KELAIWEI company has invested 0.55 billion yuan to carry out deep cooperation with the research and development team led by Professor Sun Xiaogang of Nanchang University in China for a long time. And invested 0.45 billion yuan successively in Henan to build the first phase of whisker carbon nano-tube powder project and the second phase of whisker carbon nano-tube powder project, which made the production capacity of whisker carbon nano-tube powder of Henan KELAIWEI nano-Carbon Material Co., Ltd achieve qualitative improvement, up to 300 tons/year.
Are carbon nanotubes carbon nanofiber materials? Carbon nanotubes are nano-sized carbon materials, and carbon nanofibers are also nano-sized carbon materials, but carbon nanotubes and carbon nanofibers are completely different from each other. Carbon nanotubes have hexagonal structure, and the perfect connection of carbon nanofibers is a wire-mounted material. Henan KELAIWEI Nano Carbon Material Co., Ltd. has in-depth research in the field of nanofiber and looks forward to in-depth communication with you.
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.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has made a technological breakthrough again in the study on the controllability of the growth of whisker carbon nanotubes. KELAIWEI nano-carbon material company can precisely control the length and specific surface area of whisker carbon nanotubes and the diameter of whisker carbon nanotubes. Both Henan KELAIWEI company and Jiangxi KELAIWEI Nano Carbon Material Co., Ltd have applied this technology to the industrial mass production of whisker carbon nanotubes.
Carbon dioxide synthesis carbon nanotubes, increasing energy density is the current difficulty and pain point of lithium ion battery. Compared with granular conductive agent, whisker carbon nanotubes is a kind of fibrous conductive agent, which can reduce the addition amount of conductive agent, due to the flexibility of the whisker carbon nanotubes, the additive amount of adhesive can be reduced. Compared with the complete use of granular conductive agent, the amount of adhesive can be reduced by 0.5~1.0%. By reducing the adhesive, by increasing the proportion of the positive electrode material, the energy density of the battery is improved, and carbon dioxide is synthesized into carbon nanotubes.
The far infrared emission band of the paper produced by our company ranges from 2 nanometers to 20 nanometers, and the electrothermal conversion rate is as high as over 99.5%, which has obvious application effect in the field of thermal products. After our company provided samples for a honeycomb heat exchanger manufacturer in Beijing, the performance of the honeycomb heat exchanger was significantly improved, and the energy-saving effect was obvious after the trial of customers, especially the test of the product quality control department, which could save more than 25% of energy compared with the previous one.
Henan KELAIWEI Nano Carbon Material Co., Ltd found that whisker carbon nanotubes were used to make CNT transparent conductive film for their excellent conductivity. CNT transparent conductive film made of whisker carbon nanotubes has stable chemical performance and excellent conductive characteristics, moreover, it has both thermal conductivity and very good mechanical properties (the hardness of whisker carbon nanotubes is 100 times that of steel).
