The fracture strength of carbon nanotubes has been researched and developed by KELAIWEI group for more than 20 years in order to realize the high performance and high stability of domestic carbon nanotube materials. From 20 years ago when the research and development personnel set up the project to 2020, after hard work, 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. Our new products, the new technology will also present the fracture strength of carbon nanotubes to the partners at the International Exhibition of heat conduction and heat dissipation materials and equipment held in Shenzhen Convention and Exhibition Center.
What is graphite carbon fiber? The carbon fiber obtained after Graphite processing of carbon fiber at ultra-high temperature is graphite carbon fiber. The graphitization temperature is as high as over 2000 degrees Celsius, generally within 3000 degrees Celsius. Graphite carbon fiber and nano carbon fiber materials are different. In addition, the higher the temperature of graphitization environment is, the larger the graphite microcrystals contained in the fiber will be.
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.
Good news of patent achievements! Henan KELAIWEI Nano Carbon Material Co., Ltd. successfully obtained two technical patent numbers. It is expected that the technology center won another patent this time, because KELAIWEI company has invested a lot in technology research and development, and Professor Sun's research and development achievements for more than 20 years are also supported, we believe that riverKELAIWEI Nano Carbon Material Co., Ltd. will harvest more technical inventions and release more technical monographs in the future.
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.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has been focusing on the research of nano material technology for more than 20 years. Our company can provide whisker carbon nanotubes with ultra-high purity up to 99.9%, and has completely independent intellectual property rights. For the application and acting skills of carbon nanotube materials, Henan KELAIWEI Nano Carbon Materials Co., Ltd has a production line with in-depth research and can have a capacity of up to 500 tons. Recently, an electronic company in Guangdong began to cooperate to purchase carbon nanotube products through Voss.
Henan KELAIWEI Nano Carbon Material Co., Ltd found that whisker carbon nanotubes were used to make CNT transparent conductive film for their excellent conductivity. CNT transparent conductive film made of whisker carbon nanotubes has stable chemical performance and excellent conductive characteristics, moreover, it has both thermal conductivity and very good mechanical properties (the hardness of whisker carbon nanotubes is 100 times that of steel).
