Özet:

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

 Çalışmada, kızılçam odun yongalarından sentetik tutkal üre-formaldehit kullanılarak hazırlanan deneme levhalarına, farklı oranlarda iki mineral madde ilavesinin etkisi araştırılmıştır Kompozit içeriğinde; P: Çam odun yongası, X: Dolomite Y: Olivine olduğunu belirtir. Mineral ilavesinin, levhaların su itici özelliklerini belli derecede iyileştirdiği belirlenmiştir. Tüm deneme şartlarında, 10 ve daha fazla dolomit ve olivin ilave edilmiş levhaların su itici özellikleri yükselmiştir. En yüksek su itici özellik iyileştirmesi; 1:1 ağırlıkağırlık dolomitodun ve olivinodun ile formüle edilmiş PX5 ve PY5 örneklerinde -34.2 ve -35.4 olarak elde edilmiştir. Su absorpsiyonuna benzer eğilim, örneklerin kalınlık artım özelliklerinde de gözlemlenmiştir. En yüksek kalınlığına artım iyileşmesi  -11.2 ile -56.4 dolomit ileve edilmiş levhalarda, -55.5 ile -69.5 olivin ielave edilmiş levhalarda bulunmuştur. Sadece 1:9 dolomitodun yongası karışımından ağırlıkağırlık,  üretilmiş PX1 deneme numunesinde, kontrol örneklerinden PX0: 0.87 MPa; PX1: 0.99 MPa daha yüksek yüzeye dik çekme direncine IB ulaşılmış, diğer tüm levhaların yüzeye dik çekme dirençleri, kontrollerden daha düşük bulunmuştur. Dolomitten farklı olarak, olivin ilavesinin levhaların yüzeye dik çekme direncine bazı şartlarda olumlu katkı sağladığı anlaşılmıştır. Olivin ilaveli levhalarda, en yüksek yüzeye dik çekme direnci, 1.21 MPa olarak 4:6 olivinodun yongası ağırlık, ağırlık,  oranıyla üretilmiş PY4 örneğinde hesaplanmış ve bu değer, kontrol örneğinden yaklaşık 39.1 daha yüksek bulunmuştur. Olivin, dolomite göre benzer odun-mineral madde formülasyonlarında su içinde kalınlık artımı ve su absorpsiyonuna karşı daha etkili olduğu ve daha yüksek yüzeye dik çekme direnç sağladığı gözlemlenmiştir. Sadece 1:9 ağırlık, ağırlık,  olivinodun karışımı ile üretilmiş PY1 deneme levhası kontrol örneğinden daha yüksek eğilme direnci 13.27 MPa ve elastiklik 2468.2 MPa göstermiştir PY0:12.75 MPa ve 2245.2 MPa.
