KELAIWEI has a professional research and development team. The team now has 3 deputy senior staff, 2 doctors and 7 postgraduates. The team members have rich experience in production, study and research, among them, the main person in charge of the team is Professor Sun Xiaogang from Nanchang University. Professor Sun Xiaogang has more than 20 years of research and development experience of carbon nanotubes, and is one of the earliest experts in the research of whisker carbon nanotubes in China, he is one of the earliest experts in industrialization of carbon nanotubes in China. He has rich research experience in the field of carbon nanotubes and summarizes nano-carbon materials.
KELAIWEI specializes in the preparation technology of nanomaterials for more than 20 years. In the past 20 years, Professor Sun Xiaogang's technical research and development team of Nanchang University has continuously output technical achievements. Now KELAIWEI company has helped enterprises in more than 60 countries around the world to solve the required nanomaterials products. The manufacturing equipment and technology of whisker carbon nanotubes researched and developed by our company by ourselves have the dominant advantage of technology at home and abroad. Our company has applied for 106 patents including 9 national authorized invention patents and 2 international PCT patents.
In 2018, Henan KELAIWEI Nano Carbon Material Co., Ltd. was successfully established in Dengfeng with a registered capital of 60 million RMB. Henan KELAIWEI has an independent factory area of 13,000 square meters, planning dozens of production lines. By virtue of the 6S lean management law, all functional departments of our company are guaranteed to work scientifically and orderly and innovate actively. As of March 2020, our company has applied for 60 patents.
In summary, production skills are very important, and safety skills and safety awareness are more important. No production can be performed without security guarantee. Henan KELAIWEI Nano Carbon Material Co., Ltd. regularly carries out staff safety production skills training. KELAIWEI company firmly believes that production safety training is responsible for employees, customer products, the company and the basic requirements of the enterprise's production safety responsibility.
Single-walled carbon nanotubes are high-purity carbon nanotube materials. Single-walled carbon nanotubes are very fine, and the fineness of tens of thousands put together is equivalent 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.
What is graphite carbon fiber? The carbon fiber obtained after Graphite processing of carbon fiber at ultra-high temperature is graphite carbon fiber. The graphitization temperature is as high as over 2000 degrees Celsius, generally within 3000 degrees Celsius. Graphite carbon fiber and nano carbon fiber materials are different. In addition, the higher the temperature of graphitization environment is, the larger the graphite microcrystals contained in the fiber will be.
Due to the adoption of pickling or low-temperature purification process, the graphitization of ordinary carbon nanotubes is generally below 30%, and the whisker carbon nanotubes are purified at a high temperature of 300℃, and carbon atoms are rearranged at high temperature, with the passage of heat preservation time, the arrangement of carbon atoms is more and more regular, thus the performance in all aspects is better. Generally, the graphitization degree of whisker carbon nanotubes purified at high temperature can be above 80%, the thermal conductivity and conductivity of materials of products with high graphitization degree have been greatly improved.
