Les salet\u00e9s qui se sont infiltr\u00e9es dans le liquide de nettoyage sont d\u00e9tach\u00e9es et \u00e9vacu\u00e9es par l'effet de cavitation des ultrasons. Cela permet de r\u00e9duire le temps de nettoyage.<br>En principe, d'autres forces (buses, courants et oscillation des pi\u00e8ces) peuvent \u00e9galement am\u00e9liorer l'efficacit\u00e9 de nettoyage des bains aqueux. Ces m\u00e9thodes peuvent \u00eatre plus efficaces que les ultrasons pour le nettoyage de grandes pi\u00e8ces. Pour les pi\u00e8ces fines ou d\u00e9licates, les ultrasons ne peuvent pas \u00eatre remplac\u00e9s par d'autres forces.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>CHEMIE<\/strong><\/h2>\n\n\n\n<p><br>Le liquide de nettoyage a pour fonction de mouiller compl\u00e8tement l'objet \u00e0 nettoyer et d'\u00e9tablir un contact liquide avec la surface. Les salissures doivent \u00eatre dissoutes ou infiltr\u00e9es par le choix correct de la composition chimique du liquide de nettoyage.

Les liquides de nettoyage chauff\u00e9s augmentent l'efficacit\u00e9 du nettoyage. L'utilisation d'ultrasons dans des liquides de nettoyage aqueux \u00e0 des temp\u00e9ratures de 50 \u00e0 60 \u00b0C produit un effet de nettoyage optimal.
