1. AKD sizing : dispersion colloidal stability, spreading and sizing with pre-flocculated dispersion
Abstract : Alkylketene dimer, AKD, dispersions are used in the paper industry to obtain paper grades with a hydrophobic character i.e. resistance to sorption of water. AKD is used in neutral to alkaline internal sizing, pH in the interval of 6-9. READ MORE

3. Emulsification of Alkyl Ketene Dimer (AKD) -characterization of dispersions and emulsifiers
Abstract : Alkyl Ketene Dimer (AKD) is a commonly used hydrophobizing agent in the paper industry, introducing capillary absorption barriers for polar liquids, which makes the paper more resistant to liquid penetration. Since AKD is a so-called internal sizing agent it is usually added in the form of a water-borne dispersion. READ MORE

4. A toolbox for improving the processability of composites with a high content of thermomechanical pulp
Abstract : The use of oil-based products causes large volumes of non-biodegradable waste and contributes to climate changes. Focus has consequently shifted towards the use of polymers derived from wood. The processability of such polymers, however, presents a challenge but this can be overcome through the use of composite materials, i.e. READ MORE

5. Wetting and Capillary Flow of Surfactant Solutions and Inks
Abstract : This thesis presents results of a series of experimental studies on the spreading dynamics of small drops of complex solutions on solid surfaces. The capillary flow dynamics of complex solutions have also been investigated. READ MORE
