Electric treatment for hydrophilic ink deinking [PDF]
Water Science and Technology, 2017 Hydrophilic inks have been widely used due to higher printing speed, competitive cost and being healthy non-organic solvents. However, they cause problems in both product quality and process runnability due to their hydrophilic surface wettability, strong negative surface charge and sub-micron size.
