Download or read book Applications of Wet End Paper Chemistry written by Che On Au and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Commercial demands and increasing global competition have led to enormous mechanical evolution over recent years. Twin-wires, wide-nip presses, steam boxes and speed sizers have all played a part in improving both the productivity and quality of paper and board products. With the emphasis on mechanical and electrical engineering and the ever increasing pressures of quality measurement and control, little time has been available within a technical department for much reflection on the chemistry of the process. Thus there is a growing trend for the management of the wet-end to be delegated to the chemical supplier. The advances in scale of paper manufacture, environmental sensitivity and higher quality of end-product requirements have all had an impact on the chemistry of the wet-end. The increased production means, for example, that down time is more of an anathema now when capacity is critical. Similarly, with the greater rigours of quality management, anything which causes breaks or holes must be eradicated. Environmental pressures too are growing on the papermaking process. Even if consideration is restricted to only the closure of the white water circuit, it alone throws down a challenge to the potency of biocides, retention aids and other chemicals. These chemicals are detriment ally affected by an increasing concentration of water soluble pulp extractives and surfactants, adhesives and polysaccharides from broke and recycled paper.

Download or read book The local distribution of fillers in the z direction of paper written by Christian Rompf and published by diplom.de. This book was released on 2014-04-11 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Introduction: It is important to determine the distribution fillers in thickness direction of paper. However, the techniques that are available are limited in precision and accuracy. This thesis describes a new method for the determination of fillers in the z-direction of paper. The method is based on a splitting technique that offers a good reproducibility and provides good layer uniformity. The new method is used to estimate the effects of different factors of influences affecting the fillers distribution. During sheet forming a large amount of water is removed. This dewatering process creates an irregular distribution of fillers across the thickness of the paper. Therefore, the description of the distribution of fillers in the thickness direction is critical to optimize paper properties. The techniques currently available for this kind of characterization have limitations in terms of repeatability, resolution or precision. Another limitation to currently available techniques is the lack of a good sampling area. Considering the large effect of fillers on many paper properties, the ability to measure and thus control the filler distribution in the z-direction helps to control sheet structure, reduce two-sidedness and improve paper properties such as internal bond.

Available in PDF, EPUB and Kindle. Book excerpt: Papermaking is a fascinating art and technology. The second edition of this successful 2 volume handbook provides a comprehensive view on the technical, economic, ecologic and social background of paper and board. It has been updated, revised and largely extended in depth and width including the further use of paper and board in converting and printing. A wide knowledge basis is a prerequisite in evaluating and optimizing the whole process chain to ensure efficient paper and board production. The same is true in their application and end use. The book covers a wide range of topics: * Raw materials required for paper and board manufacturing such as fibers, chemical additives and fillers * Processes and machinery applied to prepare the stock and to produce the various paper and board grades including automation and trouble shooting * Paper converting and printing processes, book preservation * The different paper and board grades as well as testing and analysing fiber suspensions, paper and board products, and converted or printed matters * Environmental and energy factors as well as safety aspects. The handbook will provide professionals in the field, e. g. papermakers as well as converters and printers, laymen, students, politicians and other interested people with the most up-to-date and comprehensive information on the state-of- the-art techniques and aspects involved in paper making, converting and printing.

Available in PDF, EPUB and Kindle. Book excerpt: Although the title of this book is Paper Chemistry, it should be considered as a text about the chemistry of the formation of paper from aqueous suspensions of fibre and other additives, rather than as a book about the chemistry of the raw material itself. It is the subject of what papermakers call wet-end chemistry. There are many other excellent texts on the chemistry of cellulose and apart from one chapter on the accessibility of cellulose, the subject is not addressed here. Neither does the book deal with the chemistry of pulp preparation (from wood, from other plant sources or from recycled fibres), for there are also many excellent texts on this subject. The first edition of this book was a great success and soon became established as one of the Bibles of the industry. Its achievement then was to collect the considerable advances in understanding which had been made in the chemistry of papermaking in previous years, and provide, for the first time, a sound physico chemical basis of the subject. This new edition has been thoroughly updated with much new material added. The formation of paper is a continuous filtration process in which cellulosic fibres are formed into a network which is then pressed and dried. The important chemistry involved in this process is firstly the retention of col loidal material during filtration and secondly the modification of fibre and sheet properties so as to widen the scope for the use of paper and board products.
