Kolofan reçinesi katkılı borlu bileşiklerle emprenye edilen Sarıçam (Pinus Sylvestris Lipsky) odununun yanma özellikleri

Öz

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.
