The optimum level of nano-wollastonite consumption as fire-retardant in poplar wood (Populus nigra)
Fire-retarding properties of wollastonite nanofibers in poplar wood (Populus nigra) were studied here. Some physical properties such as water absorption, volumetric swelling and anti-swelling efficiency (ASE) were also measured. Specimens were prepared according to the ISO 11925 specifications for the fire-retarding properties and according to the ASTM D4446 -2002 specifications for th...

متن کاملKinetic Models for Thermal Degradation of Strength of Fire-retardant-treated Wood
Several types of kinetics-based thermal degradation models were evaluated to predict strength loss of fire-retardant-treated wood as a function of cumulative thermal exposure. The data were taken from previous tests and reports on small, clear specimens of southern pine treated with six different fire-retardant chemicals and subjected to various durations of a steady-state exposure at different...
متن کاملEffects of Fire Retardant on Water Quality1
Ammonium-based fire retardants are important in managing wildfires, but their use can adversely affect water quality. Their entry, fate, and impact were studied in five forest streams. Initial retardant concentrations in water approached levels which could damage fish, but no distressed fish were found. Concentrations decreased sharply with time after application and distance downstream, and th...
