VERFAHREN ZUR ENTFERNUNG VON WACHS AUS ZELLSTOFF

摘要

A method for removing wax from a pulp furnish is disclosed. The method is effective for removing wax from a pulp furnish containing waxed old corrugated containers (OCC). In the method, the pulp furnish containing waxed OCC is treated with an agglomeration chemical which separates wax from the fibers and agglomerates the wax for removal by screening. In a preferred embodiment, the pulp furnish is treated with a caustic material to enhance wax removal.
