- Effet photothermique (le plus couramment utilis\u00e9) : Les polluants absorbent l'\u00e9nergie du laser et s'\u00e9chauffent instantan\u00e9ment, se vaporisant ou se dilatant thermiquement. Lorsque la force d'expansion est sup\u00e9rieure \u00e0 la force d'adh\u00e9sion, les polluants sont \u00e9limin\u00e9s. Le substrat est peu affect\u00e9 en raison de sa haute r\u00e9flectivit\u00e9 et de la dissipation rapide de la chaleur. Convient pour la rouille, les taches d'huile et les rev\u00eatements.
- Effet photochimique (principalement laser ultraviolet) : L'\u00e9nergie des photons brise les liaisons mol\u00e9culaires des polluants, les d\u00e9composant en petites mol\u00e9cules facilement volatiles. Convient aux salissures organiques et aux rev\u00eatements polym\u00e8res, souvent utilis\u00e9s pour les reliques culturelles et les pi\u00e8ces de pr\u00e9cision.
- Effet d'onde de choc photom\u00e9canique\/plasma : Les lasers \u00e0 impulsion courte (nanoseconde\/picoseconde\/femtoseconde) g\u00e9n\u00e8rent de fortes ondes de choc ou des forces d'expansion du plasma, ce qui permet d'\u00e9liminer physiquement les polluants de la surface des substrats fragiles\/sensibles \u00e0 la chaleur sans endommager le mat\u00e9riau de base.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

1. \u00c9mission laser : Un laser puls\u00e9 (tel qu'un laser \u00e0 fibre ou un laser Nd:YAG) \u00e9met un faisceau laser d'une longueur d'onde (g\u00e9n\u00e9ralement 1064 nm), d'une largeur d'impulsion et d'une densit\u00e9 d'\u00e9nergie sp\u00e9cifiques.
2. Focalisation du faisceau : Un syst\u00e8me optique concentre le faisceau laser en un petit point (0,1-5 mm), ce qui permet d'obtenir une densit\u00e9 d'\u00e9nergie suffisante pour le nettoyage.
3. \u00c9limination des contaminants : Selon les m\u00e9canismes d\u00e9crits ci-dessus, les contaminants sont vaporis\u00e9s, d\u00e9compos\u00e9s ou \u00e9limin\u00e9s par les ondes de choc sans endommager le substrat.
4. Collecte des d\u00e9chets : Un syst\u00e8me de ventilation permet d'\u00e9liminer les poussi\u00e8res et les vapeurs afin d'\u00e9viter toute pollution secondaire.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Absorption s\u00e9lective : Ciblage de longueurs d'onde sp\u00e9cifiques pour maximiser l'absorption par les contaminants tout en garantissant une r\u00e9flectivit\u00e9 \u00e9lev\u00e9e des substrats.<\/p>

- Seuil de densit\u00e9 \u00e9nerg\u00e9tique : D\u00e9passer les seuils d'\u00e9limination des contaminants tout en restant en de\u00e7\u00e0 des seuils d'endommagement du substrat, contr\u00f4l\u00e9 avec pr\u00e9cision par la largeur d'impulsion, la puissance et le diam\u00e8tre du spot.<\/p>

- Caract\u00e9ristiques des impulsions : Les impulsions courtes (nanosecondes et moins) minimisent l'accumulation de chaleur, prot\u00e9geant ainsi les substrats.<\/p>

- Configuration du syst\u00e8me : Le syst\u00e8me comprend g\u00e9n\u00e9ralement quatre modules principaux : le g\u00e9n\u00e9rateur laser, le syst\u00e8me de focalisation optique, la plate-forme de contr\u00f4le des mouvements et le syst\u00e8me de surveillance intelligent. Le g\u00e9n\u00e9rateur laser produit des impulsions laser \u00e0 haute puissance de cr\u00eate ; le syst\u00e8me optique focalise et balaie le faisceau ; la plate-forme de contr\u00f4le des mouvements assure un positionnement relatif pr\u00e9cis et contr\u00f4lable entre la t\u00eate laser et la pi\u00e8ce \u00e0 usiner ; le syst\u00e8me de surveillance intelligent contr\u00f4le le processus de nettoyage en temps r\u00e9el pour garantir la qualit\u00e9 du nettoyage.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

