DEVELOPMENT OF EMULSION AND IMPREGNATION TECHNOLOGY FOR WOOD BIOPROTECTION

摘要

The timber used in impregnation and leachability experiments was vacuum dried pinewood (Pinus silvestris). Impregnating emulsion joins the benefits of both water solutions and oil. The new impregnation emulsion was tested against the emulsion prepared from widely used "Tanalith E" wood preservative. The obtained results demonstrated that a new penetration agent ensures effective protection against wood rotting fungi and discolouring fungi. Bio testing at Latvian State Institute of Wood Chemistry (EN113) revealed that a new penetration agent ensures effective protection against wood rotting fungi (mass loss less than 3%) and discolouring fungi (mould).
