Book Treatment of wood with siloxanes and metal micro particle deposition using plasma technology

Download or read book Treatment of wood with siloxanes and metal micro particle deposition using plasma technology written by Patricia Gascón-Garrido and published by Cuvillier Verlag. This book was released on 2017-10-06 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Assessing the Shelf Life Attributes of Mountain Pine Beetle killed Trees

Download or read book Assessing the Shelf Life Attributes of Mountain Pine Beetle killed Trees written by S. Magnussen and published by . This book was released on 2009 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2006, a total of 360 lodgepole pine trees were destructively sampled from 45 sites that had been killed by mountain pine beetle (Dendroctonous ponderosae Hopk.). The trees were sampled from the Sub Boreal Spruce (SBS) Biogeoclimatic zone within north central British Columbia. The trees were distributed evenly across the geographic areas as well as across a sample matrix that included three classes of time since death, three classes of diameter at breast height, and three classes of soil moisture regime. A previous report described the procedures used to the collect the data and summarized the data collected for each of the sample trees. The current study analyzes the data and presents a detailed assessment of the changes in the wood quality attributes of mountain pine beetle-killed trees that occur within 5 years since death.--Includes text from document.

Book Proposed Protocol for Evaluating Potential Strength reducing Characteristics in Lumber After a Catastrophic Event

Download or read book Proposed Protocol for Evaluating Potential Strength reducing Characteristics in Lumber After a Catastrophic Event written by Conroy Lum and published by . This book was released on 2009 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to develop a protocol for evaluating and responding to potential strength-reducing characteristics that develop in lumber from stands following a regional catastrophic event. This new protocol is intended to be distinct from the standardized lumber testing programs that are in place to support the development of structural design values. Under this two-year project, a general protocol has been drafted and a limited pilot study was undertaken to demonstrate its efficacy by using shake in post mountain pine beetle (MPB)-killed lodgepole pine lumber as an example. This protocol provides guidance on the identification of suitable characteristics for study, the design of an exploratory survey for assessing frequency of appearance, the approach for collecting samples for strength testing, the analysis of the test results, and, if necessary, the development of supplementary grading rules to respond to possible impacts to the lumber strength from these characteristics.--Document.

Book Addressing Marketplace Durability Issues with Post mountain Pine Beetle Lodgepole Pine

Download or read book Addressing Marketplace Durability Issues with Post mountain Pine Beetle Lodgepole Pine written by Anthony Byrne and published by . This book was released on 2005 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a compilation of three reports addressing market durability issues with products made from lodgepole pine that has been affected by mountain pine beetle (MPB) infestation. The first report describes the establishment of accelerated field tests to determine the decay resistance of blue-stained post-MPB lodgepole pine sapwood and non-stained sapwood with reference samples of Scots pine sapwood. The second is a comparative technical review of the nature of blue stain in post-MPB wood and the differences between blue stain, mould, and decay. The final report answers frequently asked questions about blue stain on Canadian wood products, including whether it affects construction-related properties.

Book Heat Disinfestation of Mountain Pine Beetle affected Wood

Download or read book Heat Disinfestation of Mountain Pine Beetle affected Wood written by Adnan Uzunovic and published by . This book was released on 2007 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Exporters of lumber and logs are obligated by Canadian law to apply approved treatments for phytosanitary purposes. Heating to 56°C for at least 30 minutes in a kiln or heating chamber (56/30) is the most common treatment used for lumber and is also an internationally accepted method to treat wood packaging in order to eradicate pests of concern. This time/temperature combination was originally developed to eradicate pinewood nematodes and their insect vectors. Questions have arisen in the marketplace about the efficacy of such treatment against fungal pests, and recently for those associated with mountain pine beetle-affected lodgepole pine. This project looked into the effectiveness of several time/temperature combinations, in particular whether 56/30 kills a selection of mountain pine beetle associated fungi including bluestain fungi (nine isolates), Ambrosiella fungi (three isolates) and sap-rot fungi (six isolates) ... Additionally, this project determined to what extent air-drying and wood aging reduced the viability of embedded fungi and if slow drying rendered the fungi more heat tolerant."--Document.
