Henan KELAIWEI Nano Carbon Material Co., Ltd. is an international advanced manufacturer of research, development, design and production of high-end nano materials and process equipment. Our company respectively established Jiangxi KELAIWEI company and Henan KELAIWEI company. KELAIWEI company has completely independent intellectual property rights, focusing on high-end nanomaterials technology research and development, process design, equipment manufacturing, technical services and so on.
Since the establishment of Henan KELAIWEI Nano Carbon Material Co., Ltd., relying on the technical accumulation of the company's technical team for more than 20 years, it has achieved a leap-forward and rapid development. KELAIWEI company has developed into a technical backbone enterprise in the high-end nanomaterials industry. In 2008, the company has invested 0.45 billion yuan to expand the production capacity of whisker carbon nanotubes, and this whisker carbon nanotube powder project will achieve an annual production capacity of 300 tons.
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. All the staff of our company are encouraged by the government's on-the-spot support work of "delivering policies, services, elements and confidence". All the staff of our company are full of energy and insist on prevention and control, improve work efficiency, comprehensively promote the resumption of production, accelerate the progress of various projects, and make new contributions to the economic development of our city.
There is a new material-carbon nanotubes are widely used in modern manufacturing industry. The strength of carbon nanotubes can reach 100 times of that of steel. At the same time, its strong thermal conductivity and conductivity can also be compared with Diamond, copper is equivalent to that of Henan KELAIWEI Nano Carbon Material Co., Ltd. It is learned that a large multinational enterprise in South Korea recently invested more than 300 million yuan to expand the capacity of carbon nanotubes, in the future, the competition in the carbon nanotube industry is bound to have a "growing momentum", and the manufacturing process of carbon crystal electric heating plate.
How is carbon nanotubes made by carbon crystal electric heating plate manufacturing process and chemical vapor deposition? Carbon nanotube materials are widely used and have strong properties, but their production is very low and the manufacturing process is complex. Therefore, scientists have continuously improved the manufacturing methods. Chemical vapor deposition method is used to produce carbon nanotubes, and its production efficiency is still relatively high. By chemical vapor deposition, carbon-containing gases are cracked by catalysts to obtain carbon nanotubes.
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.
