Dolomit ve Olivin ile Kızılçam Odun Yonga Karışımından Üretilen Deneme Levhalarının Özellikleri. Bölüm 1. Fiziksel Özellikler
Abstract
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 (ağırlık/ağırlık) dolomit/odun ve olivin/odun 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 dolomit/odun yongası karışımından (ağırlık/ağırlık, %) 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 olivin/odun 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, %) olivin/odun 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).

Properties of Experiemntal Panels Made from Mixture of Dolomite and Olivine with Calabrian pine Wood Particles. Part 1. Physical properties
Abstract
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 (w/w) dolomite/wood and olivine/wood 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 dolomite/wood 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 olivine/wood 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,%) olivine/wood and proportions, show higher bending strength (13.27 MPa) and elasticity (2468.2 MPa than control (PY0:12.75 MPa vs 2245.2 MPa).
