The fourth of the series of "reviewing the development history · encouraging young talents to strive for the first" of KELAIWEI company: 2012 memorabilia. Professor Sun, the technical leader of KELAIWEI company, has led the technical team to develop mass production equipment and improve purity since the synthesis of whisker carbon nanotubes, and finally developed the second generation whisker carbon nanotubes production equipment, the output of our company's whisker carbon nanotubes reached 0.5kg/h.
KELAIWEI company invested 0.45 billion yuan to build dozens of production lines in Henan production base, owning a factory area of 15000 square meters, and designed the production line of whisker carbon nano-tube powder with an annual output of 500 tons, the capacity of the first and second phase projects is 150 tons/year. The company mainly researches and develops whisker nanometer synthesis process and equipment, carbon nanometer powder, carbon nanometer paste, mixed paste and other products.
Henan KELAIWEI Nano Carbon Material Co., Ltd. has established a set of service system and technical training service system with high standards. This service system and service system include skill training for our company's employees, professional service ability training, and also include technical assistance for the cooperative clients of KELAIWEI company. Our company improves the service level of our service personnel through continuous training and assessment, and provides technical assistance to cooperative customers so that customers can use our products quickly.
How were carbon nanotubes discovered? Carbon nanotubes were discovered in the laboratory in 1991 by Japanese physicist Yoshiko Hiroshima. As usual, Yoshima Yoshino, who works in the NEC laboratory of Tsukuba in Japan, was observing the carbon fiber made by the arc method by using the transmission electron microscope, and unexpectedly found "carbon nanotubes". Carbon nanotubes are a kind of "tubular" carbon molecules, whose skeleton is honeycomb-shaped structure.
Chip manufacturing is one of the main battlefields for major powers to compete. Chip manufacturing must use higher standards of materials, and carbon nanotubes are one of the key materials in many materials. Carbon nanotubes have strong conductive and thermal conductivity and super mechanical properties, and high-end carbon nanotubes have become the base material for chip manufacturing. The 500 whisker carbon nano-tube powder production line constructed by Henan KELAIWEI nano-Carbon Material Co., Ltd. will enhance the high-end competitiveness of our products in the nano-material industry.
KELAIWEI company has been working hard for the high-end nanomaterials industry in the motherland for 20 years, and has opened up markets at home and abroad with its independent development of technology and high-end technology services, have deep cooperation with enterprises in more than 60 countries KELAIWEI company has built the project of whisker carbon nanotube powder with annual production capacity of 300 tons, having obtained nine national authorized patents for invention KELAIWEI relies on its own high-end nanomaterials research and development center to continuously provide customers with advanced nanomaterials and technical services, and carbon nanometers are applied in new energy sources.
Carbon nanoparticles are applied in new energy sources. Whisker carbon nanotubes can use powder alone, and the length of powder can reach up to 10μm. In the grinding process of ordinary carbon nanotubes using sand Mill, the length of carbon nanotubes will become shorter. Generally, the length of carbon nanotubes after grinding is generally 0.2 ~ 2μm. In long cycle and high rate lithium ion batteries, the charging and discharging battery materials will expand, using a longer-length conductive agent can maintain the conductive channel during expansion, and the cycle and magnification performance of the battery are improved.
The production system of whisker carbon nanotubes is fully automatic from feeding to product packaging. The growth time of carbon nanotubes is reduced from several hours to several seconds, which is much lower than the production time of traditional process for several hours, the production efficiency and cost have been greatly improved. The self-developed central control system monitors the parameters of the production process in real time, reduces the instability caused by human beings to the products, and the stability of the equipment is good, the product has very good consistency and stability, and this process is a major breakthrough in carbon nanotube synthesis technology.
Efficient production and processing center is the key factor that is related to whether a company's products can be delivered with guaranteed quality as promised. Henan KELAIWEI Nano Carbon Material Co., Ltd attaches great importance to the efficient operation and daily lean management of the production team. We have advanced detection and monitoring device, we have full-time inspectors, and have formulated the quality control and testing system of KELAIWEI. Our company insists on using 6s management and strictly requires ourselves to ensure that the products are completed according to quality and quantity, and carbon nano is applied in new energy.
