Effect of fixation time on leaching of copper-ethanolamine based wood preservatives

  • 77 Accesses

  • 7 Citations

Zusammenfassung

Fixation in copper-ethanolamine treated Norway spruce wood is finished in the first or in the second week after impregnation depending on the concentration of wood preservatives used. However, copper losses increased after four weeks of fixation again, presumably due to lignin depolymerisation caused by ethanolamine.
