Professor Sun Xiaogang's long-term research on carbon nanotubes includes the synthesis, modification and filling of carbon nanotubes and the application of carbon nanotubes in the fields of electromagnetic shielding, wave absorption, lithium ion batteries and composite materials. Chairman and general manager of Jiangxi KELAIWEI Nano Carbon Material Co., Ltd. In 1999, it began to produce carbon nanotubes and provided them to the whole world. In 2000, it successfully developed a 5kg carbon nanotube device per day. In 2001, it established Nanchang Sun nanotechnology Co., Ltd. and served as the chairman and CEO, the company is one of the first several companies in the world to industrialize the production of carbon nanotubes (at that time there were only 7 companies in the world that could provide carbon nanotubes products), and the production of carbon nanotubes reached the ton level, users all over the world.
Henan KELAIWEI Nano Carbon Material Co., Ltd. was founded in June, 2018. It is mainly engaged in the research and development and manufacture of whisker carbon nanotubes, and has equipment with annual output of 30 tons of whisker carbon nano tube powder, we have invested 0.45 billion yuan to build the project of whisker carbon nano-tube powder with annual production capacity of 300 tons. This project is carried out in two phases, and the production capacity of each phase is designed to be 150 tons/year, KELAIWEI is committed to promoting the development of the domestic whisker carbon nanotubes industry, nano-carbon coating method.
KELAIWEI company relies on the research and development achievements of the expert research and development team of Professor Sun Xiaogang of Nanchang University in China for more than 20 years to carry out the industrial and mass production application of high-end nanomaterials. After years of unremitting efforts and continuous investment, our company has achieved the production capacity of far infrared heating paper reaching 30 tons per year, and the production capacity of designed whisker carbon nanotube powder production line reaching 300 tons per year, around 2008, 0.45 billion yuan has been spent on production capacity expansion.
Stick to the original aspiration and embrace happiness-5S silver medal certification practical training was successfully held. On April 7th, teacher Zhang conducted 5S silver medal certification training for our employees, and through a series of wonderful trainings such as explanation, Q & A, on-site actual combat simulation, re-explanation, re-Q & A, and re-actual combat promotion, let the staff of our company fully feel the importance of "lean thinking" to the improvement of their work effect, and they all expressed that they would apply the Lean Thinking knowledge gained from this training to daily production work.
The less conductive agent is added, the materials with super conductive properties are always pursued by scientists, and carbon nanotubes are such perfect materials. Tens of thousands of hair filaments are equal to the thickness of a carbon nanotube side by side. The application of carbon nanotubes as a conductive agent performs well in the field of high-end lithium battery manufacturing and application. Only a trace of carbon nanotube conductive agent is needed, it seems that it can have super conductive and thermal conductivity, which is far better than carbon black conductive agent.
As nanoscale carbon materials, what are the characteristics of Carbon Nanotubes? Since it belongs to nanomaterials, it is naturally very, very light (ultra-lightweight quality), which may benefit from its own hexagonal connection structure characteristics. Carbon nanotubes have good mechanical and mechanical properties, the toughness strength is just one hundred times, and it also has very good electrical conductivity and thermal conductivity. It is also widely used in many high-end manufacturing industries, nano carbon coating method.
In the ideal situation, carbon nanotubes belong to SP2 hybridization. Because & pi; The movement of electrons produces electrical conductivity, SP3 and SP hybridization is introduced at the bending place of carbon nanotubes, which affects the electrical conductivity of the product, the whisker carbon nanotubes belong to linear structure, and the product has few structural defects. The defective SP3 and SP are hybrid, and the conductivity of carbon nanotubes can be brought into play to a greater extent, and the conductivity of the product is better, when used in composite materials, the conductivity of materials can be significantly improved.
