摘要

Neutral Deinking has become a reality in the newsprint recycle industry for mills using 75% or higher old newspaper content. A unique chemical system that successfully detaches and removes ink from fiber under neutral pH (6.5-7.5) has been jointly development between Eka Chemicals, Paprican and Bowater, Thunder Bay. The technology has been applied on an industry scale at several operations and evaluated globally. The objective of this paper is to review the benefits of the neutral deinking technology, compare the performance of batch vs drum pulpers under neutral conditions and outline the results at the several mill scale evaluations. The review of sulphite based neutral deinking will examine the effects of removing caustic and peroxide from the pulper chemistry on pH, ink fragmentation, ink detachment, residual ink after flotation, and brightness using data collected during implementation of the technology in bench and mill scale trials in North American, the Asia-Pacific region and Europe.
