Book Description
Wood products used in exterior applications must be protected against biodeterioration. Traditionally, wood products used CCA or the older inexpensive organic biocides, but environmental, disposal and governmental regulations have resulted in a rapid and dramatic worldwide shift. This book covers the many steps involved in developing a wood preservative and gives overviews on modified wood, wood deterioration, worldwide trends in wood protections, and mold in homes.

Book Description
An in-depth examination of deterioration caused by fungi and other microorganisms, Wood Microbiology explores the major damages to wood and wood products during growth, harvesting, storage, and conversion to finished lumber. The characteristics, causes, detection, effects, and control measures for wood damage are stressed. - Reviews characteristics, classification, and metabolism of fungi responsible for wood deterioration and discoloration - Examines the anatomical, structural, and chemical features of decay - Covers effects of decay on physical and structural properties of wood - Presents methods for preventing biodegradation and for preserving wood - Extensively classroom tested--suitable for a two-quarter or one-semester course - Each chapter contains a summary and detailed references

Book Description
Drying Hardwood Lumber focuses on common methods for drying lumber of different thickness, with minimal drying defects, for high quality applications. This manual also includes predrying treatments that, when part of an overall quality-oriented drying system, reduce defects and improve drying quality, especially of oak lumber. Special attention is given to drying white wood, such as hard maple and ash, without sticker shadow or other discoloration. Several special drying methods, such as solar drying, are described, and proper techniques for storing dried lumber are discussed. Suggestions are provided for ways to economize on drying costs by reducing drying time and energy demands when feasible. Each chapter is accompanied by a list of references. Some references are cited in the chapter; others are listed as additional sources of information.

Book Description
This book is exclusively concerned with wood modification, although many of these processes are generic and can be applied to other lignocellulosic materials. There have been many rapid developments in wood modification over the past decade and, in particular, there has been considerable progress made in the commercialisation of technologies. Topics covered include: The use of timber in the 21st century Modifying the properties of wood Chemical modification of wood: Acetic Anhydride Modification and reaction with other chemicals Thermal modification of wood Surface modification Impregnation modification Commercialisation of wood modification Environmental consideration and future developments This is the first time that a book has covered all wood modification technologies in one text. Although the book covers the main research developments in wood modification, it also puts wood modification into context and additionally deals with aspects of commercialisation and environmental impact. This book is very timely, because wood modification is undergoing huge developments at the present time, driven in part by environmental concerns regarding the use of wood treated with certain preservatives. There has been considerable commercial interest shown in wood modification over the past decade, with products based upon thermal modification, and furfurylation now being actively being marketed. The next few years will see the commercialisation of acetylation and impregnation modification. This is a new industry, but one that has enormous potential. This book will prove useful to all those with an interest in wood modification including researchers, technologists and professionals working in wood science and timber engineering, wood preservation, and well as professionals in the paper and pulp industries, and those with an interest in the development of renewable materials.

Book Description
NOTE: NO FURTHER DISCOUNT FOR THIS PRINT PRODUCT-- OVERSTOCK SALE -- Significantly reduced list price Wood preservatives are generally grouped into two categories: preservatives used for in-place field (remedial)treatment and preservatives used for pressure treatments.A limitation of in-place treatments is that they cannot beforced deeply into the wood under pressure. However, theycan be applied into the center of large wooden membersvia treatment holes. These preservatives may be availableas liquids, rods, or pastes. Pressure-treated wood has muchdeeper and more uniform preservative penetration thanwood treated with other methods. The type of pressuretreated wood is often dependent on the requirements of thespecific application. To guide selection of pressure-treatedwood, the American Wood Protection Association developedUse Category System standards. Other preservative characteristics, such as color, odor, and surface oiliness may alsobe relevant. Guidelines for selection and application of fieldtreatments and for selection and specification of pressure-treated wood are provided in this document.

Book Description
In recent years considerable progress has been made in elucidating wood decay mechanisms. This basic knowledge not only has the potential to develop alternative environmentally-benign wood preservatives, but may also impact other areas such as bioremediation and pulp and paper. This book will summarize the latest knowledge of the developments, potential impacts, and applications from some of the world's leading experts.

Book Description
Plasma treatment is a novel and promising technolgy in the field of wood surface modification. Deposition of micro-particles on wood surfaces by means of plasma is an interesting approach to enhance wood properties and thus, to extend the service life of wood products. On the other hand, several silicone fomulations have been already shown to cause excellent water repellence and interaction with cell wall components, beside to impart high chenical and weathering stability as well as biological resistance in treated wood. Based on that, this study focussed on both treatments seperately in an initial stage of the research; followed by the combination, in a two-step treatment, of vacuum-pressure impregnation of solid wook with siloxanes and additional copper deposition on wood surface using atmostpheric pressure plasma.
