A brief look at the graphene conductive slurry kit


At present, the preparation methods used for graphene conductive paste sets are mainly mechanical, oxidation, substrate growth and liquid phase methods. Most of these production techniques and methods have the disadvantages of low yield, high energy consumption and poor quality, and therefore also have certain limitations. After persistent efforts, a new processing method has been developed. This method can integrate high-speed dispersion, crushing and smashing, vortex cavitation and shear sonication of graphene directly in the liquid phase to achieve continuous dispersion and uninterrupted peeling of graphite flakes. Graphene conductive slurry complete set of equipment through mechanical shear, hydraulic cavitation and other technical means to achieve the production of high-quality graphene, by the majority of graphene manufacturers.

Graphene conductive slurry complete set of equipment is a high-tech equipment for the production of high quality graphene such as single-layer and multi-layer by mechanical hydraulic shearing and cavitation peeling of graphite flakes. The invention and application of this technology has, to a certain extent, accelerated the pace of graphene production and enhanced the confidence of graphene manufacturers in large-scale, low-cost production. Moreover, this mechanical-hydraulic shearing, graphene conductive paste production process adopted by the complete set of equipment has the characteristics of simple operation, safety and reliability, no oxidation, high temperature resistance and high quality, which is very suitable for high volume production of graphene.

Graphene conductive paste complete sets of equipment process flow:

The production process of graphene conductive paste complete set of equipment: mix graphite powder, dispersant or surface modifier and water in high shear dispersion mixing batching tank for dispersion mixing, first close the circulation valve, 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 connecting valve closes automatically and the circulating valve opens to make the graphite solution circulate uninterruptedly to strip the sheet, so as to achieve the ideal effect of graphene monolayer and monolayer. Graphene conductive slurry complete set can also be controlled by computer or touch frequency control or fully automatic control.
