Title

The product off pulp from hornbeam with alkaline sulfite-AQ process

Pages

  479-494

Abstract

 The objective of this study was to investigate the modification of neutral sulfite semi chemical (NSSC) pulping liquor by applying changes in the percentage of chemicals, increasing alkalinity and changing the pulping duration for the production alkali sulfite (AS). Among the pulps, the best combination was acceptable with respect to the residual alkalinity (pH> 11) and the acceptable kappa number (about 17) and the lowest amounts of so-called undercooked wood (or “ rejects” ) was selected. Pure AS pulp and also the mixing of different percentages of AS pulp with NSSC pulp were compared. The results showed that the overall strength of the modified pulp compared with the initial NSSC pulp increased. So that the alkali sulfite (AS) and NSSC is about 66. 2 and 32. 4 N. m/ g, respectively. By adding more amounts of this pulp in furnish, by increasing the required strength of the paper, the consumption of pulp from the imported long fiber could be reduced while maintaining the paper's strength properties.
