NOVELTY - Preparing graphene film involves injecting graphene powder debris into circulating air duct and pressurizing by air stream. The airflow of turbofan is diffused through the jet to annular belt support and hollow graphene adhesion area of pressure-sensitive adhesive tape is sealed. The wind pressure is further expanded to the contact surface and the wind resistance area is reduced. USE - Method for preparing graphene film by air circulation (claimed). ADVANTAGE - The method enables to prepare graphene film by air circulation in a safe, convenient and eco-friendly manner. The non-stick belt is used as the carrier in the production, graphene film, stripping glue layer and a transferable adhesive. The viscous adhesive tape is used as a carrier, a viscose layer of a graphene adhesive tape. The graphene film is laminated and laminated to produce a graphene sheet. DETAILED DESCRIPTION - Preparing graphene film involves injecting graphene powder debris into circulating air duct and pressurizing by air stream. The airflow of turbofan is diffused through the jet to annular belt support and hollow graphene adhesion area of pressure-sensitive adhesive tape is sealed. The wind pressure is further expanded to the contact surface and the wind resistance area is reduced. The graphene fragment portion longitudinally touch sensitive adhesive because of the small contact area. The attendant is not touch sensitive adhesive of graphene fragments. The wind is allowed to enter to the circulating air channel and the identical pressure sensitive adhesive tape fragments of graphene is converted to into graphene tape. The finished graphene tape is formed by the double pressing of the roller by elastic pressing to form the graphene film. The air circulating device comprises circulating air channel (1), pressurizing fan, jet (3), graphene adhesion area (4), filling, pressure sensitive tape, graphene tape, elastic pressure roller, supporting endless belt, driven roller (10), driving roller (11) and the endless belt support roller. The circulating air exhaust is upper part, two side deformation is oval, one side of lower distortion and shrinkage is a straight jet. The bottom is design with a rectangular hollow graphene region. An upper bobbin is set with pressure vortex fan. The attached annular belt is long and the width greater than the circulating air duct rectangular hollow area of no joint ring belt. An endless belt supported by the active and passive roller and supporting the pressure-sensitive adhesive tape sealing rectangular hollow area forming a graphene adhesion area. A driving roller of the driving roller is set with the endless belt support roller. The elastic pressurizing roller is controlled by an elastic pressure of two groups of controllable pressure such as pressure or differential pressure rollers. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene film synthesizing device.
