Technical advantages, quality advantages, integrity advantages, and the service cooperation concept of achieving win-win results by making profits with Justice help KELAIWEI nanomaterials move to all corners of the world. In the past 20 years, KELAIWEI nanomaterials have experienced the siege and interception of foreign technologies and insisted on independent research and development. Up to now, KELAIWEI has applied for more than 100 technology patents and sold its products to more than 60 countries around the world. KELAIWEI company is looking forward to working with you to develop the market of nanomaterials.
Since its establishment in 2018, Henan KELAIWEI Nano Carbon Material Co., Ltd has paid great attention to the development of high-end nano material technology and the formation of talent team. In order to realize the scientific research goal of clevere company, our company has maintained deep cooperation with many domestic universities and scientific research institutions. For example, the team of Professor Sun Xiaogang from Nanchang University, Donghua University, Zhengzhou University of light industry and other universities continuously input product technology and talent strength for our company.
5G commercial business is developing in full swing, and the importance of 5G key material industry is self-evident, then who has mastered the key technology and has 5G key material supply terminal, will grasp the "sharp tool" in the development of 5G commercial equipment ". KELAIWEI group is looking forward to presenting our products and technologies in Shenzhen international 5G key material industry exhibition 2020, and communicating with you about the cutting-edge technologies of the industry.
Carbon nanotube material is an important material in the high-end manufacturing field, but due to different manufacturing methods, the purity of the obtained carbon nanotubes is also uneven, and the performance of high purity carbon nanotubes is more excellent. At present, researchers of nanomaterials in the world are conducting in-depth research in order to obtain super-pure carbon nanotubes. Henan KELAIWEI Nano Carbon Material Co., Ltd. has made another breakthrough progress in the field of whisker carbon nanotubes.
Preparation of carbon nanotubes by hydrothermal method brief analysis put the acidic solution of sucrose (according to the ratio of 1 to 19, made by stirring in the solution of sucrose mixed with h2so4-4) into the reaction kettle, in 12 hours, after the reaction from high temperature of 180 degrees, it is cooled to the indoor temperature. After centrifugal separation, ionized water is removed. After washing and drying, carbon nanotubes of 1 nanometer to 2 nanometer length can be obtained, carbon coated silver nanoparticles can shield battery waves.
Carbon-coated silver nanoparticles can shield battery waves, and 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.
