  2. 1. Optics of coated paperboard : Aspects of surface treatment on porous structures

    Author : Erik Bohlin; Caisa Johansson; Magnus Lestelius; Per Edström; Per-Åke Johansson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : Calendering of coated and uncoated paper is widely used to enhance optical properties such as gloss and print quality. The aim of this thesis is to characterize coatings and prints, and to validate models using experimental results from optical measurements of physical samples. Calendering of coated paper often leads to a brightness decrease. READ MORE

  4. 2. Inhibition of light-induced colour reversion of wood-containing papers by means of coating

    Author : Helena Fjellström; Hans Höglund; Magnus Paulsson; Arthur Ragauskas; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-yield pulp; CTMP; birch; light-induced; ageing; photo-stabilising; lignin; coating; pigment; kaolin; calcium carbonate; titanium dioxide; binder; FWA; Chemical engineering; Kemiteknik;

    Abstract : The main purpose of this thesis was to find ways to maintain a low level of light‐induceddiscolouration at an increased addition of mechanical and chemimechanical pulps in coated highqualityfine paper and magazine paper grades. Current technology allows the production of highyieldpulps such as thermomechanical and chemimechanical pulps with properties suitable formanufacturing high‐quality paper or paperboard with a low basis weight.
