There are two professional works on carbon nanotubes and more than 60 technical patents (including 9 national authorized patents and 2 international PCT patents)...... This is the fruit of technology patent continuously picked by Henan KELAIWEI Nano Carbon Material Co., Ltd. All these achievements benefited from the hard research of the technical center staff led by Professor Sun Xiaogang, the chief engineer of KELAIWEI nano carbon material company. KELAIWEI Technology Center will continue to create technological glory.
The purity of carbon nanotubes reflects the technological level of the product. The higher the purity, the greater the technological difficulty. The metal impurity content of ordinary carbon nanotubes is generally above 200ppm, through the high temperature purification process of 3000 ℃, the whisker carbon nanotubes are put into the furnace by using a specific crucible, and the purification time is more than 10 hours. The metal impurities inside the carbon nanotubes can be completely vaporized, the content of metal impurities can be controlled within 100ppm, the purity level is extremely high, and the use of lithium ion batteries is more assured.
The long conjugated chain segment of single chiral carbon nanotubes was successfully synthesized by our research group of Professor Du Pingwu of China University of Science and Technology. It is reported that the introduction of long conjugated chain synthesis of single chiral carbon nanotubes has been published in the form of a cover article in The Journal of the American Chemical Society. This achievement is of great significance and will provide conjugated polymer templates for the manufacture of ultra-pure single-walled carbon nanotubes. At the same time, it will also have great reference significance for the preparation of single chiral carbon nanotubes by solution method.
Henan KELAIWEI Nano Carbon Material Co., Ltd. was founded in June, 2018. It is mainly engaged in the research and development and manufacture of whisker carbon nanotubes, and has equipment with annual output of 30 tons of whisker carbon nano tube powder, we have invested 0.45 billion yuan to build the project of whisker carbon nano-tube powder with annual production capacity of 300 tons. This project is carried out in two phases, and the production capacity of each phase is designed to be 150 tons/year, KELAIWEI is committed to promoting the development of the domestic whisker carbon nanotubes industry, a carbon crystal floor heating factory.
A manufacturer of far infrared electric heating room in Henan has recently developed a new product. In order to reduce the use of heat conduction materials in order to save space, adding other parts, it is urgent to use far infrared paper to replace some materials, however, the company has strict requirements on the working temperature of the far infrared paper, requiring that the far infrared paper still has super stability within 120 degrees, and the suppliers in the provinces nearby the company are not suitable, finally, we chose our products (the working temperature is less than 300 degrees).
"Integrity, enthusiasm, profession, profession and efficiency" is the work label of the service staff of Henan KELAIWEI Nano Carbon Material Co., Ltd. By learning and applying the 6S lean management law, KELAIWEI company makes the staff of our service center realize the importance of adhering to the attitude of "serving customers wholeheartedly. So far, our service center personnel have not received any complaints from customers.
For carbon crystal floor heating manufacturers, the common transparent conductive films include metal film series Transparent conductive film, oxide film series Transparent conductive film, polymer film series Transparent conductive film, composite film series Transparent conductive film and so on. However, the transparent conductive film is highly transparent in the range of visible light wavelength and has ultra-high conductivity at the same time. Therefore, the transparent conductive film is widely used in the manufacture of modern high-end equipment, carbon nanotubes are one of the indispensable and important materials for the manufacture of Transparent Conductive Films.
Carbon crystal floor heating manufacturer, how does chemical vapor deposition method produce carbon nanotubes? Carbon nanotube materials are widely used and have strong properties, but their production is very low and the manufacturing process is complex. Therefore, scientists have continuously improved the manufacturing methods. Chemical vapor deposition method is used to produce carbon nanotubes, and its production efficiency is still relatively high. By chemical vapor deposition, carbon-containing gases are cracked by catalysts to obtain carbon nanotubes.
Henan KELAIWEI Nano Carbon Material Co., Ltd. is a large-scale production enterprise of whisker carbon nanotubes, which is jointly invested and established by Zhengzhou Dengcao Group Company and Jiangxi KELAIWEI Nano Carbon Material Co., Ltd. The company adopts the self-developed technology and equipment of the world's backbone whisker carbon nanotubes production, and builds a production line with an annual output of 300 tons of whisker carbon nanotubes. The first phase of the project with an annual output of 150 tons of high-performance whisker carbon nanotubes was put into production in September 2019, with an investment of more than 0.1 billion yuan.
