Abstract

L'invention concerne un procédé de régénération de tôles vernies et/ou enduites d'une couche de fond, en particulier pour la régénération de carrosseries brutes de véhicules, notamment de voitures particulières, et a pour but d'effectuer de manière simple une régénération de carrosseries ou de tôles présentant des défauts dans la couche de fond ou dans le vernis. A cet effet, l'invention est caractérisée en ce que la tôle enduite d'un vernis ou d'une couche de fond, ou la carrosserie ainsi enduite, est débarrassée totalement du revêtement par traitement au jet d'eau, ou bien uniquement la couche extérieure du revêtement, ou plusieurs couches extérieures, sont complètement enlevées par traitement au jet d'eau, et en ce que le traitement au jet d'eau s'effectue sous haute pression, d'au moins 1000 bar, de préférence entre 1500 bar jusqu'à plus de 2800 bar.

Claims (5)
