Avhandlingen försvaras på svenska. © Katarina Karlström Stockholm 2009 Department of Fibre and Polymer Technology Teknikringen 56-58 SE-100 44 Stockholm Sweden Abstract Converting wood into paper is a complex process involving many different stages, one of which is pulping. Pulping involves liberating the wood fibres from each other, which can be done either chemically or mechanically. This thesis focuses on the most common chemical pulping method, the kraft cooking process, and especially on a recently developed improvement of the impregnation phase, which is the first part of a kraft cook. Extended impregnation kraft cooking (EIC) technique is demonstrated to be an improvement of the kraft pulping process and provides a way to utilize softwood to a higher degree, at higher pulp yield. We demonstrate that it is possible to produce softwood ( Picea abies ) kraft pulp using a new cooking technique, resulting in a pulp that can be defibrated without inline refining at as high lignin content as 8% on wood, measured as kappa numbers above 90. -

processes Review A Review on the Modeling, Control and Diagnostics of Continuous Pulp Digesters Moksadur Rahman * , Anders Avelin and Konstantinos Kyprianidis School of Business, Society and Engineering, Mälardalen University, Box 883, 72123 Västerås, Sweden; [email protected] (A.V.); [email protected] (K.K.) * Correspondence: [email protected]; Tel.: +46-(0)21-10-1594 Received: 12 August 2020; Accepted: 23 September 2020; Published: 1 October 2020 Abstract: Being at the heart of modern pulp mills, continuous pulp digesters have attracted much attention from the research community. In this article, a comprehensive review in the area of modeling, control and diagnostics of continuous pulp digesters is conducted. The evolution of research focus within these areas is followed and discussed. Particular effort has been devoted to identifying the state-of-the-art and the research gap in a summarized way. Finally, the current and future research directions in the areas have been analyzed and discussed. To date, digester modeling following the Purdue approach, Kappa number control using model predictive controllers and health index-based diagnostic approaches by utilizing different statistical methods have dominated the field. While the rising research interest within the field is evident, we anticipate further developments in advanced sensors and integration of these sensors for improving model prediction and controller performance; and the exploration of different AI-based approaches will be at the core of future research. Keywords: Kraft pulping; pulp digester; modeling; control; diagnostics 1. Introduction With the widespread expansion of the Internet, electronic media and paperless communication, the demand for the graphic paper (i.e., newsprint and higher-value printing and writing paper) has been declining since 2000 [1]. -
Technical Drawing: Selecting Your Paper
Published on L'atelier Canson (https://www.lateliercanson.com) Accueil > Technical drawing: Selecting your paper Retour à la liste d'articles [1] Technical drawing: Selecting your paper [2] Le matériel [5] Notez cet article Give Technical drawing: ? Selecting your paper 3/5 Taux Texture, format, thickness, grid: a wide range of paper, tracing paper and transparent film readily adapts to all your creations. 1. Grammage It conditions the paper's thickness and is measured as grams per square meter: fine papers (under 90 g/m²) are appropriate for sketching, intermediate (up to 200 g/m²), adapt to most kinds of work, thick (300 g and more) are designed for wet media such as watercolor. 2. Format It is standardized and comes in six formats: from A0 (1 (m)2), up to A5 (the smallest one). Each format represents half of the previous one. Most used are the two classics, A3 and A4. 3. Texture The quality of a technical drawing relies on perfect lines: opt for slightly textured paper, whether fine grained or satin finish, and even completely smooth, such as Bristol board. Memo: There?s a paper for every medium Graphite: white or slightly tinted (beige, ocher, gray?). Color pencils: fine grained to make the pigments hold. Markers: paper known as "layout" paper holds ink and limits smudges. 4. Graph paper Technical drawing implies high precision. Choose it taking your subject's constraints into account. White drawing paper and Bristol board are available as graph paper. The covers of "to scale" pads of tracing paper come as 5 mm grid charts. -

