PS&ChE Advanced Paper Making: Additives

Stevens Point, WI
Thursday, April 11, 2024 to Friday, April 12, 2024

This two-day course provides an overview of common paper making additives used in the industry today.

This two-day course provides an overview of common paper making additives used in the industry today. Clear descriptions of how and why these additives work are presented in classroom discussions. Attendees will participate in discussions focused on where additives are introduced into the paper making process, potential interactions with both equipment and other additives, and the relationship between additives and enhanced performance of paper. This course features hands-on exercises on the UW-Stevens Point pilot paper machine where attendees will produce paper with different additives. The group will also evaluate the properties of this paper using typical laboratory tests. Class size is limited to 16 for this course to provide ample opportunities for questions and discussion during classroom sessions and hands-on experiences on the paper machine. Learning outcomes for this course include:

  • Safely participate in the operation of a pilot-scale paper machine
  • Recognize the difference betweeen acid and alkaline papermaking
  • Explain the difference between process additives and product improving additives
  • Produce and evaluate paper with retention aid
  • Produce and evaluate paper with filler
  • Produce and evaluate paper with dyes
  • Describe the difference between wet and dry strength additives
  • Explain the purpose and use of foam control, pitch control and biocides

Dr. Gary Ring

Dr. Gerry Ring is professor emeritus of paper science and engineering at the University of Wisconsin-Stevens Point. In 1980, Ring began his professional career as a Research Scientist for Kimberly-Clark Corporation after obtaining his Ph.D. at the Institute of Paper Chemistry in Appleton Wisconsin. In 1986, Ring joined the faculty of UW-Stevens Point and chaired its paper science (now paper science and engineering) program from 2003 until 2013. 

Dr. Ring has written 15 publications, including editing the Colloid Chemistry of Papermaking Materials textbook. He holds four patents and was recognized in the 1994, 2000 and 2004 editions of Who’s Who Among America’s Teachers.
