  1. 1. Dewatering Cellulose Nanofibril Suspensions through Centrifugation

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Jennifer Astorsdotter; [2017]
    Nyckelord :Cellulose nanofibrils; Microfibrilated cellulose; Centrifugation; Dewatering; Fiber suspension; Cellulosa nanofibriller; CNF; Microfibrilerad cellulosa; MFC; Centrifugering; Avvattning; Fibersuspension.;

    Sammanfattning : Cellulose nanofibrils (CNF) is a renewable material with unique strength properties. A difficulty in CNF production is that CNF suspensions contain large amounts of water. If CNF suspension volume can be decreased by dewatering facilitated by centrifugation, then transportation costs and storage costs can be reduced. LÄS MER

  3. 2. Headbox Slice Opening Arrangement : A developed version and a new one

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Viktor Bergström; [2014]
    Nyckelord :Headbox; Slice opening; Base weight; Formation;

    Sammanfattning : The purpose of the headbox is to convert a flow of fiber suspension to a jet, with a thickness between 4 and 20mm and a width between 3 -8meters, depending on the paper machine model. To adjust the beam thickness, the lip adjustment arrangement is used. LÄS MER

  4. 3. Determination of Distribution of Fines in a Paper Structure using Fluorescence Microscopy- an introduction

    Kandidat-uppsats, Institutionen för kemi

    Författare :Weronica Rådberg; [2010]
    Nyckelord :;

    Sammanfattning : When making paper, fibers and additives are suspended in water to a fiber suspension. The sheet is formed by draining a specific amount of suspension through a wire-cloth. The procedure is well known, but the underlying mechanisms are not fully understood. LÄS MER
