  1. 16. Enhancement of Phenol Formaldehyde Adhesive with Crystalline Nano Cellulose

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Johan Ekstrand; [2019]
    Keywords : Nano Cellulose; Fibrillated cellulose; Wood Adhesive; Shear strength; Adhesive Enhancement; Formaldehyde adhesive; Phenol Formaldehyde;

    Abstract : Abstract The wood industries to this day use almost exclusively petroleum derived adhesives that are based mainly on the reaction of formaldehyde with urea, melamine or phenol. These adhesives have low cost and good adjustable properties which makes it hard for bio-based alternatives to compete. READ MORE

  2. 17. Thermal and Mechanical Analysis of a Sustainable Alternative to Neoprene Wetsuits

    University essay from Lunds universitet/Industriell Produktion

    Author : Eric Holmström; Jakob Mattsson; [2019]
    Keywords : Wetsuit; Sustainability; Insulation; Thermal Conductivity; Elasticity; Technology and Engineering;

    Abstract : A novel material composition has been investigated in terms of thermal, mechanical, economical and sustainable aspects to be compared to neoprene wetsuits. It is believed that a sandwich structure produced by a dipping method with rubber layers containing an insulating textile can insulate better than foamed neoprene. READ MORE

  3. 18. Optimized utilization of raw materials for production of Cross Laminated Timber : Quality of laminations and its effects on mechanical properties of multi-layer panels

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Gustaf Lindstam; Beatrice Larsson; [2019]
    Keywords : ;

    Abstract : Cross laminated timber (CLT) is a product increasingly demanded by the market. This has led to an interest among producers to further optimize the use of raw material. READ MORE

  4. 19. Characteristics assessment of aspen logs used in the production of matches

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Joseph Adejo Umoru; [2018]
    Keywords : Non-destructive technique; resonance; stiffness; aspen; moisture content; basic density; cross sectional diameter area; bark width; grain angle; taper; sound velocity;

    Abstract : Aspen (Populus tremula L.) accounts for about 2% of the total wood stock in Sweden. Sawmills use only a small part (about 5,000 m³fub) of round wood aspen per year. Since there are no Swedish gradings and design values for aspen, no aspen is used for structural purposes. READ MORE

  5. 20. Finger-jointing of acetylated Scots pine using a conventional MUF resin

    University essay from KTH/Byggnadsmaterial

    Author : Christian Wincrantz; [2018]
    Keywords : Acetylated wood; Scots pine; juvenile wood; finger-jointing; mechanical properties modulus of rupture.;

    Abstract : Acetylation of wood is a modification technique that chemically alters the wood substance and enhances several properties of wood. The basic principle is to impregnate wood with acetic anhydride to react and replace OH-groups with acetyl groups in the wood cell wall. READ MORE
