Abstract
This study was designed to determine some physical properties such as surface roughness and oven dry density, and some mechanical properties such as modulus of elasticity (MOE) of borate-treated wood specimens. Wood specimens were prepared from Oriental beech (Fagus orientalis L.). Ammonium pentaborate octahydrate (APBO), ammonium tetrafl uoroborate (ATFB), and sodium tetrafl uoroborate (STFB) were used as borates. Before tests, wood specimens were impregnated with 0.25, 0.50, 1.50, and 3.00 percent aqueous solutions of borates. The results showed that borate treatment caused increases in oven dry density and surface roughness, while it decreased MOE values of Oriental beech.
Highlights
The results showed that borate treatment caused increases in oven dry density and surface roughness, while it decreased modulus of elasticity (MOE) values of Oriental beech
Our results showed that increased solution concentration of borates did not adversely influence surface roughness of Oriental beech
3.00 % ammonium pentaborate octahydrate (APBO) caused the lowest increase of surface roughness, while the treatment with 3.00 % ammonium tetrafluoroborate (ATFB) caused the highest increase of surface roughness of Oriental beech
Summary
Borates have several advantages as wood preservative in addition to imparting flame retardancy, providing sufficient protection against wood destroying organisms and low volatility. Baysal and Yalinkilic (2005) studied decay resistance of wood against brown and white rot fungi, impregnated with boron containing compound named PHN. Yuksel et al (2014) investigated combustion properties of Oriental beech impregnated with boric acid, borax, and sodium perborate They found that mass loss and temperature values of borate-treated wood specimens were lower than untreated wood specimens at all combustion stages. Jin et al (2014) studied fire resistance of disodium octoborate tetrahydrate, and boric acid impregnated Southern pine wood by TG analysis They found that while the mass loss rate decreased, the char yield increased impregnated with borates after TG analysis.
