KELAIWEI team designed dedicated 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, setting multi-section temperature zone, including the decomposition temperature zone of catalyst precursor and the growth temperature zone of carbon nanotubes, linear high-crystallization carbon nanotubes with different diameters and lengths are produced by adjusting the concentration of catalyst and the temperature of each temperature zone in the synthesis furnace.
KELAIWEI is a high-tech enterprise of carbon nanomaterials. Since the establishment of KELAIWEI, relying on the technical accumulation of over 20 years by Professor Sun Xiaogang's expert team of Nanchang University, KELAIWEI has actively explored the nanomaterials market at home and abroad. In 2008, Professor Sun's team has successfully synthesized whisker-like carbon nanotubes, in 2013, our company has achieved an annual production capacity of 30 tons, and now we have invested 0.45 billion to build a project of 300 tons of whisker carbon nanotube powder.
KELAIWEI nano-carbon material is a large-scale manufacturing enterprise focusing on the research and development of high-end nano-material technology, industrial production, domestic and foreign trade sales and high-end nano-material technology services. Henan KELAIWEI Nano Carbon Material Co., Ltd. cooperates with domestic scientific research institutions in colleges and universities to establish a capable technical research team, providing strong technical support for the product quality and technological innovation of our company.
With the resumption of production and resumption of work in all walks of life in our country after March, if the 2020 international heat conduction and heat dissipation materials and equipment exhibition held in Shenzhen city, Guangdong province is held as scheduled, our company will send product technicians to actively participate in it, we will launch new products of our company at that time. We sincerely look forward to meeting, talking, meeting and intersecting with you in the KELAIWEI exhibition area of Shenzhen Convention and Exhibition Center on August 27th, 2020.
Human beings' pursuit of high-end materials never stops. Carbon nanotubes are one of the artificial high-end materials. The diameter of carbon nanotubes is very small, and their conductivity is more than 10% better than that of carbon black. At the same time, their strength can reach more than 100 times of the strength of steel. Therefore, carbon nanotubes are widely used for high conductivity, high strength and other demanding precision product manufacturing fields. The chief engineer of Henan KELAIWEI Nano Carbon Material Co., Ltd has developed and studied the application of carbon nanotubes for more than 20 years, and has accomplished a lot in the technical field of carbon nanotubes.
How to make carbon nanotubes by chemical vapor deposition for mixed crystals of carbon? Carbon nanotube materials are widely used and have strong properties, but the output is very low and the manufacturing process is complex. Therefore, scientists have continuously improved the manufacturing method. Chemical vapor deposition is used to produce carbon nanotubes, its production efficiency is still relatively high chemical vapor deposition method cleans the gas containing carbon through catalyst to obtain carbon nanotubes, carbon mixed crystals.
Generally, the purification process of carbon nanotube products is pickling or low-temperature purification below ℃. A large amount of waste acid and waste water are generated during pickling and purification. The Environmental Protection pressure is high during the process of treatment, whisker carbon nanotubes adopt ultra-high temperature purification process, the purification temperature is generally 2800-3000 ℃, the purification temperature is higher, the metal impurities are lower, there is no waste acid and waste water, the purification process is more environmentally friendly, the products adopting this purification process have better performance, better thermal conductivity and conductivity.
