Abstract: The invention relates to a device (1) for intermixing a compound such as a dispersion, comprising a container (2), particularly a large-volume container (2), and a mixing unit (3) arranged on said container (2). According to the invention, the mixing unit (3) comprises at least one piston (4) that is mounted in said container (2), can be linearly displaced, and comprises at least one mixing element (5) which extends two-dimensionally around said piston (4) for the purpose of intermixing the compound. The invention also relates to a use for a claimed device (1). The invention also relates to a method for intermixing a compound such as a dispersion in a container (2), particularly a large-volume container (2), with a mixing unit (3) arranged on said container (2), by means of the movement of said unit.

Abstract: The object of the invention is a method for improving the impregnability of refractory wood species by pretreatment with fungi of the genera Trichoderma o Gliocladium or with weakly wood-degraging fungi. The pretreatment comprises a thermal treatment of the wood, the addition of a nutrient medium as well as an incubation phase to promote fungal growth. The incubation phase is stopped when the desired depth of penetration of the fungus is reached. The wood is subsequently impregnated with a wood impregnating agent. The typical result of the fungal pretreatment is an incarease in the depth of penetration of the impregnating agent to a depth of penetration of 5 mm to 30 mm required depending on the intended use.
