The research and development cycle of whisker carbon nanotubes is long, and it is not easy to achieve a breakthrough in a short time. Ordinary carbon nanotubes all use solid catalysts to deposit the catalysts on the surface of carrier materials, after calcination and reduction, carbon nanotubes are synthesized by introducing hydrocarbon gas. Compared with traditional carbon nanotubes, the process of carbon nanotubes is more complicated, improper regulation and control will easily lead to the growth of non-linear ordinary carbon nanotubes. The product has high requirements on process control, carbon nano heating and graphene heating film.
Henan KELAIWEI nano carbon material company is a high-tech company co-founded by the technical team led by Professor Sun Xiaogang of Nanchang University and Zhengzhou Dengcao group. Henan KELAIWEI Nano Carbon Material Co., Ltd. has an initial investment of 0.55 billion yuan. After its establishment, KELAIWEI will own Henan company and Jiangxi company. The company has built a 300-ton whisker carbon nanotube powder project, which will be completed in two phases and will supply high-end products for China's carbon material industry.
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.
KELAIWEI company applies for national authorized patent invention. As of March this year, KELAIWEI company had obtained four national authorized patents. Henan KELAIWEI Nano Carbon Material Co., Ltd. is a technical company. At the beginning of its establishment, it paid great attention to the formation of technical team, capital investment and the manufacture of advanced equipment and technology. KELAIWEI company, which has accumulated technology for 20 years, is bound to make further achievements in technology research and development.
Carbon Nano heating and graphene heating film, the application field of carbon nanotube materials is being accelerated. Because it has a conductivity of more than ten percent higher than that of traditional materials, its conductivity and thermal conductivity can be equivalent to that of copper and diamond. At present, it has been used by automobile manufacturers to manufacture automobile parts, battery manufacturers to manufacture high-end lithium batteries, and aviation industry to manufacture aircrafts...... Henan KELAIWEI Nano Carbon Material Co., Ltd. has increased the production of whisker carbon nanotubes to meet the market demand.
A brief analysis of the application of carbon nanotubes in electrochemical devices. The electrochemical performance of carbon nanotubes is excellent. Carbon nanotubes are therefore used to make supercapacitors. Compared with traditional capacitors, the capacity of capacitors made of carbon nanotubes is doubled, reaching Farah level. Scientific Practice has proved that a gram of carbon nanotube capacitor can store 15F to 200F. Thanks to the strong performance of carbon nanotube capacitors, supercapacitors up to several thousand Farah have been manufactured.
The general ash content of ordinary carbon nanotubes is above 1%, and the ash content of whisker carbon nanotubes can be controlled below 0.1%, which has extremely low ash content and higher purity of carbon content, the high ash content of ordinary carbon nanotubes is mainly due to the need to use catalyst carrier in the synthesis process. Catalyst Carrier is generally not easy to remove at high temperature, and there is no need to use catalyst carrier in the synthesis of whisker carbon nanotubes, in the process of high temperature purification, the catalyst can be completely removed, and the ash content is generally the residual extremely low metal oxide.
