Laser cleaning technology uses a laser beam to heat the surface of a work-piece. This causes dirt and rust to be vaporized or peel off, and cleans the surface. Although the mechanism of laser cleaning is not well understood, the thermal and vibration effects of laser can be recognized. The laser beam emits a radiation that is absorbed by the pollutant on the surface being treated. Large energy is absorbed rapidly, forming a plasma (highly unstable gas). This creates a shock wave. The shock wave causes pollutants to split and be removed.
Traditional industrial cleaning has flaws
1. Mechanical friction cleaning: High cleanliness but easy to cause damage to the substrate
2. Chemical corrosion cleaning: no stress effect, but serious pollution;
3. Liquid solid jet cleaning: High flexibility, low stress, and cost-effective waste liquid treatment.
4. High frequency ultrasonic cleaning is a good option, but it has a limited cleaning area. The cleaned workpiece must be dried.
Laser Cleaning: Comparison of the Advantages
1.The Advantages of Environmental Protection
Laser cleaning is an environmentally friendly cleaning method that does not require the use of chemicals or cleaning solutions. The waste is small in volume, easily stored, recyclable, and there is no photo-chemical reaction. This can solve the environmental pollution problem caused by chemical cleaning. An exhaust fan is often able to solve the problem of cleaning-generated waste.
2. Effect Advantage
Contact cleaning is the most common method of cleaning. This uses mechanical force to damage the object's surface. Or the cleaning agent sticks to it, which can cause secondary pollution. These problems can be easily solved by Laser cleaning machine, which does not cause any damage to the substrate.
3. Control Advantages
Laser can be transmitted via optical fiber and cooperates with robot and manipulator, enabling remote operation to be realized conveniently. It can also clean parts that are difficult to reach using traditional methods. This can be used in dangerous areas to ensure safety for personnel.
4 Convenient Advantages
Laser cleaning is able to remove all types of pollutants from the surfaces of different materials and can achieve a level of cleanliness that traditional cleaning cannot. Laser cleaning can be used to selectively remove pollutants from the surface without damaging the material.
5. Cost Advantage
Laser cleaning is efficient, fast, and time-saving. Although it is expensive to purchase a laser cleaning system early, the system can be used for a long period of time without any maintenance costs. It can also operate automatically, which is incredibly convenient. Cost calculation: A single unit cleans 8 square meters. The operation cost is approximately 5 kw/hour. This means that the cleaning cost for a single unit is only 40 cents per sq. m.
Laser cleaning machine is a revolutionary cleaning technology that offers many benefits, including high efficiency, environmental protection, and high efficacy. This is one of the most important development areas of laser technology today and offers many potential applications. It is well-suited for use in shipbuilding, aerospace, railroad transit, automobile manufacturing and steel manufacturing, electronic industry as well as medical treatment and cultural heritage restoration.
