New Associate Professor Jan‑Erik Berg
Seminar in chemical engineering for academic title Associate Professor with Jan-Erik Berg. Title of the seminar “Refining gentleness – a key to bulky CTMP”.
Chemithermomechanical pulp (CTMP) is often used in middle layers of multiply paperboards due to its high bulk at specified strength. Such a CTMP should consist of well-separated undamaged fibres with sufficient bonding capacity. A new parameter, Refining gentleness that accounts for temperature, bound sulphonate content, refining gap, and refiner diameter, is believed to be a versatile tool in research and process development in order to achieve bulky CTMP.
