Self-adaptive system for controlling concentration of graphene slurry

Abstract

A self-adaptive system for controlling a concentration of a graphene slurry comprises a slurry mixing unit for mixing graphene powder with water to form the graphene slurry, a concentration monitoringunit used for detecting the concentration of the graphene slurry and connected with the slurry mixing unit, and a control unit connected with the concentration monitoring unit and the slurry mixing unit and used for operating the slurry mixing unit according to a detection result of the concentration monitoring unit so as to control the concentration of the graphene slurry produced by the slurrymixing unit. Compared with the prior art, the technical scheme provided by the invention has the following advantages that the concentration of an existing product can be detected in real time and canbe automatically adjusted as required; the system is simple in structure and can be easily connected to an existing graphene slurry production line; different target gray values can be set as required to obtain graphene slurry products with different concentrations; and a gray scale detection frequency is high, and an action signal can be output in an extremely short time so that the concentration is adjusted.

Description

technical field [0001] The invention relates to the field of graphene preparation, in particular to an adaptive system for graphene slurry concentration control. Background technique [0002] Graphene has excellent optical, electrical, and mechanical properties, and its own non-toxic and good additive characteristics make it widely concerned and applied in the fields of electronics, energy, and materials, and has become a well-deserved "king of materials". ". [0003] In the application process of graphene, especially in the fields of energy storage, batteries, anti-corrosion coatings, etc., graphene particles are often required to be uniformly dispersed in water or other organic dispersants in the form of dispersoids to form a uniform and stable graphene slurry After the material is added, the subsequent application is added. The difference in the concentration of graphene slurry directly determines the difference in its application fields and the properties of the applie...

AI Technical Summary

Problems solved by technology

[0004] In the process of industrialized slurry production, the specified amount of graphene and dispersant are often added according to the pre-determined process parameters, followed by stirring, ultrasonic treatment, etc., but this process is not suitable for continuous and large-scale production processes. And the final dispersion concentration of the slurry can only be known through follow-up inspection and testing. In addition, this traditional production process is not easy to deal with the situation when the process parameters change
