The use of beech particles in the production of particleboards based on recycled wood
Original language description
Some manufacturers of agglomerated materials also have sawmill processing within one plant, where waste (sawdust, cuttings, ...) is generated and can be used to manufacture agglomerated materials. Our goal in this article would be to point out the use of waste in manufacturing beech wood to produce particleboard. The properties of particleboard made of standard spruce particles with max. 20% addition of recycled wood and with 10, 20 and 30 % of beech wood particles were evaluated. In laboratory conditions, a three-layer particleboard was produced at a temperature of 240 oC, a maximum specific pressing pressure of 5.24 MPa, and a pressing factor of 8 s/mm. Selected physical (moisture, density, (density profile), thickness swelling (TS), and water absorption (WA), after 2 and 24 h) and mechanical properties (internal bond, modulus of rupture, modulus of elasticity in bending, surface soundness) of the manufactured particleboard were determined. The individual physical and mechanical properties of the manufactured particleboard were compared between individual variants with different proportions of beech particles and standard requirements. The presence of beech particles positively affected moisture properties (decrease in the range TS 24h of 25% or WA 24h of 32 % and some mechanical properties such as internal bond and surface soundness. The bending properties were negatively affected (decrease in the range of 11%), in which the bending strength did not reach the specific requirements of P2-type particleboard.
