KELAIWEI attaches great importance to the work of intellectual property rights, from patents, trademarks to corporate image and so on. Invest 5% of the sales volume into the research and development of new products every year. The company should cope with the competition, practice hard, reshuffle the industry and comprehensively improve the comprehensive competitiveness. To upgrade and iterate the products and maintain the competitive advantage of KELAIWEI's products in the industry, it is in the dominant position.
In 2020, KELAIWEI had been deeply engaged in the research and development and preparation of nanomaterials for 20 years. Our company fully owns independent intellectual property rights of relevant industries and has applied for 106 patents (including 9 national authorized invention patents and 2 international PCT patents). Our deep cooperation customers have spread all over the world (more than 60 countries such as Asia, America, Europe and Africa). All the staff of KELAIWEI are forging ahead and looking forward to establishing a deep partnership with you.
KELAIWEI company relies on the research and development achievements of the expert research and development team of Professor Sun Xiaogang of Nanchang University in China for more than 20 years to carry out the industrial and mass production application of high-end nanomaterials. After years of unremitting efforts and continuous investment, our company has achieved the production capacity of far infrared heating paper reaching 30 tons per year, and the production capacity of designed whisker carbon nanotube powder production line reaching 300 tons per year, around 2008, 0.45 billion yuan has been spent on production capacity expansion.
The meeting of the improvement office of the group was held through the video of "DingTalk". Director Yuan Hongwei of the improvement office of the group arranged five key tasks to carry out questionnaires with the theme of lean improvement, to investigate the current situation of the enterprise and to grasp the voice of the employees of the enterprise, do a good job in the next lean work pay special attention to the appraisal work of excellent improvement specialists, actively participate in the second lean tools competition, implement the 5S silver certification training plan, carbon fiber carbon crystal electric heater.
There are many production methods of carbon nanotubes, among which the widely used production method of carbon nanotubes is arc discharge method, which is also a relatively simple method in the preparation of carbon nanotubes. Therefore, correspondingly, the purity of carbon nanotubes made according to this method is also relatively low. In fact, what this method obtains is multilayer carbon nanotubes. Henan KELAIWEI Nano Carbon Material Co., Ltd. has been able to produce whisker carbon nanotubes with purity up to 99.99%, carbon fiber carbon crystal electric heater.
Fundamentally speaking, are there any essential differences between common carbon nanomaterials and graphene? Graphene is a thin film material. The thickness of graphene is only one carbon atom. The mechanism of graphene is fundamentally different from that of common carbon nanomaterials. Graphene, fullerene nanomaterials, carbon nanotube nanomaterials and so on, these carbon nanomaterials are different in structure and form, it can be said that the physical properties of graphene and carbon nanomaterials are still different.
Whisker carbon nanotubes are purified at high temperature with low content of metal impurities, which can be directly used in the form of powder. Ordinary carbon nanotubes use grinding technology to prepare conductive paste, during the high-speed grinding process of the equipment for preparing conductive paste, due to the collision of zircon beads, metal impurities will be generated, which will affect the self-discharge of the battery and the safety performance of the product, metal Impurities will pierce the membrane of lithium ion battery and cause short circuit of the battery. Power battery has extremely strict requirements on this index, and whisker carbon nanotubes are safer to use.
