Abstract:

This paper gives an overview about an effective protection technology of pinewood. The new impregnation emulsion based on rapeseed-oil and boron compounds was developed and tested. To compare the efficiency of new impregnate widely used ‘Tanalith E’ wood preservative was used. The obtained results demonstrate that the new impregnation agent ensures effective protection against wood rotting fungi and discolouring fungi. Bio testing according to the EN113 at Latvian State Institute of Wood Chemistry revealed that the new preservative ensures effective protection against wood rotting fungi (mass loss less than 3%) and discolouring fungi (mould).
