Laser cleaning technology is the process of using laser beam to irradiate the surface of the workpiece to peel off or vaporize the dirt and rust coating on the surface, so as to clean the surface of the workpiece to achieve the purpose. What is recognized is the thermal effect and vibration effect of laser.
Laser cleaning as a new cleaning technology, laser cleaning has many advantages, such as environmental protection, high efficiency and so on. It is one of the main development directions of laser technology, and has a wide application prospect. It has been well applied in aerospace, shipbuilding, rail transit, automobile manufacturing, steel manufacturing, electronic industry, medical treatment and cultural relic restoration.
Advantages of laser cleaning
Compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, liquid solid strong impact cleaning and high frequency ultrasonic cleaning, laser cleaning has obvious advantages.
1.Laser cleaning is a kind of "green" cleaning method. It doesn't need any chemical agents and cleaning liquid. The waste material is solid powder, small in volume, easy to store and recyclable. It can easily solve the environmental pollution problem caused by chemical cleaning;
2.The traditional cleaning method is often contact cleaning, which has mechanical force on the surface of the object to be cleaned, which damages the surface of the object or the cleaning medium adheres to the surface of the object to be cleaned, which can not be removed, resulting in secondary pollution;
3. Laser can be transmitted through optical fiber, cooperate with robot hand and robot to realize remote operation conveniently. It can clean the parts that are not easy to reach by traditional methods, which can ensure the safety of personnel when used in some dangerous places;
4.Laser cleaning can remove all kinds of pollutants on the surface of all kinds of materials, which can not be achieved by conventional cleaning. Moreover, the pollutants on the material surface can be selectively cleaned without damaging the material surface;
5. High efficiency of laser cleaning and time saving;
6.Although the initial one-time investment of laser cleaning system is high, the cleaning system can be used stably for a long time with low operating cost. More importantly, it can realize automatic operation conveniently.
