How does the laser clean up?

In industrial production, preservation of cultural relics, and treatment of dental diseases, cleaning techniques are often used. For example: when industrial products are electroplating, phosphating, spraying, welding, packaging and assembly of integrated circuits, in order to ensure the quality of the workpieces in the next process, the grease, dust, rust or residual solvents and stickiness on the surface of the product must be removed. Contaminants such as binders. Due to environmental pollution and poor protection, many cultural relics and artworks are gradually being rusted and defaced. In order to restore the old appearance, it is necessary to clean the dirt and rust on the surface of the cultural relics.

So how does the laser clean?

Laser rust removal: Using the characteristics of laser high energy, high frequency and high power, high energy is instantly deposited in a small area, and high temperature is used to burn the oxide layer, which is also called laser cleaning.

The physical principles can be summarized as follows:

1) The beam emitted by the laser is absorbed by the contamination layer to be treated.
2) Absorption of large energy forms a rapidly expanding plasma, generating shock waves.
3) The shock wave turns the pollutants into fragments and is removed.
4) The light pulse width must be short enough to avoid damage to the surface to be treated by heat accumulation.
The laser can clean the surface of the corroded workpiece with a high-energy beam, which is similar to a small explosion on the surface of the workpiece. The stains and rust on the surface become gas and dust and are adsorbed away, and the substrate of the workpiece is not harmed to maintain its original Low temperature!

Advantages of laser cleaning technology
Because laser cleaning does not use any chemical solvents or other consumables, it is environmentally friendly, safe to operate, and has many advantages:

•Environmental protection, no need to use any chemicals and cleaning fluid(Laser cleaning equipment on sales)
• Cleaning waste is mainly solid powder, small in size and easy to collect and recycle
•Cleaning waste smoke is easy to absorb and process, low noise, no harm to human health
•Non-contact cleaning, no medium residue, no secondary pollution
•Can achieve selective cleaning without damaging the substrate
• No working medium consumption, only electricity consumption, low use and maintenance costs
•Easy to realize automation and reduce labor intensity
•Suitable for hard-to-reach areas or surfaces, suitable for hazardous or hazardous environments
