Bu çalışma, kolofan reçinesi (C₁₉H₂₉COOH)
katkılı borlu bileşiklerle (Boraks (Na₂B₄O₇10H₂O)
+ Borik asit (H₃BO₃) - ağırlıkça % 50:50) emprenye
edilmiş Sarıçam (Pinus Sylvestris Lipsky)
odununun yanma özelliklerinin belirlenmesi amacıyla yapılmıştır. Bu amaçla,
sarıçam deney örnekleri kolofan reçinesi katkılı borlu bileşiklerle ASTM D 1413
standardı esaslarına göre daldırma metodu ile emprenye edilmiştir. Emprenye
edilen deney örneklerinin yanma özellikleri ASTM E 160 standardı esaslarına
göre belirlenmiştir. Araştırmanın bir parçası olarak, özellikle farklı
konsantrasyonlarda hazırlanan borlu bileşikler ile emprenye edilmiş ahşap
malzemenin yanma direncini araştırmak için 6 farklı kombinasyon kullanılmıştır.
Kolofan reçinesi ilavesiyle borlu bileşiklerin tutunma performansının ve
yıkanma direncinin arttığı tespit edilmiştir. Kolofan katkılı borlu
bileşiklerle emprenye edilen deney örneklerinde, kontrol örneklerine göre alev
kaynaklı yanma (Fsc) sıcaklığı, yanma süresi ve ağırlık kaybı oranlarında düşüş
görülmüştür. Kolofan reçinesi, ahşabın cinsine ve kullanım alanına bağlı olarak
borlu bileşikler içinde katkı maddesi olarak tercih edilebilir.

Combustion properties of Scots pine (Pinus sylvestris Lipsky) wood impregnated with boron compound doped colophony

Öz

The aim of
this study was to investigate the combustion properties of Scots pine (Pinus sylvestris Lipsky) wood
impregnated with boron compound (borax (Na₂B₄O₇10H₂O),
boric acid (H₃BO₃) w/w
50:50%) doped colophony (C₁₉H₂₉COOH). For this aim, Scots
pine wood samples were impregnated with boron compound doped colophony by the
method of medium-term dipping according to ASTM D 1413 and producers’
definition. Combustion properties of samples after impregnated process were
determined according to ASTM E 160. As a part of the research, 6 different
combination and contents of impregnation materials have been used in order to
especially investigate resistance against combustion of wood material treated
with boron compounds in different concentrations. Consequently, retention
performance and leaching resistance of boron compounds can be increased through
colophony addition. Impregnation materials with colophony decreased the flame
sourced combustion (Fsc) temperatures depending on kind of impregnation
material, combustion period and weight loss ratio of the test samples decreased
in comparison to the control samples. Colophony can be preferred in
impregnation with boron compounds depending on kind of wood and using area.
