Properties of Experiemntal Panels Made from Mixture of Dolomite and Olivine with Calabrian pine Wood Particles. Part 1. Physical properties

The effects of two mineral adducts (dolomite and olivine) as proportion in Calabrian pine wood chip based-experimental panels which bonded with synthetic adhesive (UF) were evaluated. It appears both minerals (P: calabrian chip-, X: Dolomite- Y: Olivine composite proportions) improve the water repellent efficiency (WRE) properties at certain extent. In all experimental procedure, WRE increased dolomite olivine proportions higher than >10% board formulations. highest -34.2% -35.4% found PX5 PY5 samples that made 1:1 (w/w) dolomite/wood olivine/wood formulations, respectively. Like sorption, similar trend was also for thickness swelling (TS) properties. lower TS values to be range -11.2 -56.4% dolomite-, -55.5 -69.5% based panels, Only PX1, produced 1:9 chips (w,w, %) proportions, show IB value control (PX0: 0.87 MPa vs PX1: 0.99 MPa) while rest dolomite- values. contrast dolomite, appear improving on conditions. 1.21 sample PY4, 4:6 indicate approximately 39.1% control. is notable seems more effective properation formulations terms lowering TS, WA creating internal bond strength However, only PY1, (w, w,%) bending (13.27 elasticity (2468.2 (PY0:12.75 2245.2 MPa).
