Macchina per la pulizia del laser a fibra

Tutti i materiali hanno una soglia di ablazione

L'ablazione laser si verifica quando uno strato di tessuto o ​​un rivestimento viene eliminato con un raggio laser. Questo è il metodo sul retro di tutte le applicazioni di pulizia laser. Prendi rimozione laser della ruggine sull'acciaio. Quando il raggio colpisce la superficie, i legami molecolari nello sporco o ​​strato di ruggine vengono danneggiati ed espulsi dal substrato. In molto meno termini tecnici, puoi pensare che lo strato da eliminare è definitivamente  vaporizzato attraverso il raggio laser.
1:Laser pulizia principio
Un modo facile per avvicinarsi il significato della soglia di ablazione è di valutare il lancio una palla sopra un muro. Se non lo lanci troppo a sufficienza, in nessun modo farà il altro lato. Anche se lanci la palla mille volte, fallirai continuamente fallirai. L' uguale si applica alla rimozione della ruggine dal laser. Puoi sparare il raggio laser mille istanza comunque quanto lungo quanto la forza è sotto| |||la soglia di ablazione del tessuto con cui stai lavorando, nulla verrà mai rimosso.
Ora, ogni tessuto ha case esclusive e quindi unico nel suo genere  legami molecolari. In altre parole, ogni tessuto ha una unica soglia di ablazione. Per correttamente rimuovere uno strato da un dato materiale, la forza trasferita con l'ausilio del raggio laser| |||dovrebbe essere al di sopra della soglia di ablazione di quel materiale specifico.

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.
