⚡ TL;DR(Too Long; Didn't Read)

It was found that the adhesion performance of unmodified PVAc and K.303 bonded samples decreases when temperature increases, moreover, this retuction is smaller in samples bonded with PVAc+UF and K.303+UF in comparison to unmodified glues and in samples of beech wood in comparison to pine wood.

Abstract

In this study, performances of woods bonded with polyvinylacetate (PVAc) and Klebit 303 (K.303) thermoplastics glues and PVAc+UF and K.303+UF thermoset glues that were modified with Urea-fomaldehyde were investiguted at various temperatures. In total, 320 experimental samples were investigated at various temperatures which were prepared from pine wood (Pinus sylvestris L.), beech wood (Fagus orientalis L.) and were bonded with PVAc, K.303, PVAc+UF, K.303+UF glues. After these experimental samples were held for two hours at 20 °C, 40 °C, 60 °C, 80 °C temperature, tensile test was applied according TS EN 205. It was found that the adhesion performance of unmodified PVAc and K.303 bonded samples decreases when temperature increases, moreover, this retuction is smaller in samples bonded with PVAc+UF and K.303+UF in comparison to unmodified glues and in samples of beech wood in comparison to pine wood.

Özet

Bu çalışmada, termoplastik sertleşen Polivinilasetat (PVAc), Klebit 303 (K.303) tutkalları ve bunların termoset sertleşen Üre – formaldehit (UF) tutkalı ile modifiye edilmiş çeşitleri olan PVAc + UF ve K.303 + UF tutkalları ile yapışmış ağacın farklı sıcaklık ortamlarındaki yapışma performansları araştırılmıştır. Bu maksatla, sarıçam (Pinus Sylvestris L.) ve Doğu kayını (Fagus Orientalis L.) odunlarından hazırlanan toplam 320 adet deney örneği PVAc, K.303, PVAc + UF ve K.303 + UF tutkalları ile yapıştırılmıştır. Örneklere 20 °C, 40 °C, 60 °C, 80 °C'lik sıcak ortamlarda bekletildikten sonra TS EN 205 esaslarına göre çekme deneyi uygulanmıştır. Sonuç olarak, modifikasyonsuz PVAc ve K.303 tutkallı örneklerde ortamın sıcaklığı arttıkça yapışma performansının azaldığı, bu azalmanın PVAc + UF ve K.303 + UF tutkallı örneklerde modifikasyonsuzlara ve kayında sarıçama göre daha düşük oranda olduğu belirlenmiştir.
