Large-scale nano-carbon tubes, whisker carbon nanotubes research and development cycle is long, it is not easy to achieve a breakthrough in a short time, ordinary carbon nanotubes all use solid catalyst, the catalyst is deposited on the surface of the carrier material, carbon nanotubes are synthesized by introducing hydrocarbon gas after calcination and reduction. Compared with traditional carbon nanotubes, the process technology of whisker carbon nanotubes is more complicated. In the process of synthesizing whisker carbon nanotubes, improper regulation may lead to the growth of non-linear ordinary carbon nanotubes, the product has high requirements for process control.
KELAIWEI makes high-performance and stable carbon nanotubes. At the beginning of its establishment, KELAIWEI paid attention to maintaining technical advantages and maintained close cooperation with university research institutions and expert teams. Our company has deeply cooperated with Professor Sun Xiaogang's team and has applied for more than 100 invention patents, of which nine have obtained national authorized invention patents and two international PCT patents. Relying only on technical advantages, KELAIWEI's products have been completed from Henan and Jiangxi to more than 60 countries in the world.
KELAIWEI company's brand is "famous" in the industry relying on excellent technology and efficient and strict management ". Our company has more than 20 years of technical accumulation, and continuously maintains cooperation with domestic university research and development experts. The company is managed by international management standards and has passed IATF16949 and ISO9001 certification. Our company also has advanced production technology and equipment researched and developed independently, and is in an important position in the field of high-end nanomaterials.
From August 27th to August 29th, 2020, the exhibition center in Shenzhen city, Guangdong province will welcome the international 5G key material industry exhibition summit. KELAIWEI group will participate in this grand meeting as promised. In 2020, the development of 5G commercial equipment at home and abroad will enter an important stage. The prospect of 5G key materials industry will be "bullish". KELAIWEI group has strong technical strength. Our company will certainly bring you surprises in this exhibition.
According to KELAIWEI Carbon Nano Carbon Materials Co., Ltd, a large international company in South Korea has decided to expand the production capacity of carbon nanotubes to meet the market demand of carbon nanotubes. At present, this large enterprise has an annual production capacity of 1200 tons of carbon nanotube materials. This investment will expand the production capacity of 500 tons of carbon nanotubes, thus further strengthening its competitiveness in the carbon nanotube industry.
What is nano carbon fiber? Carbon nanofibers are a new type of nanomaterials. Nanometer carbon fiber has rich characteristics: light mass low density, large aspect ratio (100 nm -500 nm), diameter 50 nm -200 nm, stable and strong electrical conductivity, etc, moreover, the production cost is much lower than that of carbon nanotube materials, which is easier to be manufactured in batches and has higher output.
The graphitization degree of large-scale carbon tube and whisker carbon nanotubes is high. Using X-ray diffraction, the graphitization degree of the product calculated by specific formula can reach more than 90%. In Raman spectrum detection, the D/G of the product is generally below 0.2, and the D/G ratio of ordinary carbon nanotubes is generally above 2. The size of D/G reflects the number of defects of the product. The larger the D/G is, the more defects of the product, the closer the whisker carbon nanotubes are to the ideal material, and the fewer defects of the product, the closer to the performance of the ideal material.
