KELAIWEI company has invested 0.55 billion yuan to carry out deep cooperation with the research and development team led by Professor Sun Xiaogang of Nanchang University in China for a long time. And invested 0.45 billion yuan successively in Henan to build the first phase of whisker carbon nano-tube powder project and the second phase of whisker carbon nano-tube powder project, which made the production capacity of whisker carbon nano-tube powder of Henan KELAIWEI nano-Carbon Material Co., Ltd achieve qualitative improvement, up to 300 tons/year.
A brief introduction to the study of carbon nanotube catalyst carrier materials. Carbon nanotubes have very good photoelectric properties, and the specific surface area of carbon nanotubes is very large. Due to the large amount of active site eggs on the surface of carbon nanotubes, they are widely used as catalyst carriers. The academic research of carbon nanotube catalyst carrier pays special attention to the catalytic value of excellent electrical properties of carbon nanotubes, the influence of unique tubular structure of carbon nanotubes on catalysis, the influence of carbon nanotubes with extremely rich hydrogen storage characteristics on catalysis and other fields.
Acid oxidation of carbon nanotubes, Henan KELAIWEI Nano Carbon Material Co., Ltd. was successfully established in Dengfeng in 2018 with a registered capital of 60 million RMB. Henan KELAIWEI has an independent factory area of 13,000 square meters, planning dozens of production lines. By virtue of the 6S lean management law, all functional departments of our company are guaranteed to work scientifically and orderly and innovate actively. As of March 2020, our company has applied for 60 patents.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has invested a huge sum of money in technology research and development, and now it has fruitful results. The 106th technology invention patent has been taken in by KELAIWEI Technology Center. KELAIWEI company has a series of technological achievements, such as international PCT patent technology, national patent technology invention achievements, several industrial technical specialties and so on. In the future, the related technological patents KELAIWEI company will continue to obtain.
Electromagnetic shielding materials can be made by uniformly dispersing carbon nanotubes into polymer materials. Carbon nanotube shielding materials generally have broadband microwave absorption capacity, and at the same time have the characteristics of light weight and good electrical conductivity. Preliminary achievements have been made in the study of shielding materials of carbon nano-tube batteries. The shielding performance of carbon nano-tube electromagnetic shielding materials is close to that of metal copper foil and aluminum foil in high frequency band, and the shielding performance has been further improved, it is possible to replace metals for shielding materials in some fields.
The far infrared emission band of the paper produced by our company ranges from 2 nanometers to 20 nanometers, and the electrothermal conversion rate is as high as over 99.5%, which has obvious application effect in the field of thermal products. After our company provided samples for a honeycomb heat exchanger manufacturer in Beijing, the performance of the honeycomb heat exchanger was significantly improved, and the energy-saving effect was obvious after the trial of customers, especially the test of the product quality control department, which could save more than 25% of energy compared with the previous one.
Carbon nano-tube acid oxidation, Ba-based paper is also called carbon nano-tube paper because of the use of carbon nano-tube materials. The BA-based paper made by Henan KELAIWEI Nano Carbon Material Co., Ltd. has very good properties in terms of conductivity, thermal conductivity, strength and toughness. This is because carbon nanotubes are used. Carbon nanotubes are recognized as nanomaterials with strong mechanical properties, ultra-high conductivity, superconductivity and high strength.
