摘要
Deinking of impact and nonimpact printed paper is accomplished by repulping the printed paper in an alkali aqueous medium containing a deinking composition comprising one or more nonionic surfactants and/or alkanols. The presence of the deinking composition causes ink particles to agglomerate, which are removed from the aqueous medium by size and density separation. The invention provides an agglomeration method with high ink removal from all types of impact and nonimpact printed paper.
