A laser irradiating the surface of the object to be cleaned can produce at least three effects.
The principle and advantages of laser cleaning machine are as follows:
01
Thermal expansion effect
The difference between the absorption coefficient of a certain wavelength of laser energy between the substrate and the surface contaminants. Its purpose is to make the substrate and surface dirt absorb energy to produce thermal expansion. When the expansion force of the dirt is greater than the adsorption force of the dirt on the substrate, dirt will separate from the surface of the object.
02
Molecular photolysis or phase change
The laser can achieve high energy concentration in time and space. The focused laser beam can generate thousands of degrees or even tens of thousands of degrees near the focal point. It causes the dust to evaporate, vaporize or decompose immediately.
03
The vibration of laser pulse
The surface to be cleaned is irradiated with a high-frequency pulsed laser. The laser beam can generate ultrasonic vibration on the solid surface, thereby generating mechanical resonance, thereby vibrating the dirt layer or condensate.
Advantages of laser cleaning machine
01 More environmentally friendly
No need to use any chemicals and cleaning fluids. Cleaning waste is basically a solid powder, small in size, easy to store, recyclable, no photochemical reaction, no pollution.
02 Good effect
No abrasives, no contact, no thermal effect of laser cleaning, mechanical force on the object being cleaned, damage to the surface of the object, damage to the substrate, no secondary generation.
03 Easy to control
The laser can be transmitted through optical fiber, can cooperate with the robot to realize long-distance operation, and can clean complex structural parts that are difficult to reach by traditional methods. This function can also make operators safer in certain hazardous locations.
04 Widely used
Laser cleaning can remove various contaminants on the surface of various materials to achieve a cleanliness level that cannot be achieved by traditional cleaning. It can also selectively clean contaminants on the surface of the material without damaging the surface material.
05 Low cost
The initial investment of the laser cleaning system is very high, but it can be used stably for a long time with a service life of up to 10 years: low operating cost, fast speed, high efficiency, time-saving, and quick return on investment. In the long run, the cost is lower than traditional cleaning methods.
