After shearingthe recyclate polyol dispersion exhibits a lower Lumisizer Stability Index (indicating improved phase stability). The improved storage stability results in easier storagetransportation and use of the recyclate polyol dispersion.

Sizing and counting of particles from nano-to microscale by single particle light scattering spectroscopy (SPLS): filter media testing AuthorDietmar Lerche, Elia Wollik, Holger Woehlecke Year2024 SourceThe Global Guide 2024-2026 of the Filtration and Separation Industry LanguageEnglish Pages110-115 3003LSpocLUMiSpocFiltration is an important processing step in the production of exceptionally different products 12 more e.g.innovative pharmaceuticals or functionalized inks. Efficiency of filter media and separation membranes play an important role for high quality products. Filter media design and its performance in the production process demand a thoroughly quantitative assessment. Different measuring techniques are used to quantify parameters of filter media relevant to their performance. Important characteristics are filter media materialstypes and structurepermeabilityresistanceproducts to filtrateto name a few. Main fields of use are particle and molecule separationwashing of particlesdewatering. Either the clarified fluid or the solid particles removed from the fluid may be the desired end product. In any casedetermination of pore size and its distribution are of great interest to choose the right filter media for processing. Nominal or absolute pore ratings of filter media are frequently employed. In this paper we describe a recently developed flow cytometer (LUMiSpoc®)which determines simultaneously size and count of micro- and nano-particles at high resolution. This analyser was employed to test the performance of different filter media with nominal sizes from 450 nm to 100 nm. Mixtures of several monodisperse particles were employed to determine the cut-off. On the other handwe used a real-world Titanium dioxide suspension to test the performance. It was shown that filter media made from Cellulose and Nylon behave very differently despite having the same nominal pore size of 450 nm.

Stability of photosensitive zirconia suspensions as a substantive factor for rheological measurements AuthorSOKOLA, P. PTÁČEK, P. KALINA, M. Year2024 SourceFunGlass - Centre for Functional and Surface Functionalized Glass LanguageEnglish Pages3 The stability of suspensions is a key factor not only for determining the dynamic viscosity and rheological behavior of ceramic suspensionsbut also for their practical applications - especially when shaping ceramic bodies. The stability of the suspension is particularly important in DLP (Digital Light Processing) and SLA (Stereolithography) 3D methods of producing green bodieswhen instability and sedimentation of the suspension would lead to the formation of defects or unsuccessful printing. Often used and straightforward method for measuring sedimentation and thus the inhomogeneity of the suspension is the measurement of the level of sedimentation in a cylinder.
