  1. 1. Coated Norway Spruce Influence of Wood Characteristics on Water Sorption and Coating Durability

    University dissertation from Växjö : Linnaeus University Press

    Author : Tinh Sjökvist; Linnéuniversitetet.; [2019]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Heartwood; Sapwood; Wood extractives; Moisture content; Paint; Alkyd; Acrylic; Linseed oil; Calcimine paint; Mould; Fungi; Algae; Weathering; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Wood used outdoors is often degraded and discoloured by microorganisms as a natural part of its life cycle, particularly when exposed to high levels of moisture for prolonged times. In this case, the application of a coating (i.e. paint) is an option for increasing the service life of the wood. READ MORE

  2. 2. Improved properties of thermoplastic wood flour composites

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Kristiina Oksman; Luleå tekniska universitet.; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites; Träteknik; Wood Technology;

    Abstract : In this study the properties of composites made of wood flour and thermoplastics have been investigated. In order to improve the interfacial adhesion between hydrophobic and nonpolar thermoplastics and hydrophilic and polar wood flour different additives have been used as compatibilizers in composites systems.

  3. 3. Diffusive Mass Transport of Ions in Wood

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Reddysuresh Kolavali; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption; wood; mass transport; impregnation;

    Abstract : Understanding the conditions that control the mass transfer of various chemicals/ions in wood is of great importance when it is subjected to various processes. Homogeneous impregnation with chemicals/ions, for example, increases the uniformity of the treatments to which the wood is subjected, reduces reaction times and may increase the yield of the final products.

  4. 4. Extrusion processing of wood raw materials for use in wood-polymer composites

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Maiju Hietala; Luleå tekniska universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Abstract : The interest in wood-polymer composites and their use in different applications has been growing over the last 10-15 years. Environmental issues and demands on lower material costs are the driving forces behind the increasing use of renewable materials such as wood and other natural fibres as reinforcement in polymer composites.

  5. 5. Extrusion processing of wood-based biocomposites

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Maiju Hietala; Luleå tekniska universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Abstract : Interest in biocomposite materials and their use in various applications has been growing steadily over the past 10-15 years. Increasing environmental awareness and lower material costs are the main driving forces for using renewable materials, such as wood and cellulose fibers, as reinforcement in polymer composites.
