Machine de nettoyage au laser à fibre
Tous les matériaux ont un seuil d'ablation
L'ablation au laser se produit quand une tissu couche ou un revêtement est éliminé avec un faisceau laser. C'est la méthode à l'arrière de toutes les applications nettoyage laser. Prenez l'élimination de la rouille au laser sur l'acier. Lorsque le faisceau touche la surface, les liaisons moléculaires dans la couche de saleté ou de rouille sont endommagées et éjectées du substrat. En beaucoup moins en termes techniques, vous pouvez penser que la couche à éliminer est définitivement vaporisé à travers le faisceau laser.
1:Laser nettoyage principe
Un facile moyen de rapprocher la signification du seuil d'ablation est de l'évaluer au lancer une balle sur un mur. Si vous ne le lancez pas excessivement assez, il en aucun cas passera du différent côté. Même si vous lancez la balle mille fois, vous continuellement échouerez. Le égal s'applique au dérouillage au laser. Vous pouvez tirer le faisceau laser un millier instances toutefois aussi longue tant que la force est sous| |||le seuil d'ablation du tissu avec lequel vous travaillez, rien ne sera jamais enlevé.
Maintenant, chaque tissu a exclusif maisons et par conséquent unique en son genre liaisons moléculaires. En autres mots, chaque tissu a un unique seuil d'ablation. Pour correctement retirer une couche d'un matériau donné, la force transférée à l'aide du faisceau laser| |||devrait être au-dessus du seuil d'ablation de ce matériel spécifique.
2:It is Possible to Remove a Material in a Highly Selective Way
Let’s proceed with our analogy. Imagine there used to be a second, greater wall at the back of the first one and that a ball was once thrown with simply ample electricity to make it over the first wall, however no longer sufficient to make it over the second. The ball would jump off the 2d wall and fall in between the two walls. Once again, no count number how many instances you throw the ball, you will usually get the identical result. You will make it previous the first wall however by no means the second.
Since there is an ablation threshold for every material, laser cleansing can discriminate between two or greater substances when attempting to get rid of an undesired layer from an object. Given a sufficiently giant ablation threshold distinction between the materials, it is viable to choose a cloth to be eliminated (i.e., the one with the decrease ablation threshold) whilst leaving the different cloth untouched.
For example, the rust ablation threshold is plenty decrease than the threshold for frequent metals like metal and aluminum. The identical goes for paint and oil. This widespread hole between two values approves contaminants and coatings to be totally vaporized barring any danger of unfavourable the base fabric underneath. There’s simply now not adequate power for injury to happen.
3: It is Consumable-Free and Environmentally Friendly
As this cleansing technique solely makes use of a laser beam to vaporize the layer to be removed, there are actually no consumables with it. This is the splendor of lasers, which solely want a electricity plug to be set and geared up to go.
On pinnacle of this, lasers use no chemical merchandise or solvents. This makes laser floor cleansing one of the most secure options when it comes to rust and coating removal. Not solely is there no chemical waste to take care of, however personnel are completely protected when working close to laser cleansing machines, which are designed to meet international laser protection standards. Employees won’t want private defensive tools and won’t have to deal with these pesky chemicals.
That being said, seeing that laser cleansing vaporizes substances into fumes, you ought to have a fume extraction system near the laser to make certain that no paint, oil or dirt particles are launched into the air.
4: Laser Cleaning is of Interest for Various Industrial Applications
Removing the burnt rubber residue from tire molds; giving a new lifestyles to historic pipelines; cleansing pipes in nuclear electricity plants; and even large initiatives such as disposing of paint from a rusty bridge and getting ready welding surfaces are all initiatives that can gain from industrial laser cleaning.
This non-contact cleansing method can be used in limitless industrial applications. The solely restrict is the potential to discriminate between the fabric to be eliminated and the one to be protected.
At the moment, the most frequent laser cleansing purposes include:
·Welding pre-treatments to cast off rust and different contaminants from welding areas
·Welding post-treatments to take away aluminum and stainless-steel oxides
·Laser floor education to maximize paint adhesion
·Laser oxide elimination from area of expertise alloy ingots
·Coating elimination simply after the coating system to substitute phase covering in manufacturing lines
·Depainting components that would in any other case be scrapped due to paint defects
Laser ablation is no longer solely used for cleaning, it’s additionally broadly used for other industrial applications.
In Summary
If you are involved in the laser cleansing process, contact a Laserax expert. We can information you via our workstations, manufacturing line options and OEM laser systems.
Laser cleansing solutions can overcome many of the issues confronted with rust elimination and different industrial cleansing applications. By deciding on a precise cloth to be removed, fiber lasers provide a fast, as properly as a set-and-forget answer for many industries.
