Abstract

This study investigated the preventive effectiveness of geothermal resource waters on the volumetric shrinkage and swelling properties (working property) of wooden. For this purpose, Turkish red pine (Pinus brutia Ten.) wood samples were treated by immersion method with nine different geothermal source water from Turkey's three different geothermal fields (Afyonkarahisar, Denizli, Kütahya). A higher performance against shrinkage and swelling was observed in wood samples treated with Denizli’s geothermal resource waters. Also, all treated wood samples had lower swelling and shrinkage values compared to untreated ones. These reductions in swelling and shrinkage values show that geothermal resource waters could be effective in reducing the volumetric working property of wooden.

Jeotermal kaynak sularının ahşabın hacimsel daralma ve genişleme özelliklerine karşı önleyici etkinliği

Abstract

Bu çalışmada, jeotermal kaynak sularının, ahşabın hacimsel daralma ve genişleme özelliklerine (çalışma özelliği) karşı önleyici etkinliği araştırılmıştır. Bu amaçla, kızılçam (Pinus brutia Ten.) odunu örnekleri Türkiye'nin üç farklı jeotermal enerji sahasından (Afyonkarahisar, Denizli ve Kütahya) dokuz farklı jeotermal kaynak suyu ile batırma yöntemine göre muamele edilmiştir. Denizli’nin jeotermal kaynak suları ile muamele edilen odun örneklerinde genişleme ve daralmaya karşı daha yüksek bir performans gözlenmiştir. Ayrıca, işlem görmüş tüm ahşap numuneler, işlem görmeyenlere kıyasla daha düşük genişleme ve daralma değerlerine sahip olmuştur. Genişleme ve daralma değerlerindeki bu azalmalar, jeotermal kaynak sularının ahşabın hacimsel çalışma özelliğini azaltmada etkili olabileceklerini göstermektedir.
