| titleOfInvention | Deinking of waste printed paper |
| abstract | PURPOSE: To efficiently separate a finely divided ink component from a pulp slurry obtained by the maceration of waste printed paper and to obtain regenerated pulp without lowering pulp yield, etc., by adding an organic solvent capable of floating and separating an ink component to a pulp slurry prior to the separation treatment. n CONSTITUTION: An ink component is separated from a pulp slurry produced by macerating waste printed paper. In the above process, an organic solvent capable of floating and separating the ink component is added preferably in the form of O/W-type emulsion to the pulp suspension prior to the separation treatment. The organic solvent is preferably the one having a specific gravity of <1.0 and selected from n-hexane, n-decane, ligroin, kerosine, di-n-butyl ether, diisoamyl ether, diethyl acetal and ethyl methyl acetal. n COPYRIGHT: (C)1991,JPO&Japio |
