Abstract
This work explores some technological properties of three-layer particleboard produced from pine (Pinus Pinea L.) wood particles and waste cones. Four board types were made from mixtures of wood particles/stone cone (100/0, 50/50, 0/100 and 40/60%, respectively). The laying ratio (outers: core) was 40:60%. The particleboards were manufactured with a board density of 700 g/cm3, board size of 400×400×12 mm and a pressing pressure of 24-26 kPa/cm2. The limiting oxygen Index (LOI) levels (ASTM D 2863), decay resistance (EN 113) and surface roughness (DIN 4768) of particleboards were determined. The using stone cone was found to be affecting all the properties of particleboards. The result showed that using waste cone increased the decay resistance. However, LOI values and surface roughness of the panels increased with increasing the pine cone amount of mixture.
