Project Highlight
The effect of high intensity ultrasound on paper fillers and loadings
Project Directors:
Anna Fricker, Dr Andrew Manning and Professor Robert Thompson
Outline:
This investigation explores the effects of subjecting pulped paper to exposure to high intensity ultrasound. It has been noted that the particle size distribution of fillers and loadings are greatly effected by exposure to ultrasound. A variety of pulped papers have been examined and definite trends in the particle size distribution have been recorded. Further examination of the filtrates obtained from the pulps by scanning electron microscopy has revealed information as to how the particles of fillers break down and agglomerate together.
