Özet:

 In this study, the effect of phenol formaldehyde resin ratio on some physical and mechanical properties of single-layer particle board was investigated. In particle board production, 40 fine - 60 coarse chipboard was used as wood raw material, and phenol-formaldehyde resin with 45 solids content was used as adhesive. During the preparation of particleboard test samples, the production parameters such as press pressure, temperature, time and chip amount were kept constant and the adhesive percentage was adjusted to 8, 10 and 12 according to the dry chip weight. Some physical properties of the produced particleboard, such as density, water absorption and swelling in thickness, and some mechanical properties, such as bending, modulus of bending and internal bonding strength internal adhesion, were determined in accordance with TSE standards. Particleboard produced with phenol formaldehyde were also compared and statistically evaluated in terms of the same properties with the board prepared using 10 urea formaldehyde resin. The best results in bending strength, internal adhesion resistance and thickness increase were obtained when 10 and 12 phenol formaldehyde was used. There was no statistical difference between the groups produced with 8 phenol formaldehyde and 10 urea formaldehyde resins and these groups showed a lower performance than other groups. Boards produced with 10-12 phenol formaldehyde resin took in 45 less water and swelled 35 less in 72 hours than boards produced with 10 urea formaldehyde resin. In the study, the surface chemistry of boards with different glue ratios was analyzed and compared with ATR-FTIR.

 Bu çalışmada, fenol formaldehit tutkal oranı farklılığının tek katlı yonga levhanın bazı fiziksel ve mekanik özellikleri üzerine etkisi araştırılmıştır. Yonga levha üretiminde, odun hammaddesi olarak 40 ince- 60 kaba yonga, tutkal olarak da 45 katı madde oranına sahip fenol-formaldehit reçinesi kullanılmıştır. Yonga levha deney örnekleri hazırlanma aşamasında, üretim parametreleri olan pres basıncı, sıcaklık, zaman, yonga miktarı sabit tutulup, tutkal yüzdesi kuru yonga ağırlığına göre 8, 10 ve 12 olacak şekilde ayarlanmıştır. Üretilen yonga levhaların yoğunluk, su alma ve kalınlığına şişme gibi bazı fiziksel özellikleri ile, eğilme, elastikiyet modülü ve yüzeye dik çekme direnci iç yapışma gibi bazı mekanik özellikleri ilgili standartlarına göre gerçekleştirilmiştir. Fenol formaldehit ile üretilen yonga levhalar ayrıca, 10 üre formaldehit tutkalı kullanılarak hazırlanan levha ile aynı özellikler bakımından kıyaslanmış ve istatistiki olarak değerlendirilmiştir. Eğilme direnci, iç yapışma direnci ve kalınlık artışında en iyi sonuçlar fenol formaldehit tutkalının 10 ve 12 oranında kullanılmasında elde edilmiş, 8lik fenol formaldehit ve 10lük üre formaldehit tutkalı ile üretilen gruplar arasında istatistiksel açıdan bir farklılık bulunmamış ve bu guruplar diğer gruplardan daha düşük bir performans sergilemiştir. 10-12 fenol formaldehit tutkalıyla üretilen levhalar, 10 üre formaldehit tutkallarıyla üretilen levhalara göre 72 saatte 45 kadar daha az su almış ve 35 oranında daha az şişmiştir. Çalışmada ayrıca, farklı tutkal oranlarına sahip levhaların yüzey kimyası ATR-FTIR ile analiz edilerek karşılaştırılmıştır.
