The research and development team of Henan KELAIWEI nano-Carbon Material Co., Ltd. has been striving for the high-end nano-material industry of the motherland for more than 20 years, and finally relies on technology self-research, patent invention, high-end manufacturing technology, professional services expand overseas nanomaterials market in more than 60 countries and regions. KELAIWEI will build the project of "whisker carbon nano-tube powder" with an annual output of 300 tons, which will surely supply customers with high-end products and advanced technical services stably.
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.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has established cooperation with Zhengzhou University of Light Industry, Donghua University, Nanchang University and other universities, among which the technology research and development team led by Professor Sun Xiaogang of Nanchang University has been engaged in research for more than 20 years, he co-founded Henan KELAIWEI Nano Carbon Material Co., Ltd with our company. Therefore, our company has profound technical deposits, and the research and development of Far Infrared paper (FIRPs) products, whisker-like carbon nanotubes and other materials sell well at home and abroad.
The editor of the planning department of KELAIWEI company is very happy to announce once again the new achievements of technology research and development obtained by our technical team: technical patent for synthesis of carbon nanotube materials the full name of this technology is "synthesis device for automatic continuous production of whisker-like carbon nanotubes". Authorized patent number obtained by Henan KELAIWEI Nano Carbon Materials Co., Ltd: ZL201210304345.7, carbon nanotubes with positive charge on the surface.
Lithium-ion batteries used in new energy electric vehicles usually have low discharge capacity and slow charging speed at low temperature, which is not conducive to the use of lithium-ion batteries in low temperature areas. The Battery bag heating sleeve made of far infrared heating paper is used, the lithium ion battery can be heated instantaneously, and the lithium ion low-temperature battery can be self-heated from-40℃ to 100℃. At present, the company has established contact with Ningde times, BYD and other companies, the product has been tested and the test results are good.
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.
Far infrared paper (FIRPs) with excellent performance developed by Henan KELAIWEI Nano Carbon Material Co., Ltd. is being purchased by manufacturers at home and abroad. Using far infrared paper in the field of heating and keeping warm can improve the product's keeping warm performance, it is widely used in the field of food heating products manufacturing and automobile power supply boiling water equipment, and is also used as far infrared equipment manufacturing by health therapy equipment manufacturers, which has become an indispensable material in many manufacturers' production, carbon nanotubes with positive charge on the surface.
