▎ 摘　　要

NOVELTY - Graphene vacuum sealing and transferring device comprises a sealed cylinder (1). An etching solution container (2) is placed inside the upper end of the sealed cylinder. The lower end side of the etching liquid container is provided with an edge-increasing plate (3) connected by screws. An outer sealing groove is opened on the upper end of the edge increasing plate. The one end of the outer sealing card (5) is placed at the inner end of the outer sealing groove. A built-in groove is opened at the lower end of the edge increasing board. A rubber gasket (11) connected by glue is provided at one end of the sealing pressure plate. A locking posts (12) connected by screws are symmetrically arranged on both sides of one end of the etching liquid container. The two sides of the upper end of the sealing cylinder are symmetrically provided with receiving posts (14) connected by screws. USE - Graphene vacuum sealing and transferring device. ADVANTAGE - The graphene vacuum sealing and transferring device ensures that the etching liquid inside the container will not leak, and ensures a suitable working volume of the etching liquid inside the sealed cylinder. DESCRIPTION OF DRAWING(S) - The drawing shows sectional front view of an graphene vacuum sealing and transferring device. Sealed cylinder (1) Etching solution container (2) Edge-increasing plate (3) Outer sealing card (5) Rubber gasket (11) Locking posts (12) Receiving posts (14)
