At present, there are four companies in the world that can carry out mass production of whisker carbon nanotubes, which are Japan SHOWA SENKO, Taiwan rijiang, US Applied Sciences and our company respectively. Among them, Japan has the largest production of SHOWA SENKO, up to about 500 tons. The technology and equipment of whisker carbon nanotubes developed by our company are at the same level as SHOWA SENKO. Only KELAIWEI company can produce mass production in China, and its technology belongs to international advanced, which is the mainstay in China.
KELAIWEI company insists on mastering the core technology of high-end nanomaterials. High-end nanomaterials have broad market application prospects and are also essential materials for the development of national high-end manufacturing industry. With the dream of serving the motherland and enhancing the competitiveness of China's manufacturing industry, Professor Sun of Nanchang University led the team to break the foreign monopoly and applied for more than 60 patents, two monographs and 9 national invention patents, there are two international PCT patents. Our company will continue to make efforts to research and manufacture high-end nanomaterials to win honor for our country.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has always maintained close technical cooperation with first-class domestic universities and scientific research institutions such as Zhengzhou University of Light Industry, Donghua University and Nanchang University. The high-end nanomaterials products developed by KELAIWEI company have broad application scenarios in high-end lithium ion energy storage battery manufacturing at home and abroad, electrothermal converter preparation, high-end nanomaterials and other industries.
KELAIWEI company welcomes the May 4th Youth Day. The new force of KELAIWEI Nano Carbon Material Co., Ltd. lies in young employees, and the future of the company belongs to young talents. Many outstanding young employees are active in the R & D, workshop, administrative human resources and other departments of KELAIWEI company. KELAIWEI company always pays attention to the rapid growth of young employees. KELAIWEI company pays attention to "bringing the old with the new" and builds the "backbone" strength of young employees.
Low-carbon nanometer, single-walled carbon nanotubes are high-purity carbon nanotube materials, single-walled carbon nanotubes are very fine, the fineness of tens of thousands put together is equal to the fineness of a single-walled carbon nanotube, therefore, carbon nanotubes are used to make precise tiny components. Some scientists have made small computers using single-walled carbon nano controls. Nanomaterials with light weight, small size, rich performance and high stability are highly sought after by modern industrial society.
How is carbon nanotubes made by chemical vapor deposition? Carbon nanotube materials are widely used and have strong properties, but the output is very low and the manufacturing process is complex. Therefore, scientists have continuously improved the manufacturing method. Chemical vapor deposition is used to produce carbon nanotubes, its production efficiency is still relatively high. The chemical vapor deposition method can crack the carbon-containing gas through the catalyst to obtain carbon nanotubes and low-carbon nanometers.
In the ideal situation, carbon nanotubes belong to SP2 hybridization. Because & pi; The movement of electrons produces electrical conductivity, SP3 and SP hybridization is introduced at the bending place of carbon nanotubes, which affects the electrical conductivity of the product, the whisker carbon nanotubes belong to linear structure, and the product has few structural defects. The defective SP3 and SP are hybrid, and the conductivity of carbon nanotubes can be brought into play to a greater extent, and the conductivity of the product is better, when used in composite materials, the conductivity of materials can be significantly improved.
