Laser cleaning technology is a new type of 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 contaminants, but also to clean inorganic materials, including metal rust, metal particles, dust, etc. Here are some practical applications. These technologies are very mature and have been widely used.
Every year, tire manufacturers around the world manufacture hundreds of millions of tires. The cleaning of tire molds must be fast and reliable during production to save downtime. Conventional cleaning methods include sand blasting, ultrasonic or carbon dioxide cleaning, but these methods usually have to be cooled in a hot mold for several hours, then moved to a cleaning device for cleaning, which takes a long time to clean and easily impairs the accuracy of the mold. Chemical solvents and noise can also cause safety and environmental issues.
The laser cleaning method is very flexible in use because the laser can be transmitted by using an optical fiber; since the laser cleaning method can use optical fiber connection to clean the light guide to a dead angle of the mold or a portion that is difficult to remove, it is convenient to use; No gasification, so no toxic gases 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 by saving standby time, avoiding mold damage, working safety and saving raw materials can be quickly recovered.
According to the cleaning test conducted by MRJ-laser cleaning system on the production line of Shanghai Shuangqian Heavy Duty Truck Co., the mold of a large truck tire can be cleaned online in just 2 hours. The economic benefits are obvious compared to conventional cleaning methods.
Laser cleaning technology is widely used in weapon maintenance. The laser cleaning system can remove rust and contaminants efficiently and quickly, and can select the cleaning parts to realize the automation of cleaning. Laser cleaning is not only more clean than chemical cleaning, but also has no damage to the surface of the object.
By setting different parameters, a dense oxide protective film or metal molten layer can be formed on the surface of the metal object to improve surface strength and corrosion resistance. The laser-cleared waste does not substantially pollute the environment, and can also be operated remotely, effectively reducing the health damage to the operator.
Aircraft old paint cleaning
Laser cleaning systems in Europe 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 must be completely removed before painting. The traditional mechanical paint removal method is easy to cause damage to the metal surface of the aircraft, posing a hidden danger to safe flight. If multiple laser cleaning systems are used, the paint on the surface of an A320 Airbus can be completely removed within two days without damaging the metal surface.
