Title:
METHOD FOR PRODUCING CARBON NANOTUBE STRAND WIRE AND CARBON NANOTUBE STRAND WIRE PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/026951
Kind Code:
A1
Abstract:
As a method for producing a carbon nanotube strand wire capable of efficiently producing a carbon nanotube strand wire in a tubular carbon nanotube synthesis furnace, a gas flow for adhesion suppression is generated from a gas for adhesion suppression release port located between the second end of the carbon nanotube synthesis furnace (side on which carbon nanotube strand wire is recovered) and the end in the heating device on the second end side in a direction from the second end toward the first end (side on which carbon-containing gas is supplied) between the inner wall of the carbon nanotube synthesis furnace and the outer wall of a first flow path for orienting carbon nanotubes to form a carbon nanotube strand wire to suppress the adhesion of a plurality of carbon nanotubes to the inner walls of the carbon nanotube synthesis furnace.
