Preservative properties of boron-treated paulownia wood
2024 - IRG/WP 24-20729
This research was performed to investigate the preservative retention properties of paulownia wood treated using boric acid/borax at mass ratio of 1:1.8. Different portion of paulownia wood (top, middle, bottom) were used as a sample throughout of this study. In the treatment process, the paulownia wood was dipped in the 1% boric acid/borax solution for 1, 24, 72, 120 and 240 hours to achieve requ...
