Overview of complete sets of graphene oxide equipment
At present, the preparation methods used in the graphene oxide complete equipment are mainly mechanical methods, oxidation methods, substrate growth methods and liquid phase methods. Most of these production technologies and methods have the disadvantages of low yield, high energy consumption and poor quality, so they are also limited. After unremitting efforts, a new processing method has been developed, which can directly integrate graphene high-speed dispersion, crushing and pulverization, vortex cavitation and shear ultrasound in the liquid phase to achieve continuous dispersion and uninterrupted graphite flakes. Exfoliation. The complete set of graphene oxide equipment realizes the production of high-quality graphene through technical means such as mechanical shearing and hydraulic cavitation, which is favored by most graphene manufacturers.
Graphene oxide complete equipment is a high-tech equipment for producing high-quality graphene such as single-layer and multi-layer through mechanical hydraulic shearing and cavitation exfoliation of graphite sheets. The invention and application of this technology has accelerated the pace of graphene production to a certain extent, and has also strengthened the confidence of graphene manufacturers to carry out large-scale and low-cost production. Moreover, the production process adopted by this mechanical hydraulic shearing and graphene oxide complete equipment has the characteristics of simple operation, safety and reliability, no oxidation, no high temperature, and high quality, which is very suitable for high-yield mass production of graphene.
Graphene oxide complete sets of equipment process:
The production process of graphene: mix graphite powder, dispersant or surface modifier and water in a high shear force dispersion mixing tank, perform dispersion mixing, first close the circulation valve, and then open the connecting valve of the storage tank and the dispersion grinding pump. The graphite solution is passed through a fine dispersion mill, a hydraulic shear vortex cavitator, and then under pressure into a high shear cyclone ultrasonic accumulator. When there is no material in the batching tank, the lower connecting valve will automatically close and the circulation valve will open, so that the graphite solution will circulate uninterruptedly to peel off the sheet, so as to achieve the ideal effect of graphene single-layer and multi-layer graphene. Graphene oxide packages can also use computer control or touch frequency control or fully automatic control methods.