- Les poussi\u00e8res et les fum\u00e9es g\u00e9n\u00e9r\u00e9es pendant le nettoyage sont collect\u00e9es et trait\u00e9es par un syst\u00e8me d'\u00e9chappement, ce qui minimise la pollution de l'environnement.<\/p>

3. Haute pr\u00e9cision et forte contr\u00f4labilit\u00e9<\/p>

- La profondeur et la port\u00e9e du nettoyage peuvent \u00eatre contr\u00f4l\u00e9es avec pr\u00e9cision en ajustant la puissance du laser, la largeur d'impulsion, le taux de r\u00e9p\u00e9tition, la taille du point et la vitesse de balayage.<\/p>

- Il permet un nettoyage localis\u00e9 sans endommager les zones environnantes, ce qui le rend adapt\u00e9 aux pi\u00e8ces de pr\u00e9cision et \u00e0 la restauration d'artefacts.<\/p>

4. Zone affect\u00e9e par la chaleur minimale<\/p>

- Utilise des lasers \u00e0 impulsions courtes (nanoseconde, picoseconde, femtoseconde) qui concentrent la lib\u00e9ration d'\u00e9nergie dans un laps de temps extr\u00eamement court, minimisant ainsi la diffusion de la chaleur.<\/p>

- Il produit une petite zone affect\u00e9e thermiquement sur les substrats, ce qui le rend adapt\u00e9 aux mat\u00e9riaux sensibles \u00e0 la chaleur et aux composants de pr\u00e9cision.<\/p>

5. Efficacit\u00e9 de nettoyage \u00e9lev\u00e9e<\/p>

- Le balayage laser rapide permet de nettoyer en continu de grandes surfaces.<\/p>

- S'int\u00e8gre facilement aux robots et aux lignes de production automatis\u00e9es pour am\u00e9liorer l'efficacit\u00e9 de la fabrication.<\/p>

6. Large applicabilit\u00e9<\/p>

- Capable de nettoyer divers substrats, notamment les m\u00e9taux, le verre, la c\u00e9ramique, la pierre et les plastiques.<\/p>

- \u00c9limine divers contaminants tels que la rouille, le tartre, les taches d'huile, les rev\u00eatements, les couches de peinture, les r\u00e9sines, les d\u00e9p\u00f4ts de carbone et les impuret\u00e9s particulaires.<\/p>

7. Fonctionnement simple et entretien facile<\/p>

- Il est dot\u00e9 d'un syst\u00e8me de commande num\u00e9rique avec une interface intuitive, qui permet de d\u00e9marrer et de r\u00e9gler les param\u00e8tres \u00e0 l'aide d'un seul bouton.<\/p>

- Il s'agit d'un laser \u00e0 longue dur\u00e9e de vie et \u00e0 faibles co\u00fbts de maintenance ; l'entretien principal consiste \u00e0 nettoyer les composants optiques et \u00e0 inspecter le syst\u00e8me de refroidissement.<\/p>

8. Capacit\u00e9 de nettoyage s\u00e9lectif<\/p>

- Exploite les diff\u00e9rences d'absorption laser sp\u00e9cifiques aux mat\u00e9riaux pour \u00e9liminer les contaminants sans endommager le substrat.<\/p>

- Id\u00e9al pour les applications exigeant une qualit\u00e9 de surface \u00e9lev\u00e9e, telles que les composants a\u00e9rospatiaux, les dispositifs \u00e0 semi-conducteurs et les objets culturels.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
