▎ 摘　　要

NOVELTY - The device comprises a three-layer structure and the outer layer metal tube. The inner diameter of the metal tube is not less than 25 milimeter. The middle layer is phenolic resin added with graphene. The thickness is 0.1-1 milimeter. The mass percentage of graphene in the phenolic resin layer is 0.5-8 percentage weight, and the inner layer is phenolic resin. The thickness is 0.05-0.2 milimeter. The adding method of the graphene is that the graphene is added to the strongly stirred resin through a sieve screening method. The moving motor drives the metal pipe, which rotates device through the transmission wheel and the transmission belt. The support of the metal tube support frame moves back and forth on the moving guide. The movement of the support is controlled by the stroke controller and the delay controller linked to the mobile motor. USE - Device for producing graphene heat transfer reinforced multilayer composite tube. ADVANTAGE - The graphene heat transfer reinforced multi-layer composite tube production device has high production efficiency, compact composite layer and high bonding strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing a multilayer composite pipe. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the device for producing graphene heat transfer reinforced multilayer composite tube.
