Plasma source structure for removing surface coating

Abstract

The invention discloses a plasma source structure for removing a surface coating, which comprises a plasma generator and a guide blade, wherein the plasma generator generates a plasma beam, and the plasma beam and a substrate material are arranged in an included angle shape with a high left part and a low right part; an upper thin-layer gas generator is arranged on the upper portion of the plasma generator and generates upper thin-layer reaction gas, the upper thin-layer reaction gas and the plane where the substrate material is located form an included angle with the left higher than the right, and the guide blade is located below the plasma generator. The guide blade generates lower thin-layer reaction gas, the lower thin-layer reaction gas and the plane where the substrate material is located are arranged in an included angle shape with the left higher than the right, and the intersection position of the upper thin-layer reaction gas, the plasma beam and the lower thin-layer reaction gas acts on the combination position of the substrate material and the coating, so that combination of the coating and the substrate material is damaged. And the effect of removing the coating from the surface of the substrate material is achieved.

Description

technical field [0001] The invention belongs to the field of material surface coating removal, in particular to a plasma source structure used for surface coating removal. Background technique [0002] Coating is a chemical mixture paint that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. For different applicable environments and purposes, paints or coatings are widely used in society and even in the military. However, the long-term service of the coating material in the air or in complex working conditions (such as highly corrosive air environment, high temperature environment, etc.), after a certain period of service, will cause the coating to fall off and fail. Replacement is required to ensure its performance. The current coating removal methods mainly include sandblasting, grinding, plastic medium sandblasting, laser ablation, ultraviolet rapid ablation, water jet, frozen CO2 particles, etc. These methods eithe...
