THE USE OF MAGNESIUM OXIDE NANOPARTICLES IN WOOD MODIFICATION FORMULATIONS

New formulations for processing pine wood based on waste vegetable oil using nanoscale magnesium oxide have been studied. As a filler in the composition of impregnating compositions, coniferous wood flour was used in an amount from 1 to 3%, as well as magnesium oxide nanopowder in a dosage from 0.01 to 0.1%. Processing pine wood with compositions based on vegetable oil with additives of magnesium oxide allows to improve the hydrophobic properties of the wood surface, reduce its swelling, moisture and water absorption.
