Filler migration in a suction box
FY 2011-12
Summary
Photocopy paper now contains about 15% calcium carbonate filler, which is often generated on site from exhaust stack CO2. The trend in recent years has been to increase the filler content of paper, with the goal of having approximately 50% filler by weight. This trend results in reduced fibre consumption during papermaking, and has the ancillary benefit of reducing greenhouse gas emissions. One of the important limiting factors in increasing the filler content of paper is that fillers can be dislodged from the paper during passage of the paper web through the suction box. The present research is focussed on understanding the process by which fillers are dislodged from the paper web, with the goal of improving suction box design and operation to allow for higher amounts of filler in paper.
