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

    Författare :Helena Fjellström; Hans Höglund; Magnus Paulsson; Arthur Ragauskas; Mittuniversitetet; []
    Nyckelord :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;

    Sammanfattning : 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.
