Traditional cleaning methods include mechanical cleaning, chemical cleaning, ultrasonic cleaning, sandblasting and dry ice cleaning. The application is relatively mature, and the application of environmental protection and high precision requirements is greatly limited; traditional chemical cleaning methods include mechanical cleaning, chemical cleaning, and ultrasonic cleaning. , sandblasting and dry ice cleaning, the application is relatively mature, and the application of environmental protection and high precision requirements is greatly limited; chemical cleaning method is easy to cause environmental pollution, and the purity produced is also very limited, especially when the dirt composition is complex, it is necessary to use Several cleaning agents need to be re-cleaned to meet the requirements of surface cleanliness; relatively speaking, ultrasonic cleaning has a good cleaning effect, but it is not suitable for sub-micron cleaning. The volume and complexity of the workpiece, the drying of the workpiece after cleaning is also a serious problem.

How laser cleaning works:

Laser cleaning was used to clean ancient buildings and cultural relics in Europe in the early days, but with the systematic development of the industry, its application has gradually expanded to the field of industrial production. The basic principle is to use high-energy high-frequency laser pulses to irradiate the surface of the workpiece, so that the oil stains, rust stains or coatings on the workpiece surface flash, vaporize, and vibrate to achieve high-speed and high-efficiency purposes. Remove surface deposits and surface coatings. At present, laser cleaning has been included in the "Made in China 2025" industry catalog. With the country's increasing emphasis on environmental protection, laser cleaning will open up good development opportunities and broad market prospects.

Benefits of Laser Cleaning Technology:

Compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, hard particle cleaning and high-frequency ultrasonic cleaning, laser cleaning has obvious advantages.

1. Laser cleaning is a "green" cleaning method. It does not use any chemicals and cleaning fluids. The cleaned waste is mainly solid powder, which is small in size and easy to store and recycle. It can easily solve the chemical problem of cleaning tapes. y Environmental pollution problems;

2. The traditional cleaning method is often contact cleaning, which has a mechanical effect on the surface of the cleaned object and damages it.

Benefits of Laser Cleaning:

The surface of the object or the cleaning agent is attached to the surface of the object being cleaned and cannot be removed. Cause secondary pollution, laser cleaning does not require resurfacing, and non-contact solves these problems;

3. The laser can be transmitted through the optical cable, interact with the robotic arm and the robot, can easily perform long-distance operations, can clean the parts that are difficult to reach by traditional methods, and ensure the safety of personnel. in some dangerous places;

4. Laser cleaning can remove various pollutants on the surface of various materials, and achieve the purity that cannot be achieved by conventional cleaning. It can also selectively clean the contaminants on the surface of the material without damaging the surface of the material;

5. Laser cleaning is efficient and time-saving;

6. Although the one-time investment in purchasing a laser cleaning system is high, the cleaning system can be used stably for a long time, with low operating costs and only electricity bills per hour.

Industrial application:

The cleaning objects of laser cleaning include steel, aluminum alloy, titanium alloy, glass and composite materials, etc., and the application fields include aerospace, ships, high-speed rail, automobiles, molds, nuclear power and oceans. Cleaning is easy to cause environmental pollution, and the resulting clean The degree of cleaning is also very limited, especially when the dirt composition is complex, it is necessary to use several cleaning agents to re-clean to meet the requirements of surface cleanliness; relatively speaking, ultrasonic cleaning has a good cleaning effect, but it is not suitable for sub-micron cleaning. , the level of dirt particles can not be cleaned, the size of the cleaning tank limits the volume and complexity of the parts to be processed, and the drying of the workpiece after cleaning is also a serious problem.
