THE MATHEMATICAL MODEL OF ADHESION OF OIL COMPOSITIONS OVER WOOD SURFACE

L.A. Yaremchuk, B.P. Pobereyko

Abstract


A mathematical model for the study of the work of adhesion of oil compositions on the wood substrate is proposed. Time for spreading oil composition over the wood surface is theoretically determined. We identify boundary conditions of thermodynamic parameters that describe the relationship of wood (solid) with an oil composition (liquid) according to the Gibbs law, for construction of the mathematical model of the work of adhesion. The influence of the thermodynamic properties of wood and oil composition on the contact angle of the surface is defined. The dependence of the time for spreading of the oil composition over the wood surface is obtained.
