The centrifugal speed of nanometre carbon balls, KELAIWEI's back to Henan denggou group, the predecessor of Zhengzhou Dengcao Group Co., Ltd. was the Dengcao coal mine established in 1973. After years of development, Dengcao group has gradually covered many fields such as coal, finance, education, real estate and so on, and has accumulated a lot of shopping experience. With the strong support of the group company, KELAIWEI actively promotes technology and product innovation, increases investment and strives to move towards high-tech enterprises.
KELAIWEI cooperates with Professor Sun Xiaogang of Nanchang University. Relying on the advanced technology accumulated by Professor Sun Xiaogang's expert team for more than 20 years, he has applied for a total of more than 100 patented technologies and 9 national authorized invention patents. Our company relies on advanced technology to independently research and develop production equipment, build production base and train production technicians, so as to realize the full-automatic chemical industry to produce the batch production of whisker-like carbon nanotubes.
Henan KELAIWEI Nano Carbon Material Co., Ltd. is one of the well-known enterprises in the high-end nano materials industry. KELAIWEI owns 2 international PCT patents, 9 national patents, more than 40 industry papers and 2 monograph on carbon nanotube industry...... In the field of high-end nanomaterials, the leaders of KELAIWEI company make decisions to continuously invest heavily in research and development. Our company will continue to tackle key problems, continue to break the technology monopoly of foreign industries, and make contributions to the development of nanomaterials technology in our motherland.
In special times, we should strive more. In April, our company held a symposium to consolidate the promotion year. The sales directors and advanced sales representatives of each center communicated and learned with each other, and everyone spoke freely, analyzed the current product sales situation, problems and solutions, and the chairman of the board fully affirmed everyone's work achievements, at the same time, we also encourage everyone to learn from first-class enterprises such as Huawei and Alibaba, and do a good job in our annual sales in 2020.
In the guidance of new material industry development planning, China proposes to give priority to the development of advanced new functional materials, composite materials with high performance, etc. Thanks to policy and market stimulation, research on nano-carbon materials has developed rapidly. Nanometer carbon materials have broad development and application prospects in the fields of catalysts, new high-performance composite materials and hydrogen storage. Henan KELAIWEI Nano Carbon Material Co., Ltd. responded to the national call and invested 0.45 billion yuan to expand the production capacity of whisker carbon nanotubes.
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 the centrifugal speed of carbon nanotubes and nanometer carbon balls.
The specific surface area of whisker carbon nanotubes is generally 13~50 m2/g, and that of ordinary carbon nanotubes is above 200 m2/g. The larger the specific surface area is, the worse the dispersion performance of the product is, the agglomeration of conductive agents is more likely to occur. In lithium ion batteries, the larger the specific surface area is, the greater the gas production of lithium ion batteries will be in the long-term cycle process, smaller specific surface area is conducive to improving the cycle performance of lithium ion batteries and reducing the gas production of batteries in the later cycle process.
