▎ 摘　　要

NOVELTY - The method involves adding graphene powder to an organic solution, stirring uniformly to obtain a graphene solution. The graphite dilute solution on the aluminum plate is uniformly pumped by suction filtration. The graphene solution on the aluminum plate is dried to form a graphene aluminum plate. The stirring is uniform by ultrasonic stirring. The concentration of the graphene solution is from 0.05 mg/ml to 0.5 mg/ml. Heating electrode through power supply socket connected to the power supply solves problem that the canteen heating time is long, the electric quantity is large USE - Method for processing graphene aluminum plate used in thermal lunch box (all claimed). ADVANTAGE - The lunch box has small heating time and the required power is small. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a thermal lunch box. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the thermal lunch box. Box case (1) Liner assembly (2) Cover (3) Fastener (4) Through hole (31)
