METHOD OF SEPARATION OF LACQUER COATINGS FROM PLASTIC SURFACES Russian patent published in 2004 - IPC

FIELD: technologies of cleaning surfaces of plastic items from lacquer coatings.

SUBSTANCE: the invention is dealt with the field of technologies of cleaning surfaces of plastic items from lacquer coatings. The method includes usage of a cleaning solution and additional action on it. At that the plastic items with a lacquer coating is exposed to comminution up to particles sizes of no more than 5 mm and prepare a water suspension with a share of the solid phase of 20-70 %. The suspension is subjected to an additional grinding expos a padding grist up to the particle sizes of no more than 1 mm and to vibration-cavitational action in an installation with a rotated rotor and an immovable stator supplied with perforation. The suspension is then passing through the installation with intensity of flow of 20 g/cm² per a second at the rate of the rotor rotation of no less than 15 m/s. The method is environmentally appropriate and ensures the high degree of clearing of a plastic surface.

EFFECT: the method is environmentally appropriate and ensures the high degree of clearing of a plastic surface.
