Abstract
The aim of this paper is to determine the effect of dealkalization of the glass surface on the quality of adhesion of bonded parts to the glass. Most of the available studies on glass dealkalization tend to focus only on the properties of the glass itself and the processes taking place in the surface layers of the glass. However, in practice focused on adhesion, the cleanliness of the glass surface is an important factor, which is influenced, among other things, by dealkalization. In this work, the influence of the use of gaseous SO2 in the furnace on the composition of the glass surface and on the resulting adhesion is assessed. Regarding the deterioration of the adhesion quality between the glass treated with SO2 gas and the adhesion promoter, the cleaning efficiency of the glass surface was further tested, according to the results of the cross-cut test.
