Abstract
The impact of the share of waste lignocellulosic biomass from apple orchards on the susceptibility to drilling of produced particle boards. Every year, care cuts are carried out in the orchards, which result in a significantamount of waste. This waste is a valuable source of lignocellulosic material for particleboards production. As part of this study, the influence of the share of waste apple wood on the susceptibility to drilling of particleboards was investigated. Three-layer particle boards with share of lignocellulosic waste biomass from apple orchards (0%, 25%, 50% and 75%) and density level at 650 kg/m3and 550 kg/m3 were made. The particleboards were examined for the axial force and torque that occurs during drilling. The highest value of the axial force during drilling was notice for particleboard without apple wood and a density of 650 kg/m3. While the lowest axial force during drilling was recorded for particleboard with 50% share of apple wood and density of 550 kg/m3. The obtained results allow to conclude that density of the produced particleboards and the share of apple wood waste have a statistically significant effect on the axial force during drilling. While the share of apple wood do not statistically affect the torque during drilling. In the case of the pressing unit pressure used in the particleboards production process, no statistically significant influence on the axial force and torque during drilling was found
