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.
