Properties of particleboard composed of recycled wood particles bonded by suberinic acids

The data set represents results of experimental particleboards produced of sawdust bonded with natural suberinic acids (SA) mixture obtained from birch outer bark. The data set is generated from results of tested particleboard properties summarized in 5 Excel files. Each file consists of multiple worksheets representing experimental data of each particleboard sample and a 'Description' worksheet which provides a concise description of the methods used to obtain the data and the abbreviations used throughout the file. In addition, a descriptive PNG file is included representing a scheme of particleboard cutting to individual specimens for each property testing. Ten particleboards samples (No 9. 10, 11, 12, 13, 21, 22, 31, 32, 33) were produced from recycled particleboard particles supplied by the local particleboard manufacturer Kronospan Latvia, varying density and pressing parameters defined in the table below. The furnish of recycled particles consisted of fine (< 2 mm) and coarse (55% > 2 mm) fractions formed in face and core layers, respectively. 15–21 wt.% (dry basis) of wet SA binder was added to the supplied particles. The blended furnish was then dried to a moisture content < 2%, and hot-pressed at varying the temperatures (200–220 ℃) and pressing times (0.9–1.5 min/mm) to obtain the particleboards with final dimensions of 9 mm × 310 mm × 310 mm, and a target density ranging from 650 to 750 kg/m3. Three particleboard samples (No 11, 12, 13) were made with final dimensions of 7 mm × 160 mm × 190 mm.

The obtained particleboards were characterized according to the relevant standards by determining density (EN 323), modulus of elasticity (MOE) and modulus of rupture (MOR) in a three-point bending test (EN 310), tensile strength perpendicular to the board surface (IB) (EN 319), thickness swelling and water absorption (TS/WA) after 24 h immersion in water (EN 317), and face withdrawal of screw resistance (WSR) (EN 320). Mechanical tests (MOE, MOR, IB, FWS) were performed using a ZWICK/Roell Z010 (Ulm, Germany) universal machine. The data set contains the following files: 1. Specimen cutting scheme.png 2.
