Abstract
A new method to determine glass corrosion/etching is presented. The method enables a rapid screening of formulations in terms of their glass etching tendency as well as identification of the main components responsible for giving rise to the etching. Up to four formulations can be evaluated during one day. The high sensitivity of the QCM-D instrument enables measuring the etching of thicknesses less than one nm. Therefore, the technique can be used efficiently to screen components in the formulations and aid in the development phase of new optimised dishwash detergent formulations. In a planned work we will investigate the correlation between the etching rate of thin sputtered glass films at the surface of QCM-D crystals and good performance in a standardized dishwasher test using melt-quenched glasses.
Kurzfassung
Es wird eine neue Methode zur Bestimmung der Glaskorrosion präsentiert. Die Methode ermöglicht ein schnelles Screening von Formulierungen sowohl hinsichtlich ihrer Neigung zur Glasätzung als auch der Identifikation des für die hauptsächlich verantwortlichen Inhaltsstoffs. Bis zu vier Formulierungen können pro Tag bewertet werden. Die hohe Empfindlichkeit des QCM-D-Instruments ermöglicht Ätzschichten zu messen, die dünner als 1 nm sind. Daher kann die Technik effizient eingesetzt werden, um Waschmittelformulierungen zu screenen und die Entwicklungsphase von neuen optimierten Geschirreinigerformulierungen unterstützen. In einer geplanten Arbeit wollen wir die Korrelation zwischen der Korrosionsgeschwindigkeit eines dünnen, auf die Oberfläche des QCM-D-Kristalls gesputterten Glasfilms und der guten Leistung in einem standardisierten Geschirreinigertest mit in der Schmelze abgeschrecktem Glas untersuchen.
