Ahşabın yerinde bakım işlemlerinde bor bileşikleri

Emprenye edilmiş büyük boyutlu ahşap malzemeler ve tel direkleri, kullanımda eskidikçe iç ve dış çürümeler geliştirebilir. Bu zararın durdurulması, özellikle iç çürüme durumunda bir zorluk teşkil edebilir. Bor, çeşitli uygulamalarda mantar saldırısının durdurulmasına yardımcı olmada önemli bir rol oynar. Bu makale, boratların dış çürümeyi sınırlamak için bulamaçlarda bir bileşen olarak değerlendirilmesini ve iç çürümeyi durdurmak için bor çözeltilerinin veya çubukların kullanımını tartışmaktadır. Uzun süreli arazi denemeleri, bor difüzyonunun başlangıçta yavaş olduğunu, ancak uygulamadan yaklaşık 30 yıl sonra Douglas göknarı tel direklerinde borun bulunduğunu göstermektedir. Sonuçlar, kullanımdaki ahşap malzemede mantar saldırısını sınırlamak için yerinde bakım işlemlerinde borun değerini göstermektedir.

Borates in remedial treatments for timber in service

Large preservative-treated timbers and poles can develop internal and external decay as they age in service. Arresting this damage can pose a challenge, especially internal decay. Boron plays an important role in helping arrest fungal attack in a variety of applications. This paper discusses the use of borates as a component in pastes for limiting external decay and the use of boron solutions or rods for arresting internal decay. Long-term field trials show that boron movement is initially slow, but boron was found in Douglas-fir poles almost 30 years after application. The results illustrate the value of boron as a remedial treatment for limiting fungal attack in timber in service.
Keywords:
