Abstract

In this study, the effects of the fire retardant finishing processes of walnut (Juglans regia L.) impregnated with different chemicals on the combustion resistance were examined. For this purpose, boric acid, borax, sodium silicate, diammonium phosphate, ammonium sulfate and zinc chloride were used as impregnation material. Fire retardant paint and nano-enabled fire-retardant varnish were used as the finishing material. Combustion tests were carried out with computer-controlled wood material combustion apparatus developed according to ASTM-E 69 standard. Flue gas analysis was performed with the Testo 350M / Xl gas analyzer. In this way, carbon monoxide (CO), nitrogen oxide (NO), oxygen (O2) and flue temperature values were obtained. Consequently, it has been observed that finishing of Walnut wood with fire-retardant paint is more effective than impregnation of it with all the impregnation materials used in reducing weight loss. However, it has been observed that the application of nano-type fire retardant varnish results in less weight loss than impregnation with borax, boric acid, sodium silicate and diammonium phosphate.

Özet

Bu çalışmada, farklı kimyasallarla emprenye edilen ceviz (Juglans regia L.) ağaç malzemede yangın geciktirici üst yüzey işlemlerinin yanma direncine etkileri incelenmiştir. Bu amaçla emprenye maddesi olarak borik asit, boraks, sodyum silikat, diamonyum fosfat, amonyum sülfat ve çinko klorür kullanılmıştır. Üst yüzey malzemesi olarak ise yangın geciktirici boya ve nano özellikli yangın geciktirici vernik kullanılmıştır. Yanma deneyleri, ASTM-E 69 standartlarına göre geliştirilen bilgisayar kontrollü ağaç malzeme yanma düzeneğinde gerçekleştirilmiştir. Baca gazı analizi Testo 350M/Xl gaz analiz cihazıyla gerçekleştirilmiştir. Bu sayede karbon monoksit (CO), azot oksit (NO), oksijen (O2) ve baca sıcaklığı değerleri elde edilmiştir. Sonuç olarak, ceviz ağaç malzemeye yangın geciktirici boya ile üst yüzey işlemi uygulamanın, kullanılan tüm emprenye maddelerinden ağırlık kaybını azaltmada daha etkili olduğu gözlemlenmiştir. Bununla birlikte, nano özellikli yangın geciktirici vernik ile üst yüzey işlemi uygulamanın boraks, borik asit, sodyum silikat ve diamonyum fosfat ile emprenye etmekten daha az ağırlık kaybına yol açtığı gözlemlenmiştir.
