Description

Technical Field

[0001] This utility model relates to the technical field of graphene, and in particular to a graphite anti-clogging feeding device for graphite conductive coatings. Background Technology

[0002] Graphene is the world's thinnest anti-corrosion material and can be used for metal protection. Numerous studies have shown that graphene's ultra-large specific surface area, excellent barrier properties, high chemical stability, and good electrical conductivity significantly enhance the overall performance of anti-corrosion coatings. These properties include increased adhesion to the substrate, improved wear resistance and corrosion resistance, while also being environmentally friendly, safe, and free from secondary pollution.

[0003] In the production process of graphite conductive coatings, pretreated graphene powder needs to be mixed with solvent, then stirred at high speed, and finally discharged. However, during the feeding process, some graphite fragments are not thoroughly crushed. These incompletely crushed graphite fragments, when fed into the stirring device, cannot be dissolved in time, easily leading to blockage of the discharge port after stirring and feeding. In addition, after the powder and solvent have been stirred and reacted inside the container for a period of time, the graphite powder and solvent are prone to separation. If the powder is fed directly at this time, it can also easily cause blockage of the discharge port. Utility Model Content
