USE - Production method of graphene thermally conductive material. ADVANTAGE - Production method of graphene thermally conductive material is not easy to deform, has good impact resistance, and ensures dimensional stability, not only pulverize solid raw materials to speed up mixing and melting, but also achieve the effect of separate delivery of solid and liquid raw materials. The impurities generated by mutual mixing are intercepted to ensure the quality of the finished product. In addition, during the operation of the twin-screw granulator, surface is also be cooled by water cooling, which further improves the service life of the twin-screw granulator.
