More Information
Summary:The invention discloses a feeding method for preparing graphene from a liquid CO2 free carbon atom suspension and a device thereof. The method is characterized in that dead angles of a forcible entryreaction kettle and a feeding device are removed by regulating and controlling the function state and the operation time of controllable valves of a single-acting pump, a double-acting pump or a differential pump, so that all fed graphite powder balls participate in the forcible entry process, and thoroughly forcible entry free carbon atoms have no sedimentation, accumulation, reassembly, combination and crystallization opportunities in the material distribution process. Compared with the prior art, the method has the advantages that the structure is simple, the procedure is easy to control, the forcible entry process is complete and thorough, the mixing of the suspension in the material distribution process is balanced, the concentration is consistent, and the obtained flaky or strip-shaped graphene products are
