“…Table 3 gives the comparison between the mean values of free surface energy y s and its disperse, s well s polar share y s d and y s p , respectively, determined by means of the values of the contact angle Θ 0 and 0 W . The free surface energy was determined according to Neumann et aL (1974), the disperse and polar share according to Kloubek (1974). Values of free surface energy, determined by means of the contact angle 0 0 at time zero, are comparable with the results from literature ( Table 4).…”

The analysis of water-wetting of wood was performed. Basic characteristics for wetting process were defined and determined experimentally -the contact angle at the beginning of wetting 0 and the equilibrium contact angle 0 U . Based on these characteristics, the contact angle, signed äs 0 W , corresponding to ideal smooth wood surface was determined. The results were used for the computation of free wood -surface energy and compared with the data from literature.

“…The free surface energy of coating materials g L was determined using the method of capillary elevation (Horák 1958 Brought to you by | New York University Bobst Library Technical Services Authenticated Download Date | 6/11/15 9:27 PM g d L and polar g p L share were determined according to Kloubek (1974) by solving the following equations (12) (13) based on the contact angle θ measured on the phase boundary with solid standard. The contact angle was determined from the shape of a drop on a solid standard according to the equation…”

“…As a solid standard, paraffin was used with its surface energy (g S = 25.06 mJm −2 ) determined according to Neuman et al (1974) with the disperse and polar share (g S d = 23.04 mJm −2 , γ S p = 2.02 mJm −2 ) according to Kloubek (1974). The measurements of free surface energy of the coatings were performed on statistical sets with n = 20 measurements, at t = 20°C and relative air humidity f = 65 %.…”

This paper deals with the evaluation of wood − wetting process with coating materials on the basis of interactions of surface forces on phase boundary. The obtained results are compared with the actual state in the system wood − coating material. Primary ability of coating materials − spontaneous spreading over the wood surface has been proved. There is also the secondary influence of rheological properties of coating materials causing deformations of the phase boundary, non-perfect wetting of the wood surface and apparent lowering of adhesion work. The influence of rheological properties has been expressed by using the coefficient F the meaning of which follows from the comparison between results of adhesion work computed according to modified Young-Dupré equation and of adhesion work determined on the basis of the interactions of surface forces on the phase boundary between wood and liquid coating materials. A direct dependence between the values of the coefficient F and coating materials viscosity has been proved.
