Boldly test the waters of new materials, open the new door of graphene industry
Release time:
2019-03-29
What is graphene? Ordinary citizens may be at a loss for this question. But there is a Liuyang people, but with this emerging material with six years. From drilling into an unfamiliar industry to open the door to a new industry, he is the first in the field of graphene industrialization in Liuyang, "eat crabs" people. His name is Liu Jianzhong, Liuyang High-tech Zone, Hunan Xiangxian Technology Co. Graphene has excellent electrical conductivity, thermal conductivity, large specific surface area, high transmittance and other excellent characteristics, in many applications are "potential shares". 2012, Liuyang Hi-tech Zone, "old" level enterprises Xiangxian Technology (due to the "Graphene"), "Graphene", "Graphene", "Graphene", "Graphene", "Graphene", "Graphene", "Graphene" and "Graphene".

From drilling into an unfamiliar industry to open the door to a new industry, he is the first in the field of graphene industrialization in Liuyang, "eat crabs" people. His name is Liu Jianzhong, Liuyang High-tech Zone, Hunan Xiangxian Technology Co.
Graphene has excellent electrical conductivity, thermal conductivity, large specific surface area, high transmittance and other excellent characteristics, in many applications are "potential shares". 2012, Liuyang Hi-tech Zone, "old" level enterprises Xiangxian Technology (due to the needs of the company's management, the company's management). In December 2016, Hunan Jinyang Olefin New Material Co., Ltd. was registered), resolutely chose to transform from copper processing to the new material graphene industry. After six years of research and development, Xiangxian science and technology in last year built graphene materials and lithium electronic anode materials production line, and officially put into production, and now has realized the quantitative production of graphene materials products, to reach the cooperation of more than ten enterprises. Now it has realized the quantitative production of graphene material products, and more than ten enterprises have reached cooperation.
R & D investment of several million dollars per year
Six years to realize the quantitative production of graphene products
"From 2012 onwards, each year is a few million dollars of R & D investment, until last year's production, the heart of the apprehension came down." Liu Jianzhong said, graphene materials R & D test line has been built as early as 2014, but graphene product production line until 2018 to put into production, these years have been the input stage.
As a new material that is still very "young", the research and development of graphene materials and the establishment of production lines is not easy. "We are based on independent development, supplemented by cooperative development with universities." Xiangxian science and technology deputy general manager Wen Zhongqiang said, he came to the company more than two years, specializing in graphene materials and related applications of product development, industry standards are not perfect and the lack of equipment, technology is a big problem hindering their research and development.
"The R&D cycle of graphene is particularly long, and some indicators have no way to conduct quantitative testing until now." Wen Zhongqiang said, because this is a new industry, research and development personnel and equipment are very lack of, whether it is the international or domestic graphene industry, graphene standards have imperfections, resulting in the development of materials sometimes they can not judge whether the material in the end is not so.
In the whole graphene R & D and application development, the most vexing is actually the process problem. "There was a time when the R & D process required the use of ultra-high pressure equipment, but we searched for a long time and could not find it." Wen Zhongqiang said, because the industry has not yet appeared "template", no one to tell you which equipment should be used, which process, so the R & D team spent 60% of their energy in the process of exploring, in which the time spent on this is much more than the time to do the experiment, in the past few years, the laboratory just like a second R & D personnel "The laboratory has become the second home of the R&D staff in the past few years.
Continuously overcoming the difficulties in research and development and equipment, in 2018, Xiangxian Technology's graphene productization production line was successfully put into production, which means that the developed graphene products can be mass-produced. "The quality of the products is more stable and able to meet the needs of customers." Wen Zhongqiang said, this is not only to give everyone a "pill of confidence", but also let them have more confidence in the graphene industry.
Wide range of applications
Has reached cooperation with more than ten enterprises
Graphene is a two-dimensional material consisting of carbon atoms in a hexagonal honeycomb lattice of flat films, only one carbon atom thickness. It is almost completely transparent, but very dense, even the smallest gas atom (hydrogen atom) is difficult to penetrate. In the industry, graphene is known as the new material with the thinnest thickness, the highest hardness and the best thermal and electrical conductivity found in nature so far, with a strength 200 times that of the highest-strength steel and a thermal conductivity 8 times that of silver.
Follow Liu Jianzhong's footsteps into the company's finished products showroom, the height of different, different sizes of glass bottles, respectively, containing powdered, slurry and water emulsion graphene material products, the application of the product is also displayed in front of the booth. Liu Jianzhong will be a side of the mural on the electricity, more than ten seconds will feel the heat coming from the mural. "By adding graphene conductive paste, it can achieve a good heat dissipation effect." Liu Jianzhong said that under certain conditions, it can replace air conditioning as a heating tool.
In addition, applying graphene materials in different products will also achieve different results. Graphene modified battery, not only makes better conductivity, faster charging, but also able to increase battery capacity; graphene mask through the electrical signal can realize the face massage at the same time, but also the face related information feedback to the user; graphene anti-corrosion coatings
