Abstract

EN The coverage of abrasive (fused alumina) by resol, used in manufacturing of grinding tools, was estimated by means of inverse gas chromatography (IGC). γ ^D_S and χ ^∞₁₂ parameters were used to describe the wettability of abrasive by resol. γ ^D_S shows activity of the surface of fused alumina and it was found that it is correlated with the wettability of fused alumina by resol. By using χ ^∞₁₂ it was possible to calculate the degree of the coverage (DC parameter) of abrasive by resol. This method was used as an alternative for the Washburn sorption method. IGC was found to be more accurate and informative method. The results show that IGC can be applied to quantitatively determine the degree of coverage the abrasive material, fused alumina, by resol.
