AI Technical Summary

Problems solved by technology

[0003] At present, in the existing equipment for preparing graphene such as high-temperature furnaces and vacuum quartz chambers, the length of the vacuum quartz chambers installed in the middle of the horizontal high-temperature furnace body needs to be three times the length of the furnace body. After the growth of graphene is completed, the thermal field It cannot completely leave the vacuum quartz chamber, and the equipment does not have a cooling device, so it cannot achieve rapid cooling after the growth of graphene materials

Moreover, both ends of the vacuum quartz chamber are fixed, the furnace body cannot be moved out of the quartz chamber, and the continuous growth of graphene materials cannot be realized.
