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, and the product has high requirements on process control. Carbon nano-paper composite materials.
The market demand for high-end nanomaterials is huge, and Henan clevee nanomaterials Co., Ltd. insists on technological innovation and development, the company has become the market leader of high-end carbon nanomaterials and the research and development team led by Professor Sun Xiaogang, a technical expert of carbon nanomaterials in Nanchang University, has promoted the rapid development of whisker-like carbon nanomaterials and applied for more than 60 patents, the products are exported to more than 60 countries and carbon nano-paper composite materials.
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 headquarter of Dengfeng of Henan KELAIWEI Nano Carbon Material Co., Ltd welcomes the research and guidance work of director Zhao and deputy director Dong of the Municipal People's Congress.

Carbon nanotubes have ultra-high conductivity and other characteristics, which are suitable for building light and excellent conductive networks. The price of multi-walled carbon nanotubes sold in the early stage was as high as 60 USD/gram, which was not inferior to gold at all. In fact, the conductivity and thermal conductivity of carbon nanotube materials are basically the same as those of diamond and copper materials. Due to its good industrial development prospects, many high-tech enterprises in the world are engaged in their production research.
What is special about the catalytic thermal decomposition of Carbon Nanotubes? Since carbon nanotube materials were discovered in the laboratory by Japanese physicists in 1991, world physicists have exhausted what they have learned and synthesized carbon nanotubes in various ways. Catalytic thermal decomposition method adopts carbon organic matter to react through high temperature environment of 400-600 degrees and high temperature environment of 700-1000 degrees. Carbon materials are mixed with solvent water, catalyst and materials, and then filtered and dried after stirring and dipping. After catalytic reaction, after washing and ultrasonic shock, carbon nanotubes are finally produced.
The preparation method of ordinary carbon nanotubes adopts the method of preparing solid catalyst first, and then preparing at high temperature cracking under the action of reducing gas. The solid catalyst commonly used in the catalyst has catalyst carrier, generally, it is not easy to remove, resulting in high ash content. The whisker carbon nanotubes adopt floating gas phase catalysis method, and there is no need to separately prepare solid-state catalyst. The synthesis process cycle is short, and the process is relatively simple, the purification process is high temperature purification with low ash content.
