The market prospect of laser cleaning machine is broad, and the application advantages of various industries are obvious
For daily industrial products and professional industrial products, one or several technologies and processes in surface treatment technology are used to realize the functions required by product design or market. In the process of electroplating, phosphating, spraying, welding, packaging and integrated circuit assembly of industrial products, grease, dust, rust, residual solvents, adhesives and other contaminants on the surface must be removed to ensure the quality of the next process. . The current cleaning methods that are widely used in the cleaning industry include mechanical cleaning, chemical cleaning and ultrasonic cleaning, but under the constraints of environmental protection and the requirements of the high-precision market, their applications are greatly limited. The advantages of laser cleaning machines in various industries are obvious.
1. Cleaning of the mold
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.
According to the cleaning test of the intelligent laser cleaning machine of Jinan High Energy Qingyang Laser Cleaning Co., Ltd. on the production line of a tire company in Shandong, it only takes 1.5 hours to clean a set of large truck tire molds online. Compared with conventional cleaning methods, the economic benefits are obvious. At present, many tire factories in the province have introduced the company's intelligent laser cleaning production line.
2. Cleaning of weapons and equipment
Laser cleaning technology is widely used in weapon maintenance. The laser cleaning system can efficiently and quickly remove rust and contaminants, and can select the removal 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 wastes removed by the laser basically do not pollute the environment, and can also be operated remotely, which effectively reduces the health damage to the operators. Jinan Gaoneng Qingyang has been invited to participate in military-civilian integration equipment exchange activities for many times, and its laser cleaning technology has been commended and supported by the Ministry of National Equipment for many times.
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 equipment is 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 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, which 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 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. Pipe cleaning in nuclear power plant reactors
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.
8. Cultural relic cleaning and protection
Internationally, laser cultural relic cleaning and protection technology has been widely used in the cleaning and protection of museum cultural relics and buildings. Many examples prove that laser cleaning is an effective means of cleaning cultural relics and paintings. The mechanism of washing is based on cold ablation by breaking bonds, with little or negligible thermal effect. No thermal damage to the artwork itself.
The above is about the status quo of the laser cleaning industry, and the analysis of the market prospects of laser cleaning machines. Compared with traditional cleaning technology, laser cleaning technology has great advantages in economic benefits, cleaning effects and "green engineering", and has broad advantages. market expectation. With the continuous development of laser cleaning machines to high, precise and sharp aspects, laser cleaning technology will continue to be popularized and applied.
