Patent ID: 11261094

Abstract:
The invention provides a method for manufacturing nano carbon micro particles, including the following steps: step one: digesting the Malvaceae plants to produce solutions containing lignin; step two: extracting lignin condensation from the solution containing lignin, and then removing salt from the lignin condensation to form material containing lignin; step three: carbonizing the material containing lignin to form carbides; step four: crushing the carbides; step five: performing high-frequency heat treatment on the crushed carbides to obtain carbon micro particles; further including step six: crushing again the carbon micro particles so that the carbon micro particles are nano-sized and finely pulverized. The high-purity carbon micro particles obtained by the present invention have excellent properties in aspects of conductivity, wear resistance, heat resistance, corrosion resistance, etc., which can be used as an electromagnetic sealing material, a wear-resistant material, a heating element, a heat-resistant material, corrosion resistant materials, the application is extremely wide.
