Laser cleaning machine is a new generation of high-tech products for surface treatment, which is green and environmentally friendly. It can evaporate or peel off the dirt, rust or coating on the surface of materials, and effectively remove the attachments or surface coatings on the surface of cleaning objects at high speed.
Laser cleaning technology is known as the most potential green cleaning technology in the 21st century, which has great advantages over traditional cleaning methods. Laser cleaning system is making great strides towards practical application. Up to now, laser cleaning system has been able to stably and effectively clean various regular substrate surfaces. The materials that can be cleaned include but are not limited to metal, alloy, glass and various composite materials.
Advantages of Laser Cleaning Machine
a.Green and environmental protection. Laser cleaning and laser rust removal does not need to use chemicals, and will not produce waste liquid to pollute water;
b.The damage to the substrate is small. There is no need to contact the substrate or apply any mechanical force to the substrate;
c.With a high degree of flexibility. Facilitate automation;
d.Excellent cleaning effect. Selecting fiber lasers with different wavelengths and processing parameters can easily clean various pollutants attached to the substrate surface;
e.The cleaning efficiency is high. Laser rust removal using scanning technology can convert point light source into line or surface light source, which forms a cleaning speed much higher than that of traditional cleaning technology.
Principle of Laser Cleaning
The laser cleaning and laser rust removal process is actually a process of interaction between laser and matter, including a series of complex chemical and physical effects.
Laser cleaning is actually to use the characteristics of high brightness of laser to destroy these forces between pollutants and objects without damaging the objects themselves. Because of the complex composition and structure of pollutants, the mechanism of laser interaction is also different. Scientists have proposed various theoretical models to explain this. The most common explanations are as follows:
a.The laser can achieve a high concentration of energy in time and space. The focused laser beam can produce a high temperature of thousands or even tens of thousands of degrees near the focus, which makes the dirt evaporate, vaporize or decompose instantaneously.
b.The divergence angle of the laser beam is small and the directivity is good. The laser beam can be converged into spots of different diameters through the condensing system. Under the condition of the same laser energy, controlling the laser beam spots with different diameters can adjust the energy density of the laser and make the dirt expand by heating. When the expansion force of the dirt is greater than the adsorption force of the dirt on the substrate, the dirt will leave the surface of the object.
c.The laser beam can generate ultrasonic waves on the solid surface, generate mechanical resonance, and break and fall off the dirt.

Application of Laser Cleaning Machine
In the application field, laser cleaning is an efficient, portable and suitable for various industries, and is the most economical cleaning technology among all industrial cleaning methods at present. Laser cleaning machine was first started in the microelectronics industry to meet the need to remove micro particles from the memory template in industrial production.
Nowadays, laser cleaning system has been involved in various production fields, such as the cleaning of the oxide layer or rubber on the mold surface. Many researchers have invested a lot of experimental research work and achieved ideal cleaning results.
How to effectively remove metal surface paint is also a common problem in production. Some people have used laser cleaning technology to carry out experimental research on steel surface paint removal. The results show that laser cleaning machine has great potential value and will probably replace traditional paint removal methods.
In addition, the research of laser cleaning in other aspects has also achieved good results, including cultural relics and artworks, optical components, etc.
Development of Laser Cleaning Machine
Laser cleaning and laser rust removal is a new cleaning technology developed rapidly in recent ten years. It is gradually replacing the traditional surface treatment cleaning process in many fields because of its many advantages. It can adapt to the cleaning of various surface contaminants, has little environmental pollution, and does not damage the substrate.
At present, this method has become the supplement and extension of the traditional cleaning method, and has shown a broad application prospect because of its inherent advantages. In general, compared with other laser processing technologies, laser cleaning has developed rapidly in theoretical research and application fields.
Limited by the process theory research and equipment development technology, laser cleaning technology has not really replaced the traditional cleaning method. However, with the in-depth exploration of more and more researchers, this technology will be developed and popularized faster.
The remarkable advantages and broad application prospects of laser cleaning and laser rust removal technology are worthy of our investment in manpower and material resources. In-depth research and exploration of this technology and development of new practical equipment are of great significance to the reform of existing industrial cleaning and environmental protection.
