Since its establishment, our company has been focusing on developing into a leader in the high-end carbon nanomaterials industry and devoting itself to the research of advanced technology of carbon nanomaterials. As of May 2020, our company has applied for 60 invention patents, published more than 40 professional papers in the industry, published two monograph on carbon nanotubes, obtained 9 national authorized invention patents and 2 international PCT patents, successfully walk out of the research and development path of a technology-based company combining production, teaching and research, break the foreign monopoly, the products sell well all over the world, carbon nanotubes and polymer.
How were carbon nanotubes discovered? Carbon nanotubes were discovered in the laboratory in 1991 by Japanese physicist Yoshiko Hiroshima. As usual, Yoshima Yoshino, who works in the NEC laboratory of Tsukuba in Japan, was observing the carbon fiber made by the arc method by using the transmission electron microscope, and unexpectedly found "carbon nanotubes". Carbon nanotubes are a kind of "tubular" carbon molecules, whose skeleton is honeycomb-shaped structure.
Henan KELAIWEI Nano Carbon Material Co., Ltd invested 0.45 billion yuan to build Dengfeng production base of high-end nano materials. This investment is mainly used to expand the production of 3C/digital whisker carbon nanotubes, high-end far infrared paper, high-end thermal conductivity whisker carbon nanotubes material products and high-end power whisker carbon nanotubes, high-end multiplied whisker carbon nanotubes and thermal conductivity whisker carbon nanotubes and many other products. KELAIWEI company will improve its products to meet the increased needs of KELAIWEI customers.
KELAIWEI Nano Carbon Material Co., Ltd. invested 0.55 billion yuan in 2017 and 2018 to build production research and development centers: Jiangsu KELAIWEI production research and development center and Henan Dengfeng KELAIWEI production research and development center. KELAIWEI Nano Carbon Material Co., Ltd. has recently expanded the production of whisker carbon nano-tube powder in Henan's 13,000-square-meter production base, with an annual output of 300 tons.
Whisker carbon nanotubes belong to coarse diameter and long length. Ordinary carbon nanotubes are short in length and fine in diameter after grinding. Ordinary carbon black belongs to granular conductive agent. Using the principle of composite conductive agent, ordinary carbon nanotubes and carbon black are compounded to produce composite conductive agent paste. The composite conductive agent paste gives full play to the advantages of various conductive agents and can still maintain a good conductive network in high magnification and circulation, it is mainly applied to silicon carbon negative pole and high-rate battery.
A large super wear-resistant rubber tire production company in Jiangxi province is investigating and investigating the performance of thermal conductivity whisker carbon nanotubes produced by KELAIWEI company. The purity of the thermal conductive whisker carbon nanotubes produced by our company is as high as 95.995%, and the graphitization degree is as high as over 90%. The appearance is black split, and the outer diameter is between 30 nm and 200 nm. KELAIWEI company expects more customers to come to discuss cooperation.
The working temperature of the far infrared paper (FIRPs) developed and manufactured by Henan KELAIWEI Nano Carbon Material Co., Ltd. is suitable for the working environment within 300 degrees Celsius, and its far infrared emissivity can reach 99.80% at the same time, it also has higher electrothermal conversion efficiency, it can reach 99.50%, so our far infrared paper can be widely used in the manufacture of electric heating products and equipment, carbon nanotubes and polymer.
