Metal rusting is a chemical reaction that cannot be avoided at present, and rusting is essentially an oxidation reaction of metal. The most common rusting phenomenon is that iron products have been exposed to the air for a long time and have an oxidation reaction with oxygen, or are eroded by oxygen elements in water to become oxides. After rusting, the rust on the metal surface needs to be cleaned while reusing.
As a new generation of high-tech products for industrial surface cleaning, laser rust removal machine has played an important role in rust removal.
Laser cleaning has advantages that traditional cleaning does not have, and laser cleaning is gradually replacing traditional cleaning.
The principle of laser cleaning is to use high-frequency high-energy laser pulses to irradiate the surface of the workpiece, and the coating layer can instantly absorb the focused laser energy, so that the oil stains, rust spots or coatings on the surface are instantly evaporated or peeled off, and the surface attachments or surfaces can be removed efficiently at high speed. The coating is cleaned in a way that the laser pulses with very short action time will not harm the metal substrate under the proper parameters.
Comparison of advantages of laser cleaning
1. Environmental advantages
Laser cleaning is a "green" cleaning method without the use of any chemicals and cleaning fluids. The cleaned wastes are basically solid powders, small in size, easy to store, recyclable, free of photochemical reactions, and no pollution.
Laser cleaning can reduce environmental pollution problems caused by chemical cleaning. Often an exhaust fan can solve the problem of waste generated by cleaning.
2. Effect advantage
The traditional cleaning method is often contact cleaning, which has a mechanical force on the surface of the cleaned object, damages the surface of the object or the cleaning medium is attached to the surface of the object to be cleaned, and cannot be removed, resulting in secondary pollution. Contact, no thermal effects, will not damage the substrate, so these problems are solved.
3. Control advantage
The laser can be transmitted through the optical fiber, cooperate with the robot hand and the robot, and realize the long-distance operation conveniently.
4. Convenience advantage
Laser cleaning can remove various types of contaminants on the surface of various materials, achieving a cleanliness that cannot be achieved by conventional cleaning. Furthermore, contaminants on the surface of the material can be selectively cleaned without damaging the surface of the material.
5. Cost advantage
Laser cleaning is fast, efficient, and saves time; although the initial investment of a laser cleaning system is high, the cleaning system can be used stably for a long time, with low operating costs, and more importantly, it can be easily automated.
