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.
After 20 years of persistent research, the expert technical team led by Professor Sun Xiaogang of KELAIWEI company, finally, our KELAIWEI company took the lead in the technical field related to carbon nanomaterials. Our carbon nanomaterials products have undergone the practical cooperative application test of cooperative customers in more than 60 countries around the world, with high performance, strong stability and backup are highly praised by customers, and hydrothermal nano-carbon modification.
Henan KELAIWEI Nano Carbon Material Co., Ltd. is located in Henan province, which is jointly founded by Jiangxi KELAIWEI company and Dengcao group. Our factory covers an area of 12000 square meters and has established ten production lines. With the best-selling products of our company, we have launched two new production lines of whisker carbon nanotubes, with an annual output value of 0.5 billion yuan. KELAIWEI's products are sold to more than 60 countries around the world.
In order to train the management team, strengthen the management of the upper and lower integration, and understand the front-line situation of the company, the group company pays attention to the grass-roots practice of the personnel in the organization, KELAIWEI company responds to the group's call to actively participate in the meeting and study hard. The grass-roots personnel selected by the authorities should abide by the management discipline and work discipline of the temporary enterprise, lower their attitude, go deep into the grass-roots line to understand the actual production, think and analyze the disadvantages and advantages of the current management of the enterprise, and improve the management ability.
The application prospect of carbon nanotubes in modern manufacturing industry is very good. Carbon nanotubes have high elasticity, super hardness (100 times the strength of steel), good infrared absorption performance, high hydrophobic property, smiling volume, very lightweight quality, the density is very low and has very good insulation and other characteristics, so we can conduct in-depth research and expansion on the industrial application of carbon nanotubes.
A brief introduction to the fabrication of carbon nanotubes by arc method. Carbon nanotubes were first discovered by Japanese physicists, and the arc method was also first invented by Japanese scientists. The arc method is to rearrange the structure of carbon atoms in the high temperature environment produced by the arc caused by the graphite electrode of yin and yang poles in the reaction chamber containing the pressure inert gas, so as to obtain a single-wall carbon nano-tube. Since then, the arc method has been continuously improved and perfected day by day.
Graphene is a kind of substance that exists naturally. The accumulation of layers of graphene becomes the graphite that we know everyday. With the progress of human technology, we have further separated a single-layer structure from nature, thus, graphene is a substance. Graphene is generally not suitable to be used as a separate conductive agent. At the same time, flaky graphene is easy to block lithium ions, which cannot pass through the layers and has a long conductive path, at the same time, the edge of graphene is easy to hang functional groups, which is not conducive to improving the electrical conductivity of the electrode. Hydrothermal nano-carbon modification.
