Nano-carbon materials and their progress, KELAIWEI team designed special linear high-crystallization carbon nanotubes into a furnace, the synthetic furnace has been improved for more than 4 generations, adopting unique structure design, new heating element, new furnace structure design, set multiple temperature zones, including decomposition temperature zone of catalyst precursor and growth temperature zone of carbon nanotubes, and produce linear high-crystalline carbon nanotubes with different diameters and lengths by adjusting the concentration of catalyst and the temperature of each temperature zone in the synthesis furnace.
KELAIWEI company will continue to invest in top expert teams and research and development funds to devote itself to the research and development of nanomaterials technology and equipment, providing you with nanomaterials products with high stability and high technical standards. In the past 20 years, the R & D team of KELAIWEI company-the expert team led by Professor Sun Xiaogang of Nanchang University has independently researched and developed the production and preparation technology of whisker carbon nanotubes. Our company has invested 0.45 billion in the construction of whisker carbon nanotubes powder project, today's KELAIWEI products have been exported to 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.
The meeting of the group improvement office was held through the video of "DingTalk. Director Yuan Hongwei of the improvement office of the group arranges five key tasks to carry out questionnaires with the theme of lean improvement, investigate the current situation of the enterprise, master the voices of the employees of the enterprise, and do the next lean work well. Pay special attention to the appraisal work of excellent improvement specialists, actively participate in the second lean tools competition, and implement the 5S silver medal certification training plan.
In the field of high-end lithium ion battery manufacturing, a new material is being rapidly applied, namely carbon nanotubes. Compared with the traditional electric black, the conductivity of carbon nanotubes is one tenth higher than that of the latter, and its weight is very light. It is enough to be added and used in a small amount. Compared with the traditional materials, the use of conductive materials can be reduced by 30%. Therefore, KELAIWEI company expects that the market prospect of carbon nanotubes will be bright and the market demand for carbon nanotubes will rise rapidly.
Is carbon nanotubes a stealth material? Carbon nanotubes is an excellent stealth material carbon nanotubes have stealth effect on infrared infrared the wavelength of infrared and radar wave is much larger than that of nanoparticles, moreover, the specific surface area of nano-particle material is 3 orders of magnitude or 4 orders of magnitude of conventional coarse powder, thus the nano-particle material can easily reduce the reflectivity of waves and also has excellent stealth ability to electromagnetic waves, nanometer carbon materials and their progress.
Metal Impurities will affect the self-discharge of the battery. Metal impurities will spontaneously react with the original battery inside the battery, causing self-discharge. At the same time, the higher the metal impurities are, the worse the safety performance of the product is, metal Impurities will pierce the membrane of lithium ion battery and cause short circuit of the battery. Power battery has extremely strict requirements on this index. Generally, it is required to be controlled below 100ppm, while domestic carbon nanotube metal impurities are generally controlled above 200ppm, whisker carbon nanotubes can be controlled above 100ppm, and the product is better.
