The company has a special R & D department, and each project team under the R & D department is specially responsible for promoting process R & D, optimization, innovation and promotion, improving the level of construction technology and enhancing the company's construction service advantages in the industry. The project team is engaged in the research and development of whisker carbon nanotubes and the innovation of technology. The R & D department has established a standard project development process, adopting the method of setting up scientific and technological projects and combining production, teaching and research to carry out the R & D of new products in the field of nano carbon materials.
KELAIWEI Group has researched and developed 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.
Henan KELAIWEI Nano Carbon Material Co., Ltd., which has invested in the research and development of high-end nano materials for many years, has owned 9 national authorized technology invention patents and 2 international PCT patents, we have completed the enterprise's scientific research target of publishing more than 40 industry papers. In addition, our company has also published two monograph on carbon nanotube industry and has reached cooperation with many domestic universities. Therefore, KELAIWEI company has very strong technical research and development strength.
The project of the annual output of carbon nanotubes of Henan KELAIWEI company reaching 300 tons has been implemented Henan Kaifeng Henan KELAIWEI company has invested 0.45 billion yuan in the research and development, production and manufacture of high-end nanomaterials and equipment to promote social development with science and technology, at the same time, KELAIWEI company insists on promoting the development of the company with high and new technology products and contributes little to the economic development of Kaifeng. It is the leading stock of nano-carbon materials.
The basic research of carbon nano-tube materials is very important. At present, our country is in the dominant position in the aspect of the preparation and application research of carbon nano-tube materials. Carbon nano-tube materials are very fine, with very high conductivity and thermal conductivity, and the hardness is 100 times of steel, the higher the purity, the stronger the performance of carbon nanotubes. The technical team of KELAIWEI carbon nanomaterials company will continue to demand to contribute to the development of nanomaterials in our country.
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 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.
