Typically, these agents are chemically modified mineral oils, where hydrophilic groups have been added to the molecular structures to make them partly soluble. There are three specific types of surfactants, are important in deinking application: 1-Detergents: to remove the ink from fiber. 2-Dispersents: to keep the ink particles dispersed and prevent re-deposition onto the fibers. 3-Foaming agents: to reduce the surface tension of water and to promote foam formation. Other chemicals, such as caustic soda, sod. Silicate and borax are also used to enhance the action of the surfactants.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
