Problems solved by technology

The existing tube inner wall coating technology is mainly aimed at the surface treatment of the inner wall of the metal pipe. The method used is to carry out ion coating from one side of the tube mouth to the other side. The film treatment at the entrance of the inner wall of the tube is faster and the thickness is the thickest. , the inner wall of the pipe gradually extends into the pipe, and the thickness gradually decreases, which leads to uneven thickness of the coating film, and it is difficult to ensure the consistency of the bonding force

Abstract

The invention discloses an inner wall coating device for an insulating material pipeline. The device comprises a secondary sputtering electrode and rotation equipment, wherein the cathode target material of the secondary sputtering electrode is arranged in a to-be-coated insulating material pipeline in a penetrating manner along the axial direction, and the rotation equipment is fixedly connectedwith one end of the to-be-coated insulating material pipeline; and the secondary sputtering electrode and the rotation equipment are arranged in vacuum equipment, and the vacuum equipment enables thedevice to be in a vacuum environment. The inner wall coating device is suitable for coating the inner wall of an insulating material pipeline having a small-sized inner diameter, and the coating filmhas uniform thickness and accordant bonding force.

Description

Technical field [0001] The invention relates to the technical field of coating, in particular to a coating device for the inner wall of an insulating material pipeline. Background technique [0002] The surface treatment of the inner wall of the tube and tube has always been a problem of plasma surface modification, especially for the tube with a thinner inner diameter, a larger long diameter and a reduced diameter, it is difficult for the plasma to enter the tube, so the treatment is more difficult. At present, the tube inner wall coating technology adopts the inner wall coating method composed of arc ion plating and electromagnetic coil device, which is mainly applied to the coating of metal large-diameter tubes. The existing tube inner wall coating technology mainly deals with the surface treatment of the inner wall of the metal pipe. The method used is to carry out ion coating from one side of the nozzle to the other side. The coating is processed faster at the entrance of th...
