Abstract (en)
[origin: WO8705834A1] To clean away especially dirt due to pigments and grease, the mouldings are processed ultrasonically in baths which contain essentially insoluble interceptors for collecting the dissolved dirt. This process can be combined with other washing and rinsing stages which take place without the use of ultrasound.
Abstract (fr)
Pour nettoyer des salissures dues essentiellement aux pigments et à la graisse, les pièces moulées sont traitées de manière ultrasonique dans des bains qui contiennent essentiellement des intercepteurs insolubles permettant de connecter les salissures dissoutes. Ce procédé peut être combiné avec d'autres phases de lavage et de rinçage qui se déroulent sans l'action des ultrasons.
