. Its natural properties are by far the thinnest and strongest among the materials known in the world, and have excellent electrical conductivity, thermal conductivity and light transmission. It is reported that graphene-related technology research and development has been included in the new material field key support projects in China, the United States, Japan, Japan and South Korea. Li Yichun, secretary-general of China Graphene Industry Technology Innovation Strategy Alliance, pointed out in relevant conferences: Graphene electrothermal membrane technology is a major breakthrough in the development of graphene industry, and it is one of the most effective ways to replace traditional heating methods. It is clean and convenient. The social benefits of energy saving and emission reduction, the alliance's "graphene energy replacement working group" function is to coordinate and integrate the products and technologies of graphene in electric heating, and cooperate with local governments to build "graphene electric energy substitution demonstration project". Contributing to the national electric energy substitution strategy, on the other hand, it has also strongly promoted the development of the graphene industry. In the interview, the reporter learned that from 2013, many advantages of graphene have also entered the field of research of new materials and new technology experts. The development of graphene by governments at all levels in China has also risen to an unprecedented height. The relevant departments even said that graphene technology is likely to receive key support in the 13th Five-Year Plan. It is conservatively estimated that the global graphene industry will exceed 100 billion US dollars in the next 5 to 10 years. In an interview with the reporter of China Sankei Shimbun, Zeng Haiwei, dean of the South China Institute of Wisdom Innovation, said that from the perspective of macroeconomic policy, the development of graphene in China has received strong support from the state and local governments at all levels; The application of graphene in batteries and other fields is more prominent. Graphene is getting more and more attention from the capital market. Listed companies are also keen to invest heavily. Therefore, it is an indisputable fact that graphene is on the altar. The 2016 data released by the China Graphene Industry Technology Innovation Strategic Alliance shows that by 2020, the global graphene market will exceed 100 billion yuan, and the new energy industry's lithium battery and supercapacitor market will exceed 53.4 billion yuan, of which China accounted for More than 50%-80%. Industrialization application "fault" Although graphene is promising in energy-saving and other related fields, how to achieve quantitative application is always a real problem. “Graphene is still in the concept of speculation, which means that it is still in the laboratory stage.†Lin Boqiang, dean of the China Energy Economic Policy Research Institute of Xiamen University, said in an interview with the reporter of China Sankei Shimbun, the current cost of graphene, The products and business models produced are still unclear, and commercial development is almost zero. In Li Yichun's view, at present, domestic graphene products are mixed, and some companies are speculating on the stock price with the concept of graphene, and there is speculation in the market. At present, no more than five domestic companies are actually operating graphene as a growth point. In the interview, the reporter learned that at a recent industry seminar, the hot topics discussed by relevant experts were how to obtain graphene with high purity; on the other hand, the point of discussion was whether it could be applied to all walks of life. According to the reporter, at present, there are more than 400 companies engaged in R&D, production and application of graphene, which accounts for about 3/4 of the total graphene industry in the world. Researchers in the industry have said that at present, the entire industrial chain of graphene industry has taken shape, covering all aspects from raw materials, preparation, product development and downstream applications. However, due to the small number of leading enterprises and relatively small scale, it has restricted the further development and improvement of the entire industrial ecosystem. However, in Zeng Haiwei's view, although China's graphene research started late, it has developed rapidly. In recent years, the number of domestic patent applications and the number of applicants has grown very rapidly, and the technical topics involved are also more extensive. "From the perspective of the patent owner, most of these patents are in universities and research institutions, and the actual market application ratio is still relatively low. At the same time, some of the graphene core patents are still in the hands of a few big countries." Zeng Haiwei said that in recent years The global graphene technology patent is shifting from the preparation process to the downstream application. In the future, graphene is expected to accelerate the integration with the downstream application industry and promote the industrialization of graphene. Some industry observers believe that with the continuous introduction of relevant policies and the continuous construction of industrial alliances and innovation platforms, it is expected that the layout of graphene industry chain will be more perfect in 2018. It is expected that the graphene industry will shake the trillion industry chain in 2020. . Graphene faces technology "stretching" Previously, some analysts believe that although graphene is sought after by the capital market, in fact, China's existing graphene industrialization presents a phenomenon of polarization. Low-end products based on graphene powder, such as functional coatings, composite materials, electrode materials and structurally reinforced materials. Part of the people have been initially industrialized, but the scale is small, the technical content and added value are relatively low. "To put it bluntly, the reason why graphene can not be widely used, in the final analysis, is still a technical problem." Lin Boqiang said that at present, graphene needs several breakthroughs in technology. For example, high quality, low cost, purification technology, application technology and environmental protection. And these technologies have yet to be studied. Previously, some researchers believe that in the development of the entire industry, market applications are derived from backward development, and industrial technology also lacks guidance, so market demand has not yet opened. The researchers also believe that graphene requires a large amount of capital in the initial investment and has a long cycle. Moreover, the production cost of graphene also needs to be further reduced. In this interview, some experts talked about the premise of graphene technology, and another thing worth noting is that graphene will bring greater risks to the environment during the production process. Gao Changchen, chairman of Shenzhen Solid Waste Environmental Protection Technology Co., Ltd., said in an interview with the reporter of China Sankei Shimbun that graphene can be divided into low concentration, high concentration and nano-sized particles, which have biotoxic effects on plants, animals and microorganisms. . Low-concentration graphene has a promoting effect on organisms, and high-concentration graphene has an inhibitory effect, while nano-scale graphene can enter cells to affect cell activity. Gao Changchen said that graphene will produce high water consumption and produce a large amount of waste acid in the production process, which not only increases the cost of pollution control, but also poses great risks to the environment. Environmental regulatory agencies should implement environmental protection planning and design for graphene production enterprises, strictly study and judge, and minimize environmental risks. Earlier, the experts of the CCID Research Institute of the Ministry of Industry and Information Technology also discussed in a meeting on the development of graphene industry that the preparation method of graphene will bring some environmental impact, resulting in ecological damage, plus graphene enterprises. The environmental protection facilities are that the government supervision is not in place, so there is still great pressure on environmental protection. For the destruction of graphene environment, Sharon Walker, an environmental engineer at the University of California, USA, studied the environmental risks of graphene entering water. The research report was published in the journal Environmental Science Engineering a few years ago. According to the study, in a liquid similar to groundwater, graphene oxide will sink and will not cause damage to the waters. However, in a liquid similar to surface water, graphene oxide does not sink, it adsorbs to the organic matter produced by decaying plants and animals, and then floats with them. Then, the chances of animals and people taking graphene oxide are greatly increased. It is worth mentioning that at present, the controversy over graphene in the industry is mainly due to the pollution of graphene to producers. In fact, it does seem to be a false proposition that graphene will not pollute the environment during the production process. Aside from graphene, in fact, any chemical products will produce toxic and harmful substances in the production process. As a pollution-related enterprise, the most important thing depends on whether the enterprise can simultaneously develop pollution while pursuing development. For example, environmentally-friendly facilities with high technical content and strict management of normal operation of daily facilities are all measures. At the same time, it is especially important for companies to have local regulatory authorities not in place. "The fierce will be sent to the war, and the prime minister will start in the county." Although the current graphene is still in the technical concept period, one day its technology will be broken, graphene will also usher in explosive growth, and for environmental problems, it is believed that under the supervision of relevant state departments, the pollution problem Will be solved.Mining Truck Parts,Mining Machine Parts,Mining Tipper Truck Parts,Mining Truck Spare Parts
