Secondly, the damage to the substrate during laser cleaning is minimal, which makes it particularly prominent in the cleaning of precision parts. Furthermore, laser cleaning equipment is easy to operate and has high cleaning efficiency. Compared with traditional cleaning methods, it can greatly save time and labor costs. Therefore, when dealing with various oil stains, handheld laser cleaning machines can not only ensure cleaning quality, but also take into account environmental protection and economic benefits, becoming a highlight in the field of modern cleaning.

Laser cleaning technology is an emerging cleaning method that uses high-energy laser beams to effectively remove pollutants on the surface of materials. Compared with traditional cleaning methods, laser cleaning has significant advantages in efficiency, environmental protection and safety.

2.1 Working principle of laser cleaning

The basic working principle of laser cleaning is to use the high energy density of laser and the selective absorption of substances to achieve the removal of surface pollutants. The specific steps are as follows:

Laser irradiation: The beam emitted by the laser is focused on the surface of the object to be cleaned, and its energy density reaches an extremely high level in an instant.

Energy conversion: The photons in the laser beam interact with the molecules on the surface of the pollutant, causing the pollutant to quickly absorb energy and the temperature to rise sharply.

Thermal evaporation and stripping: After reaching a certain temperature, the pollutant begins to evaporate or vaporize, forming gas or dust, which is successfully stripped from the surface of the substrate.

Cleansing completed: After the removal of pollutants is completed, the remaining gas and particles are discharged or collected through appropriate treatment facilities to improve the cleanliness of the working environment.

This method of using laser energy to selectively heat and remove substances makes laser cleaning more flexible and targeted when dealing with different types of pollution.

2.2 Advantages of laser cleaning

Laser cleaning has many advantages, which gradually replace traditional cleaning methods in many industries:

Environmental protection: Laser cleaning does not require the use of chemical cleaning agents, avoiding the application of various harmful chemicals and environmental pollution.

High efficiency: Laser cleaning has a fast reaction speed and can complete the cleaning task in a short time, greatly improving work efficiency.

Strong selectivity: Laser can clean specific materials and pollutants, achieving efficient removal without damaging the substrate.

Wide adaptability: Laser cleaning machines can adjust laser parameters and are suitable for a variety of different materials and pollution conditions, such as metal surfaces.

Reduced post-processing: The reduction of residues after cleaning means a reduction in the demand for post-processing, simplifying the cleaning process.

Safety: The operation process is relatively safe because it does not involve chemicals, reducing the health risks to the operator.

2.3 Application fields of laser cleaning

The wide application of laser cleaning has made it valued in many fields, mainly including the following aspects:

Industrial cleaning: In the automotive manufacturing, aerospace, shipbuilding and other industries, laser cleaning is used to remove oil, rust, welding residues, etc. on the surface of workpieces.

Oil stains can be classified according to their source, composition and properties. The following are three common types of oil stains: engine oil and lubricants, paints and coatings, and industrial oil stains.

1. Engine oil and lubricants

● Features:

Strong viscosity: Engine oil and lubricants usually have high viscosity and can form a thicker oil film on the surface, affecting the efficiency of the cleaning process.

High adhesion: These oil stains have strong adhesion to the substrate and are not easily completely removed by physical or chemical methods.

● Comparison of cleaning difficulty and commonly used cleaning methods:

Cleaning difficulty: Due to viscosity and adhesion, engine oil and lubricants are relatively difficult to clean, and simple water washing or surface wiping is difficult to achieve ideal results.

Common cleaning methods:

Solvent cleaning: Use organic solvents such as gasoline, diesel, etc. for dissolution, which has high cleaning efficiency, but may have certain impacts on the environment and health.

Hot water cleaning: Heat the surface and use a combination of hot water and detergent to remove oil stains. It has strong adaptability but takes a long time.

2. Paint and coating

● Features:

Hard film after drying: Paint and coating form a strong film after drying, which makes it necessary to consider how to avoid damaging the substrate when cleaning.

Surface characteristics: These films have strong adhesion, so specific treatment methods are required when removing them to prevent adverse effects on other surfaces.

● Potential risk of damage to the substrate:

When cleaning paint and coatings, if strong solvents or high temperature treatment are used, the surface of the substrate may be scratched, deformed or peeled, especially on metal and plastic surfaces.

3. Industrial oil pollution

● Features:

Mixed with multiple oil products: Industrial oil pollution is usually a mixture of multiple oil products, dust, metal particles, etc., with complex composition and high difficulty in removal.

Difficult to remove: Due to its diverse composition and high adhesion, industrial oil pollution is easy to cause loss of cleaning materials and reduced cleaning efficiency during the cleaning process.

● Industry application requirements:

In many industries such as manufacturing, mining, metallurgy, etc., industrial oil pollution often occurs in machinery and equipment and working environments. These places need to be cleaned regularly to keep the equipment running normally and extend its service life.

For industrial applications, the choice of cleaning method should not only consider the cleaning effect, but also the cleaning cost and the impact on the environment. Therefore, more and more companies are beginning to use emerging technologies such as laser cleaning to solve industrial oil pollution problems.

Different types of oil pollution have their own characteristics and cleaning difficulties. Understanding this information will help you choose the right cleaning method. In practical applications, it is necessary to comprehensively consider the type of oil pollution, cleaning effect, impact on the substrate, and environmental protection requirements to develop the best cleaning solution. Click here for more information
