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.
How is carbon nanotubes made by chemical vapor deposition? Carbon nanotube materials are widely used and have strong properties, but their production is very low and the manufacturing process is complex. Therefore, scientists have continuously improved the manufacturing methods. Chemical vapor deposition method is used to produce carbon nanotubes, and its production efficiency is still relatively high. By chemical vapor deposition, carbon-containing gases are cracked by catalysts to obtain carbon nanotubes.
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.
KELAIWEI Nano Carbon Material Co., Ltd. invested 0.55 billion yuan in 2017 and 2018 to build production research and development centers: Jiangsu KELAIWEI production research and development center and Henan Dengfeng KELAIWEI production research and development center. KELAIWEI Nano Carbon Material Co., Ltd. has recently expanded the production of whisker carbon nano-tube powder in Henan's 13,000-square-meter production base, with an annual output of 300 tons.
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.
A lithium battery manufacturer in Guangdong put forward higher requirements for the purity of carbon nanotubes when researching and developing a new product-high-performance lithium battery product. At first, it was considered to be imported from abroad, but at last, it was found that, some foreign manufacturers asked too much, and later found through the network that the carbon nanotubes of our products are of high quality, low price and high purity. The purity of our whisker carbon nanotubes is as high as 99.9%, and the multi-walled carbon nanotubes are modified.
The whisker carbon nanotubes independently developed by KELAIWEI nano-carbon materials company have better performance than traditional carbon nanotubes, because the purity of the whisker carbon nanotubes is higher, almost without metal impurities the whisker carbon nanotubes do not block ion transmission, therefore, its conductivity is stronger, and it is very suitable to be used as additive raw materials in lithium battery manufacturing, which can effectively improve the performance and service life of lithium battery, and is modified by multi-walled carbon nanotubes.
