Nano-carbon heating film, KELAIWEI nano-Carbon Material Co., Ltd. is mainly engaged in the research and development, production and sales of carbon nanotubes. It always puts the application of carbon nanotubes in the main direction of research and development, and guides the research and development team according to the market demand, constantly optimize production process and technology. At present, the equipment has broken the technological gap in China and has completely independent intellectual property rights. This technology has applied for a total of 106 related invention patents and 2 international PCT patents, which belongs to the backbone of the country and the international advanced level.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has been insisting on technology since its establishment. After more than 20 years of technological development, our company has become a high-end manufacturing technology enterprise in the carbon nanotube material industry. With the continuous increase of the market demand for carbon nanotube materials, in order to meet the market demand, the supply of high-quality KELAIWEI nanomaterials products, KELAIWEI company has invested in the construction of the whisker carbon nanotube powder project whose output value reaches 300 tons per year.
Henan KELAIWEI nano carbon material company, relying on its profound technical deposits of high-end nano materials, makes the enterprise go to the fast lane of rapid development. The production line of several nanomaterials built by KELAIWEI company with 0.45 billion yuan the year before last will increase the annual production capacity of 300 tons of whisker-like carbon nanotube powder. With advanced technology and 6S lean management, KELAIWEI company creates word-of-mouth products for customers.
Traditional conductive agent products can no longer meet the manufacturing requirements of new high-end lithium batteries. KELAIWEI company is willing to help you develop the high-end lithium battery conductive agent market. The new type of conductive agent products researched and developed by KELAIWEI company will be presented in the exhibition area of KELAIWEI company in "2020 International Exhibition of heat conducting and heat dissipation materials and equipment in Shenzhen Convention and Exhibition Center" on August 27th, 2020.
The less the amount of conductive agent added, the material with super conductive property has always been pursued by scientists, and carbon nanotubes is such a perfect material. Tens of thousands of hair filaments are equal to the thickness of a carbon nanotube side by side, the application of carbon nanotubes is a conductive agent, which performs well in the manufacturing and application field of high-end lithium batteries. Only a trace of carbon nanotubes conductive agent is needed, and it can play a super conductive and thermal conductivity, which is far superior to carbon black conductive agent and nano carbon heating film.
Synthesis of carbon nanotubes by hydrothermal method. Put the acidic solution of sucrose (according to the ratio of 1 to 19, and mix it with h2so4-sucrose solution) into the reaction kettle, and cool it to the indoor temperature after the reaction of 180 degrees high temperature within 12 hours, after centrifugal separation, ionized water is removed, and after washing and drying, carbon nanotubes of 1 nanometer to 2 nanometer length can be obtained.
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 materials of products with high graphitization degree have been greatly improved.
