Laser cleaning is to irradiate workpieces with high-energy laser beams. It is a non-contact cleaning method. The beam is adjustable to ensure the accuracy of workpieces after cleaning. Traditional cleaning uses chemical agents and mechanical methods for cleaning, which causes great environmental pollution. Operators Security cannot be guaranteed. Laser cleaning can effectively remove organic and inorganic pollutants, including metal rust, oil stains, paint coatings, etc.

At present, laser cleaning technology is very mature and widely used in the following industries

1. Mold cleaning

Mold Cleaning Traditional cleaning methods include sandblasting, ultrasonic or carbon dioxide cleaning, etc. Traditional cleaning uses chemical solvents, heats through high heat, and then cools down before cleaning, which takes a long time and damages the precision of the original mold.

The laser cleaning method can be connected with an optical fiber to guide the light to the dead corner of the mold or the part that is difficult to clean for cleaning. The technology of laser cleaning tire molds has been widely adopted in the tire industry in Europe and America. Although the initial investment cost is high, it can save standby time. Gains in time, avoidance of mold damage, work safety and savings in raw materials pay off quickly. Compared with conventional cleaning methods, the economic benefits are obvious.

2. Cleaning of weapons and equipment

Laser cleaning technology is widely used in weapon maintenance. The laser cleaning system can remove rust and pollutants efficiently and quickly, and can select the cleaning part to realize the automation of cleaning. Using laser cleaning, not only the cleanliness is higher than the chemical cleaning process, but also has almost no damage to the surface of the object. By setting different parameters, a dense oxide protective film or metal melting layer can also be formed on the surface of the metal object to improve the surface strength and corrosion resistance. The waste material removed by the laser basically does not pollute the environment, and it can also be operated remotely, which effectively reduces the health damage to the operators.

3. Cleaning of old aircraft paint

Laser cleaning systems have long been used in the aviation industry in Europe. The surface of the aircraft needs to be repainted after a certain period of time, but the original old paint needs to be completely removed before painting. The traditional mechanical paint removal method is easy to cause damage to the metal surface of the aircraft, which brings hidden dangers to safe flight. If multiple laser cleaning systems are used, the paint layer on the surface of an A320 Airbus can be completely removed within two days without damaging the metal surface.

4. Cleaning of building exterior walls

With the development of the economy, the number of high-rise buildings is increasing day by day. The traditional exterior wall cleaning method is inefficient and can no longer meet the demand. Laser cleaning provides a good solution for cleaning the exterior walls of buildings. It can clean all kinds of stone, metal, Various pollutants on the glass can be effectively cleaned, and the efficiency is many times higher than that of conventional cleaning. Laser cleaning machines are used to clean black spots and stains on various stone materials such as buildings and steles, which can restore the appearance of ancient buildings. very good.

5. Cleaning in the electronics industry

The electronics industry uses lasers to remove oxides: The electronics industry requires high-precision decontamination, and it is especially suitable for lasers to remove oxides. Before the circuit board is soldered, the component pins must be completely deoxidized to ensure the best electrical contact, and the pins must not be damaged during the decontamination process. Laser cleaning can meet the requirements of use, and the efficiency is very high. One stitch only needs to be irradiated with laser once.

6. Cleaning in precision machinery industry

The precision machinery industry often needs to remove esters and mineral oils used for lubrication and anti-corrosion on parts, and chemical cleaning often still has residues. Laser deesterification can remove esters and mineral oil without mechanical contact and without damaging the surface of parts. Laser cleaning has been widely used in the removal of oil and ester in the processing of mechanical parts.

7. Pipeline cleaning in nuclear power plant reactor

Laser cleaning systems are also used in the cleaning of pipes in nuclear power plant reactors. It uses optical fibers to introduce high-power laser beams into the reactor to directly remove radioactive dust, and the cleaned materials are easy to clean. And because it is operated remotely, the safety of the staff can be ensured.

Laser cleaning plays an important role in many industries. Its advantages of environmental protection, high efficiency, safety, and low cost of use have been reflected in many fields. It is a new technology with great development potential.
