Production of NSSC Cellulosic Pulp Fibers from Eucalyptus Cameldulensis- Juniper Publishers
JUNIPER PUBLISHERS- ACADEMIC JOURNAL OF POLYMER SCIENCE Abstract This study has aimed to investigate production of neutral sulfite semi-chemical (NSSC) pulping from eucalyptus camaldulensis in Zabol, Sistan & Balouchestan, Iran. Chemical composition including cellulose, lignin, extractive and ash were measured (48.33%), (28.49%), (5.94%) & (0.65%) respectively, while dimension of fibers including length (0.935mm), diameter (19.13μm), lumen cavity (8.89μm) & cell wall thickness (5.12μm). Cooking conditions were consist of three levels of chemical charge (10, 14 & 18% on O.D weight), constant time of 90min, constant temperature of 170 °C & liquor to wood ratio of 7:1. The pulps were refined to 400±25mL, CSF & 127gm-2 hand sheets were made. Finally, strength properties of the pulps we...
