Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The market for durable products using modified wood has increased substantially during the last few years. This is partly because of the restriction on the use of toxic preservatives due to environmental concerns, and to lower maintenance cost and time. Furthermore, as sustainability becomes a greater concern, the environmental impact of construction and interior materials is factored in planning by considering the whole life cycle and embodied energy of the materials used. Wood is modified to improve its intrinsic properties, enhance the range of applications of timber, and to acquire the form and functionality desired by engineers without calling the environmental friendliness into question. Wood modification processes are at various stages of development, and the challenges faced in scaling up to industrial applications differ. The aim of this book is to put together the key elements of the changes of wood constituents and the related changes in wood properties of modified wood. Further, a selection of the principal technologies implemented in wood modification are presented. This work is intended for researchers, professionals of timber construction, as well as students studying the science of materials, civil engineering and architecture. This work is not exhaustive, but intends to deliver an outline of the scientific disciplines necessary to apprehend the technologies of wood modification and its behavior during treatment, as well as during its use.

Download or read book Wood Properties and Processing written by Miha Humar and published by MDPI. This book was released on 2020-05-23 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood-based materials are CO2-neutral, renewable, and considered to be environmentally friendly. The huge variety of wood species and wood-based composites allows a wide scope of creative and esthetic alternatives to materials with higher environmental impacts during production, use and disposal. Quality of wood is influenced by the genetic and environmental factors. One of the emerging uses of wood are building and construction applications. Modern building and construction practices would not be possible without use of wood or wood-based composites. The use of composites enables using wood of lower quality for the production of materials with engineered properties for specific target applications. Even more, the utilization of such reinforcing particles as carbon nanotubes and nanocellulose enables development of a new generation of composites with even better properties. The positive aspect of decomposability of waste wood can turn into the opposite when wood or wood-based materials are exposed to weathering, moisture oscillations, different discolorations, and degrading organisms. Protective measures are therefore unavoidable for many outdoor applications. Resistance of wood against different aging factors is always a combined effect of toxic or inhibiting ingredients on the one hand, and of structural, anatomical, or chemical ways of excluding moisture on the other.

Download or read book Chemical Modification Properties and Usage of Lignin written by Thomas Q. Hu and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most significant challenges facing mankind in the twenty-first century is the development of a sustainable global economy. Within the scientific community, this calls for the development of processes and technologies that will allow the sustainable production of materials from renewable natural resources. Plant material, in particular lignin, is one such resource. During the annual production of about 100 million metric tons of chemical wood pulps worldwide, approximately 45 and 2 million metric tons/year of kraft lignin and lignosulfonates, respectively, are also generated. Although lignosulfonates have found many applications outside the pulp and paper industry, the majority of kraft lignin is being used internally as a low-grade fuel for the kraft pulping operation. A surplus of kraft lignin will become available as kraft mills increase their pulp production without expanding the capacity of their recovery boilers that utilize lignin as a fuel. There is a tremendous opportunity and an enormous economic incentive to find better uses of kraft lignin, lignosulfonates and other industriallignins. The pulp and paper industry not only produces an enormous amount of lignins as by products of chemical wood pulps, but it also utilizes about 10 million metric tons of lignin per year as a component of mechanical wood pulps and papers. Mechanical wood pulps, produced in a yield of 90-98% with the retention of lignin, are mainly used to make low-quality, non-permanent papers such as newsprint and telephone directories because of the light-induced photooxidation of lignin and the yellowing of the papers.
Download or read book Science of Wood Degradation and its Protection written by R. Sundararaj and published by Springer Nature. This book was released on 2022-03-16 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book covers all aspects of wood degradation from its formation and growing in trees to its end usages when it is put into human usage. Wood is an age-old traditional fascinating material with a sensory-rich immersive experience that kindles aesthetics and creativity. The utility, durability, and functionality of wood render it a cosmopolitan material. It constitutes an integral part of human lives from ancient times to modern societies being used by various sectors viz., construction, furniture, panel products, paper and pulp, sports goods, agricultural implements, etc., Wood, being a biological material, is susceptible to degradation both by physical and biological means, and the need to protect the wood and prevent heavy economic losses constitutes a major challenge. Also, wood formed by the trees is the major sinks of carbon and the carbon remains locked-up for the life of the wood, thereby serving as important tool to mitigate the climate change. But the carbon stored in wood returns to the atmosphere when it degrades and will have positive effect on climate change. Hence, wood protection aiming for extending the service life of wood plays a key role in locking the carbon for a longer period in the wood and also substantially reduce the demand and depletion of forest resources. The book focuses on wood as an important natural bio-resource, inventory of wood protection, usage, utilization, preservatives, protection technologies and wood protection from all forms of degradation. Special focus is given on the eco-friendly way of protecting wood and its importance in mitigating climate change. The book is useful for Indian and international readers, who are working in wood domains. It is of interest to wood technologists, teachers, researchers, climate change scientists, capacity builders, and policymakers. It is of immense importance as a guide and study material to the graduate and postgraduate students of wood science in various universities of India and abroad.
