Every year, tire manufacturers around the world produce hundreds of millions of tires. In the production process, the tire mold must be cleaned quickly and reliably to save downtime. Traditional cleaning methods include sand blasting, ultrasonic or carbon dioxide cleaning, but these methods usually have to be transferred to the CL-300 laser cleaning machine for cleaning after the hot mold has cooled for several hours. Cleaning time is long, easy to damage the precision of the mold, chemical solvents and noise can also cause safety and environmental problems. Using laser cleaning machine method, because the laser can be transmitted through optical fiber, so it is very flexible to use; Because the laser cleaning method can be connected through optical fiber, the light can be directed to the dead corner of the mold or the parts that are difficult to clean, it is very convenient to use; Not gasified, so it will not produce toxic gases, affecting the safety of the working environment. Laser cleaning tire die technology has been widely used in European and American tire industry. Although the initial investment cost is high, the benefits obtained from saving standby time, avoiding mold damage, safe production, saving raw materials and other aspects can be quickly recovered. According to the cleaning test of Quancel laser cleaning system on the production line of Shanghai Shuangqian Truck Tire Co., Ltd., on-line cleaning of a large truck tire mould took only 2 hours. Compared with the conventional cleaning method, the economic benefit is obvious.
The anti-viscoelastic film on molds in the food industry needs to be replaced regularly to ensure hygiene, and laser cleaning without chemical reagents is particularly suitable for this application.
Laser cleaning technology has been widely used in weapon maintenance. The laser cleaning system can efficiently and quickly remove rust and contaminants, and can choose the cleaning parts, and realize the automation of cleaning. Using laser cleaning, not only cleanliness is higher than the chemical cleaning process, and almost no damage to the surface of the object. By setting different parameters, Quantel's Laserlaste can also form a dense oxide protective film or metal melting layer on the surface of metal objects to improve the surface strength and corrosion resistance. The laser removed waste basically does not constitute pollution to the environment, but also can be operated from a distance, effectively reducing the damage to the operator's health.
Aircraft old paint removal:
European laser cleaning systems have long been used in the aerospace industry. The surface of the aircraft must be repainted after a certain period of time, but the original old paint needs to be completely removed before painting. The traditional method of mechanical paint removal is easy to damage the metal surface of aircraft, which brings hidden danger to the safety of flight. If multiple laser cleaning systems are used, the paint layer on the surface of an A320 Airbus aircraft can be completely removed in two days without damaging the metal surface.
Building exterior wall cleaning:
With the rapid development of China's economy, more and more skyscrapers are being built, and the problem of exterior wall cleaning is becoming more and more prominent. The LASERLASTE laser cleaning system can clean the exterior walls of buildings well through optical fiber. The maximum length of the solution is 70 meters, which can effectively clean various pollutants on various stones, metals and glass, and its efficiency is many times higher than that of conventional cleaning. It can also remove black spots and stains from various stones in buildings. The laser cleaning system has been used to clean the buildings and steles of Shaolin Temple in Songshan Mountain. The results show that the laser cleaning system is effective in protecting the appearance of ancient buildings.
Cleanliness in the electronics industry
The electronics industry uses lasers to remove oxides: The electronics industry needs high-precision decontamination, and laser oxidation is especially suitable. Prior to soldering the board, component pins must be thoroughly deoxidized to ensure optimal electrical contact, and pins must not be damaged during the decontamination process. Laser cleaning can meet the requirements of use, and the efficiency is very high, each needle only need laser irradiation once.
Precision machinery industry in the precise deester cleaning:
The precision machinery industry often needs to remove esters and mineral oils used to lubricate and corrosion-resistant parts, often using chemical methods, and chemical cleaning often still leaves residues. Laser deesterification can completely remove esters and mineral oils without damaging the surface of parts. The removal of contaminants is accomplished by shockwaves, which are formed by the explosive vaporization of a thin oxide layer on the surface of the part to remove dirt, rather than by mechanical interaction. The material is completely deesterified and is used for cleaning machine parts in the aerospace industry. The removal of oil esters during machining of mechanical parts can also be cleaned by laser.
Nuclear power plant reactor pipe cleaning:
Laser cleaning systems are also used to clean reactor pipes in nuclear power plants. It uses fiber optics to direct a high-power laser beam into the reactor to remove radioactive dust directly, making the cleaned material easier to clean. And because it is a remote operation, can ensure the safety of staff.
Above all, laser cleaning in automobile manufacturing, semiconductor wafer cleaning, precision parts processing and manufacturing, military equipment cleaning, building external wall cleaning, protection of cultural relics, circuit board cleaning, precision parts processing and manufacturing, and other fields play an important role, LCD cleaning, gum residue removal can play an important role in areas such as.
