Comparison of laser cleaning and traditional cleaning

Apr 24,2023 | TOPTEK

Although traditional cleaning can also clean the surface of workpieces to a certain extent, as environmental regulations become more and more stringent today, traditional cleaning is gradually being eliminated.

The main problems with traditional cleaning methods include:
1. Negative impact on the environment and wear on the substrate.
2. The shot blasting system produces a large amount of waste, which will damage the fine surface of the substrate.
3. Cleaning with chemical solvents will generate potentially dangerous vapors and waste liquids.

Advantages of laser cleaning:
1. More environmentally friendly: No need to use any chemicals and cleaning fluids. The waste after cleaning is basically solid powder, small in size, easy to store, recyclable, free of photochemical reaction and pollution-free.

2. Good effect: Laser cleaning has no grinding, non-contact and no thermal effect. It will not generate mechanical force on the object to be cleaned, will not damage the surface of the object, will not damage the substrate, and will not produce secondary pollution.

3. Easy to control: The laser can be transmitted through optical fiber, and cooperate with the robot to realize long-distance operation, and can clean complex structural parts that are difficult to reach by traditional methods. This feature also makes the safety of operators in some dangerous places more secure.

4. Wide range of uses: laser cleaning can remove various pollutants on the surface of various materials, and achieve a cleanliness that cannot be achieved by conventional cleaning. Moreover, contaminants on the surface of the material can be selectively cleaned without damaging the surface of the material.

5. Low cost: The initial investment of the laser cleaning system is high, but it can be used stably for a long time. The service life is up to 10 years. Costs are lower than traditional cleaning methods.

The shortcomings of traditional cleaning methods such as high labor intensity, low efficiency, low safety factor, and high cost, as well as the shortcomings of traditional cleaning methods, have prompted the application of laser technology in the field of surface cleaning. Due to its many advantages, laser cleaning is now the most effective method of removing unwanted substances from material surfaces.
