At present, there are four companies in the world that can carry out mass production of whisker carbon nanotubes, which are Japan SHOWA SENKO, Taiwan rijiang, US Applied Sciences and our company respectively. Among them, Japan has the largest production of SHOWA SENKO, up to about 500 tons. The technology and equipment of whisker carbon nanotubes developed by our company are at the same level as SHOWA SENKO. Only KELAIWEI company can produce mass production in China, and its technology belongs to international advanced, which is the mainstay in China.
KELAIWEI company will continue to invest in top expert teams and research and development funds to devote itself to the research and development of nanomaterials technology and equipment, providing you with high stability, nanomaterials products with high technical standards in the past 20 years, the R & D team of KELAIWEI company-the expert team led by Professor Sun Xiaogang of Nanchang University has independently researched and developed the production and preparation technology of whisker carbon nanotubes, our company has invested 0.45 billion in the construction of whisker carbon nanotube powder project, and now KELAIWEI products have been exported to the world, including carbon crystal floor heating and electric heating film floor heating.
KELAIWEI company invested 0.45 billion yuan to build a production workshop of 13,000 square meters in the industrial park of Dengfeng city, Henan province. This expansion project will plan several production lines, and strive to expand the production capacity of the whisker carbon nanotube powder project to an annual output of 500 tons, in order to meet the sudden increase in customer demand. Our company adheres to the "6s" lean management method to efficiently recommend all kinds of work to ensure that the products are delivered to customers on time and with high quality.
In special times, we should strive more. In April, our company held a symposium to consolidate the promotion year. The sales directors and advanced sales representatives of each center communicated and learned with each other, and everyone spoke freely, analyzed the current product sales situation, problems and solutions, and the chairman of the board fully affirmed everyone's work achievements, at the same time, we also encourage everyone to learn from first-class enterprises such as Huawei and Alibaba, and do a good job in our annual sales in 2020.
Carbon crystal floor heating and electric film floor heating, carbon nanotubes are divided into different types according to different standards. Carbon nanotubes are formed after the graphene sheets are curled. Therefore, if we divide them according to the number of layers of graphene sheets, we can divide them into single-walled carbon nanotubes and multi-walled carbon nanotubes. According to the internal structural characteristics of carbon nanotubes, carbon nanotubes can be divided into sawtooth-shaped carbon nanotubes, armchair-shaped carbon nanotubes and other types.
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.
After graphite treatment, the atomic arrangement in the material is more regular, and the thermal stability of the material is better. Through thermogravity analysis, it is concluded that the material below 800℃ has very good thermal stability, the thermoweightlessness rate is below 5%. Common carbon nanotubes have many defects in the growth process, at the same time, the crystallization degree is low, and the thermal stability of the materials is poor, generally, obvious oxidation will appear below 500℃, thermal weight loss rate is generally above 20%, and antioxidant capacity is poor.
