The research and development cycle of whisker carbon nanotubes is long, and it is not easy to achieve a breakthrough in a short time. Ordinary carbon nanotubes all use solid catalysts to deposit the catalysts on the surface of carrier materials, carbon nanotubes are synthesized by introducing hydrocarbon gas after calcination and reduction. Compared with traditional carbon nanotubes, the process technology of whisker carbon nanotubes is more complicated. In the process of synthesizing whisker carbon nanotubes, improper regulation may lead to the growth of non-linear ordinary carbon nanotubes, the product has high requirements for process control.
By virtue of its own national invention patent technology and technical professional service team and sales team, KELAIWEI nano carbon materials have been spread through market inspection and customer reputation in the past 20 years. Cleway's products have been sold well in China and are exported to the world at present, our company has invested 0.45 billion in the construction of 300 shield/year production capacity of whisker carbon nanotube powder project and reached cooperation with customers in Europe, America, Asia, Africa and other regions to actively expand the nanomaterials market, power consumption of carbon crystal electric heating.
Since the establishment of Henan KELAIWEI Nano Carbon Material Co., Ltd., relying on the technical accumulation of the company's technical team for more than 20 years, it has achieved a leap-forward and rapid development. KELAIWEI company has developed into a technical backbone enterprise in the high-end nanomaterials industry. In 2008, the company has invested 0.45 billion yuan to expand the production capacity of whisker carbon nanotubes, and this whisker carbon nanotube powder project will achieve an annual production capacity of 300 tons.
Carbon crystal electric heating power consumption, KELAIWEI's lean improvement work has achieved important achievements: complete the company-Level 5S Bronze Certification. This is the inevitable result of the company's concerted efforts and earnest study and practice. KELAIWEI rapidly promoted the lean management work and achieved gratifying results by issuing questionnaires, books, excellent tweets of the company's public number, training of lean trainers of the group company, internal and external communication and learning, etc.
Henan KELAIWEI Nano Carbon Material Co., Ltd. Always pays attention to the industry frontier trends. It is reported that a large company in South Korea recently invested more than 0.3 billion yuan to expand its carbon nanotube material production capacity. After the successful implementation of the project, its carbon nanotube production capacity will be expanded to 1700 tons per year. Carbon nanotubes have a wide range of applications because their conductivity and thermal conductivity are comparable to those of diamond and copper materials.
How is graphene thermal film obtained? Put copper metal current-carrying strip, silver strip and graphene conductive layer between two layers of polyester film, and use science and technology to obtain graphene heating film after a series of processing. Henan KELAIWEI Nano Carbon Material Co., Ltd. found that in recent years, there have been some new types of floor heating in Jiangsu and Zhejiang areas, among which there are cases of using graphene heating film to make electric floor heating materials, which are quite popular in the market.
The resistivity of powder is an important index to characterize the electrical conductivity of materials. The lower the resistivity, the better the electrical conductivity of products, under the pressure of 20Mpa, the powder resistivity value of whisker carbon nanotubes can reach below 8mΩ · cm, and the resistivity of ordinary carbon nanotubes is above 15mΩ · cm, the resistivity of conductive carbon black is above 100mΩ · cm, and the resistivity of whisker carbon nanotubes is the lowest, which can ensure ultra-high conductivity on lithium ion batteries and composite materials.