Este trabalho teve como objetivo avaliar a influência da adição de diferentes porcentagens de celulose nanofibrilada sobre as propriedades mecânicas e físicas do papel feito a partir da polpa de fibras curtas. A celulose nanofibrilada foi obtida a partir de polpa Kraft de Eucalyptus sp. branqueada, submetida a três diferentes passes no moinho: 2, 10 e 20 passes. Os papéis foram produzidos com a adição de celulose nanofibrilada nas porcentagens de 3, 6 e 9%. Os resultados mostraram que a adição de celulose nanofibrilada aumentou as propriedades mecânicas: índice de tração, índice de arrebentamento e índice de rasgo. A porosidade e a densidade aparente diminuíram. A adição de 9% de celulose nanofibrilada, obtida a partir de 2 passes, proporcionou os melhores resultados com aumento da resistência à tração, arrebentamento e rasgo de 111, 114 e 70%, respectivamente, em comparação aos papéis normais. A melhoria das propriedades mecânicas do papel está relacionada à rede muito densa de ligações de hidrogênio, resultando em maior área de superfície obtida após a desfibrilação. -

ISSN: 2395-3594 IJAET International Journal of Application of Engineering and Technology Vol-2 No.-3 Corrugated Board Structure: A Review M.C. Kaushal1, V.K.Sirohiya2 and R.K.Rathore3 1 2 Assistant Prof. Mechanical Engineering Department, Gwalior Institute of Information Technology,Gwalior, Assistant Prof. Mechanical Engineering 3 Departments, Gwalior Engineering College, Gwalior, M. Tech students Maharanapratap College of Technology, Gwalior, [email protected] [email protected] [email protected] ABSTRACT Corrugated board is widely used in the packing industry. The main advantages are lightness, recyclability and low cost. This makes the material the best choice to produce containers devoted to the shipping of goods. Furthermore examples of structure design based on corrugated boards can be found in different fields. Structural analysis of paperboard components is a crucial topic in the design of containers. It is required to investigate their strength properties because they have to protect the goods contained from lateral crushing and compression loads due to stacking. However in this paper complete and detailed information are presented. Keywords: - corrugated boards, recyclability, compression loads. Smaller flutes offer printability advantages as well as I. INTRODUCTION structural advantages for retail packaging. Corrugated board is essentially a paper sandwich consisting of corrugated medium layered between inside II. HISTORY and outside linerboard. On the production side, corrugated In 1856 the first known corrugated material was patented is a sub-category of the paperboard industry, which is a for sweatband lining in top hats. During the following four sub-category of the paper industry, which is a sub-category decades other forms of corrugated material were used as of the forest products industry. -
What Happens to Cellulosic Fibers During Papermaking and Recycling? a Review
PEER-REVIEWED REVIEW ARTICLE ncsu.edu/bioresources WHAT HAPPENS TO CELLULOSIC FIBERS DURING PAPERMAKING AND RECYCLING? A REVIEW Martin A. Hubbe,* Richard A. Venditti, and Orlando J. Rojas Both reversible and irreversible changes take place as cellulosic fibers are manufactured into paper products one or more times. This review considers both physical and chemical changes. It is proposed that by understanding these changes one can make better use of cellulosic fibers at various stages of their life cycles, achieving a broad range of paper performance characteristics. Some of the changes that occur as a result of recycling are inherent to the fibers themselves. Other changes may result from the presence of various contaminants associated with the fibers as a result of manufacturing processes and uses. The former category includes an expected loss of swelling ability and decreased wet-flexibility, especially after kraft fibers are dried. The latter category includes effects of inks, de-inking agents, stickies, and additives used during previous cycles of papermaking. Keywords: Paper recycling, Drying, Deinking, Hornification, Inter-fiber bonding, Refining, Fines, Fiber length, Conformability Contact information: Department of Forest Biomaterials Science and Engineering, Box 8005, North Carolina State University, Raleigh, NC 27695-8005, USA; *Corresponding author: [email protected] INTRODUCTION Cellulosic fibers can change significantly when formed into a wet web of paper and subsequently subjected to such processes as pressing, drying, printing, storage, repulping, and deinking. Some of the changes can be subtle. Often it is possible to substitute recovered fibers in place of virgin fibers used for the production of paper or paperboard. On the other hand, characteristic differences between recycled fibers and virgin fibers (fresh from pulping wood, not recycled) can be expected; many of these can be attributed to drying. -
