   University essay from Fakulteten för teknik- och naturvetenskap

   Author : Charlotta Boström; Anna Rosén; [2006]
   Keywords : shrinkage; free drying; restrained drying; Fibre-to-Board; hand sheet properties; fine material; tensile stiffness; simulation;

   Abstract : Fibre-to-board is a simulation model developed at Stora Enso Research Centre Karlstad. Within this model isotropic hand sheet properties are used as input data for prediction of the final multi ply board properties. READ MORE

3. 2. Influence of hardwood, softwoodand fractionated pulp in a stratifiedthree-layered fine paper : Lövved, barrved och fraktionerad massa ochdess inverkan på ett treskiktat finpapper

   University essay from Grafisk teknik

   Author : Mariell Mattison; [2006]
   Keywords : Multi-ply fine paper; three-layer fine paper; stratified forming; simultaneous forming; XPM; Formator; StratEx; AQ-vane; stratified headbox; early wood; late wood; fractionation; fine fraction; coarse fraction; hydrocyclone;

   Abstract : Four different trials of stratified three-layered fine paper, of sulphate pulp, were performed to investigate if stratified fine fraction or fibres from birch can improve the properties of a paper compared to a reference sheet. All trials had five different scenarios and each scenario was calendered with different linear load. READ MORE
