Abstract

Impregnation of wood comprises: immersion of the wood in a preheated dispersion containing impregnating oil and water soluble polymers; extracting water from the wood; creating a shear force in the dispersion to split the polymers and create a greater surface area for drawing in additional water; and then pressurizing the emulsion into the wood in one or more cycles. A dispersion is created in a tank (1) by combining impregnating oil and water soluble polymers. The dispersion is preheated to 100 [deg]C and pumped into an impregnation tank (13) containing wood to be treated. The dispersion temperature is raised to 100-130 [deg]C while continuously circulating and water extracted from the wood is partially combined with the polymers. A shear force is then created in the dispersion to split the polymers and create a greater surface area for drawing in additional water. The emulsion is then pressurized into the wood in one or more cycles. An independent claim is also included for the process plant comprising a dispersion forming tank (1) and an impregnation tank with a unit (26) for producing a shear force in the dispersion.
