Title

Einfluß von Holzaufschlußverfahren (TMP-, CTMP-Verfahren) und Aufschlußbedingungen auf die physikalisch-technologischen Eigenschaften von mitteldichten Faserplatten (MDF)

Other Title
Influence of pulping (TMP, CTMP) process and conditions on the physical and technological properties of medium-density fibreboards (MDF)
Abstract
Thermo-mechanical pulps (TMP) and chemo-thermomechanical pulps (CTMP) were made from spruce under different pulping conditions. The fibres were dried at 70 degrees C. Medium density fibreboard (MDF) were made in pilot plant scale from the pulps using urea-formaldehyde resin as a binder. The results of testing the physical properties reveal, that the pulping temperature has a significant influence on the thickness swelling and water absorption of the boards. MDF from fibres produced at high pulping temperature (180 degrees C) generally show lower thickness swelling and water absorption than MDF made from fibres produced at lower pulping temperature (140 degrees C and 160 degress C).
