Title

COMPARATIVE INVESTIGATION OF THE EFFECT OF PRE AND POST – REFINING ENZYMATIC TREATMENT ON OCC PULP PROPERTIES

Pages

  254-265

Abstract

 In this research, the effect of different procedures of ENZYMATIC TREATMENT including prerefining and POST-REFINING ENZYMATIC TREATMENT by Endoglucanase on the quality of OCC PULP was investigated. Three pulps including a; control sample (without enzyme addition), b; prerefining ENZYMATIC TREATMENT (enzyme treatment+refining) and c; pre and post refining ENZYMATIC TREATMENT (enzyme+refining+enzyme) were made from OCC PULPs. First optimum ENZYMATIC TREATMENT conditions was determined (concentration of 1u and time duration of 0.5 hour, under constant process conditions) and then this optimum condition was applied and refining accomplished at 2000 revolutions. The results of this research indicated that applying enzymatic pre-treatment imparts efficient improvement in both physical and MECHANICAL PROPERTIES of paper and handsheets showed the highest strength than to the other treatments. Using Endoglucanase at two stages (before and after refining) improved pulp drainability and decreased the paper strength properties. In general, the maximum tear index was observed applying PRE-REFINING ENZYMATIC TREATMENT.
