Aim of study: The adsorption properties of the samples of full-dry Eastern Spruce (ES) [Picea orientalis (L). Link.] with 12.5 mm, 25 mm, 37.5 mm and 50 mm thick is to determine under the climate conditions with 42%, 65% and % 78 of relative humidity and at a constant temperature of 20 °C.
Material and method: The wood samples used in this study were the Eastern Spruce woods which were obtained from Forestry Process Management in the city of Trabzon/Turkey. With regard to mathematical modeling used to determine the wood moisture content (MC), the equation constants in case of adsorption was determined. Experiments were conducted at three different equilibrium moisture content (EMC); 8%, 12% and 16%.
Main results: Cross section had no crucial effect on the rate of accessibility to the final MC. However, EMC and thickness have been effective.
Research highlights: In practice, since dried wood is kept at outside weather conditions for a certain time before operation, an increase can be observed in the wood MC. It is practically important that under the influence of climate conditions until its utilization, the tendency of water adsorption of wood is determined as a function of time.

Doğu Ladini Odununun [Picea orientalis (L.) Link.] Rutubet Adsorpsiyonu Üzerine Bir Araştırma

Öz

Çalışmanın amacı: Tam kuru Doğu ladini [Picea orientalis (L). Link.] örneklerinin 12.5 mm, 25 mm, 37.5 mm ve 50 mm kalınlıkta, 20 ° C sabit bir sıcaklıkta ve % 42 ,% 65 ve %78 farklı bağıl nem koşullarında adsorpsiyon özelliklerini belirlemektir.
Materyal ve yöntem: Bu çalışmada Maçka Orman İşletme Müdürlüğü’nden alınan Doğu Ladini örnekleri kullanılmıştır. Odun rutubet içeriğini belirlemek için kullanılan matematik modelleme ile adsorpsiyon durumunda denklem sabitleri belirlenmiştir. Deneyler, % 8, % 12 ve % 16 olmak üzere üç lif doygunluk noktası için gerçekleştirilmiştir.
Sonuçlar: Kesitin, denge rutubetine erişilebilirlik oranı üzerinde önemli bir etkisinin olmadığı, bununla birlikte denge rutubet miktarı ve kalınlığın etkili olduğu belirlenmiştir.
Araştırma vurguları: Kurutulmuş odunun, kullanım öncesinde belirli bir süre dış hava şartlarında tutulduğunda rutubet içeriğinde bir artış gözlemlenebilir. Kullanıma kadar iklim koşullarının etkisi altında, odunun rutubet alma eğiliminin zamanın bir fonksiyonu olarak belirlenmesi pratik olarak önemlidir.
