The study investigated the possibility of using rape straw and expanded polystyrene for the production of low density particleboards. Particleboards with the core layer made of wood chips or rape straw, partly substituted with polystyrene (7%), were manufactured within the density range of 500 -650 kg/ m 3 , and resinated with MUF resin. Our study confirmed that wood chip-expanded polystyrene (WP) and wood chip-rape straw-expanded polystyrene boards (WRP), of density reduced to 600 kg/m 3 , met the mechanical requirements of the subject standard for boards intended for interior design (including furniture) and used in dry conditions. However, further density reduction required an increased resination of the core layer.

“…In recent years, taking into account the latest reports, a number of experiments on the possibility of lowering the density of wood-based panels have been made [30][31][32][33]. The proposed changes often include the diversification of the lignocellulosic raw materials used, mainly in terms of the use of low-density raw materials, e.g., poplar wood, fast-growing wood, and lignocellulosic particles from biomass obtained in an annual cycle [12,[34][35][36][37]. Moreover, modifications of the technological parameters of the production process are proposed, mainly with regard to changes in the pressing curve [38] with the simultaneous injection of steam for a period of approx.…”

Low-Density Particleboards Modified with Expanded and Unexpanded Fillers—Characteristics and Properties

et al. 2022

Reducing the density of wood-based materials is a desirable research direction in the development of the wood-based materials sector. Even though lightweight wooden particleboards have been commercially available for many years, they still have a number of disadvantages, especially their low strength parameters. The aim of this paper was to determine the possibility of producing particleboards of reduced density for use in the furniture industry, as a result of using expanded polystyrene and two types of microspheres (expanded and unexpanded) to modify the core layer of three-layer particleboards. Analysis of the results of testing the particleboards’ properties when using various types of modifiers (expanded and unexpanded fillers), urea formaldehyde (UF) glue content (high: 10%/12% and low: 8%/10%), various glue-dosing methods, and different particle sizes, allows us to conclude that the most satisfactory effect was found when using EPS. One partly positive effect was observed when using the Expancel-type 031 DU 40 as a filler; therefore, it is recommended that research be continued in this area. Using microspheres that have not been used before as a filler in the production of wood-based panels is the novelty of the presented research. The proposed technology has potential for application in the industry.

“…The main advantage of new types of panels over the old ones is a lowered density. It is known from the literature that the density of woody material affects the compression ratio of a mat, which subsequently determines the properties of the final product (Buschbeck et al 1961a,b;Moslemi 1974;Grigoriu 1981;Clad 1982;Xu et al 2004;Haelvoet and Medved 2009). The reduced panel density renders a decrease in mechanical strength.…”

This study regards the effect of technological aspects on mat compression during the manufacturing of low-density particleboards made of two low density species -i.e. poplar and pine. Using these materials, three-layer low-density particleboards (500 kg/m 3 ) were prepared. Three series were manufactured: (1) neat pine, (2) poplar-pine (face layer and core layer, respectively) and (3) neat poplar boards. Measurements of real-time variations in mat core temperature, pressure, and mat thickness allowed for the analysis of the mat compaction. Selected mechanical properties (modulus of rupture, modulus of elasticity, and internal bonding) of the manufactured particleboards were determined. Raw material of lower density used for particleboard manufacturing required either prolonged pressing time or more intense heat transfer into the mat core. The highest strength values were obtained for the poplar-pine particleboards.
