What is the Fiber Laser Cleaning
First, let’s take a look at what is laser cleaning
Laser cleaning is a green, non-destructive surface cleaning technology that uses the interaction of laser and material to remove attachments on the surface of the substrate. Simply put, the laser fiber laser cleaning machine is to use the laser beam’s high energy density, controllable direction, and strong convergence ability to destroy the bonding force between the pollutant and the substrate or directly vaporize the pollutant for decontamination. , Reduce the bonding strength of the pollutants and the matrix, and then achieve the effect of cleaning the surface of the workpiece.
Traditional cleaning mostly uses chemical agents or mechanical methods. With the advancement of science and technology, people’s awareness of environmental protection is getting stronger and stronger, and traditional cleaning methods can no longer meet people’s needs. However, the fiber laser cleaning machine has non-abrasive, non-contact, and non-thermal cleaning characteristics. It is suitable for objects of various materials and is considered to be the most reliable and effective solution. In the future, it will gradually replace traditional cleaning methods.
So, what are the advantages of fiber laser cleaning machine compared with traditional cleaning machine?
Advantages of Fiber Laser Cleaning Machine
1. The fiber laser cleaning machine is more “green” and environmentally friendly
The fiber laser cleaning machine is a “green” cleaning machine. There is no need to use any chemicals and cleaning fluid, and the waste after cleaning is basically + solid powder, small in size, easy to store, recyclable, and basically not polluting the environment. And, a non-contact cleaning method.However, most of the traditional cleaning methods are contact cleaning, which generates mechanical force on the surface of the cleaning object, damages the surface of the object or the cleaning medium adheres to the surface of the object to be cleaned, and cannot be removed, causing secondary pollution.
2. The fiber laser cleaning machine is cleaner and more efficient
The industrial laser cleaning machine can remove all kinds of pollutants on the surface of various materials, clean evenly, with high cleanliness, and the cleanliness is much higher than that of chemical cleaning processes. Laser cleaning can effectively purify the surface without damaging the substrate by adjusting the laser process parameters.However, the traditional cleaning method has good cleaning effect and average efficiency. Chemical cleaning and mechanical polishing will cause uneven cleaning and cause certain damage to the workpiece.
3. Laser cleaning operation is simpler
The laser cleaning operation is simple, can be easily automated operation, and the handheld device is very flexible. The laser can be transmitted through optical fiber, and it can easily realize remote operation with robots and robots, and can clean the parts that are not easily reachable by traditional methods. This can ensure the safety of personnel when used in some hazardous locations.However, the chemical cleaning and mechanical friction cleaning processes are more complicated and require safety protection measures. Although ultrasonic cleaning is simple to operate, it also requires manual addition of consumables.
4. Low cost of laser cleaning machine
The first purchase cost of laser cleaning is high, but no consumables are needed, and the maintenance cost is low. It only needs power.Traditional cleaning equipment, although the initial purchase of the machine is lower than the laser cleaning, but the later maintenance cost is good, especially the high cost of consumables.
Classification of Fiber laser cleaning machine
There are many types of industrial laser cleaning machines that can be cleaned, and there are many laser cleaning methods. For different metal materials and different stains, different laser cleaning methods can be selected according to the actual situation.
The working principle of the industrial laser cleaning machine can be summarized in four aspects: laser vaporization decomposition, laser peeling, thermal expansion of dirt particles, substrate surface vibration and particle vibration; and laser cleaning is often the result of multiple mechanisms acting simultaneously.
1. Laser dry cleaning method:
That is, the pulsed laser is used for direct radiation purification. The laser light generated by the laser can be condensed by the optical system to achieve a high degree of energy concentration. The focused laser beam can produce thousands or even tens of thousands of degrees near the focal point, instantly evaporating or decomposing the attachments on the surface of the object.
2. Laser + liquid film method:
That is, a layer of liquid film is deposited on the surface of the assembly first, and then the liquid film is blasted and purified by laser.
3. Laser + inert gas method
That is, after the laser irradiates the surface of the workpiece, the dirt is peeled from the surface, and the dirt is blown away with inert gas to avoid re-contamination and oxidation of the cleaned surface.
4.First irradiate the surface of the workpiece with a laser, and then use a non-corrosive chemical method for decontamination after the dirt is loose. Only works of art use this method.
At present, the first three cleaning methods are mainly used in industrial production, among which the laser dry cleaning method and the laser + liquid film cleaning method are used more.
