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.
Nanometer carbon tubes are stable at normal temperature. Since its establishment, our company has been focusing on developing into a leader in the high-end carbon nanomaterials industry and devoting itself to the research on advanced technologies of carbon nanomaterials. As of May 2020, our company has applied for 60 invention patents, published more than 40 professional papers in the industry, published two monograph on carbon nanotubes, obtained 9 national authorized invention patents, it has obtained 2 international PCT patents and successfully walked out of the research and development path of a technology company combining production, teaching and research, breaking the foreign monopoly and selling its products all over the world.
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.
In special times, we should strive more. In April, our company held a symposium to consolidate the promotion year. The sales directors and advanced sales representatives of each center communicated and learned with each other, and everyone spoke freely, analyzed the current product sales situation, problems and solutions, and the chairman of the board fully affirmed everyone's work achievements, at the same time, we also encourage everyone to learn from first-class enterprises such as Huawei and Alibaba, and do a good job in our annual sales in 2020.
For lithium battery manufacturing enterprises, conductive agent products are very important. Henan KELAIWEI Nano Carbon Material Co., Ltd. observed that at present, the traditional conductive agent products are mostly conductive carbon black or nano carbon fiber, etc. In recent years, a new material has emerged: carbon nanotubes. Compared with the traditional conductive carbon black, its conductivity is improved by more than 10%. KELAIWEI company is committed to the research of carbon nanomaterials and looks forward to cooperating with you.
A brief introduction to the heating principle of graphene electrothermal film. First of all, graphene electrothermal film is a new material for processing and synthesis, which mainly passes through metal-carrying strips (common copper metal) between two layers of insulating polyester film. And graphene conductive ink with excellent conductivity is produced after hot pressing. Different from carbon fiber cables using irregular motion friction between atoms to make heating, graphene electric heating film generates heat by continuously releasing heat energy after carbon molecules that produce Brownian motion collide with each other.
Due to the adoption of pickling or low-temperature purification process, the graphitization of ordinary carbon nanotubes is generally below 30%, and the whisker carbon nanotubes are purified at a high temperature of 300℃, and carbon atoms are rearranged at high temperature, with the passage of heat preservation time, the arrangement of carbon atoms is more and more regular, thus the performance in all aspects is better. Generally, the graphitization degree of whisker carbon nanotubes purified at high temperature can be above 80%, the thermal conductivity and conductivity of the materials of products with high graphitization degree are greatly improved, and the carbon nanoparticles are stable at normal temperature.
