Description
Summary:	A mathematical model and results of the calculations of the kinetics of impregnation of porous materials by a fluid, whose viscosity essentially depends on temperature, are given. Modeling of the technological process of protective treatment of wooden articles is carried out using, as an example, the impregnation of wood under pressure by a water-oil antiseptic emulsion heated to 40°C. The efficiency of different methods of deep impregnation is analyzed in the context of both the absorption of a protective substance and the uniformity of its distribution in wood.[PUBLICATION ABSTRACT]
