Device and process for preparing graphene heat transfer enhanced organic silicon resin composite pipe

Abstract

The invention discloses a device and a process for preparing a graphene heat transfer enhanced organic silicon resin composite pipe. An outer layer of the composite pipe is a metal pipe, and an innerlayer of the composite pipe is organic silicon resin with graphene added. According to the process principle, the metal pipe which rotates at a high speed and can move axially, a resin conveying pipeand a nozzle which are relatively static are arranged in the metal pipe through a bearing and a steel wire brush, the resin conveying pipe and the nozzle do not participate in rotation and axial movement of the metal pipe, organic silicon resin with graphene added is sprayed to the inner surface of the metal pipe out of the nozzle through a resin pump and a resin conveying pipe, the sprayed metalpipe gradually enters a heat curing device to be heated and primarily cured, a delay controller and a stroke controller are in linkage with a motor to stop rotation of the metal pipe after the resin loses liquidity, the metal pipe is enabled to enter other sections of a curing area, and curing is continued to form the composite pipe.

Description

technical field [0001] The invention relates to a metal / polymer composite pipe forming equipment and process, in particular to a graphene heat transfer enhanced organosilicon resin composite pipe preparation device and process. Background technique [0002] The outer layer and the inner lining of the composite pipe can be made of materials with different characteristics. The outer layer is responsible for bearing pressure and rigid support, and the inner lining is responsible for corrosion resistance and wear resistance. The outer pipe can choose metal pipes with different diameters and wall thicknesses according to the flow and pressure requirements of the conveying medium, such as: hot-dip galvanized steel pipes, straight seam welded pipes, spiral pipes, seamless steel pipes for low and medium pressure fluid transmission, high-pressure boilers And seamless steel pipes, line pipes, etc. for petroleum cracking. According to the chemical composition of the conveying medium, ...

AI Technical Summary

Problems solved by technology

Although epoxy resin and polyethylene have good corrosion resistance, their thermal and electrical properties are poor, which greatly limits the application of this type of plastic-coated composite pipe

[0004] In some occasions with severe corrosion, and where heat exchange is required or liquids are required to prevent static electricity, the inner lining layer has poor thermal conductivity of the resin, while the bimetallic composite pipe has poor corrosion resistance. Not suitable for such conditions
