摘要

Juvenile radiata pine PGW has been produced with equivalent, or better, tensile strength and optical behaviour to thermomechanical pulps of the same wood, and of Scandinavian spruce. The PGW pulp qualities, in their raw, "pit-sample" state meet key current industrial TMP quality requirements for SC and LWC paper and almost satisfy projected, "next-generation" TMP requirements for SC. The PGW was produced at an energy saving of ca. 2000 kWh/odt relative to the radiata pine TMP and ca. 1200 kWh/odt relative to the spruce TMP. These desirable pulp performance behaviours combine with the low latewood characteristics of juvenile radiata pine to offer an economically-interesting opportunity for the manufacture of high-quality communication papers. Eucalyptus nitens and black poplar PGW do not offer the same benefits as the juvenile radiata pine PGW.
