Prediction of Retention Level and Mechanical Strength of Plywood Treated With Fire Retardant Chemicals by Artificial Neural Networks
Öz
The treatment with fire retardant chemicals is the most effective process to protect wood and wood based products from fire is. Therefore, use of fire retardant chemicals has been increased. However, the fire retardant chemicals have an effect on other physical, mechanical and some technological properties of the materials treated with them. In this study, firstly, the retention level prediction model was developed with the artificial neural network (ANN) to examine the effects of wood species and concentration aqueous solution on the retention levels of veneers. Then, the effects of wood species, concentration aqueous solution and retention level on the mechanical properties of plywood were investigated with the mechanical strength prediction model developed with ANN. The prediction models with the best performance were determined by statistical and graphical comparisons. It has been observed that ANN models yielded very satisfactory results with acceptable deviations. As a result, the findings of this study could be employed effectively into the forest products industry to reduce time, energy and cost for empirical investigations.

Yangın Geciktirici Kimyasallarla Emprenye Edilmiş Kontrplakların Retensiyon Miktarları ve Mekanik Dirençlerinin Yapay Sinir Ağları ile Tahmin Edilmesi
Öz
Yangın geciktirici kimyasallar ile emprenye işlemi, ahşap ve ahşap esaslı ürünlerin yangından korunmasında çok etkili bir işlemdir. Bu yüzden, yangın geciktirici kimyasalların kullanımı tüm dünyada artmaktadır. Ancak, yangın geciktirici kimyasallar, uygulanmış oldukları malzemelerin fiziksel, mekanik ve diğer bazı teknolojik özellikleri üzerinde bir etkiye neden olmaktadır. Bu çalışmada ilk olarak, ağaç türlerinin ve konsantrasyon miktarlarının kaplamaların retensiyon miktarları üzerindeki etkilerini incelemek için yapay sinir ağı (YSA) ile retensiyon miktarı tahmin modeli geliştirilmiştir. Daha sonra YSA ile geliştirilen mekanik direnç tahmin modeli ile ağaç türleri, konsantrasyon miktarları ve retesiyon miktarlarının kontrplağın mekanik özelliklerine etkileri araştırılmıştır. En iyi performansa sahip tahmin modelleri, istatistiksel ve grafiksel karşılaştırmalarla belirlenmiştir. YSA modellerinin kabul edilebilir sapmalarla oldukça tatmin edici sonuçlar verdiği görülmüştür. Sonuç olarak, bu çalışmanın bulguları, deneysel araştırmalar için zaman, enerji ve maliyeti azaltmak için orman ürünleri endüstrisinde etkin bir şekilde kullanılabilecektir.
