1. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials
University essay from KTH/MaterialvetenskapAbstract : Fibers are interesting materials alternative to replace conventional fossil-based plastics, as they are bio-based and do not lead to CO2 emissions. Due to their limited ductility, it is difficult to use them to make complex three-dimensional shapes. READ MORE

2. Development of a Profile Sample Cutter
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : The pulp- and paper industry is a key industry globally and stands for a production of 600 million tonnes pulp and paper worldwide with a total revenue of 400 billion dollars. Due to high quality requirements on paper, it is important to use instruments that control that the produced paper fulfill the promised requirements. READ MORE

3. Predictions of Pulp and Paper Properties Based on Fiber Morphology
University essay from KTH/Skolan för kemivetenskap (CHE)Abstract : The aim is to investigate models that predicts the potential of pulp and evaluate the relevance of the zero-span tensile index within these. Two chemical pulps made from softwood and eucalyptus were refined in a Voith-beater with different energy input in order to study the change of fiber morphology signals and other pulp and paper properties.

4. The influence of pH on fiber and paper properties : Different pH levels during beating and sheet forming
University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaperAbstract : The effect of pH on fiber and paper properties, during beating and sheet formation, was investigated for three different pulps. The pulps were pH adjusted to four different pH levels between 3 and 9. Isotropic laboratory sheet were made of both unbeaten and beaten pulps. READ MORE

5. Correlations between fibre properties and paper properties
University essay from KTH/Skolan för kemivetenskap (CHE)Abstract : The understanding of what properties the fibre should have in order to give the right end-product paper properties, along with the type of processing, is a subject for a lot of research and development. Today the ability to measure fibre properties on-line is widely used for pulps. READ MORE
