    Keywords : ;

    Abstract : .... READ MORE

  4. 7. On Heat and Paper : From Hot Pressing to Impulse Technology

    Author : Marco Francesco Carlo Lucisano; KTH; []
    Keywords : Paper; Impulse Drying; Heat Transfer; Phase Change; Heat-Pipe Effect; Delamination; Flashing;

    Abstract : Impulse technology is a process in which water is removedfrom a wet paper web by the combined action of mechanicalpressure and intense heat. This results in increased dewateringrates, increased smoothness on the roll side of the sheet, andincreased density. READ MORE

  5. 8. Dynamic compressibility of water-saturated fibre networks and influence of local stress variations in wet pressing

    Author : Hannes Vomhoff; KTH; []
    Keywords : ;

    Abstract : .... READ MORE

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

    Author : Olof Steffner; []
    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

  7. 10. Evaluation of Furnishes for Tissue Manufacturing

    Author : Johan Kullander; Lars Nilsson; Christophe Barbier; Thad Maloney; Karlstads universitet; []
    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
