Laser cleaning method for marine paint

Abstract

The invention provides a laser cleaning method for marine paint. The laser cleaning method for the marine paint has the characteristics of being good in marine paint cleaning effect and high in efficiency. The laser cleaning method for the marine paint is green and environmentally friendly, wide in cleaning range, low in cost and capable of realizing automatic cleaning. The laser cleaning method for the marine paint comprises the following steps of (1) positioning the part, with the need for cleaning of a paint layer, on a ship steel plate and determining a position to be cleaned; (2) selecting parameters of laser pulse according to the property of the paint layer and then conducting pulse laser scanning on the surface of the position to be cleaned to make the paint layer of the position to be cleaned crack and form paint layer particles; and (3) collecting and filtering the paint layer particles.

Description

technical field [0001] The invention relates to the technical field of surface coating cleaning, in particular to a laser cleaning method for ship paint. Background technique [0002] The harsh corrosive environment of the ocean has a very important impact on the service life and navigation performance of ships. In order to minimize the corrosion of hull materials, various protective methods have been adopted for ships from design to manufacture. Among them, anti-corrosion coating is the most extensive and convenient means of protection. [0003] When the coating is aged, polluted, damaged or cannot play its due protective role due to other reasons, it is necessary to repaint the hull surface coating. In the process of changing the coating of the hull, the original coating needs to be cleaned to ensure the cleanliness of the surface when the new coating is subsequently covered, and to ensure the adhesion effect and coating quality of the new coating and the surface of the ...

Problems solved by technology

However, chemical cleaning methods can easily lead to environmental pollution, and the cleaning effect is limited. When the attached old paint layer has complex components, it is necessary to select a variety of cleaning agents to meet the requirements.

[0013] In summary, although the existing ship paint removal methods can realize the cleaning of ship steel plate primer and topcoat, they all have problems such as poor cleaning effect, low efficiency and environmental pollution to varying degrees, which greatly limit the application of the above methods. promotion and application

[0014] Therefore, how to solve the shortcomings of poor cleaning effect and low efficiency of ship paint removal is a technical problem to be solved
