Since its establishment, KELAIWEI company has been committed to the research and development, processing, manufacturing and sales of carbon nanomaterials technology and preparation equipment. The R & D engineers, management personnel and sales personnel of KELAIWEI company come from university research institutions and large enterprises. KELAIWEI company's cooperative customers spread all over over 60 countries and regions such as Europe, America, Asia and Africa. KELAIWEI motivates himself to become the R & D and manufacturing expert of advanced carbon nanomaterials at home and abroad.
How is carbon nanotubes made by chemical vapor deposition? Carbon nanotube materials are widely used and have strong properties, but their production is very low and the manufacturing process is complex. Therefore, scientists have continuously improved the manufacturing methods. Chemical vapor deposition method is used to produce carbon nanotubes, and its production efficiency is still relatively high. By chemical vapor deposition, carbon-containing gases are cracked by catalysts to obtain carbon nanotubes.
Henan KELAIWEI Nano Carbon Material Co., Ltd invested 0.45 billion yuan to build Dengfeng production base of high-end nano materials. This investment is mainly used to expand the production of 3C/digital whisker carbon nanotubes, high-end far infrared paper, high-end thermal conductivity whisker carbon nanotubes material products and high-end power whisker carbon nanotubes, high-end multiplied whisker carbon nanotubes and thermal conductivity whisker carbon nanotubes and many other products. KELAIWEI company will improve its products to meet the increased needs of KELAIWEI customers.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has invested a huge sum of money in technology research and development, and now it has fruitful results. The 106th technology invention patent has been taken in by KELAIWEI Technology Center. KELAIWEI company has a series of technological achievements, such as international PCT patent technology, national patent technology invention achievements, several industrial technical specialties and so on. In the future, the related technological patents KELAIWEI company will continue to obtain.
Phenolic resin carbon nanotube sensor, improving energy density is the current difficulty and pain point of lithium ion battery, silicon carbon negative pole is the future development direction, silicon carbon negative pole in the process of charging and discharging lithium ion battery, the volume expansion of the material will be 200 ~ 400%, and the cycle performance of the battery is poor. Because of the use of sand grinding process to make the paste, the length of the carbon nanotube conductive agent is 0.5 ~ 1μm, the length of the whisker carbon nanotubes is 6 μm, which can still maintain the conductive network when the volume expands when being used as the conductive agent. KELAIWEI cooperates with Company B on the silicon carbon negative pole, which improves the cycle performance, phenolic resin carbon nanotube sensor.
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.
