The production system of whisker carbon nanotubes is fully automatic from feeding to product packaging. The growth time of carbon nanotubes is reduced from several hours to several seconds, which is much lower than the production time of traditional process for several hours, the production efficiency and cost have been greatly improved. The self-developed central control system monitors the parameters of the production process in real time, reduces the instability caused by human beings to the products, and the stability of the equipment is good, the product has very good consistency and stability, and this process is a major breakthrough in carbon nanotube synthesis technology.
High carbon nano synthetic diamond, KELAIWEI group has been researching and developing for more than 20 years in order to realize the high performance and high stability of domestic carbon nanotube materials. From the establishment of the project by R & D personnel 20 years ago to 2020, 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 through hard work. Our new products and technologies will also be presented to our partners at the International Exhibition of heat conduction and heat dissipation materials and equipment held in Shenzhen Convention and Exhibition Center.
KELAIWEI company's "6s" lean management standard introduces and implements ISO9001 and IATF16949 quality management system, and the quality control department strictly controls the products produced by our company, to ensure the quality and quantity delivery of products for the vast number of cooperative customers. KELAIWEI is a scientific and technological enterprise, adhering to science and technology as the first productive force, striving to be the "leader of high-end Nanomaterials Industry".
KELAIWEI group is looking forward to the 2020 Shenzhen International heat conduction and heat dissipation materials and equipment exhibition as scheduled in Shenzhen Convention and Exhibition Center, China. The staff of KELAIWEI company are always ready to present the new achievements of our company's annual research on high-end nanomaterials. We are looking forward to bringing products and technologies that can help you solve production problems and help you.
Once discovered, carbon nanotubes are destined to become the materials widely used in high-end manufacturing industry the demand of high-end equipment manufacturing industry for materials with higher strength, higher tenacity, higher electrical conductivity and higher thermal conductivity never stops, on the contrary, as the progress of science and technology becomes stronger, and carbon nanotubes are exactly the materials of this kind. KELAIWEI company is looking forward to carrying out deep cooperation with you in the field of carbon nanotubes to produce high-carbon nano-synthetic diamonds.
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.
The purity of carbon nanotubes reflects the technological level of the product. The higher the purity, the greater the technological difficulty. The metal impurity content of ordinary carbon nanotubes is generally above 200ppm, through the high temperature purification process of 3000 ℃, the whisker carbon nanotubes are put into the furnace by using a specific crucible, and the purification time is more than 10 hours. The metal impurities inside the carbon nanotubes can be completely vaporized, the content of metal impurities can be controlled within 100ppm, the purity level is extremely high, and the use of lithium ion batteries is more assured.
