NOVELTY - The method involves improving utilization rate of graphene comprises continuously arranging self-tape film of the graphene raw material at intervals into the first protective film, adding a layer of the second protective film at the bottom of the first protective film, in the die cutting process, cutting the graphene raw material and the first protective film based on the shape of the product. After the die cutting, the second protective film drives the first protective film and the waste material cut off by the mold to discharge waste. USE - Method for improving utilization rate of graphene. ADVANTAGE - The method enables improving utilization rate of graphene and realizes waste discharging process in a quick and convenient manner. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating the die cutting. Graphene raw material (1) First protective film (2) Second protective film (3) Belt film (4) Electric eye (5)
