ODUN ÖZELLİKLERİ VE YÜZEY İŞLEMLERİNE ETKİLERİ

Ağaç malzeme odun; mobilya, doğrama ve ahşap yapıların ana hammaddesini oluşturmaktadır. Doğal bir malzeme olarak odun; yetişme yeri koşulları, gövde yapısı, kesme ve diğer üretim yöntemlerine göre türler arasında olduğu gibi aynı tür içerisinde de farklı özellikler göstermektedir. Odun özellikleri, doğal ve üretim karakteristikleri olarak iki kısımda incelenmekte ve bunlar yüzey işlem performansını etkilemektedir. Bunlardan; yıllık halka yapısı, özgül ağırlık, budaklar, rutubet miktarı, ekstraktifler ve genç odun doğal; lif yönü, tekstür ve kuruma ise üretim karakteristiklerini içermektedir. Bu çalışmada; odunun doğal ve üretime bağlı özelliklerinin malzemenin performansı üzerine etkisi incelenmiştir.

WOOD PROPERTIES AND EFFECT OF WOOD PROPERTIES ON THE WOOD FINISHING

Wood is basic raw material for furniture and joinery industries with wood structures. Wood is a biological material that has widely different properties depending on species, geographic area where the tree grew, the growth condition, size of the tree at harvest, sawing, and other manufacturing processes. Wood properties have been characterized  within two groups as natural and manufacturing factors that effects finishing performance. Grow rate, density, knots, moisture content, extractives and juvenile wood are natural characteristics. Grain orientation, texture, drying and performance expectations are manufacturing characteristics. In this review,  the effects of natural and manufacturing characteristics are discussed on the  surface finishing performance of wood.
