| Description | Laminated glass is produced in civil engineering industries by layering two or more glass sheets between which a safety foil (interlayer) is placed. The role of this safety layer is to increase residual load-bearing capacity after breakage and prevents the release of broken glasses due to their high adhesion to the safety film. Compared to “standard” PVB interlayers, a new generation of SentryGlas® Ionoplast interlayer is tougher, 100 times stiffer, and performs better over a more comprehensive temperature range. The Ionoplast interlayer does not depend on the type of glass support and has more significant resistance to aging and clarity. Low adhesion of Ionoplast to glass is a technical problem that limits its use, e.g., in producing thin LSGs and photovoltaic panels. At CEPLANT, by applying atmospheric-pressure plasma to the air side of the glass as well as the Ionoplast prior laminating process, there was a significant improvement in the adhesion of the Ionoplast interlayer. During a research project ongoing with the OGB s.r.o. company, we tried to determine the optimal conditions for our plasma device. This research included a study of the DCSBD plasma nanomodification and cleaning effect on the float glass surface and comparison with cleaning using solvents and detergents or an ultrasonic cleaner. This effect was analyzed using modern surface analyses, including the measurement of WCA, SFE, adhesion test, XPS, roughness, and VIS transparency. |
