   Abstract : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. READ MORE

4. 2. Heterogeneous Film-Forming Latexes : Preparation - Morphology - Mechanical Properties

   Author : Ola Karlsson; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; core-shell; particle morphology; heterogeneous latexes; particle size; crosslinking; hydrophilicity; poly isoprene-co-styrene-co-methacrylic acid ; monomer partitioning; internal particle viscosity; transmission electron microscopy TEM ; calorimetric reactor; two-stage; seeded emulsion polymerization; film morphology; mechanical properties; paper coating.; Polymer technology; biopolymers; Polymerteknik;

   Abstract : This thesis describes the preparation of heterogeneous latexes, which may serve as binders in coating applications, and the characterization of these. The latexes were prepared in two-stage seeded emulsion polymerization. READ MORE

5. 3. Process intensification in mechanical pulping : Reduced process complexity and improved energy efficiency

   Author : Christer Sandberg; Per Engstrand; Jan-Erik Berg; Göran Bengtsson; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This work shows that, for newsprint quality grades, the production processes for mechanical pulp can be simplified, and the specific electrical energy demand can be reduced with around 600 kWh/ton (30%). The purpose of the work is to demonstrate how the production cost for mechanical pulps can be decreased through increased energy efficiency and reduced number of unit operations. READ MORE

6. 4. Beyond averages – some aspects of how to describe a heterogeneous material, mechanical pulp, on particle level

   Author : Olof Ferritsius; Birgitta A. Engberg; Per Engstrand; Mats Rundlöf; Øyvind Weiby Gregersen; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Visualisation; Uniformity; Distributions; Independent common factors; Weighted fibre length; Fibre bonding; Fibrillation; Curl; Wall thickness; Particle analyser characterisation; Raw material; CTMP; Process configuration; Sampling accuracy;

   Abstract : For a more profound understanding of how a process works, it is essential to have a relevant description of the material being processed. With this description, it will be easier to evaluate and control processes to produce more uniform products with the right properties. READ MORE

7. 5. High strength paper from high yield pulps by means of hot-pressing

   Author : Tove Joelsson; Per Engstrand; Gunilla Pettersson; Anna Svedberg; Samuel Schabel; Mittuniversitetet; []
   Keywords : high yield pulp; hot-pressing; lignin; paper properties; wet strength;

   Abstract : AbstractHigh Yield Pulp (HYP), i.e. TMP, SGW or CTMP, is normally used in printing papers (News, SC and LWC) or in a middle layer on cardboard i.e. READ MORE
