There are various cleaning methods for traditional cleaning industrial equipment, most of which are chemical agents and mechanical methods. Today, with the increasingly stringent requirements of environmental protection laws and regulations and the increasing awareness of environmental protection and safety, the types of chemicals that can be used in industrial production cleaning will become less and less. Laser cleaning machine has the characteristics of no grinding, non-contact, low thermal effect and suitable for objects of various materials.
Among the contaminants on the workpiece surface, the combination between the attachment on the workpiece surface and the surface is mainly due to the following forces. Among them, capillary force, adsorption force and electrostatic force are the most difficult to destroy, so the laser cleaning machine needs to overcome these forces. The smaller the size of particles, the greater the acceleration required to remove them, which is why it is difficult to remove the attachments on the surface of objects with small diameter by conventional cleaning technology.
The research and development of laser cleaning machine technology and equipment in China started late, basically tracking the development of foreign countries. Although some achievements have been achieved in a relatively short time, there is a significant gap compared with foreign countries. Therefore, there are not many mature laser cleaning equipment in China, and improving cleaning efficiency and stability is also very important.
The research of laser cleaning machine technology started in the mid-1980s, but it did not really enter industrial production until the early 1990s. It gradually replaces the traditional cleaning method in many occasions. The decontamination range of foreign laser cleaning machines is very wide, from the thick rust layer to the fine particles on the laser surface can be removed. In the decontamination process, there are many types of equipment used in the laser cleaning experiment, and the wavelength range of the laser used is wide, but the development of laser cleaning machine technology is uneven, some have taken the lead in realizing industrialization, while some are still in the laboratory stage.
The emergence of laser cleaning machine technology has opened up a new field of laser technology in industrial application, and the matching laser cleaning equipment has been developed using the existing laser technology conditions in China. And make it practical in a short time. Industrialization. It is completely possible, and it is also of great significance to promote the development of high-tech industries.
