| Résumé : |
Fears have been expressed about the difficulty of deinking waste paper generated by the Indigo printing process. In this study, high-intensity ultrasound has been used to remove ink from Indigo digitally printed papers and break the ink particles down to sizes which are compatible with the flotation process used in deinking plants. The influences of temperature and power density have been studied and both found to have a significant effect on the resultant ink particle-size distributions. Almost 100% ink detachment has been achieved using a combination of ultrasound and aqueous washing. The conclusion is that detachment and particle-size reduction using ultrasound and aqueous washing suggests that Indigo digitally printed papers may not be so difficult to deink and recycle as originally thought. |
