Özet:

 In this study, the adhesion performance of wood glues was evaluated depending on temperature. Polyvinyl acetate PVA and poly urethane PU glue were used to adhere to the Back pine Pinus nigra wood samples. The adhesion performance of the samples was determined under three different temperature effects: below room temperature 4  C, at room temperature 22  C, and above room temperature 55  C. After sticking, the samples were clamped with a hand vise and left to cure at three different temperatures. Lap sheer strength LSS, modulus of rupture MOR and modulus of elasticity MOE analyses were performed for the mechanical characterization of the samples. According to the obtained results, the LSS Load at Specified Strain strength increased below and above room temperature. In contrast, the MOR Modulus of Rupture and MOE Modulus of Elasticity strengths decreased below and above room temperature. Thus, it was concluded that in addition to the adhesive strength varying with temperature, the direction of the force application also influences the strength. Especially in small workshops, the ambient temperature is greatly influenced by summer and winter conditions. This, in turn, affects the adhesive strength and the quality of the work for wood bonding. Supporting small and medium-sized enterprises SMEs with similar studies is essential to improve the quality of their work.

 Bu çalışmada, ahşap tutkallarının yapışma performansı, sıcaklığa bağlı olarak değerlendirilmiştir. Karaçam Pinus nigra odun örneklerinin yapıştırılmasında, polivinil asetat PVA ve poliüretan PU yapıştırıcıları kullanılmıştır. Numunelerin yapışma performansı, oda sıcaklığının altı 4 C, oda sıcaklığı 22 C ve oda sıcaklığının üstü 55 C olmak üzere üç farklı sıcaklık etkisi altında belirlenmiştir. Yapıştırıldıktan sonra numuneler el mengenesi ile sıkıştırılarak üç farklı sıcaklıkta kürlenmeye bırakılmıştır. Numunelerin mekanik karakterizasyonu için makaslamada çekme direnci LSS-Load at Specified Strain, eğilme direnci MOR- Modulus of Rupture ve eğilmede elastikiyet modülü MOE- Modulus of Elasticity analizleri yapılmıştır. Elde edilen sonuçlara göre, LSS direnci oda sıcaklığının altında ve üzerinde artış göstermiştir. Buna karşın, MOR ve MOE güçleri, oda sıcaklığının altında ve üzerinde azalmıştır. Böylece, sıcaklığa bağlı olarak değişen yapışma mukavemetinin yanı sıra kuvvet uygulama yönünün de mukavemeti etkilediği sonucuna varılmıştır. Özellikle küçük atölyelerde ortam sıcaklığı yaz ve kış koşullarından büyük ölçüde etkilenir. Bu da ahşabın yapıştırılması için yapılan işin yapışma gücünü ve kalitesini etkiler. Küçük ve orta ölçekli işletmelerin KOBİler benzer çalışmalarla desteklenmesi, yaptıkları işin kalitesinin artırılması açısından önemlidir.
