Laser Cleaning: Advantages and Applications of Laser Cleaning
Comparison of advantages of laser cleaning
1. Environmental advantages
Laser cleaning is a "green" cleaning method. It does not need to use any chemicals and cleaning fluids. The waste materials cleaned are basically solid powders, which are small in size, easy to store, recyclable, and have no photochemical reaction and no pollution. . It can easily solve the environmental pollution problem caused by chemical cleaning. Often an exhaust fan can solve the problem of waste generated by cleaning.
2. Effect advantage
The traditional cleaning method is often contact cleaning, which has mechanical force on the surface of the cleaned object, damages the surface of the object or the cleaning medium adheres to the surface of the cleaned object, which cannot be removed, resulting in secondary pollution. Laser cleaning is non-abrasive and non-toxic. Contact, non-thermal effect will not damage the substrate, so that these problems are easily solved.
3. Control advantage
The laser can be transmitted through the optical fiber, cooperate with the manipulator and the robot, conveniently realize the long-distance operation, and can clean the parts that are difficult to reach by the traditional method, which can ensure the safety of personnel in some dangerous places.
4. Convenient advantages
Laser cleaning can remove various types of pollutants on the surface of various materials, achieving a cleanliness that cannot be achieved by conventional cleaning. Moreover, the pollutants on the surface of the material can be selectively cleaned without damaging the surface of the material.
5. Cost advantage
The laser cleaning speed is fast, the efficiency is high, and time is saved; although the one-time investment in the initial stage of purchasing a laser cleaning system is high, the cleaning system can be used stably for a long time, with low operating costs, and more importantly, it can easily realize automatic operation.
Laser cleaning application
As a new cleaning technology, laser cleaning has many advantages such as environmental protection and high efficiency. It is one of the main development directions of laser technology today and has a wide range of application prospects. , electronics industry, medical treatment and restoration of cultural relics have been well applied.
