KELAIWEI attaches great importance to the work of environmental protection and safety, and always regards the national environmental protection standard as the primary criterion to regulate the production, storage and transportation of products, correct the nonstandard behaviors in production at any time to ensure the discharge of waste water pollutants up to the standard, and the environmental noise emission at the factory boundary conforms to the three standards of "industrial enterprise environmental noise emission standard at the factory boundary" (GB12348-2008), main components of carbon crystal film.
Henan KELAIWEI Nano Carbon Material Co., Ltd. was founded in June, 2018. It is mainly engaged in the research and development and manufacture of whisker carbon nanotubes, and has equipment with annual output of 30 tons of whisker carbon nano tube powder, we have invested 0.45 billion yuan to build the project of whisker carbon nano-tube powder with annual production capacity of 300 tons. This project is carried out in two phases, and the production capacity of each phase is designed to be 150 tons/year, KELAIWEI is committed to promoting the development of the domestic whisker carbon nanotubes industry.
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.
The main components of carbon crystal film, from August 27th to August 29th, 2020, the exhibition center in Shenzhen city, Guangdong province will welcome the international 5G key material industry exhibition summit. KELAIWEI group will participate in this grand meeting as promised. In 2020, the development of 5G commercial equipment at home and abroad will enter an important stage. The prospect of 5G key materials industry will be "bullish". KELAIWEI group has strong technical strength. Our company will certainly bring you surprises in this exhibition.
KELAIWEI company highly praises a new type of material: carbon nanotubes. Carbon nanotubes were found in Coke matters in ethylene cracking furnaces in the 1970 s. After highly graphitized carbon atoms are curled, a tubular structure is formed, which is the carbon nanotubes with high strength, high tenacity and ultra-high conductivity. Henan KELAIWEI Nano Carbon Material Co., Ltd has a production line of 500 tons of whisker carbon nanotubes per year.
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.
After graphite treatment, the atomic arrangement in the material is more regular, and the thermal stability of the material is better. Through thermogravity analysis, it is concluded that the material below 800℃ has very good thermal stability, the thermoweightlessness rate is below 5%. Common carbon nanotubes have many defects in the growth process, at the same time, the crystallization degree is low, and the thermal stability of the materials is poor, generally, obvious oxidation will appear below 500℃, thermal weight loss rate is generally above 20%, and antioxidant capacity is poor.
