UDC 532.546:674.048

A calculational model for the process of deep impregnation 
of wood with solutions and water-polymer emulsions is developed that 
takes account of the motion of the fluid, the polymer particles, and 
the air in the porous structure. Calculated results for the kinetics 
of impregnation of wood under the action of a pressure gradient and 
the distribution of the fluid in the material volume are presented. 
A comparison with experimental data for dry and wet wood is performed.
