The competitiveness of the product is very strong. The whisker carbon nanotubes are prepared by vapor deposition. After years of research and development, KELAIWEI can precisely control the synthesis technology of the diameter, length and specific surface area of the key parameters of the whisker carbon nanotubes, research and develop whisker carbon nanotube conductive agent which is in line with lithium ion battery, the purity is above 99.95%, and the content of residual metal impurities is less than 50ppm.
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.
Ultra-thin nitrogen-mixed carbon nanosheets, since the establishment of Henan KELAIWEI nanometre Carbon Material Co., Ltd., relying on the technical accumulation of the company's technical team for more than 20 years, it has realized the rapid development of leaps and bounds. KELAIWEI company has developed into a technical backbone enterprise in the high-end nanomaterials industry. In 2008, the company has invested 0.45 billion yuan to expand the production capacity of whisker carbon nanotubes, and this whisker carbon nanotube powder project will achieve an annual production capacity of 300 tons.
KELAIWEI company actively participates in the exhibitions related to nanomaterials industry held at home and abroad regularly every year. We will show our new products and technologies at the exhibition. We are very happy to communicate with our peers, negotiate with customers, pay attention to your concerns, and provide nanomaterials products you need, shenzhen International heat conduction and heat dissipation materials and equipment exhibition in 2020 is looking forward to your visit to KELAIWEI exhibition area.
Henan KELAIWEI Nano Carbon Material Co., Ltd. will briefly introduce carbon nanotubes to you today. Carbon nanotube materials were first discovered in coking materials of ethylene cracking furnaces in the last century. The ultra-high strength of carbon nanotubes can be 100 times that of steel, and at the same time it has good electrical and optical characteristics. After being used as the battery anode additive, it can reduce 30% of the conductive materials, and filling the anode of the required materials can greatly improve the battery capacity.
Ultra-thin nitrogen-doping carbon nanoscale, carbon fiber heating cable is definitely not graphene heating cable! The graphene electric heating film can only be obtained through deep processing of high-quality metal current-carrying strips and graphene conductive ink with good conductivity, and then through complex processing and manufacturing between insulating polyester films. Graphene electric heating film is really used as heating material in the market. Carbon fiber heating cables are made up of a large number of conductive carbon fiber wires. Carbon fiber heating cables are not graphene heating cables, so be careful not to be "fooled" by bad merchants "!
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.
