Rationalising the resources and widening the use of wood materials in construction and living environment corresponds to the climate-neutral economy goals. Wood resources that mainly consist of juvenile or core …
Many materials are exposed to degrading outdoor conditions during their use phase as products in construction, automotive, packaging, textiles, consumer goods and also when they are managed irresponsibly as waste …
Wood finishing with coatings can have protective, aesthetic, or both functions depending on the intended application. Reduction of the adverse effects of water and photodegradation is the most common idea …
The implementation of the Biocide Products Directive and the impact of public opinion are the main reasons for dramatic changes in the field of wood preservatives. The new generation preservatives …
For many years, biocides (mainly copper chromium arsenic (CCA) water-based solutions, containing toxic heavy metals – copper (Cu), chromium (Cr) and arsenic (As)) have been used for protection of wood. …
Studies of the physical and chemical properties of soft deciduous wood, namely, grey alder (Alnus incana) in thermal modification (temperature 140-180oC, water vapour medium) are carried out. Changes in the …
In the moderate climatic zone, in which also Latvia is located, mainly coniferous wood is used in construction, whose properties are more appropriate for load-carrying and bearing structures. The stock …
Thermal treatment is one of the most promising methods for upgrading wood durability properties. In the hydrothermal modification process, not only the chemical properties and structure of wood are changed, …
Wooden roof shingles were made from pine (Pinus sylvestris L.) and spruce (Picea abies (L.) Karst.). The natural durability of those wood species is classified as class 4 (non-durable). To …
Outdoors, wood degrades due to weathering from factors such as solar radiation (ultraviolet, visible and infrared light), water (rain, dew, snow, humidity), temperature and atmospheric pollution (sulphur dioxide, nitrogen dioxide, …
Ash-tree wood is heavy, tough and durable; hence, it belongs to hard deciduous wood species. In comparison with oak, ash-tree is more fast-growing; it reaches a height of 20 m …
In this work, a set of solvent-borne coatings for wood protection and finishing, 7 industrial and 2 experimental, was studied to verify their performance and the effects of artificial weathering. …
In this experiment a set of wood samples has been hydrothermally modified and then coated, to test their performance during outdoor exposure. The aim of this work is to evaluate …
The following hardwood species were used for heat treatment: birch (Betula pendula) and grey alder (Alnus incana). Modification was carried out in a multi-functional pilot device WTT in elevated water …
During the last decades several processes of wood thermal modification have been developed and obtained material properties investigated. By comparison only a few researches are devoted to environmental impact of …
