The difference between traditional cleaning and laser cleaning
Traditional cleaning
High efficiency, no damage to the surface
No pressure cleaning, heavy pollution, cumbersome waste disposal
High flexibility, high cost, damage to the surface, heavy workload for waste disposal
The cleaning efficiency is high, and the size of the cleaning product is limited. After cleaning, it needs to be dried before use.
High cleaning efficiency, no occupational hazards, no pollution, not easy to damage the substrate, no size limit
Principles and Advantages of Laser Cleaning
Principles
Laser cleaning employs high-frequency and high-energy laser pulses to irradiate the surface of a workpiece. By instantaneously absorbing the focused laser energy, the coating layer causes the surface oil, rust, or coating to rapidly vaporize or peel off. This technique proves to be an efficient and expeditious method for eliminating surface attachments or coatings. Thanks to the short duration of laser pulses and appropriate parameters, the metal substrate remains undamaged.
Advantages
Laser cleaning offers numerous advantages such as contactless operation, absence of grinding or pollution, noiselessness, and the elimination of consumables. It minimizes surface damage and saves energy. Moreover, it can remove pollution particles at a sub-nanometer level, ensuring high cleanliness. The process is emission-free and can be remotely operated, making it suitable for cleaning hard-to-reach areas. It excels at quickly cleaning heavily contaminated objects as well as performing high-speed cleaning of mildly polluted objects.
Applications and Market of Laser Cleaning
Applications
Laser cleaning finds applications in various industries including rail transportation, aerospace, shipbuilding, automotive, mold market, 3C market, and civil market.
Market
With the continuous advancements in science and technology, tire mold cleaning technology is constantly evolving. Laser cleaning proves to be an efficient and rapid method for removing rust and pollutants while automating the cleaning process through targeted cleaning areas. Not only does laser cleaning offer a cleaner alternative to chemical cleaning processes, but it also minimizes surface damage to the objects being cleaned.
Development Trend of Laser Cleaning
Laser cleaning technology has rapidly emerged as a novel surface cleaning technique over the past decade. Its unique advantages have led to its gradual replacement of traditional cleaning processes in various fields, earning it the reputation of a “green and environmentally friendly” cleaning technology for the 21st century.
Presently, China’s industrial cleaning industry is striving to meet international environmental standards. Laser cleaning, as an eco-friendly and dependable cleaning technology, brings positive news for China’s environmental protection efforts. The continuous development of laser cleaning technology will create numerous new opportunities for laser technology in industrial applications and hold immense potential for further growth.
