▎ 摘  要

NOVELTY - Producing graphite sheet using graphene, comprises subjecting raw material coil to preheating treatment, carbonization treatment, graphitization treatment and cooling treatment in sequence, directly heating up and carrying out the graphitization treatment after the carbonization treatment is completed, where the temperature increase rate of the carbonization treatment is 10-15degrees Celsius/minutes, and the rate of temperature increase of the described graphitization treatment is 6-10 degrees Celsius/minutes. USE - The graphite sheet is useful in electronic product radiating raw material, preferably manufacturing the radiating fin. ADVANTAGE - The graphite sheet has high heat conductivity coefficient, high toughness, high heat flux, good heat dissipation and long heat saturation time, so as to improve the physical performance of the graphene sheet, and the practicability is high. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for radiating graphite sheet.
