Decay Resistance of Carbonized Wood Surfaces

Key Findings & Data:In this context either single or five geometrical surfaces of Scots pine and beech wood specimens were carbonized and exposed to Coniophora puteana (brown rot) and Pleurotus ostreatus (white rot) decay fungi for 12 weeks.

💡

Conclusion & Impact:According to the results single or five surface carbonized Scots pine specimen showed reduced weight loses when compared to un-carbonized controls.

Abstract

In this study, decay resistance of carbonized wood surfaces by combustion method was examined. In this context either single or five geometrical surfaces of Scots pine and beech wood specimens were carbonized and exposed to Coniophora puteana (brown rot) and Pleurotus ostreatus (white rot) decay fungi for 12 weeks. According to the results single or five surface carbonized Scots pine specimen showed reduced weight loses when compared to un-carbonized controls. Beech wood specimens, on the other hand, resulted significantly low weight losses only for five surface carbonized specimens. A statically significant difference was found between the control samples of both wood species. Since surface carbonization did not introduce any differences among the treatment types of white rot fungi for both wood species, this method could be useful against brown rot fungi (C. puteana) risk.

Özet

Bu çalışmada pürmüz ile yakma metodu uygulanarak yüzeyleri karbonlaştırılan sarıçam ve kayın odun örneklerinin çürüklük mantarlarına karşı dayanımı araştırılmıştır. Bu kapsamda tek ve beş yüzeyi karbonlaştırılan örnekler ağaç malzemede esmer ve beyaz çürüklük meydana getiren Coniophora puteana ve Pleurotus ostreatus mantarlarına karşı 12 haftalık süreyle maruz bırakılmıştır. Çalışma sonucunda esmer çürüklük mantarına maruz bırakılan sarıçam odun örneklerinde tek ve beş yüzeyi karbonlaştırılan örneklerde, kayın odununda ise beş yüzeyi karbonlaştırılan örneklerin ağırlık kayıplarında azalma olmuştur. Her iki ağaç türünün kontrol örnekleri ile aralarında istatistiki olarak da anlamlı fark bulunmuştur. Beyaz çürüklük mantarına maruz bırakılan örneklerin her iki ağaç türü içinde kontrol örnekleri arasında ağırlık kayıpları bakımından istatistiki olarak fark bulunmamıştır. Bu sonuçlar karbonlaştırılan odun örneklerinin esmer çürüklüğün (C. puteana) risk olduğu yerlerde kullanılabileceğini ortaya koymuştur.
