KELAIWEI has established a professional development team aiming at the far infrared paper industry. After preliminary testing and certification, it has established long-term cooperative relations with many units, including Ningde times, BYD, micro Macro power and other power battery enterprises have established a professional development laboratory internally. The laboratory has professional manufacturing and testing equipment for far infrared transmitting paper, which ensures the research and development of transmitting paper, at the same time, different heating paper products can be customized according to customer's needs.
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.
KELAIWEI company invested 0.45 billion yuan to build dozens of production lines in Henan production base, owning a factory area of 15000 square meters, and designed the production line of whisker carbon nano-tube powder with an annual output of 500 tons, the capacity of the first and second phase projects is 150 tons/year. The company mainly researches and develops whisker nanometer synthesis process and equipment, carbon nanometer powder, carbon nanometer paste, mixed paste and other products.
The ground carbon crystal wall is warm, and the commercial business of 5G is developing in full swing. The importance of 5G key material industry is self-evident, then who has mastered the key technology and owned the supply end of 5G key material, it 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.
Anode conductive additives are needed in the manufacture of high-end lithium ion battery products to increase battery performance. Nowadays, the commonly used carbon black materials have affected the manufacture of lithium batteries with higher performance. At present, a new material carbon nanotubes has gradually been paid more and more attention by battery manufacturers because of its better conductivity and thermal conductivity, and it can save more than 30% of conductive materials, and put into applied research.
What are the main differences between carbon nanotubes and carbon nanofibers? Henan KELAIWEI Nano Carbon Material Co., Ltd. has published two monographs on carbon nanotubes and applied for more than 60 patents. The purity of the prepared whisker carbon nanotubes has reached 99.99%. Carbon nanotubes are carbon materials with hexagonal connection structure, while carbon nanofibers are wire-mounted materials. Fibers with a diameter of less than 1000 nanometers are all nanofibers.
In the ideal situation, carbon nanotubes belong to SP2 hybridization. Because & pi; The movement of electrons produces electrical conductivity, SP3 and SP hybridization is introduced at the bending place of carbon nanotubes, which affects the electrical conductivity of the product, the whisker carbon nanotubes belong to linear structure, and the product has few structural defects. The defective SP3 and SP are hybrid, and the conductivity of carbon nanotubes can be brought into play to a greater extent, and the conductivity of the product is better, when used in composite materials, the electrical conductivity of the materials can be significantly improved, and the ground carbon crystal wall is warm.
