Mitigating pitch-related deposits at a thermomechanical pulp-based specialty paper mill

摘要

A mill in Eastern Canada experienced significant sticky deposit formation on one of the guide rolls of the supercalendering stack in its supercalendered paper production line. To investigate and minimize the formation of those sticky deposits, the researchers collected deposit samples from a supercalender stack and analyzed them for their chemical compositions, metal ion contents, and thermal properties.
