KELAIWEI is a high-tech enterprise of carbon nanomaterials. Since the establishment of KELAIWEI, relying on the technical accumulation of over 20 years by Professor Sun Xiaogang's expert team of Nanchang University, KELAIWEI has actively explored the nanomaterials market at home and abroad. In 2008, Professor Sun's team has successfully synthesized whisker-like carbon nanotubes, in 2013, our company has achieved an annual production capacity of 30 tons, and now we have invested 0.45 billion to build a project of 300 tons of whisker carbon nanotube powder.
Carbon nanotubes parent gel, hydrothermal method to prepare carbon nanotubes. 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.
Henan KELAIWEI has a very perfect product research and development system, quality control system and after-sales service system in the industry. KELAIWEI company has strict inspection and assessment standard system in every link from Project establishment and development of products to industrial production, delivery of customers for testing and so on. KELAIWEI is committed to becoming a leader in the high-end nanomaterials industry, serving customers with advanced technology and delivering customers with high-end products.
Whisker carbon nanotubes have always been a difficult problem in production: impurities. The higher the purity of whisker carbon nanotubes, the more advanced it is. At present, there is no whisker carbon nanotubes with 100% purity. At present, the whisker carbon nanotubes produced in the market all contain certain metal impurities. However, KELAIWEI company has been able to control the content of metal impurities in whisker carbon nanotubes within 50ppm.
In the application of carbon nanotubes, capacitors are also an important application direction the main function of capacitors is to store electricity and provide electricity for various electronic products and mechanical equipment, widely used in the mechanical field and other links, the diameter of whisker carbon nanotubes is generally 50-200nm, and the length is from several micrometers to dozens of micrometers. It has large specific surface area and good electrical conductivity, and is an ideal electrode material for supercapacitors, the small supercapacitor cooperating with W is mainly applied to the intelligent three-meter, carbon nanotube parent glue.
The far infrared emission band of the paper produced by our company ranges from 2 nanometers to 20 nanometers, and the electrothermal conversion rate is as high as over 99.5%, which has obvious application effect in the field of thermal products. After our company provided samples for a honeycomb heat exchanger manufacturer in Beijing, the performance of the honeycomb heat exchanger was significantly improved, and the energy-saving effect was obvious after the trial of customers, especially the test of the product quality control department, which could save more than 25% of energy compared with the previous one.
There is an important new type of material in the high-performance polymer composite material industry-ba-based paper. BA-based paper is also called carbon nanotube paper. Carbon nanotubes have high conductivity and strong chemical stability, and high hardness and toughness, which can reach 100 times of the steel strength, but their quality is very, very light, BA-based paper can be obtained by using disordered carbon nanotubes through scientific and complex technical treatment, and Ba-based paper also has some performance advantages of carbon nanotubes.
