Importance of Zeta Potential to the Paper Manufacturing Process

Example 1 – A Fine Paper Mill. At a fine paper mill, typical ash retention reduced from 35% to 25%. All the usual parameters were investigated, basis weight, speed, pH, additives and procedures, but non correlated with this problem. However, the head box zeta potential was rather high at about +9 mV and increased occasionally to +17 mV.

Pulp Additives

Calcium carbonate can be added to pulp as an alkaline to lower the pH, and will make the resulting paper more opaque as it fills the spaces between the fibers. This can be desirable for digital or other printing processes. (See "For Beginners" in Hand Papermaking Newsletter #82 for more on making paper for digital printing.)
