Abstract

Teknolojinin
gelişimiyle birlikte metal, plastik, lif-yonga levha gibi ahşap levha esaslı ve
ahşap dışı ürünlerin çeşitliliğinin artmasıyla, sayısız olumlu özelliği bulunan
masif ahşabın popülerliği azalmıştır. Ancak bu malzemeye olan ilgi, ekolojik
farkındalık ile son yıllarda farklı tasarımlarla üretilmeye başlanan doğal
masif ahşap ürünlerle artmaya başlamıştır. Doğal olarak mobilya endüstrisinin
bu artışa katkısı yadsınamaz.Bu çalışma kapsamında masif ahşabın artan değeri, önceleri kusurlu veya
atık olarak nitelendirilen doğal masif ahşap ürünlerin daha çok son kullanıcıya
hitap eden mobilya endüstrisinin etkisi ile açıklanmaya çalışılacaktır. Bununla
birlikte artan ekolojik yaşam bilinci, son kullanıcının masif ahşap gibi doğal
malzemelere yönelmesine sebep olmuştur. Son yıllarda geliştirilen ve masif
ahşabın birçok özelliğini katkı maddesi kullanılmadan arttıran yüksek
frekans-vakum kombinasyonlu kurutma ve ısıl işlem gibi koruma teknikleri de
masif ahşabın kullanım alanlarını arttırmaya yönelik olumlu katkı
yapmıştır.

REINCREASING VALUE OF SOLID WOOD

Abstract

Popularity of solid wood which has many positive features, decreased due to increasing popularity of both wood-based products and non-wood products such as metal, plastic, fiber-particle board etc. with technological improvement. However interest to solid wood material increased with ecological awareness and featured natural solid wood product designs in recent years. Naturally share of furniture industry can not be ruled out to effect of the increment.

In this study, increasing value of solid wood will be tried to explain with natural solid wood products which were previously evaluated defective or waste and effect of furniture industry appealing more to end-user. However increasing natural-life awareness caused to orient end-users towards to natural products like solid wood. In recent years the developed technologies such as high frequency-vacuum drying and thermal-treatment technologies contributed positively by reason of adding value to solid wood with increasing features without using addictives, as a result of that these techniques expanded usage area of solid wood.
