Carbon nanopolymer materials represent an innovative application of carbon materials. Their raw materials and production processes generate significantly less carbon emissions compared to traditional repair methods and similar products. In use, their excellent lubrication, wear resistance, and corrosion resistance effectively reduce frictional resistance in equipment operation, extend equipment service life, and systematically achieve energy conservation and emission reduction. These materials are advanced technologies and green products that help enterprises reduce carbon emissions and accord with the national "Double Carbon" strategy.
