Effects of treatment materials on the physical properties of Eucalyptus (Eucalyptus camaldulensis Dehn.) wood

Emprenye maddelerinin okaliptüs (Eucalyptus camaldulensis Dehn.) odununun fiziksel özelliklerine etkileri

Abstract

This study was designed to determine effects on retention and shrink levels of Eucalyptus (Eucalyptus camaldulensis Dehn.) which treated with some commercial preservative types, borates, polyethylene glycol, and water repellents. In this study, four type impregnation chemicals were chosen: 1. Commercial preservative types, [Ammonium sulphate, Vacsol-WR WR and Immersol-WR (WR)], 2. Borates chemicals, [Boric acid, Borax, Boric acid+ Borax] 3. Polyethylene glycol such as Polyethylene glycol (PEG-400) 4. Water repellents [Styrene, Methylmetacrylate.]. As a result, retention % and shrink levels of Eucalyptus wood was lower treated with commercial preservative types and borates preservatives compare to other treatment chemicals. However, retention % levels of Eucalyptus wood treated with WR chemicals were highly significant levels. According to their leachability period although PEG 400 showed antishrink effectiveness other treatments didnt showed antishrink efficiency.

Özet

Bu çalışma; bazı ticari emprenye maddeleri ve borlu-polietilen glikol'le işleme tabi tutulan okaliptüs odununda, emprenye maddelerinin retensiyon ve daralma miktarina etkilerinin belirlenmesi amaçlarına yönelik olarak hazırlanmıştır. Araştırmada dört tip emprenye maddesi grubu seçilmiştir: l.Ticari emprenye maddeleri; [Amonyum sülfat, Vacsol-WR (WR), lmmersol-WR WR ve Tanalith-CBC] ; 2. Borlu bileşikler; [Borik asit, Boraks], 3. Polietilen glikol (400); 4. su iticiler; [Stiren, Metilmetakrilat] kullanılmıştır. Çalışmada elde edilen sonuçlara göre; ticari ve borlu maddelerle emprenye edilen okaliptüs odununda tam kuru oduna oranla % retensiyon değerleri düşük düzeyde gerçekleşirken; su itici maddelerle muamele edilen okaliptüs odununda istatistiksel anlamda önemli (P
