Laser cleaning method for marine paint

Abstract

The invention provides a laser cleaning method for ship paint, which has the characteristics of good cleaning effect and high efficiency of ship paint, and the cleaning method is green and environmentally friendly, has a wide cleaning range and low cost, and can realize automatic cleaning. Wherein, the present invention provides a laser cleaning method for ship paint, comprising the following steps: step 1, positioning the position on the ship steel plate where the paint layer needs to be cleaned, and determining the position to be cleaned; step 2, according to the properties of the paint layer, Select the parameters of the laser pulse, and perform pulse laser scanning on the surface of the position to be cleaned, so that the paint layer at the position where the paint layer needs to be cleaned is cracked to form paint layer particles; step 3, collecting the paint layer particles ,filter.

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
