With the improvement of industrial automation and environmental awareness, laser cleaning technology has gradually become a popular choice for cleaning solutions in various industries. Laser cleaning, as an efficient and environmentally friendly surface treatment method, can accurately remove oil, oxides and pollutants from the surface of metals, plastics and other materials. It is widely used in mold cleaning, welding surface treatment, mechanical maintenance and other fields. This technology not only improves work efficiency, but also reduces dependence on chemical cleaning agents, thereby reducing harm to the environment and human body.

However, although laser cleaning has many advantages, its operation process also hides certain safety risks. The laser beam itself has a high energy density. If you don't pay attention, it may cause eye damage or skin burns to the operator. In addition, the smoke and harmful gases generated during laser cleaning also need to be properly handled. Therefore, when implementing laser cleaning operations, ensuring safety is the top priority. Establishing strict safety procedures and training mechanisms, protecting the safety of operators, and maintaining the health of the working environment are all responsibilities that cannot be ignored by every company using laser cleaning technology.

Basic Principles of Laser Cleaning

Laser cleaning is an advanced surface treatment technology that removes contaminants (such as oil, rust, dirt, etc.) through a high-energy laser beam.

1. Working mechanism of laser

Laser cleaning uses a focused high-energy laser beam to irradiate the surface to be cleaned. After the laser beam is focused by a special optical system, it can produce a high-intensity energy density. This high-energy laser beam will quickly heat the contaminants on the surface and evaporate or decompose in a very short time.

2. The interaction principle between laser and oil

Absorption and reflection:

Oil usually has a high black or dark color characteristic, so it can effectively absorb the energy of the laser beam. Metals and other substrates reflect part of the laser energy, which means that there is no excessive energy loss during the cleaning process.

Rapid heating:

After the laser is irradiated on the surface of the oil, the temperature of the oil rises rapidly. When a certain temperature is reached, the oil will undergo thermal decomposition or vaporization to form gas and small particles (smoke). This process is very fast, usually completed within nanoseconds to microseconds.

Stripping and impact:

Under the action of the laser, the generated gas and steam will form an instantaneous pressure wave, which can effectively strip the oil. This stripping depends not only on heat (for example, the effect of steam pressure), but also on the direct impact of the laser on the oil.

3. Effect and application

Through the above interaction, laser cleaning can effectively remove different types of oil and impurities without damaging the substrate. The advantages of this process are its good cleaning effect, high selectivity, and precise control of the depth and range of cleaning. Therefore, laser cleaning technology has been widely used in industrial cleaning, maintenance and repair, and has become an important means of modern surface treatment.
