摘要： The present invention provides methods for deinking printed waster paper—particularly methods that use a deinking composition that includes a hydrophobically-modified inorganic particle (“MIP”) to improve ink collection efficiency under traditional alkaline, reduced alkali, and true neutral deinking conditions. Deinking compositions are provided that include a hydrophobically-MIP substrate, a nonionic surfactant, and a fatty acid, or mixtures thereof. The improved ink collection of the present invention can result in deinked pulp of high quality and/or yields that has excellent brightness and effective residual ink concentrations (“ERIC”) values.
摘要翻译：本发明提供了用于脱墨印刷废纸的方法，特别是使用包含疏水改性无机颗粒（MIP）的脱墨组合物以提高传统碱性，还原碱和真正中性脱墨条件下的墨水收集效率的方法。提供了包含疏水性MIP底物，非离子表面活性剂和脂肪酸或其混合物的脱墨组合物。本发明的改进的油墨收集可以产生具有优异亮度和有效的残留油墨浓度（ERIC）值的高质量和/或收率的脱墨纸浆。
