The Decay Resistance Properties of P. Ussuriensis Kom Lumber Impregnated with Preservative by Roller-compression
1. Introduction It is a new technique used to impregnate preservative into wood lumbers go forward between two rollers in the preservative liquid, the Dimension of lumbers reduce in the direction of compression because of compression, with the rotation of the rollers, the water and air in the wood gap was pushed out of wood, when the compressed part leave the rollers, wood may restore the original shape and size, in the wood vacuum come into being, the preservative was absorbed into the wood on account of the vacuum, the impregnated wood processing was completed. This study research that the water-saturated P. ussuriensis Kom timber was processed with the impregnation-roller-compression method through two water-borne preservative (DDAC and boride), different compression ratio -impregnation depth -retention and mass loss ratio was measured, the wood decay resistance levels was ascertained.
