Strength characteristics of chemi-mechanical pulp from rapeseed straw

Popis výsledku v původním jazyce

The objective of this work was to determine the potential application of rapeseed straw in the chemi-mechanical pulping process. Stalks of rapeseed straw (species Brassica napus L. convar. napus) were used for the pulping process. The chemi-mechanical pulping comprises four main operations, viz. chipping, grinding, leaching, and beating. For chemi-mechanical pulps, the influence of caustic soda charge applied in the leaching process upon the bending stiffness and bending modulus of elasticity in the region of reversible deformation was investigated by using a three-point loading method. The preliminary results revealed that the bending modulus of elasticity increases with increasing caustic soda charge from 0.22 to 1.11 kN mm-2 for both basis weights of the handsheets (approx. 260 g m-2 and 520 g m-2). Similarly, the bending stiffness of handsheets having lower basis weight slightly increases with increasing alkaline charge, whereas, for higher basis weight, the effect of alkaline char
