  1. 11. Pulp compositions and their influence on the production of dialcohol cellulose

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Viktoria Carlsson; [2020]
    Keywords : ;

    Abstract : The characteristics of products made from pulp can be modified through different methods. If the pulp is refined either laboratory or industrially, the fibres in the pulp become more flexible and therefore creates stronger bonds to each other, which results in a final product with a higher strength.

  3. 12. Modified lignin as replacement of carbon black in elastomers- For the development of sustainable tyre technology : The substitution of carbon black with modified lignin- Green tyre technology

    University essay from Karlstads universitet/Avdelningen för kemiteknik

    Author : Mostafa Ahmed Ismail; [2020]
    Keywords : lignin; tyre rubber; elastomeric materials; esterfication;

    Abstract : Due to its large flexibility, low-price, large availability, and properties lignin is seen as an important compound with a wide range of applications. The increasing demand of fossil-based rubber materials is causing a serious threat to the environment and it is contributing to plastic- and marine pollution, ozone depletion and carbon dioxide emission (CO2) [1,2].

  4. 13. Development of a Profile Sample Cutter

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Maryam Tarik Hamad; [2020]
    Keywords : Blade geometry; vertical constraint; paper properties; paper slitting; Knivbladsgeometri; vertikal begränsning; pappersegenskaper; pappersskärning;

    Abstract : The pulp- and paper industry is a key industry globally and stands for a production of 600 million tonnes pulp and paper worldwide with a total revenue of 400 billion dollars. Due to high quality requirements on paper, it is important to use instruments that control that the produced paper fulfill the promised requirements. READ MORE

  5. 14. Transparent paper: Evaluation of chemical modification routes to achieve self-fibrillating fibres

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Paulina Sandberg Birgersson; [2020]
    Keywords : Transparent paper; nanopaper; nanocellulose; chemical modification of cellulose; cellulose nanofibrils CNF ; Transparent papper; nanopaper; nanocellulosa; kemisk modifiering av cellulosa; cellulosa nanofibriller CNF ; nanopapper;

    Abstract : Transparenta papper tillverkade av cellulosa nanofibriller (CNF), visar stor potential att kunna ersätta petroleumbaserade plaster inom många användningsområden, till exempel för mat- och varuförpackningar. CNF, även känt som nanocellulosa, kombinerar viktiga cellulosaegenskaper, med unika egenskaper hos nanomaterial. READ MORE

  6. 15. Effects of processing techniques on the microstructure of renewable pulp-fiber reinforced composites and their mechanical performance

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Predrag Jagunic; [2018]
    Keywords : composites; mechanical performance; microstructure; renewable; processing techniques;

    Abstract : Commingled composites are stronger than those manufactured with the standard manufacturing method. The objective of the thesis is to answer why that is, to investigate the microstructure of the composites, to model composite strength and compare experimental values with theoretical for composites having poly lactic acid (PLA) as matrix material and composites having poly propylene (PP) as matrix material.
