Overview of graphene oxide plants

Currently, the main preparation methods used in graphene oxide kits are mechanical methods, oxidation methods, substrate growth methods and liquid phase methods. Most of these production techniques and methods have the disadvantages of low yield, high energy consumption and poor quality, so they are also limited. After relentless efforts, a new processing method has been investigated which can integrate graphene high speed dispersion, crushing and pulverization, vortex cavitation and shear sonication directly in the liquid phase to achieve continuous dispersion and uninterrupted exfoliation of graphite flakes. The graphene oxide kit enables the production of high quality graphene by means of mechanical shearing and hydraulic cavitation, which is favored by most graphene manufacturers.

The graphene oxide plant is a high-tech equipment for the production of high quality graphene such as monolayer and multilayer by mechanical hydraulic shearing and cavitation exfoliation of graphite flakes. The invention and application of this technology has accelerated the pace of graphene production to a certain extent and has increased the confidence of graphene manufacturers in large-scale, low-cost production. Moreover, this mechanical-hydraulic shearing, graphene oxide plant adopts a production process with simple operation, safety and reliability, no oxidation, no high temperature, and high quality, which is ideal for high-volume production of graphene in high volumes.

The process flow of graphene oxide complete sets of equipment:

The production process of graphene: mix graphite powder, dispersant or surface modifier and water in the high shear force dispersion and mixing batching tank for dispersion and mixing, close the circulation valve first, then open the connection valve of storage tank and dispersion grinding pump. The graphite solution passes through the fine dispersion grinder, hydraulic shear vortex cavitator, and then enters the high shear cyclone ultrasonic accumulator under pressure. When there is no material in the dosing tank, the lower connection valve will automatically close and the circulation valve will open to allow uninterrupted circulation of the graphite solution to exfoliate the flakes, thus achieving the desired results for graphene monolayer and multilayer graphene. Graphene oxide kits are also available with computer control or touch frequency control or fully automatic control methods.
