Professor Sun Xiaogang's long-term research on carbon nanotubes includes the synthesis, modification and filling of carbon nanotubes and the application of carbon nanotubes in the fields of electromagnetic shielding, wave absorption, lithium ion batteries and composite materials. Chairman and general manager of Jiangxi KELAIWEI Nano Carbon Material Co., Ltd. In 1999, it began to produce carbon nanotubes and provided them to the whole world. In 2000, it successfully developed a 5kg carbon nanotube device per day. In 2001, it established Nanchang Sun nanotechnology Co., Ltd. and served as the chairman and CEO, the company is one of the first several companies in the world to industrialize the production of carbon nanotubes (at that time there were only 7 companies in the world that could provide carbon nanotubes products), and the production of carbon nanotubes reached the ton level, users all over the world.
KELAIWEI company has been working hard for the high-end nanomaterials industry in the motherland for 20 years. It has developed domestic and overseas markets by virtue of its own technical development and high-end technical services, and has deep cooperation with enterprises in more than 60 countries. KELAIWEI company has built the project of whisker carbon nanotube powder with annual production capacity of 300 tons, and has obtained nine national authorized patents. KELAIWEI relies on its high-end nanomaterials research and development center to continuously provide customers with advanced nanomaterials and technical services.
Xinxiang carbon nanometer, KELAIWEI company invested 0.45 billion to build dozens of production lines in Henan production base with 15000 square meters of factory area, and designed the production line of whisker carbon nanometer powder to produce 500 tons per year, the capacity of the first and second phase projects is 150 tons/year. The company mainly researches and develops whisker nanometer synthesis process and equipment, carbon nanometer powder, carbon nanometer paste, mixed paste and other products.
KELAIWEI company firmly believes that safety is the highest welfare for enterprises and employees, and safety is an important prerequisite for creating high-end product value. The monthly safety inspection of KELAIWEI company is held irregularly. There is no fixed time and no fixed area. The company's office, warehouse, workshop and so on should be checked safely at any time, make employees keep working safely at all times. Henan KELAIWEI Nano Carbon Material Co., Ltd takes safe production as its own responsibility and strives to create value.
The application field of carbon nanotube materials is being accelerated. Because it has a conductivity of more than ten percent higher than that of traditional materials, its conductivity and thermal conductivity can be equivalent to that of copper and diamond. At present, it has been used by automobile manufacturers to manufacture automobile parts, battery manufacturers to manufacture high-end lithium batteries, and aviation industry to manufacture aircrafts...... Henan KELAIWEI Nano Carbon Material Co., Ltd. has increased the production of whisker carbon nanotubes to meet the market demand.
A brief analysis of the role of Xinxiang carbon nanometre and carbon nanotubes in the development of composite material manufacturing and Electrostatic spraying technology. Carbon nanotubes have excellent electrical and mechanical characteristics and can be used as additives for composite materials. For example, its conductive effect has been verified in the laboratory, indicating that carbon nanotubes have higher conductive effect than carbon powder, stainless steel wire and other materials. At the same time, carbon nanotubes can also be used in Electrostatic spraying process, saving procedures and making spraying effect better.
Due to its special structure, the thermal conductivity of the product can reach 3000w/(m · K) under ideal conditions, but ordinary carbon nanotubes will introduce a large number of defects in the production process, causing the bending of carbon nanotubes, the crystal structure of carbon nanotubes is damaged, and the thermal conductivity is affected. The whisker carbon nanotubes belong to linear structure, and the crystal structure of carbon nanotubes can be retained to the maximum extent, the thermal conductivity of the product can be brought into play to a greater extent and has a very broad space in the field of 5G heat dissipation.
