  1. 1. Quantitative microscopy of coating uniformity

    Detta är en avhandling från Sundsvall : Mid Sweden University

    Författare :Christina Dahlström; Mittuniversitetet.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coating uniformity; coating microstructure uniformity; base sheet effects; argon ion beam milling; scanning electron microscopy; image analysis; binder distributions; autocorrelation analysis; random deposition process; simulation;

    Sammanfattning : Print quality demands for coated papers are steadily growing, and achieving coating uniformity is crucial for high image sharpness, colour fidelity, and print uniformity. Coating uniformity may be divided into two scales: coating thickness uniformity and coating microstructure uniformity, the latter of which includes pigment, pore and binder distributions within the coating layer.

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

    Detta är en avhandling från Sundsvall : Mid Sweden University

    Författare :Helena Fjellström; Mittuniversitetet.; [2008]
    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; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP 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.

  3. 3. Printability and Ink-Coating Interactions in Inkjet Printing

    Detta är en avhandling från Fakulteten för teknik- och naturvetenskap

    Författare :Erik Svanholm; Karlstads universitet.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik; Chemical Engineering; Kemiteknik; coating; inkjet; print quality; printability; pigment; silica; polyvinyl alcohol; colorant; ink absorption;

    Sammanfattning : Inkjet is a digital printing process where the ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most inkjet inks have a low viscosity and a low surface tension, which put high demands on the coating layer’s porosity and absorbency characteristics. LÄS MER

  4. 4. Consolidation and structure of paper coating and fibre systems

    Detta är en avhandling från Stockholm : Kemi

    Författare :Christian Kugge; KTH.; [2003]
    Nyckelord :coating colour; ground calcium carvonate; dlqy; dqboxymethylcellulose;

    Sammanfattning : Paper coatings or coating colours are high solidssuspensions that are applied to paper to improve chieflyprintability and optical properties. A paper coatingsuspension, including pigments, binders and thickeners, is acomplex system which must be understood if the end-useproperties of paper are to be improved. LÄS MER

  5. 5. The influence of particle shape of coating pigments on their packing ability and on the flow properties of coating colours

    Detta är en avhandling från Institutionen för pappers- och massateknologi

    Författare :Sven Lohmander; KTH.; [2000]
    Nyckelord :aspect ratio; capillary viscometry; coating colour; filtration. Particle packing;

    Sammanfattning : The influence of particle shape of coating pigments on theirpacking ability and on the flow properties of coating colourshas been investigated. The particle shapes considered werespherical, flaky and acicular (needle-shaped). LÄS MER
