The production system of whisker carbon nanotubes is fully automatic from feeding to product packaging. The growth time of carbon nanotubes is reduced from several hours to several seconds, which is much lower than the production time of traditional process for several hours, the production efficiency and cost have been greatly improved. The self-developed central control system monitors the parameters of the production process in real time, reduces the instability caused by human beings to the products, and the stability of the equipment is good, the product has very good consistency and stability, and this process is a major breakthrough in carbon nanotube synthesis technology.
Advantages and disadvantages of Shanghai carbon crystal heater, founded in June, 2018, Henan KELAIWEI Nano Carbon Material Co., Ltd. is mainly engaged in the research and development and manufacture of whisker carbon nanotubes, with an annual output of 30 tons of whisker carbon nano tube powder equipment, 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.
The technical team of Henan KELAIWEI Nano Carbon Material Co., Ltd. is one of the early domestic enterprises specializing in the technical research and development of high-end nano materials and manufacturing of industrial mass production equipment. Since its development, the technical team of KELAIWEI company, which has gone through more than 20 years, has successively applied for 9 national patents, and 2 monographs have been published. Our products have broken some technical monopolies of foreign counterparts, and went abroad and sold it abroad.
Traditional conductive agent products can no longer meet the manufacturing requirements of new high-end lithium batteries. KELAIWEI company is willing to help you develop the high-end lithium battery conductive agent market. The new type of conductive agent products researched and developed by KELAIWEI company will be presented in the exhibition area of KELAIWEI company in "2020 International Exhibition of heat conducting and heat dissipation materials and equipment in Shenzhen Convention and Exhibition Center" on August 27th, 2020.
The three-day international exhibition of heat conduction and heat dissipation materials and equipment starting from August 27th, 2020 will be held in Shenzhen Convention and Exhibition Center, Guangdong province. Due to special circumstances-the impact of the new Crown epidemic this year, if this exhibition can be held as scheduled, Henan KELAIWEI Nano Carbon Material Co., Ltd. will send our product technical backbones to participate actively, at that time, our major products will be on display.
How is graphene thermal film obtained? Put copper metal current-carrying strip, silver strip and graphene conductive layer between two layers of polyester film, and use science and technology to obtain graphene heating film after a series of processing. Henan KELAIWEI Nano Carbon Material Co., Ltd. found that in recent years, there have been some new types of floor heating in Jiangsu and Zhejiang areas, among which there are cases of using graphene heating film to make electric floor heating materials, which are quite popular in the market.
Advantages and disadvantages of Shanghai carbon crystal heater. 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.
