▎ 摘 要
NOVELTY - A spliced type track sterilizer comprises a power supply device whose outer surface is covered with loose porous graphene material. USE - The spliced type track sterilizer is useful for sterilizing cold chain food, import and export goods, and mobile population portable goods. ADVANTAGE - The spliced type track sterilizer uses graphene material, which has excellent thermal conductivity and thermal insulation performance. The power supply device can work normally at -40℃. The sterilizer with the power supply device has wide range of applications. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a graphene material; and use of the graphene material for thermal insulation.
