Protection And Preservation Of Wood In Service

Wood is an advantageous building material in many respects, but it is biodegradable and therefore requires protection when used in highly hazardous applications. This Special Issue comprises 19 papers by authors from 14 countries in Asia, North America and Europe. They represent a wide range of aspects related to wood protection and wood preservation, and give timely examples of research activities that can be observed around the globe. Several authors reported on the processes of thermal modification and different chemical wood modification techniques, which are among the latest alternative wood protection methods without the use of biocides. New preservatives and assessment methods of preservative-treated wood products are presented, as well as studies on the natural durability of wood, fire-retardant treated wood, the effect of concrete on wood durability and different novel surface modification techniques using plasma. In addition to biological durability, the mechanical properties, moisture performance, bonding properties, weathering stability and the corrosiveness of differently treated wood are investigated and reported within this Special Issue. Examples of research on fungal biology, service life planning with wood and test methodology are also included and complete the Special Issue.

The new edition of this comprehensive study of national and international research and application into wood preservation is both well detailed and broad in coverage. The text covers the history of preservation: the anatomy of timbers and their breakdown, preservation principles, materials and methods.

Wood preservation is the pressure or thermal impregnation of chemicals into wood to a depth that will provide effective long-term resistance attack by fungi, insects, and marine borers. The chemical predominantly used in Canada for wood preservation are pentachlorophenol, creosote, and aqueous formulations of arsenic, copper, chromium or ammonia. The wood preservation process deposits or fixes these chemicals in the wood, and the toxic nature of the chemicals effectively prevents the attack of living organisms on the wood. Because the chemicals are also toxic in varying degrees to humans and aquatic organisms, their use in industry must be carefully controlled. This document is intended to provide consistent guidelines for the design and operation of wood preservation facilities in a manner that will protect workers and the environment from harmful exposure to wood preservation chemicals.

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.
