Improvements in the Biological Durability of Uk Grown Timbers by Various Wood Modification Techniques
نویسندگان
چکیده
Results are also compared to EN350-1. Results to date indicate that furfurylation and acetylation are capable of improving the durability classification of UK grown Sitka spruce from Not Durable, Durability Class (DC) 5 for control samples to Very Durable (DC1). More interestingly, lower durability classifications were obtained when using UK grown Scots pine, where the treated samples could be regarded as Moderately Durable (DC3) or Slightly durable (DC4). Normally higher levels of modification would be expected for Scots pine compared to Sitka spruce. This may be due to a more effective envelope treatment with the Sitka spruce samples

As defined in BS EN 350-1 [1], natural durability is ‘the inherent resistance of wood to attack by wood destroying organisms’. Eaton and Hale [2] defined natural durability or decay resistance as the ability of the Heartwood of any wood species to resist decay. Normally, natural durability is measured by exposing the wood to biological agents such as termites, beetles, fungi and marine borers (...

Hydrothermal treatment of wood material products with many interesting properties such as enhanced dimensional stability, lower equilibrium moisture content and increased biological durability. The effects of hydrothermal treatment on dimensional stability, oven dry density and water absorption of beech wood (Fagus Orientalis) naturally grown, has been studied in present research that extremely...

Wood carving in various purposes and uniformly as an expression of art prevailed in every human society since the beginning of the Indus valley civilization or back to the centuries. It is closely attached to the different aspects of human life. A number of references can be traced in the civilization of Harappa that they used timbers to construct roofs of their abodes which were flat and made ...
متن کاملProperties of Wood and Wood Based Materials Subjected to Thermal Treatments under Various Conditions
Thermal modification is a well-known process to change the dimensional stability, hygroscopicity, and biological resistance of wood due to chemical modifications of wood cell components. In this study, we reviewed several characteristics of heat-modified solid wood and wood-based panels under various temperatures, durations and pressure. Thermal compressing treatment could affect drying speed, ...
متن کاملAcetylation of wood – A review
Wood is a porous three dimensional, hydroscopic, viscoelastic, anisotropic bio-polymer composite composed of an interconnecting matrix of cellulose, hemicelluloses and lignin with minor amounts of inorganic elements and organic extractives. Some, but not all, of the cell wall polymer hydroxyl groups are accessible to moisture and these accessible hydroxyls form hydrogen bonds with water. As the...
