Multi-tube graphene preparation equipment and control method thereof

Abstract

The invention relates to equipment for preparing graphene in a multi-tube manner. A method comprises the following steps: arranging a hearth structure on one side of the equipment for preparing the graphene in the multi-tube manner; longitudinally arranging a plurality of groups of heating rods in the hearth structure; arranging the heating rods into a plurality of heating intervals; penetrating corundum tubes into the plurality of groups of heating rods; changing the heating range from high to low; depositing graphene of carbon nano tubes in the corundum tubes; fixing a collecting box body on one side of the hearth structure; and enabling the collection box body to collect graphene through a rapid bin door. The invention solves the the technical problem that: at the present stage, graphene preparation equipment cannot meet the requirements at the present stage due to the fact that the requirement of a coating process on graphene is very high.

Problems solved by technology

[0003] Among the existing preparation methods of graphene oxide film, the graphene film prepared by vacuum filtration method has controllable thickness and high performance, but it takes a long time to form a film and cannot be prepared in batches

The preparation of graphene oxide film by spin coating method and electrostatic self-assembly method takes a long time and low efficiency; coating film formation is a more efficient method for preparing graphene oxide film, and can be prepared in batches. However, coating film formation requires Graphene is made into nano-scale graphene, and then coated through the coating process. At this stage, the coating process has very high requirements for nano-scale graphene, so the current graphene preparation equipment cannot meet the requirements. Require
