  2. 16. Consolidation and Rheology at High Solids Content

    Author : Jerker Jäder; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : Paper and board are pigment coated in order to achieve a smooth surface, thereby enhancing the optical and printing properties. In the most frequently used technique, a metal blade is used for metering off the coating colour, which is typically applied by roll or jet application. READ MORE

  4. 17. 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

  5. 18. Characterization of selective solar absorbers : Experimental and theoretical modeling

    Author : Tuquabo Tesfamichael; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : This thesis deals with the preparation, optical characterization and analyses of experimental work and theoretical modeling on selective solar absorbers used in solar thermal collectors. The overall goal has been to obtain efficient absorbers by optimizing the optical properties, and to improve their durability using cost-effective techniques. READ MORE

  6. 19. Surface chemical behaviour

    Author : Marie Wickman; KTH; []
    Keywords : ;

    Abstract : The objective of the investigations included in this thesisis to show how the properties of alkyd resins, used as bindersin offset printing inks, affect the ink in terms of pigmentdispersion, emulsification of fountain solution, and inksetting.The interactions between alkyd resins and aqueous solutionshave been investigated by interfacial tension measurementsusing the pendant drop technique and by measurement of dropletsize using light diffraction.

    Abstract : The aim of this thesis work was to gain understanding of the interactions between talc mineral and surfaces, liquids and chemicals relevant for industrial applications, such as pulp and paper. Talc is used in the pulp and paper industry as a filler pigment, in control of pitch (lipophilic extractives) deposits and as a coating pigment. READ MORE
