KELAIWEI makes high-performance and stable carbon nanotubes. At the beginning of its establishment, KELAIWEI paid attention to maintaining technical advantages and maintained close cooperation with university research institutions and expert teams. Our company has deeply cooperated with Professor Sun Xiaogang's team and has applied for more than 100 invention patents, of which nine have obtained national authorized invention patents and two international PCT patents. Relying only on technical advantages, KELAIWEI's products have been completed from Henan and Jiangxi to more than 60 countries in the world.
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.
Water-based carbon nano-tube floor manufacturer, Henan KELAIWEI nano-Carbon Material Co., Ltd. Independently developed, processed and prepared far infrared heating paper batch production line equipment has achieved an annual capacity of 60 tons, and our company is fully capable of expanding the production capacity of far infrared heating paper at any time to meet the huge demand of customers for far infrared heating paper. In addition, our company spent 0.45 billion yuan to design and develop the whisker carbon nanotube powder engineering project, which will achieve an annual production capacity of 300 tons.
The technology center of Henan KELAIWEI Nano Carbon Material Co., Ltd is very happy to compete with the technology center of Jiangsu KELAIWEI Nano Carbon Material Co., Ltd ". The two R & D bases of our company promote the technological progress of our company through cooperation and friendly competition. Colleagues from the technology center of Henan KELAIWEI Nano Carbon Material Co., Ltd reported good news again that the 9th National technology patent has been successfully declared.
Using the far infrared transmitting paper made of whisker carbon nanotubes and high-temperature fiber, the far infrared transmitting paper can heat objects by emitting far infrared waves under electrification, and can be applied to aircraft wing deicing in the field of high-temperature heating, high-voltage wire deicing, Car Rearview mirror heating water mist removal, electric steering wheel, water heater, electric kettle, electric lunch box, fast liquid heat exchanger, solar seawater desalination evaporator, etc., heating temperature is generally above 100℃, at present, the market scale is over 100 billion.
The far infrared emission band of the far infrared paper produced by our company ranges from 2 nanometers to 20 nanometers, and the electrothermal conversion rate is as high as over 99.5%. The application effect in the field of thermal products is obvious. After our company provided samples for a honeycomb heat exchanger manufacturer in Beijing, through the customer's trial, especially the inspection of the product quality control department, the performance of the honeycomb heat exchanger is significantly improved, and the energy saving effect is obvious. Compared with the previous one, it can save more than 25% of energy.
After more than 20 years of research, the technology center of KELAIWEI company has been able to manufacture ultra-high purity whisker carbon nanotubes with a purity of 99.95%. Henan KELAIWEI carbon nanotube material Co., Ltd. and many high-end battery manufacturers at home and abroad have found in practical application research that whisker carbon nanotube is a very ideal conductive additive for positive and negative electrode materials of lithium batteries, it can effectively improve the battery life and capacity.
