The Usefulness of Two-Side ERIC Buchner Handsheets for Deinking Agent Development

Session 13  •  November 3  •  1:30pm - 3:00pm

In the recent view of the TAPPI Official Test Method T 567, “Determination of effective residual ink concentration (ERIC) by infrared reflectance measurement," it was noted that the method requires a uniform ink distribution, formation, and grammage in all three dimensions thus making the TAPPI T 218, “Forming Handsheets for Reflectance Testing of Pulp (Büchner Funnel Procedure),” not effective for ERIC analysis. Yet, TAPPI T 218 was the common procedure for preparation of handsheets at mill and lab scale.

This presentation will discuss how the two-sidedness or non-uniform ink distribution of ink can be useful in evaluating and selecting deinking agents for newsprint deinking. Attendees will gain insight into what has been seen in mill settings and in development of deinking agents at lab scale.
