  1. 1. The influence of stress variations in wet pressing

    University dissertation from Stockholm : Fiber- och polymerteknologi

    Author : Jörgen Gullbrand; KTH.; [2004]
    Keywords : press felts; roughness; smoothness; surface structure; uniformity;

    Abstract : Two methods for the measurement of micro-scale stressvariations of press felt surfaces were developed. The methodswere based on a thin plastic film that was coated with anopaque stress-sensitive layer (Cronapress conversion film). Thefilm was compressed between a felt and a smooth surface. READ MORE

  2. 2. On the Modelling of Mechanical Dewatering in Papermaking

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Vinicius Lobosco; KTH.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; paper; modelling; dewatering; forming; wet pressing; fibre network stress; rheology; hysteresis; intra-fibre water; compressibility; structural stress; stress-strain; restricted gels; swelling;

    Abstract : Most of the water fed into a paper machine is removedmechanically in the forming and press sections. One of thefactor which has an important influence on mechanicaldewatering, i.e. in both forming and pressing, is thestress-strain behaviour of the fibre network. READ MORE

  5. 5. On Heat and Paper From Hot Pressing to Impulse Technology

    University dissertation from Stockholm : Fiber- och polymerteknologi

    Author : Marco Francesco Carlo Lucisano; KTH.; [2002]
    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
