Handheld laser cleaning machine for rust removal is a technology increasingly used for a variety of applications, including welding pre- and post-treatments, coating removal, and decontamination.
1, laser cleaning 1000w is dry cleaning, no exhaust emissions, will not cause environmental pollution, cleaning residues through the vacuum cleaner recycling.news
2,It can effectively clean another difficult method of cleaning adsorption surface of submicron particles.
3,The laser can be transmitted through fiber optics and matched with robots and robots, easy to achieve long-distance operation, thus used in certain dangerous places to ensure the safety of personnel
4, laser cleaning efficiency, saving time and reducing costs.
5, good controllability and flexibility, easy to implement the selected area, real-time accurate cleaning. If
6, heat-affected zone is small, light stripping cleaning is open to material joining, without thermal damage to surrounding materials without thermal effects. Will not damage the mold – extend the service life of the mold. However
7, automotive tire molds can be achieved online cleaning, fast cleaning speed (≤ 25 minutes / pair), easy to operate, without any consumables (except electricity) and chemicals. So
8, the purchase of laser cleaning system although the previous one-time investment is very high. But the cleaning system can be used steadily for a long time, with low operating costs and less warranty requirements.
1. Ablation Threshold
Laser ablation occurs when layers of material or coatings are removed with a laser beam. This is the process behind all laser cleaning applications. Take laser removal of rusted steel. When the beam hits the surface, the molecular bonds in the dust or rust layer are broken and ejected from the substrate. In less technical terms, you can imagine that the layer to be removed is simply evaporated by the laser beam.
Now, each material has a specific ablation threshold. In order to successfully remove a layer from a given material, the energy delivered by the laser beam must be higher than the ablation threshold for that particular material.
2. Highly selective
Since each material has an ablation threshold, laser cleaning can distinguish between two or more materials when attempting to remove an unwanted layer from an object. Given a large enough difference in ablation threshold between materials, it is possible to select the material to be removed (i.e., the material with the lower ablation threshold) while leaving the other materials unaffected.
3. Powerful Bursts
Fiber laser cleaning systems can remove any given layer using two different methods. The laser beam is either a continuous light wave or pulsed at a given repetitive frequency. Even if the results are nearly identical, the removal speed will vary from method to method.
For a given surface area, putting the same amount of energy into a short pulse will increase the power. This is like using a larger hammer. A pulsed laser beam is more efficient and provides faster removal than a continuous beam.
4. Environmentally friendly
Since this cleaning method uses only the laser beam to evaporate the layer to be removed, there are virtually no consumables. This is the beauty of the laser, which only requires a power plug to be set up and ready to use.
Most importantly, the laser does not use chemical products or solvents. This makes laser surface cleaning one of the safest solutions when removing rust and coatings. Not only is there no chemical waste to dispose of, but employees are completely safe when working near laser cleaners that meet international laser safety standards.
5. Various applications
Currently, the most common handheld laser cleaning machine for rust removal applications include
Welding pretreatment to remove rust and other contaminants from welded areas
Post-weld treatment to remove aluminum and stainless steel oxides
Laser surface treatment to maximize paint adhesion
Laser removal of oxides from specialty alloy ingots
Paint stripping of parts scrapped due to paint defects
Laser cleaning technology, a new field of laser application, can be used in a wide range of materials, such as liquid materials, solid materials and even space. In particular, laser is used to remove solid surface layer, which opens up a new idea of industrial cleaning technology.
