  2. 7. Precalendering and its interaction with other unit processes in the manufacturing of woodfree paper and board

    University dissertation from Institutionen för pappers- och massateknologi

    Author : Olof Steffner; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calendering; soft-nip calendering; wet press; compression; deformation; coating; water box;

    Abstract : ABSTRACTDuring calendering, which is done in order to improve its printing properties, the paper is compressed in one or more roll nips. Paper is a viscoelastic material and this will influence its performance during calendering. READ MORE

  3. 8. Evaluation of Furnishes for Tissue Manufacturing

    University dissertation from Karlstad : Karlstads universitet

    Author : Johan Kullander; Karlstads universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : Water removal on a tissue machine becomes progressively more difficult and expensive in each successive zone. Since a big part of the cost is allocated to the drying section, improved water removal in the wet end may lead to huge savings in the manufacturing process. READ MORE

  4. 9. The influence of fibre characteristics on bulk and strength properties of TMP and CTMP from spruce

    University dissertation from Sundsvall : Mid Sweden University

    Author : Niklas Klinga; Mittuniversitetet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : This thesis is intended to contribute to an increased knowledge about the influence of fibre characteristics on bulk and strength properties of thermomechanical pulp (TMP) and chemithermomechanical pulp (CTMP) from spruce. It deals with laboratory sheet properties and how they are affected by the conditions during pressing and drying, e.g. READ MORE

  5. 10. The Influence of Molecular Adhesion on Paper Strength

    University dissertation from Stockholm : KTH

    Author : Malin Eriksson; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi;

    Abstract : This thesis deals with the influence of molecular adhesion on paper strength. By combining the use of high-resolution techniques and silica/cellulose surfaces, with various fibre–fibre and sheet testing techniques, new information regarding the molecular mechanisms responsible for paper strength has been obtained.
