Introduction to the use of laser cleaning in various fields:
Laser cleaning technology is a new type of cleaning technology that has developed rapidly in the past 10 years, and it has gradually replaced the traditional cleaning process in many fields with its own advantages and irreplaceability. Laser cleaning can not only be used to clean organic pollutants, but also can be used to clean inorganic substances, including metal corrosion, metal particles, dust and so on. The following describes some practical applications, these technologies have been very mature, has been widely used.

1. Mold cleaning
Every year the world's tire manufacturers to manufacture hundreds of millions of tires, tire molds in the production process must be cleaned quickly and reliably to save downtime. Traditional cleaning methods include sandblasting, ultrasonic or carbon dioxide cleaning, etc., but these methods must usually be in the high heat of the mold after several hours of cooling, and then moved to the cleaning equipment for cleaning, cleaning takes a long time, and easy to damage the accuracy of the mold, chemical solvents and noise will also produce safety and environmental protection and other issues.
The use of laser cleaning method, because the laser can be used to transmit optical fiber, so the use of deep flexibility; because the laser cleaning method can be connected to the fiber optic light guide to the mold's dead corners or not easy to remove the parts of the cleaning, so easy to use; because the rubber is not gasification, so it will not produce toxic gases, affecting the safety of the working environment.
Laser cleaning tire mold technology has been used in a large number of tire industry in Europe and the United States, although the initial investment costs are high, but can save standby time, avoid mold damage, work safety and save raw materials on the gains made by the rapid recovery.
According to the British broad Thai (Quantel) company's LASERLASTE laser cleaning system in Shanghai production line cleaning test shows that it takes only 2 hours to clean a set of large-scale load tire mold online. Compared with conventional cleaning methods, the economic benefits are obvious.

2. Weapons and equipment cleaning
Laser cleaning technology is widely used in weapons maintenance. The use of laser cleaning system, can be efficient, fast removal of rust, pollutants, and can be removed parts of the choice, to realize the automation of cleaning. With laser cleaning, not only the cleanliness is higher than the chemical cleaning process, but also almost no damage to the object surface.
By setting different parameters, it can also form a layer of dense oxide protective film or molten metal layer on the surface of metal objects, improving surface strength and corrosion resistance. Laser removal of waste material on the environment basically does not constitute pollution, but also can be operated at a distance, effectively reducing the operator's health damage.

3. Cleaning of old aircraft paint
In Europe, laser cleaning system has long been used in the aviation industry. The surface of the aircraft after a certain period of time to be repainted, but before painting needs to be completely removed from the original old paint. The traditional mechanical paint removal method is easy to cause damage to the metal surface of the aircraft, bringing hidden danger to the safety of flight. Such as the use of multiple laser cleaning system, can be within two days of an A320 Airbus surface paint layer completely removed, and will not damage to the metal surface.

4. Building wall cleaning
With the rapid development of China's economy, more and more skyscrapers were established, the building's external walls of the cleaning problem is increasingly prominent, the laser cleaning system through the fiber optic cleaning of the building's external walls provides a good solution, it can be a variety of stone, metal, glass on a variety of pollutants for effective cleaning, and more than the conventional cleaning efficiency many times higher. Can also be a variety of stone buildings on the black spot, color spot removal.

5. Cleaning in the electronics industry electronic industry using laser to remove oxides: the electronics industry requires high precision decontamination, especially suitable for the use of laser to remove oxides. In the circuit board before welding, component pins must be thoroughly de-oxidized to ensure optimal electrical contact, in the decontamination process can not damage the pins. Laser cleaning can meet the requirements of use, and high efficiency, a pin only need to irradiate the laser once.

6. Precision instrumentation industry in the precise de-ester cleaning
Precision machinery industry often need to lubricate and anti-corrosion parts used on the ester and mineral oil to remove, usually with chemical methods, and chemical cleaning often still have residues. Laser de-esterification removes esters and mineral oils completely without damaging the surface of the part. The removal of contaminants is accomplished by a shock wave, which is formed by the explosive vaporization of a thin layer of oxides on the surface of the part, resulting in the removal of the contaminants, rather than by mechanical interaction. Thorough de-estering of materials is used for cleaning of mechanical parts in the aerospace industry. Mechanical parts processing oil ester removal can also be used laser cleaning.

7. Nuclear power plant reactor pipe cleaning
Laser cleaning system is also used in nuclear power plant reactor pipe cleaning. It uses optical fiber, high-power laser beam into the reactor inside, directly remove radioactive dust, clean down the material cleanup is convenient. And because it is operated at a distance, it can ensure the safety of the staff.
In summary, laser cleaning plays an important role in many fields, and in automobile manufacturing, semiconductor wafer cleaning, precision parts processing and manufacturing, military equipment cleaning, building wall cleaning, heritage protection, circuit board cleaning, precision parts processing and manufacturing, liquid crystal display cleaning, chewing gum residue removal and other fields can play an important role.
Laser cleaning in the application of national defense and military equipment: such as a variety of aircraft paint and rust, a variety of ships and equipment, a variety of weapons and equipment rust, a variety of combat vehicles and artillery rust, rust, all kinds of parts and so on, the prospects for the development trend of a huge potential. Especially, the advantages of laser cleaning such as environmental protection, convenience, safety, low-cost use are obvious, which is a new, efficient and safe process technology.
