  1. 1. Surface and porous structure of pigment coatings Interactions with flexographic ink and effects on print quality

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Erik Bohlin; Karlstads universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coating; Pigment; Calendering; Porosity; Flexographic Printing; Print quality; Chemical Engineering; Kemiteknik;

    Sammanfattning : Each day, we are confronted with a large amount of more or less important information that we have to consider, and even in our digital society we need paper for communication, documentation and education. Much of the paper we use or are confronted by in our daily life, such as newspapers, books and packages, contains printed images or texts, and the appearance of both the print and the supporting surface is important.

  2. 2. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Mikael Karlsson; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

    Sammanfattning : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. LÄS MER

  3. 3. 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.

  4. 4. 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

    Sammanfattning : The objects of this PhD thesis are Southern Swedish painted wall-hangings: folk art paintings from the 18th and 19th centuries. The aim and objective of the study are: to investigate the construction and manufacturing processes of the painted wall-hangings; to identify both the painting materials and other substances employed; and, to document painting techniques used by different painters within this painted wall-hanging tradition.
