MODIFYING RESIN VISCOELASTICITY BY MULTIFUNCTION CAVITATION PROCESSING IN A MAGNETIC FIELD

The viscoelastic properties of polyamide 11 samples were modified by subjecting these specimens to multifunction cavitation within a magnetic field, using a device equipped with a 0.1 mm water jet nozzle. During these trials, a magnetic field was applied to the entire water jet stream while varying the distance between the nozzle and the specimen. The effects of various processing conditions were assessed by monitoring the removal of ink applied to sample surfaces. The results obtained using this technique with and without a magnetic field were also evaluated.
