KELAIWEI specializes in the preparation technology of nanomaterials for more than 20 years. In the past 20 years, Professor Sun Xiaogang's technical research and development team of Nanchang University has continuously output technical achievements. Now KELAIWEI company has helped enterprises in more than 60 countries around the world to solve the required nanomaterials products. The manufacturing equipment and technology of whisker carbon nanotubes researched and developed by our company by ourselves have the dominant advantage of technology at home and abroad. Our company has applied for 106 patents including 9 national authorized invention patents and 2 international PCT patents.
What is nano carbon fiber? Carbon nanofibers are a new type of nanomaterials. Nanometer carbon fiber has rich characteristics: light mass low density, large aspect ratio (100 nm -500 nm), diameter 50 nm -200 nm, stable and strong electrical conductivity, etc, moreover, the production cost is much lower than that of carbon nanotube materials, which is easier to be manufactured in batches and has higher output.
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.
The fourth of the series of "reviewing the development history · encouraging young talents to compete bravely" of KELAIWEI company: chronicle of Events in 2012 professor Sun, the technical leader of KELAIWEI company, began to lead the technical team to develop mass production equipment and improve purity since the synthesis of whisker carbon nanotubes, and finally developed the second generation whisker carbon nanotubes production equipment, the production of our whisker carbon nanotubes reaches 0.5kg/h, and the purification method of carbon nanotubes and its advantages.
Purification method of carbon nanotubes and its advantages, whisker carbon nanotubes have very high graphitization degree, and materials with high graphitization degree generally have good radiation and heat dissipation effect. KELAIWEI cooperated with Dengcao J Company to develop heat dissipation copper foil, the thermal conductivity in Z direction can reach more than 100w/(m · K) by utilizing the heat-dissipating copper foil made of whisker carbon nanotubes and the radiation heat-dissipating characteristic of carbon nanotubes, which can conduct far infrared continuous heat dissipation, the heat dissipation is sustainable and the heat dissipation effect is good. At present, the product is in the pilot test stage for Huawei and other customers.
The market of modern self-heating food develops rapidly. A food company in Sichuan, newly developed heating food during the promotion period, began to look for whether there is a higher performance in the market after comparing the far infrared paper materials of traditional suppliers, the company with low price finally contacted us through the online website of Henan KELAIWEI Nano Carbon Material Co., Ltd. KELAIWEI company insists on supplying customers with high-end far infrared paper and providing considerate after-sales service.
Recently, a large number of customers are using carbon nano-tube paper produced by Henan KELAIWEI nano-Carbon Material Co., Ltd. Carbon nano-tube paper is one of the products obtained by KELAIWEI company after more than 20 years of research on carbon nano-tube technology. Carbon nano-tube paper can be used to make cooling pad in high-power electronic components, can be used as positive and negative electrode material additive of high-end battery, and can be used as gas diffusion layer of battery.
