Effects of some manufacturing factors on the properties of particleboard manufactured from alder (Alnus glutinosa subsp.Barbata)

Bu çalışmada, Kızılağaç (Alnus glutinosa subsp. Barbata) odunu yongalevha üretiminde kullanılmıştır. Bu çalışmanın amacı; kurutulmuş yonga rutubeti, dış:orta tabaka yonga oranı ve odun tozunun yongalara katılmasının yonga levhanın kalınlığına şişme oranı, eğilme ve yapışma dirençleri ile elastiklik modülü üzerindeki etkilerinin belirlenmesidir. Odun tozunun yongalara % 10 oranında katılması yapışma direncini arttırırken, kalınlığına şişme oranı, eğilme direnci ve elastiklik modülünü azaltmıştır. % l rutubete kadar kurutulmuş yongalardan üretilen yongalevhaların eğilme ve yapışma dirençleri ile elastiklik modülleri % 4 rutubete kadar kurutulmuş yongalardan üretilen levhalara oranla daha düşük, kalınlığına şişme oranları ise daha yüksek çıkmıştır. Dış:orta tabaka oranının % 30:70'den % 45:55'e çıkarılması sonucu fiziksel ve mekanik özellikler iyileşmiştir. Test sonuçlarına göre Kızılağaç (Alnus glutinosa subsp. Barbatamdan üretilen yongalevhaların eğilme ve yapışma direnci ile elastiklik modülü değerleri standartlarda öngörülen değerlerden yüksek bulunmuştur. Bununla birlikte, kalınlığına şişme oranları standartlarda öngörülen değerlerden yüksek çıkmıştır. Bu nedenle Kızılağaç (Alnus glutinosa subsp. Barbata)'öan üretilen yonga levhaların fiziksel özelliklerini iyileştirici ek bir çalışmaya ihtiyaç duyulmaktadır.

Abstract: In this study, Alder (Alnus glutinosa subsp.Barbata) wood was used for particleboard manufacturing. The purpose of this study was to determine the effects of particle moisture content, shelling ratio and the addition of wood dust on the mechanical properties (static bending, modulus of elasticity and internal bond) and physical property (thickness swelling) of particleboard. The addition of 10% wood dust to particles decreased the thickness swelling, modulus of elasticity and bending strength, while increasing the internal bond. Particleboards manufactured from particles with 1% moisture content had lower internal bond, modulus of elasticity and bending strength and higher thickness swelling values than those produced from particles with 4% moisture content. Increasing face:core ratio from 30:70% to 45:55% improved the physical and mechanical properties of particleboards. Overall results showed that particleboards made from Alder exceed the EN standards for internal bond, modulus of elasticity and static bending. However, thickness swelling values were higher (poor) than requirements. For this reason, additional work needs to be done on improving the physical properties of particleboard produced from Alder.
