Abstract

The influence of chemical treatment time and temperature on production of CHEMI-MECHANICAL PULP from COLZA stem is studied. Three treatment times (15, 30 and 45 minutes) and two treatment temperatures (125 and 145 oC) were investigated. Chemical charge as 4% NaOH and 8% Na2SO3 as was kept constant. Accepted pulp YIELD varied between 53.8% and 63% and the total YIELD was measured between 57.6% and 68.9%. The residual lignin in lower YIELD pulp was 19% and higher YIELD pulp was 20.4%. Holocellulose content of pulps varied between 72.5%- 74% and freeness was between 520-590 ml CSF. Fiber classification using Bauer-McNett procedure showed that the average FIBER LENGTH of unrefined pulp is between 0.6-0.7 mm, and the fine content (P100) is between 9% and 10.4%, Pulp freeness was reduced from original value of 520 to 590 ml CSF to about 300 ml CSF as pulps were refined in PFI mill applying 500 revolutions. The unrefined pulp strength including tensile index, burst index and tear index were measured as 15.48- 26.13 N.m/g, lower than 1 kPa.m2/g and 2.91- 4.34 mNm2/g respectively. All the indices after refining in PFI mill using 500 revolution were increased to 19.74-35.19 N.m/g, Max.1.70 kPa.m2/g and 3.21- 4.68 mNm2/g respectively.
