wood modification and weathering

Photodegradation of thermally modified wood - ScienceDirect

05/12/2012 In order to protect wood from such degradation the chemical structure of wood is altered by chemical modification or heat treatment. In the present study heat treated specimens of rubberwood (Hevea brasiliensis) were exposed to xenon light source in a weather-o-meter for different periods up to 300 h. Photostability of modified and unmodified wood was evaluated in terms of colour and chemical changes.Cited by: 102【Get Price】

Hybrid Approach for Wood Modification: Characterization ...

Wood as a biological material is sensitive to environmental conditions and microorganisms; therefore wood products require protective measures to extend their service life in outdoor applications. Several modification processes are available for the improvement of wood properties including commercially available solutions.Cited by: 1【Get Price】

Wood Modification Effects on Weathering of HDPE-Based Wood ...

18/04/2009 Wood Modification Effects on Weathering of HDPE-Based Wood Plastic Composites WPCs were produced from pine extractives-free pine and pine holocellulose fibers (60%) together with HDPE (40%). These composites were subjected to xenon-arc accelerated and outside weathering for a total of 1200 h and 120 days respectively.【Get Price】

What is Modified Wood? - reSAWN TIMBER co.

Chemical Modification of Wood – AcetylationChemical/Thermal Modification of Wood – FurfurylationCharred Modification Process – Shou Sugi BanTypically a process called acetylation is used to achieve chemically modified wood. Acetylation is a chemical reaction that has been used for over 100 years. The process subjects vinegar to a softwood which turns it into a hardwood by preventing the cells in the wood from being able to absorb water. The physical properties of any material are determined by its chemical structure. Wood contains an abundance of chemical groups … 【Get Price】

3 Ways to Weather Wood - wikiHow

21/05/2011 Weathering wood also called aging or distressing is a process where new wood is made to look old or worn. Weathering is especially important when you need to replace a piece of wood in an old structure or if you're trying to give a new woodworking project an antique feel.75%(8)【Get Price】
