KELAIWEI Group has researched and developed for more than 20 years in order to realize the high performance and high stability of domestic carbon nanotube materials. From the establishment of the project by R & D personnel 20 years ago to 2020, all the staff of KELAIWEI group have spent 0.45 billion yuan to construct the project of processing and producing 300 tons of whisker carbon nanotube powder annually through hard work. Our new products and technologies will also be presented to our partners at the International Exhibition of heat conduction and heat dissipation materials and equipment held in Shenzhen Convention and Exhibition Center.
Is carbon nanotubes a stealth material? Carbon nanotubes are excellent stealth materials. Carbon nanotubes have stealth effect on infrared. The wavelength of infrared and radar wave is much larger than that of nanoparticles, and the specific surface area of nanoparticles material is 3 orders of magnitude or 4 orders of magnitude of conventional coarse powder, thus nanoparticles material can easily reduce the reflectivity of wave. It also has excellent stealth ability to electromagnetic waves.
Since its establishment, Henan KELAIWEI nano-Carbon Material Co., Ltd. has been insisting on promoting the development of China's high-end nano-material industry, breaking the foreign monopoly on high-end nano-material technology as its own duty, and insisting on independent research and development and innovation, take technical force to serve the motherland and technological progress to obtain enterprise benefits as the driving force for development. Relying on complete intellectual property rights, we have completed product research and development, process design and mass production, and continuously supply high-end technical products to customers in batches.
The ash content in the coarse powder of carbon nanotubes and the whisker carbon nanotubes have always been a difficult problem in production: impurities. The higher the purity of whisker carbon nanotubes, the more advanced it is. At present, there is no whisker carbon nanotubes with 100% purity. At present, the whisker carbon nanotubes produced in the market all contain certain metal impurities. However, KELAIWEI company has been able to control the content of metal impurities in whisker carbon nanotubes within 50ppm.
Adding carbon nanotubes can improve the wear resistance and thermal conductivity of automobile tires by 30%, and greatly improve the service life of tires. At present, only Michelin company abroad has the production technology of carbon nanotubes enhanced tires, KELAIWEI, qingdao University of Science and Technology and Qingdao Linglong Tire three parties cooperate to jointly develop carbon nanotubes reinforced tire adding 1-3% whisker carbon nanotubes can improve the wear resistance of tires by 30% and the thermal conductivity by 20%, greatly improve the comprehensive performance and service life of tires.
A far-infrared insole manufacturing enterprise in Guangdong has a small scale and doesn't have much research and development of new products. It has long relied on a single product of far-infrared insole to survive, and has accumulated a large number of far-infrared insole customers. In order to improve the competitiveness of its products, we started to improve the material performance of the products, and the far infrared paper of our KELAIWEI company just met the current demand of customers, and finally it saved other raw materials, the ash content in carbon nanotube coarse powder.
Far infrared paper (FIRPs) with excellent performance developed by Henan KELAIWEI Nano Carbon Material Co., Ltd. is being purchased by manufacturers at home and abroad. Using far infrared paper in the field of heating and keeping warm can improve the product's keeping warm performance. It is widely used in the field of food heating products manufacturing and automobile power supply boiling water equipment, and is also used as far infrared equipment manufacturing by health therapy equipment manufacturers, it has become an indispensable material in many manufacturers' production.
