In China's nano carbon Tube Market, Professor Sun Xiaogang has been engaged in the research of carbon nanotubes for a long time, including 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 and the Chinese carbon nano tube market.
Ultra-high purity whisker carbon nanotube powder products, high-end far infrared heating paper products, A series of carbon-based nanomaterials, such as technology-innovative carbon-based composite derivative products and high-end whisker carbon nanotube conductive paste, have completely independent intellectual property rights, henan KELAIWEI Nano Carbon Material Co., Ltd. supports technological innovation to meet the needs of high-end nano material customers.
The annual spring sports meeting of Henan KELAIWEI Nano Carbon Material Co., Ltd. was held on schedule in the staff sports ground of Dengfeng production center company. Through the fun sports meeting, KELAIWEI employees can exercise the solidarity and cooperation spirit of KELAIWEI employees, promote the communication between different departments of KELAIWEI, and make KELAIWEI employees pay attention to sports health, KELAIWEI company not only attaches importance to staff skill training, but also always pays attention to the health of the company's employees.
Once discovered, carbon nanotubes are destined to be widely used materials in high-end manufacturing industry. The high-end equipment manufacturing industry pursues materials with higher strength, higher toughness, higher electrical conductivity and higher thermal conductivity. Instead, it becomes stronger with the progress of science and technology, and carbon nanotubes are exactly such materials. KELAIWEI is looking forward to in-depth cooperation with you in the field of carbon nanotubes.
A brief introduction to the fabrication of carbon nanotubes by arc method. Carbon nanotubes were first discovered by Japanese physicists, and the arc method was also first invented by Japanese scientists. The arc method is to rearrange the structure of carbon atoms in the high temperature environment produced by the arc caused by the graphite electrode of yin and yang poles in the reaction chamber containing the pressure inert gas, so as to obtain a single-wall carbon nano-tube. Since then, the arc method has been continuously improved and perfected day by day.
Whisker carbon nanotubes can use powder alone, and the length of powder can reach up to 10μm. In the grinding process of ordinary carbon nanotubes using sand Mill, the length of carbon nanotubes will become shorter, generally, the length of carbon nanotubes after grinding is generally 0.2~2 μm. In long-cycle and high-rate lithium ion batteries, the charging and discharging battery materials will expand, using a longer-length conductive agent can maintain the conductive channel during expansion, and the cycle and magnification performance of the battery are improved.
