  2. 1. Heat and water transfer for lacquer drying and thermal signatures : modelling, simulation and experiment

    Author : Ricardo Garcia-Padron; Roland Wimmerstedt; Linköpings universitet; []
    Keywords : ;

    Abstract : The coupled phenomenon of heat and water transfer is essential in many scientific and industrial problems. This thesis focuses this phenomenon on two areas; lacquer drying and thermal signatures. Simulations of physical phenomena may in some cases replace extensive experimental investigations, which may be complicated and expensive. READ MORE

  4. 2. Plasma Modification of Polypropylene Materials for Improved Adhesion

    Author : Anna Nihlstrand; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polypropylene; characterization; material composition; lacquer adhesion; plasma modification; chain scission; vacuum-ultraviolet radiation; thermoplastic polyolefin;

    Abstract : Materials based on PP are widely used in industrial applications. To fulfil application demands, components must often be lacquered, printed or glued. As PP is highly unreactive and presents a low surface energy, a pretreatment that can promote bondability is necessary. READ MORE

  5. 3. Interaction and adhesion at the interface between wood and paint, glue, lacquer measured with DMTA and SEM

    Author : Anna Backman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Abstract : The aim of the present thesis was to study the interface between wood (Pinus sylvestis) and synthetic polymers such as glue, lacquer and paint. The weakest part of these interfaces is always the bond. The long-term properties of bonds between wood and an adherend are those which are interesting. READ MORE

  6. 4. Laccase from a Litter Degrading Fungus: Evaluation for Environmental Applications and Modification of Lignin to a Bioadhesive

    Author : Victor Ibrahim; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Laccase, the phenol oxidizing enzyme, was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes single electron transfer oxidation in the presence of molecular oxygen producing water as by-product.

  7. 5. Mechanical and physical properties of semi-isostatically densified wood

    Author : Jonas Blomberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Technology; Träteknik;

    Abstract : When wood is densified through semi-isostatical compression in a Quintus- press at pressures up to 140 MPa, the material properties change. The cells are flattened, size is decreased and shape is changed, as a consequence of this the density is increased. Most properties of native woods are strongly correlated to the density. READ MORE
