Laser cleaning technology is a new cleaning technology that has developed rapidly in the past 10 years. It has gradually replaced traditional cleaning processes in many fields with its own advantages and irreplaceability. Laser cleaning can be used not only to clean organic pollutants, but also to clean inorganic substances, including metal rust, metal particles, dust, etc. Some practical applications are described below. These technologies are very mature and widely used.
Tire manufacturers around the world manufacture hundreds of millions of tires every year, and the cleaning of tire molds during the production process must be fast and reliable to save downtime. Traditional cleaning methods include sandblasting, ultrasonic or carbon dioxide cleaning, etc., but these methods usually have to be moved to the cleaning equipment after the high-heat mold is cooled for several hours, which takes a long time and easily damages the accuracy of the mold. , chemical solvents and noise will also cause problems such as safety and environmental protection.
Using the laser cleaning method, because the laser can be transmitted by the optical fiber, it is very flexible in use; because the laser cleaning method can be connected with the optical fiber to guide the light to the dead corner of the mold or the parts that are not easy to be cleaned, so it is easy to use; No gasification, so no toxic gas will be produced, which will affect the safety of the working environment.
The technology of laser cleaning tire molds has been widely used in the tire industry in Europe and the United States. Although the initial investment cost is high, the benefits obtained in saving standby time, avoiding mold damage, working safety and saving raw materials can be quickly recovered.
Just as with cleaning metals, laser ablation for ceramics works by irradiating the surface contaminants with thousands of laser pulses per second. The process is safe for the substrate ceramic layer and creates little waste — which is typically captured by the laser’s built-in suction nozzle.
As with any laser cleaning application, the key to success for ceramic cleaning is a properly calibrated laser solution. You want a laser system that can reach the ablation threshold necessary for cleaning the contaminant layers without damaging the products you’re cleaning. Therefore, choosing a laser with the right power level, settings, optics, and delivery system is critical. Thankfully, our laser experts have the knowledge to ensure you always have the right laser for the job.
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. Using multiple laser cleaning systems, the paint can be completely removed from an A320 Airbus within two days without damaging the metal surface.
4. Cleaning of building exterior walls
With the rapid development of our country’s economy, more and more skyscrapers have been built, and the problem of cleaning the exterior walls of buildings has become increasingly prominent. The laser cleaning system provides a good solution for cleaning the exterior walls of buildings through optical fibers. It can It can effectively clean various pollutants on various stone, metal and glass, and the efficiency is many times higher than that of conventional cleaning. It can also remove black spots and stains on various stone materials of buildings.
5.Cleaning in the electronics industry The electronics industry uses lasers to remove oxides:
The electronics industry requires high-precision decontamination, and is especially suitable for laser deoxidation. Component pins must be thoroughly deoxidized before board soldering to ensure optimal electrical contact without damaging the pins during the decontamination process. Laser cleaning can meet the requirements of use, and the efficiency is very high, and only one pin needs to be irradiated with the laser.
6. Precise deesterification cleaning in the precision instrument industry
The precision machinery industry often needs to remove esters and mineral oils used for lubrication and corrosion resistance on parts, usually chemically, and chemical cleaning often leaves residues. Laser deesterification can completely remove esters and mineral oils without damaging the surface of the parts. The removal of contaminants is accomplished by shock waves, which are formed by the explosive gasification of the thin oxide layer on the surface of the parts, resulting in contaminant removal rather than mechanical interaction. The material is thoroughly deesterified for the cleaning of mechanical parts in the aerospace industry. Laser cleaning can also be used for oil and ester removal in the machining of mechanical parts.
7. Nuclear power plant reactor pipe cleaning
Laser cleaning systems are also used in the cleaning of pipelines 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 from a distance, the safety of the staff can be ensured.
To sum up, laser cleaning plays an important role in many fields, and is used in automobile manufacturing, semiconductor wafer cleaning, precision parts processing and manufacturing, military equipment cleaning, building exterior wall cleaning, cultural relics 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.
The application of laser cleaning in national defense and military equipment: such as paint stripping and rust removal of various aircraft, various ship equipment, various weapon equipment rust removal, various chariot and artillery rust removal, various parts rust removal, etc., with broad prospects , the development trend has great potential. In particular, laser cleaning has obvious advantages such as environmental protection, convenience, safety, and low-cost use. It is a new, efficient and safe process technology.
