May Day 2020 is a special Labor Day. The staff of Henan KELAIWEI Nano Carbon Material Co., Ltd. should rest and work on duty under the protection of individual epidemic. KELAIWEI company delivers holiday comfort and welfare to all employees. Under the influence of the current epidemic situation, the economic situation is grim. KELAIWEI company insists on doing a good job in protection and actively reproduces to contribute to the economic development of our city.
Henan KELAIWEI Nano Carbon Material Co., Ltd. will briefly introduce carbon nanotubes to you today. Carbon nanotube materials were first discovered in coking materials of ethylene cracking furnaces in the last century. The ultra-high strength of carbon nanotubes can be 100 times that of steel, and at the same time it has good electrical and optical characteristics. After being used as the battery anode additive, it can reduce 30% of the conductive materials, and filling the anode of the required materials can greatly improve the battery capacity.
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.
The preparation method of ordinary carbon nanotubes adopts the method of preparing solid catalyst first, and then preparing at high temperature cracking under the action of reducing gas. The solid catalyst commonly used in the catalyst has catalyst carrier, generally, it is not easy to remove, resulting in high ash content. The whisker carbon nanotubes adopt floating gas phase catalysis method, and there is no need to separately prepare solid-state catalyst. The synthesis process cycle is short, and the process is relatively simple, the purification process is high temperature purification with low ash content.
