Graphene production equipment
Overview of graphene production equipment
At present, the preparation methods of graphene are mainly mechanical method, oxidation method, substrate growth method and liquid phase method. Most of these production techniques and methods have shortcomings such as low yield, high energy consumption, and poor quality, and thus are also limited. Production and development of domestic graphene. Nantong Fleck Graphene Production Research Group has made unremitting efforts to invent a graphene which is continuously dispersed in the liquid phase and continuously stripped graphite sheets by high-speed dispersion, crushing and grinding, vortex cavitation and shearing ultrasonic. The production line has realized the production of high-quality graphene by mechanical shearing fluid cavitation and other technical means, which is favored by the majority of graphene producers.
The graphene production equipment is a high-tech advanced equipment for high-quality graphene such as single layer and multi-layer produced by mechanical hydraulic shearing and cavitation stripping of graphite sheets. The invention and application of this advanced technology have accelerated the pace of graphene production to a certain extent, and also promoted the confidence of graphene production enterprises in large-scale, high-efficiency, low-cost, pollution-free production. Moreover, the production process of the mechanical hydraulic shearing and cavitation vortex stripping graphite sheet has the characteristics of simple operation, safety and reliability, no oxidation, no high temperature, high quality and high quality, and is very suitable for mass production of high quality graphene.
Graphene production equipment process
Graphene production process: Firstly, the high-shear dispersion stirring batching tank is equipped with graphite powder, dispersant or surface modifier and water to disperse and stir, first close the circulation valve and then open the storage tank and the dispersion grinding pump connection valve. The graphite solution is passed through a fine dispersion mill, a hydraulic shear vortex cavitation, and then a pressure into a high shear cyclone ultrasonic hopper. When the batching tank is empty, the lower connecting valve is automatically closed and the circulation valve is opened to allow the graphite solution to continuously unravel from the circulation to make the graphene single layer multi-layered to the desired effect, and the pressure control, time control and temperature control are designed in the integrated control system. You can also use computer control or touch frequency control or fully automatic control.
