▎ 摘  要

NOVELTY - The enhanced corrosion resistant and radiation-resistant thermal conductive graphene coating comprises graphene coating layer which is provided with a thickness of 1-10 mu m and is coated on the surface of high-level radioactive glass curing container. The radioactive glass curing container is made of austenitic stainless steel. USE - Enhanced corrosion resistant and radiation-resistant thermal conductive graphene coating for high-level radioactive glass curing container (claimed). ADVANTAGE - The corrosion resistance of the treating container is improved and physical and chemical properties of graphene are excellent. The performance of the container is excellent and life time period is extended. The temporary storage of container is increased. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) high-level radioactive glass curing container which comprises graphene coating; and (2) preparation of graphene coating, which involves adding graphene oxide to certain amount of aqueous solution, and oxidizing, so that graphene is evenly dispersed in the aqueous solution and the graphene oxide is reduced, to obtain graphene dispersion, treating the outer surface of the glass curing container to remove the oxide layer on the surface, applying the graphene oxide to the surface of the high-level radioactive glass curing container, solidifying the high-level radioactive glass curing container containing the graphene-coated layer by heating at 150-250 degrees C for 3-5 hours, under inert gas-protected environment, removing the moisture in the graphene oxide and oxidizing, so that graphene is firmly bonded to the surface of high-level waste glass curing container.
