Dr. Li Yingyi, associate professor, presided over and participated in the national science and technology support plan, National Natural Science Foundation, Provincial Natural Science Foundation and provincial education department fund, and won the third prize of Jiangxi natural science in 2011 (the third prize). Research Fields: synthesis and application of carbon nanotubes, nano new energy materials, rare earth functional materials, LED optical conversion materials, lithium ion batteries, nano-reinforced composite materials, etc. Currently, he is the project team leader in the R & D team of KELAIWEI, have rich development experience.
The nanomaterials developed and manufactured by the expert team led by Professor Sun Xiaogang of KELAIWEI company have been sold to more than 60 countries and regions around the world. Currently, the processing and manufacturing of high-performance lithium batteries, the application of wearable equipment materials, the development of environmental protection and new energy, special material preparation fields and so on will be applied to high-end nanomaterials KELAIWEI company is willing to cooperate sincerely with people with lofty ideals all over the world to jointly explore relevant markets and carbon crystal heating pads.
KELAIWEI nano carbon material company has established Henan KELAIWEI Nano Carbon Material Co., Ltd. and Jiangxi KELAIWEI Nano Carbon Material Co., Ltd. KELAIWEI company continues to develop, expand investment and expand the scale of production and operation. KELAIWEI company invested 0.45 billion yuan to invest 13,000 square meters of factory area in Henan, and maintained deep cooperation with experts at home and abroad. Our company attaches great importance to the research and development and innovation of advanced technologies of nanomaterials.
Carbon crystal heating pad, the KELAIWEI company's spring fun sports meeting, after a fast-paced competition, is brilliant, and finally decides the winning team of each project. The first manufacturing team of Henan KELAIWEI Nano Carbon Material Co., Ltd. won the first prize of "crossing the river by touching bricks", the administrative team of KELAIWEI won the first prize of "United heart competition", and the quality control team defended the champion of "crossing the river with one leg" again. KELAIWEI company is always concerned about the health and entertainment activities of its employees.
Silicon-based devices are large-scale commercial electronic devices, but the pursuit of science is endless, and the pursuit of manufacturing materials with stronger performance and smaller size is always pursued. However, carbon nanotubes have super high conductivity, whose strength is 100 times higher than that of steel, and their thermal conductivity is very strong, which is 10% better than that of carbon black, therefore, carbon nanotubes will become important materials to replace silicon-based devices.
What are the manufacturing methods of carbon nanotubes? Since the discovery of carbon nanotubes, the research on carbon nanotubes has never stopped. Carbon nanotubes have complex and excellent properties. It is both conductive and conductive, very thin but very hard, which is comparable to a hundred times of the hardness of steel. Carbon nanotubes are widely used, so various preparation methods have also been invented. Common production methods include arc method, catalytic thermal decomposition method, hydrothermal method and chemical vapor deposition method, etc.
The far infrared paper made by using ultra-high purity whisker carbon nanotubes through papermaking process has a emission wavelength of 2-20 μm after being electrified, which is called "Light of Life" in medicine. The human body accepts far infrared ray, which can promote the metabolism of human body, it improves the circulation of human body, has the functions of relaxing muscles and promoting blood circulation, and improves the immunity of human body. The far infrared emission paper has good flame retardant characteristics. The far infrared emission paper has passed the ROHS certification of European Union, and is non-toxic, green and environmentally friendly new functional materials.
