Available in PDF, EPUB and Kindle. Book excerpt: "Applications of Wet-end Paper Chemistry" bridges the gap between the theory and practice of wet-end paper chemistry by explaining how particular chemicals are chosen and put to use in real situations. A number of international experts in the field present recent contributions on the optimum use of chemicals in papermaking. Major inroads have taken place since the first edition of this title was published in 1995. This new edition of "Applications of Wet-end Paper Chemistry" will reflect the changing type and use of chemicals used in papermaking in the 21st century. Chemists and chemical engineers across the paper and pulp making industry, as well as in research and academic institutes will find this book of enormous practical value.

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.

Available in PDF, EPUB and Kindle. Book excerpt: With the exception of a slight hiccup during the height of the recent environmental movement (during the early 1990s), when for a year or two consumers were prepared to pay a price premium for lower quality recycled paper than for the virgin product, the inexorable improvement in the quality demanded of paper products continues. This demand for quality covers not only the aesthetics ofthe product but also its performance. Moreover, it is becoming increasingly the case that papers designed for a particular use must, as it were incidentally, also perform well in alternative applications. An example is that of office and printing papers, which are expected to perform as well in copier machines as in all the various forms of impact and non-impact printers. But even greater demands are made in other product areas, where board designed for dry foods can also be expected to protect moist and fatty materials and be made of 100% recycled fibre. The need to isolate foodstuffs from some of the contaminants that can affect recycled board is a· serious challenge. Thus, papermakers are constantly striving to meet a broadening spectrum of demands on their products; often while accepting declining quality of raw materials. The product design philosophy that has arisen in response to this is increasingly to isolate the bulk of a paper from its uses: to engineer the needed performance characteristics into the paper surfaces while more or less ignoring what happens inside.

Download or read book Paper Chemistry written by J.C. Roberts and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 247 pages. 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 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 colloidal 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. As is the fashion these days, each chapter is written by an internationally recognised expert in the field, and my thanks are extended to all of the contributors. for their hours of patient and unseen research during the preparation of their manuscripts.

Download or read book The Chemistry of Paper written by J C Roberts and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The manufacture of paper involves a large amount of chemistry, including carbohydrate chemistry, pigments and resins and colloid and surface chemistry, as well as elements of environmental and analytical chemistry. Providing an overview of the making of paper from a chemical perspective, this book deals with both the chemistry of paper as a material and the chemistry of its production. The book explores several chemical processes involved in the production of paper: the delignification of the wood fibres performed at elevated temperature and pressure, the bleaching of the cellulose-rich pulp using environmentally-friendly systems, the formation of the pulp into sheets of fibres strengthened by extensive inter-fibre hydrogen bonding, and finally the coating of the sheets in a manner appropriate to their end use. This book is an informative and entertaining overview for students and others who require an introduction to the chemistry of paper manufacture.
