OIL HEAT TREATMENT OF WOOD
The investigation of thermal treatment of wood has led to the improvement of heat treatment with vegetable oils. The aim of this work has been to study the oil absorption …
BIOLOGICAL DURABILITY AND MECHANICALPROPERTIES OF HYDROTHERMALLY MODIFIED DECIDUOUS WOOD
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 …
CHANGES IN THE CHEMICAL COMPOSITION OF SOFT DECIDOUOUS WOOD AFTER THERMAL TREATMENT
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, …
DENDROLIGHT PANELS PRODUCED FROM ASPEN WOOD
Last years the reduced weight cell panel with the trade mark of Dendrolight has obtained the wide world identification due both opening new factory in Austria and intention to open …
WEAR PHASES OF CUTTING TOOL WHEN MILLING ASPEN WOOD
Investigations about wood cutting processes are mainly related to recognizing causes of wear of cutting tools and usually wood of conifers and hard deciduous trees have been used in cutting …
Wood modification efficiency evaluation with cyclic hydrothermal treatment
The decrease of water sorption is one of objectives of wood acetylation (Ac) with acetic anhydride (AA). The water absorption in acetylated wood might be decreased with rapeseed (Brassica napus) …
The effect of using densified low-quality veneers in plywood production as an alternative to birch plywood production
The growing demand for renewable raw materials, climate change and the sustainability of the circular economy force manufacturers to explore the use of new and underutilized wood species in wood …
Aspen plywood bonding characteristics with phenolic adhesives
As most plywood in Northern Europe is produced from either birch or different softwoods, or a combination of them, there is an interest to research other wood species for plywood …
Effect of Different Hardwood Species and Veneer Thickness on Bending and Density Properties of Plywood
Plywood is one of the most widely used wood-based product in the world and mainly produced from silver birch (Betula pendula Roth) tree. It is constructed by combining layers of …
Effect of Log Soaking on Colour of Estonian Hardwoods
Colour is an important property of veneer in furniture industry. Often the furniture companies struggle with the problem that the colour of veneer from the same species ordered from different …
Durability of the Printed Surface in the Sauna Environment
The use of digital printing creates added value for wood-based products, especially in terms of marketing. It allows them to be distinguished amongst the competitors and offer the customer the …
Wood Densification by Sodium Hypophosphite Impregnation and Mechanical Compression
The mechanical properties of wood are closely related to its density (Kollmann 1936). Increasing the density of low-density wood species is thus an attractive method to increase the value of …
Screw withdrawal capacity of aspen and black alder plywoods compared to birch plywood in 3 principal directions
Plywood is one of the most widely used wood-based panel product in the world. In plywood production the most common species like birch, spruce, poplar and pine are used. In …
