The research presented examined wood treatment at high temperatures. Wood specimens were tested at an original working station. In order to increase the durability, environmental resistance and size and shape stability of wood products, the wood underwent a modification process. One modification method includedhigh-temperature heating (140–230°C). Exposure to heat contributed to changes in the chemical...
The sorption isotherms of Scots pine (Pinus sylvestris L.) wood were determined. The experiments were carried out for wood previously dried in industrial batch and progressive kilns according to various drying schedules. The experiments per-formed made it possible to determine the influence of different drying technologies,as well as parameters, on the sorption characteristics of kiln-dried Scots...
Modern nonwoven filter fabrics covered with a microfiber layer make it possible to carry out surface filtration. A dust cake forms only on their upstream side and influences the air flow resistance across the filter. The mode of formation of the flow resistance caused by such a fabric during the separation of very fine wood dust particles was the subject of a comparative investigation using a homogeneous,...
The paper presents a comparison of the density of seven provenances of spruce trees, grown on an experimental plot located at Siemianice Forest Experimental Station. This plot is a unique research area on which observations concerning the growth of spruce trees of different provenances have been conducted for 41 years. The conditions in which the trees grow are very similar and it may be assumed that...
Corrugated packaging production is currently facing the challenge to ensure a satisfactory strength of packaging despite the continuous increase in recycled paper as the main fibrous component. This research addresses a very common technical problem for the corrugated board industry – the difficulty of predicting the properties of paper products produced from heterogeneous sources. Grammage and structural...
The article presents the results of research on the influence of selected technological parameters, changed within a range similar to values presently used in industry, on the properties of three-layer particleboards produced from pine particlesobtained from sawmill waste. The particles were glued with amine resins. The panels, produced using urea-formaldehyde resin modified with melamine, were characterisedby...
The paper deals with the cutting of agglomerated materials with an abrasive water jet from the point of view of surface finish undulation. It shows the impact on undulation of technical and technological parameters (feed rate and abrasive mass flow) and material parameters (material thickness and cutting direction). The paper also contains a methodology for the assessment of the effect of these parameters...
The aim of the article is to identify the various types of network structures occurring in the furniture industry from the perspective of the industrial network approach, using Poland as an example. The conceptual framework of this article, which comprises the industrial network approach and Actors-Resources-Activities model, together with a secondary sources analysis, is adopted in order to identify...
The paper presents the results of chamber tests conducted on UV-cured water-based lacquer coatings applied on different wood species. Volatile organic compounds were transferred onto Tenax TA and then they were assayed by gas chromatographycoupled with mass spectrometry and thermal desorption. It was found thatUV-cured water-based coatings may be potential sources of the emission of volatile substances...
The study presents the hydrophobic effect of silane-modified protective systems on wood resistance to aging factors (water and UV radiation). This paper is focusedon conventional and low VOC emulsion systems for exterior use, which wereimproved with silanes such as methyltrimethoxysilane (MTMOS), aminoethylaminopropyltrimethoxysilane (AEAPTMOS) and glycidoxypropyltrimethoxysilane(GPTMOS). The performance...
The purpose of the conducted experiment was to learn about the influence of composts obtained from post-consumer wood on the growth, flowering and nutrition of the canna lily (Canna x generalis L.H. Bailey)‘Tropical Yellow’. The number of microorganisms and the level of their enzymatic activity in the media in which the plants were cultivated were also examined. Two variants of composts made from...
